A.示例元件，图1-6。 A. Exemplary elements, Figures 1-6.
[0059] 图1中的附图标记1总体上示出US2005/0166561和PCT W005/63361的可维修过滤元件（空气过滤器滤芯）。 In [0059] FIG. 1 reference numeral 1 shows US2005 / 0166561 and PCT W005 / 63361 Serviceable filter element (air filter cartridge) as a whole. 所示的过滤元件1包括ζ-过滤介质包2，其上设置有空气滤清器密封结构（外壳密封结构）3。 The filter element 1 shown comprises ζ- filter media pack 2, which is provided with an air cleaner seal arrangement (housing seal arrangement) 3.
[0060] 同样，在本文中，术语“空气滤清器密封结构”，“外壳密封结构”及其变化形式一般表示密封结构3以这种方式设置在可维修的过滤元件或滤芯1上，即当过滤元件1安装在空气滤清器中使用时，密封结构3与空气滤清器的适当部件或部分，通常是空气滤清器外壳形成空气密封。 [0060] Also herein, the term "air cleaner seal arrangement", "housing seal arrangement" and variants thereof generally represented in such a seal arrangement 3 provided on a serviceable filter element or cartridge 1, i.e., when the filter element 1 is installed in an air cleaner seal arrangement 3 with the appropriate parts or portions of air cleaner, typically an air cleaner housing to form an air seal. 在本文中，术语“可维修的元件”是指过滤元件1相对于空气滤清器的其他部分是可取出和可更换的。 As used herein, the term "serviceable element" refers to a phase filter element is removable and replaceable with respect to the other portion of the air cleaner.
[0061] 所示的具体空气滤清器密封结构3包括外部径向密封件。 [0061] In particular air cleaner seal arrangement shown in FIG. 3 includes an outer radial seal. 在本文中，术语“外部径向密封件”表示与空气滤清器部件形成密封的表面6，在使用时，是径向向外的，而不是相对于其安装在可维修的过滤元件1的部分上是径向向内的。 As used herein, the term "outer radial seal" means a seal surface 6 of the air cleaner component, in use, a radially outward relative to its mounting instead of the serviceable filter element 1 radially inward portion.

[0068] 现在参见图3。 [0068] Referring now to FIG. 图3是沿图2的线3-3的剖视图。 FIG 3 is a sectional view taken along line 3-3 of FIG 2. 图3的剖面通过图1所示元件1的较短或较窄维数。 FIG 3 a cross-sectional dimension of the shorter or narrower by element 1 shown in Figure 1. 不过，如果截面沿较长的轴，即图2的线YY剖开，可以看到类似的结构。 However, if the cross section along the longer axis, i.e. the line YY of FIG. 2 taken, a similar structure can be seen.
[0069] 图3所示的介质包2是卷绕的介质包。 Media pack shown in [0069] FIG. 32 is a coiled media pack. 一般，介质包2包括波纹介质片材固定至扁平或接近扁平片材，以形成条或单面，其中它以所示形式自身卷绕。 In general, the media pack 2 comprises a corrugated media sheet secured to a flat or nearly flat sheet to form a strip or single-sided, wherein it is shown in the form of wound itself. 因此，介质包2包括单条的波纹片材/扁平或非波纹片材，或单面，如图所示卷绕和构造。 Thus, the media pack 2 comprises a single strip of the corrugated sheet / flat or corrugated sheet, or one surface, and the winding configuration as shown in FIG. 在图2中，尽管示意性地示出介质包，示出了外层的三卷。 In FIG. 2, although shown schematically media pack, the outer layer is shown three volumes. 参见图1，最外卷的外侧尾端用37表示。 Referring to Figure 1, the outside tail end 37 of the outermost winding expressed. 对于所示的实施例，尾端37通过热熔密封剂条38密封并固定在位，尽管其他方案是可行的。 For the embodiment shown, the trailing end 37 sealed by a hot melt sealant strip 38 and secured in place, although alternatives are possible.
[0070] 仍旧参见图3，应当指出，在介质包2中没有示意性地示出中心板，中心间隙， 中心件或中心密封。 [0070] Still referring to FIG. 3, it should be noted, not in the media pack 2 schematically shows the central plate, center gap, center piece or center seal. 在这一点上，介质包2只是示意性示出。 In this regard, the media pack 2 is shown only schematically. 可以使用中心板，例如，在US 6，348，084中有描述，在此被结合入本文。 The center plate may be used, for example, described in US 6,348,084, which is hereby incorporated herein by reference. 可以使用相互交叉的中心条，例如披露于申请日为2003年5月2日的美国临时申请序列号60/467，521。 You can use the center bar crossing each other, for example, disclosed in benefit of US Provisional Application Serial No. 60 / 467,521, 2003 May 2 in. 还可以使用中心密封，例如披露于申请日为2003年5月2日的美国临时申请序列号60/467，521。 You can also use the center of the seal, such as disclosed in benefit of US Provisional Application Serial No. 60 / 467,521, 2003 May 2 in. 对于图3，不对上述及其变化形式进行特定选择。 3 for a particular selection for, and not the above-described variations in FIG.
[0071] 参见图3，所示的预型件部件35包括三个部分，一般包括：外壳密封支撑部分40 ； 介质接合周边或裙边41 ；和介质面横梁结构43。 [0071] Referring to Figure 3, the preform part 35 shown consists of three parts, generally comprising: housing seal support portion 40; media engagement periphery or skirt 41; and media face cross piece arrangement 43.
[0072] 现在参见图4。 [0072] Referring now to FIG. 图4是图3的部分的局部放大图。 FIG 4 is a partially enlarged portion of FIG. 3. 从图4中可以看到，没有预型件35的部分围绕介质包2的外周或侧面加延伸。 As can be seen in FIG. 4, no portion of the preform 35 extends around the outer periphery of the plus or side of the media pack 2. 对于本发明的结构，这种形式是优选的，尽管替代方案是可行的。 For the structure of the present invention, such a form is preferred, although alternatives are possible. 对于图3所示的具体结构，介质接合部分41包括边缘45，它与ζ-过滤介质包2的流动面16接合，并且它不会突出于或者超过流动面16的外周边缘16a。 For the particular configuration shown in FIG 3, media engagement portion 41 includes an edge 45, it ζ- filter media pack 16 engages flow surface 2, and it does not protrude over the flow surface 16 or outer peripheral edge 16a. 所示的具体预型件35包括图6的小隆起45a，它略微伸入介质包2。 DETAILED preform illustrated in FIG 35 includes a small ridge 45a 6, which slightly projects into the media pack 2. 优选的，隆起4¾不大于Imm,并且形成尖点，以助于在形成包胶模36期间容纳上升的氨基甲酸乙酯流体，并且理想地阻止延伸通过流动面16。 Preferably, not more than Imm, 4¾ ridge, and forming a sharp point to facilitate fluid during urethane overmold 36 is formed to accommodate the increase and desirably prevents flow face 16 extending through.
[0073] 如上结合图3所述，应当指出，所示的具体ζ-过滤介质包2包括卷绕的介质结构。 [0073] as described above in connection with Figure 3, it should be noted that the specific ζ- filter media pack 2 shown comprises a coiled media structure. 在图4中，形成了外面的三个卷绕46a，46b和46c。 In FIG. 4, it is formed outside of the three winding 46a, 46b and 46c. 示出了靠近表面16的卷绕46a，46b和46c的端部包括在47处折叠或针刺闭合的端部。 Shows a surface 16 near the winding 46a, 46b and 46c at the end portion 47 comprises a folded end or needle closed. 这种折叠或针刺披露于，例如，申请日为2003年5月2日的美国临时申请序列号60/467，521，在此被结合入本文。 This folding or needling are disclosed in, e.g., U.S. filing date of Provisional Application Serial No. 60 / 467,521 May 2, 2003, and hereby incorporated herein by reference.
[0074] 仍然参见图4，模制的密封部件36设置有部分48覆盖并密封接合处49，在这里预型件部件35结合介质包2的流动面16。 [0074] Referring still to FIG 4, the molding member 36 is provided with a sealing portion 48 covers and seals the joint 49, where the flow face of the media pack 35 in conjunction with 16 of the preform 2 member. 具体地讲，模制的密封部件36包括部分51，它沿远离流动面16的方向延伸超过接合处49 (朝向图3所示的相对流动面15)，超过距离为至少5mm，优选至少8mm，并通常在大约9mm-18mm的范围内，包括端点值。 Specifically, the molding member 36 comprises a sealing portion 51, which in a direction away from flow face 16 extends beyond the joint 49 (FIG. 3 opposite flow faces toward the FIG. 15), preferably at least 5mm over at least a distance of 8mm,, and typically in the range of from about 9mm-18mm, inclusive.
[0075] 一般，模制的密封部件36的部分48和51在该位置提供介质包2和预型件部件35之间的密封，并且还提供环绕并抵靠介质包2，靠近面16密封，以阻止在该区域的不希望的、污染的空气流。 [0075] In general, a sealing member 36 molded portions 48 and 51 provide the media pack 2 and the preform member at the position between the seal 35, and also to provide a surround and against media pack 2, near the sealing surface 16, in the region to prevent undesirable contamination of the air flow.
[0076] 参见图1，特别是热熔密封条38，通常条38是连续的并且止于包胶模36的区域51 的下面，在距离图4的流动面16至少4mm的位置。 [0076] Referring to FIG. 1, in particular a hot melt seal strip 38, strip 38 is generally continuous and ends below region 51 of overmold 36, at the position of FIG. 4 from flow face 16 is at least 4mm. 通常，条38的6_12mm的延伸部分位于包胶模36下面。 Typically, strip 38 extension portion 6_12mm overmold 36 located below. 条38止于距离面16至少4mm处确保了在至少4mm的距离上，包胶模36 的密封材料直接密封至靠近端面16的介质包2。 Article 38 ending at 4mm from the surface of at least 16 ensures that over a distance of at least 4mm, overmold sealing material 36 is sealed directly to the media pack 16 near the end surface 2. 这有助于避免包胶模36和介质包2之间在该位置发生泄露。 This helps to avoid leakage occurs overmold 36 and the position between the media pack 2.
[0077] 参见图4，模制的密封部件或包胶模36还包括空气滤清器密封部分M。 [0077] Referring to Figure 4, molded seal component or overmold 36 further includes air cleaner seal portion M. 空气滤清器密封部分M包括径向外表面56，以优选方式设置，用于与空气滤清器部件密封。 Air cleaner seal portion M includes a radially outer surface 56, in a preferred manner, for sealing with an air cleaner component. 示出了具体表面56为阶梯表面部分56a，它的形状类似于美国专利6，350，291的图7用附图标记250所示出的密封表面部分的形状，该文献的完整内容在此被结合入本文。 56 shows a specific surface of the stepped surface portions 56a, its shape is similar to U.S. Patent No. 6,350,291 is shown in FIG. 7 by reference numeral shape of the sealing surface portion, the complete disclosure of which is hereby 250 incorporated herein by reference.
[0078] 从图3可以看到，预型件部件35的部分40设置以便支撑外壳密封件56和模制密封结构36的阶梯部分56a。 [0078] As seen in Figure 3, the preform member portion 40 is provided so as to support the housing 35 of the sealing member 56 and the stepped portion 56a of molded seal structure 36. 因此，预型件部件35部分起着对密封强度的刚性支撑的作用， 此时在安装到空气滤清器后空气滤清器密封部分M在厚度上受压（通常在压力最大的部分是厚度的至少10% )，压缩是表面56朝向部分40。 Thus, it plays the role of a rigid support part 35 of the seal strength of the preform part, when the air cleaner seal portion M is pressed in the thickness after installation to an air cleaner (usually the largest part of the thickness of the pressure at least 10%), a compression portion 40 toward surface 56. 通常，在密封56的最厚部分56b，压缩距离在1. 5-2. 8mm范围内，经常约1. 9-2. 5mm。 Typically, the thickest portion of the seal 56b 56, the compression distance in the range of 1. 5-2. 8mm, often about 1. 9-2. 5mm.
[0079] 通过面16的表面40从介质包2的外周加的凹进，提供了过滤元件1可以安装在原先设置的空气滤清器中，例如，以接收元件，如被结合入本文参考的美国专利6，350，291 的图15的元件450。 [0079] surface 16 of the surface 40 from the outer periphery of the media pack 2 plus recess, provided the filter element 1 may be mounted in the air cleaner original settings, for example, to receive the member, such as is incorporated herein by reference U.S. Patent No. 6,350,291 to element 450 in FIG. 15. 当然，其他结构是可行的。 Of course, other configurations are possible.
[0080] 介质接合部分41被设置成径向向外延伸，在部分40和边缘57之间延伸。 Extending outwardly [0080] Media engagement portion 41 is disposed radially, extending between the edge portions 40 and 57. 介质接合部分41被设置为自区域40的径向向外裙边。 Media engagement portion 41 is disposed radially outwardly from the skirt region 40. 该向外延伸部分表示在过滤作业期间， ζ-过滤介质包2的出口槽纹端部，在区域60，见图3，不对从其通过的空气闭合。 The outwardly extending portion of the filter means that during operation, zeta-filter media pack outlet end of the groove 2 of the land, in the region 60, shown in Figure 3, no closed air therethrough. 如果区域41不设置为扩口、对角的裙边，而是部分40延伸到点61，区域60的槽纹会被延伸部分41 阻挡，阻止空气从其流过。 If the region 41 is not set to a flared skirt of the angle portion 40 but extending to a point 61, 60 of the groove area extending portion 41 is blocked, preventing air flow therethrough. 这会导致增大的限制，以及介质较低的利用率。 This can lead to increased restrictions, and lower media utilization. 通常图6的角X 在20° -70°的范围内，以容纳需要的裙边。 Angle X in FIG. 6 is generally in the range of 20 ° -70 °, to accommodate the desired skirt. 角度X是裙边41的内表面和介质面16之间的角度。 Angle X is the angle between the inner surface of the skirt 41 and the media surface 16.
[0081] 参见图4，应当指出，对于所示的具体结构，裙边41的大小和位置适合使面16的区域64(对应介质包2的外部槽纹卷46a的出口槽纹的其他开口端)暴露，以便其内容纳部分模制的密封部件36，如66所示。 [0081] Referring to Figure 4, it should be noted that for the particular arrangement shown, the size and position of the skirt 41 is adapted so that the region 64 of surface 16 (corresponding to the external flutes of the media pack outlet flutes 2 volumes of the other opening end 46a ) exposed to the sealing member which houses the molded part 36, 66 as shown in FIG. 这种结构是有利的。 This structure is advantageous. 具体地讲，这使得在模制期间，一些包胶模36升入介质包2，参见下文。 Specifically, this such that during molding, some of overmold 36 ascend the media pack 2, see below.
[0082] 应当指出，对于图4所示的优选元件1，没有模制密封部件36的部分沿部分40的内表面40a设置。 [0082] It should be noted that for the preferred element shown in FIG. 41, no portion of the inner surface 40 of the portion 36 of the molded seal member 40a disposed along. 另外，通常没有模制密封部件36的部分沿区域41的内表面41a设置，除了可能用于紧靠边缘45的某些渗出或覆盖之外。 Further, typically no portion of the molded seal along the region 36 of the inner member 41a surface 41 is provided, in addition to some bleeding or cover edge 45 against the outside may be used. 后者在交付时防止不希望水平的覆盖穿过表面16。 The latter prevents undesirable level of coverage across the surface 16 at the time of delivery.
[0083] 仍然参见图4，介质面横梁结构43延伸穿过介质面16，与预型件部件35的区域41 接合。 [0083] Referring still to Figure 4, media face cross piece arrangement 43 extends through the medium face 16, engagement region 35 of the preform member 41. 在使用期间，介质面横梁结构43阻止介质包2沿图1的箭头10所示方向压缩。 During use, the media face cross piece arrangement 43 prevents the media pack 2 in a direction indicated by arrow 10 in FIG. 1 compression.
[0084] 可以使用多种横梁结构。 [0084] The various beam structures may be used. 在图2中，所示的具体横梁结构43包括：相对侧22，23 之间平行延伸部分43a的格栅；由对角框架4¾相互连接。 In FIG. 2, the specific structure shown in the cross member 43 comprising: a grill portion 43a extending in parallel between opposite sides 22, 23; manufactured by diagonal frame 4¾ interconnected.
[0085] 在图5中，提供了透视图，示出预型件部件35。 [0085] In Figure 5, a perspective view illustrating the preform member 35. 可以看到，预型件部件35可以形成为单个一体装置，例如通过注模或其他模制工艺。 It can be seen that the preform part 35 may be formed integrally as a single device, such as by injection molding or other molding process. 它通常用聚合物制成，如（例如33%) 玻璃填充的尼龙材料。 It is usually made from polymers, such as (e.g., 33%) glass filled nylon material.
[0086] 再次参见图4，模制的包胶模或密封部件36包括部分70，覆盖预型件部件35的部分端部71。 [0086] Referring again to FIG. 4, molded overmold or seal component 36 includes a portion 70 covering an end portion of the preform member 71 35. 它是来自优选的模制作业的人造品，如下文所述。 It is an artifact from a preferred molding operation, as described below.
[0087] 参见图4，应当指出，在横梁43接合裙边41的地方，裙边41相对表面16的角度可能被略微中断。 [0087] Referring to Figure 4, it should be noted that the cross member 43 where the engagement of the skirt 41, the angle of the skirt 41 opposite the surface 16 may be slightly interrupted. 不过，一般，在其他位置，裙边41具有上述的优选角度X。 However, in general, at other locations the skirt 41 having the above-described preferred angle X.
[0088] US公开号2005/0166561和PCT W005/63361所述的技术可以适用于多种元件结构和尺寸。 [0088] US Publication No. 2005/0166561 and PCT W005 / 63361 in the art can be applied to a variety of configurations and sizes element. 以下尺寸仅为示例，以助于理解所述技术的广泛应用。 The following dimensions are merely exemplary to facilitate understanding of the technique is widely used. 包胶模36，在其最厚部位，可以是大约10-12mm厚，例如约11.5mm。 The overmold 36, in its thickest portion, may be about 10-12mm thick, for example about 11.5mm. 跑道形状介质包的最长截面尺寸可以为大约300-320mm，例如约308mm。 Longest cross-sectional dimension of the racetrack shaped media pack could be about 300-320mm, for example about 308mm. 跑道形状元件的最短截面尺寸可以为大约115_125mm，例如约121mm。 The shortest cross-sectional dimension of the racetrack shaped element could about 115_125mm, for example about 121mm. 直边的长度可以为大约175_195mm，例如约188mm。 The length of the straight edge may be about 175_195mm, for example about 188mm.

Alternatively the skid skirt (30,104) placed at one end of the sealing element opposite.
[0098] 在本文中，“包胶模制”及其变化形式是指，将模制的密封部件36，111在位模制： (a)使模制密封部件36的部分覆盖密封结构的预型件部件（35，110)和介质包（2，102)之间的接合处外侧；和，（b)设置相同的密封部件36，111的部分（即优选与包胶模的其余部分成一体的部分），以形成空气滤清器密封。 [0098] As used herein, "overmolding" and variants thereof means that the molded sealing member 36, 111 molded in place: (a) that the molded seal member 36 covering the portion of the pre-sealed structure the outer joint member between the type member (35,110) and a media pack (2, 102); and a remaining portion, portion (i.e., preferably the same overmold sealing member (b) is provided integrally 36,111 portions), to form an air cleaner seal. 对于形成模制密封部件，通常和优选的方法会使用泡沫聚氨酯，如下文所述。 For the formation of the molded seal component, and generally preferred method it uses polyurethane foam as described below. 在这里，如上述定义通过包胶模制制成的模制密封部件36， 有时被称为包胶模。 Here, as defined above, by overmolding made of molded seal component 36, sometimes referred to as an overmold. 包胶模密封的部分优选彼此成一体；包胶模36，111优选从单个聚合物池模制而成。 Overmold seal portion is preferably integral with each other; overmold preferably 36,111 packets from a single molded polymer pool.
[0099] 通常，模制密封部件在密封表面区域的厚度是这样设置的，使得模制密封部件在该区域最厚部分的压缩厚度，是至少10%，并通常至少15%，此时元件（1，101)安装在空气滤清器中以供使用。 [0099] Generally, the thickness of the molded seal member of the sealing surface area is provided, so that the molded seal member compressed thickness of the thickest portion of the region is at least 10%, and typically at least 15%, at this time element ( 1,101) installed in an air cleaner for use. 这可以通过所示结构实现，使用下述材料。 This can be achieved by the structure shown, using the following materials.
[0100] 下面将结合图11-16说明通常的方法。 [0100] 11-16 described below in conjunction with FIG conventional method.
[0101] 首先参见图11。 [0101] Referring first to FIG. 11. 在图11中，附图标记180表示可用于形成图1-10的包胶模密封结构的模具结构。 In Figure 11, reference numeral 180 denotes a mold structure overmold seal arrangement of Figures 1-10 may be used to form. 模具结构180以局部剖视图的形式示出。 Mold structure 180 shown in the form of a partial cross-sectional view. 所示出的部分可以提供对如何形成包胶模密封结构的理解。 Portion shown may be formed to provide an understanding of how the overmold seal arrangement. 模具的其余部分可根据具体的用途被设置成圆形或长圆形寸。 The remaining portion of the mold may be provided or oblong inch depending upon the particular use.
[0102] 参见图11，示出的具体模具结构180是多部分模具181。 [0102] Referring to Figure 11, specifically mold structure 180 is shown multi-part mold 181. 就是说，模具180包括多于一件匹配在一起，以形成模具，其中发生包胶模制过程。 That is, the mold 180 includes more than one matched together to form a mold, which occurs overmolding process. 所示的具体多部分模具180包括三个部分183，184和185，它们匹配在一起，以形成模具。 In particular multi-part mold 180 shown comprises three sections 183, 184 and 185, which mate together to form the mold. 孔189，当三个部分183，184，185 适当对齐时延伸通过它们，图11，可用于容纳销或类似件，以将模具固定在一起。 Bore 189, extending in three parts 183,184,185 when aligned by their proper, FIG. 11, may be used to receive a pin or the like, secured together to the mold.
[0103] 一般，部分183形成基本模具结构，包括：内部容器部分192，其中放置未凝固的树脂，用于模制过程；内壁193，使用时预型件部件会抵靠其放置；支架194，在模制过程中可将预型件部件的边缘搁置其上；中央壁195和支架196，支撑所述的其他模具部分；和外壁197，它为组件180提供外部支撑结构。 [0103] In general, the basic mold structure portion 183 is formed, comprising: an inner container portion 192, wherein the uncured resin is placed, for the molding process; inner walls 193, using the preform member may placed against; cradle 194, in the molding process of the preform part edge can rest thereon; central wall 195 and the bracket 196, the support of the other portions of the mold; and an outer wall 197, which provides an outer support structure assembly 180.
[0104] 第二部分184包括模具插入件，它具有延伸部分200，具有表面201，在使用时形成密封结构的模制部分的外表面的部分。 [0104] The second portion 184 comprises a mold insert, which has an extension 200 having a surface 201, part of the outer surface of the molded portion is formed of a sealing structure in use. 在这里，表面201包括部分202，它与中央壁195 结合，提供模具底切203，模制所得到密封部分的密封表面的特定部分，如下文结合图15所述。 Here, surface 201 includes a portion 202, which in combination with central wall 195 provides a mold undercut 203 molding a particular portion of the sealing surface of the sealing portion is obtained, as described below in connection with FIG. 15. 部分184还包括上部延伸部分205，它搁置在肩部196上。 Section 184 further includes an upper extension 205 which rests on the shoulder 196.
[0105] 最后，部分185包括内壁215和上凸缘218。 [0105] Finally, portion 185 includes an inner wall 215 and upper flange 218. 凸缘218伸过中央部分184的部分205。 218 extending through the central portion 205 of the flange portion 184. 内壁215包括表面216，它在模制过程中形成密封件的选定部分，如下文结合图15所述。 Selected portions of the inner wall 215 includes a surface 216 which forms a seal during the molding process, as described below in conjunction with FIG. 15. 如上所述，在模制作业期间，部分217覆盖模具，并且接合介质。 As described above, during the molding operation, the mold cover portion 217 and engage the media.
[0106] 现参见图12，其中示出的组件180具有可凝固材料225置于容器192中，达到注满线226。 [0106] Referring now to FIG. 12, in which the assembly 180 shown in line 226 having a filled settable material 225 placed in the container 192 reaches. 材料225—般包括树脂，它在凝固过程中，会发泡和上升为凝固物，以形成可模制的密封部件。 225- like material includes a resin, which during the solidification process, will foam and rise as a coagulum to form a moldable sealing member. 通常，在模制期间，使用材料225的体积会膨胀至少80%，优选材料的体积增加约100%。 Typically, during molding, the volume of a material 225 may expand at least 80%, preferably by about 100% by volume of the material.
[0107] 在图13中，示出了其内具有树脂225的模具组件180中具有预型件部件230。 [0107] In FIG. 13, which shows the mold assembly 180 having resin 225 having preform member 230. 预型件部件230可对应于，例如，图1的预型件部件35。 The preform member 230 may correspond to, for example, the preform member 35 in FIG. 1. 它也可对应于图7的预型件部件110。 It may also correspond to preform part 110 in FIG. 7. 不过，如果用于图7的结构，在某些情况它会已经连接至介质包。 However, if the structure used in FIG. 7, in some cases it has been connected to the media pack.
[0108] 现参见图14，其中示出的模具结构180具有适当定位的预型件部件230和介质包231。 [0108] Referring now to FIG. 14, in which the mold 180 having the structure shown in preform member 230 and media pack 231 positioned appropriately. 应当指出，介质包231的外表面232的大小适合接合模具部分185的部分217。 It is noted that media pack 231, the size of the outer surface 232 of the portion 217 adapted to engage portion 185 of the mold.
[0109] 现参见图15。 [0109] Referring now to FIG. 15. 在图15中，235处的材料表示发泡的、上升的大体凝固的树脂；即， 包胶模（对应图1的包胶模36，或图7的包胶模10；3)。 In Figure 15, the material at 235 represents foamed, substantially cured resin rises; i.e., the overmold (corresponding to overmold 36 of FIG. 1 or FIG overmold 107; and 3). 术语“大体凝固”表示树脂充分凝固，已达到一形状，随着进一步凝固该形状大致被保持。 The term "substantially cured" means sufficiently solidified resin, a shape has been reached, with further solidifying the shape is substantially maintained. 从图15，可以理解下述有关模制作业的一些重要特征：1.在区域对0，形成了模制密封部件235的最外突出部分（编号与上文相同）。 From FIG 15, it is understood some important features relating to the molding operation the following: 1. In the region of 0, the outermost projecting portion formed (the same number as above) molded seal member 235. 然后，部分240会形成向外径向密封件的最外部分，即，在使用中作为空气滤清器密封最受压的部分；2.表面241是模具底切的部分，用于形成区域MO的部分。 Then, portion 240 formed outwardly radially outermost portion of the seal, i.e., in use as an air cleaner seal portion of most compression; 2. the mold surface 241 is undercut portion for forming region MO part. 3.在区域245,围绕介质包231的外表面232上升的材料235被模具件185覆盖或阻挡，尤其是被模具件185的区域216。 3. In the region 245, around the outer surface 231 of the media pack 232 rises mold material 235 is covered or barrier member 185, in particular by region 185 of the mold member 216.
[0110] 在位置M7，某些包胶模235的树脂已升入介质包，在介质包231的最外层248和其下层之间。 [0110] In the position M7, some of the resin of overmold 235 has been promoted to the media pack, the media pack between the outermost layer and lower layer 248,231. 该上升倾向于闭合在该位置的任何其他开口槽纹。 This tends to increase any other openings in the flute closure position. 一般，这会使得介质包的最外层（例如，图4的层46a)，在被用于过滤材料时，空气在排出介质包之前，必须进入下一个内层。 Typically this will make the outermost layer of the media pack (for example layer, 46a in FIG. 4), when the filter material is used, air prior to discharging the media pack, must enter the next inner layer. 这意味或者确保了即使介质包的最外卷在处理或安装期间受损，也不会导致泄露。 This ensures that even means or outermost winding of the media pack damaged during handling or installation, it does not lead to the disclosure. 因此，在以这种方式制成的通常结构中，在介质包中存在两端闭合的第三组槽纹。 Thus, in the conventional structure made in this way, there is a third set of flutes is closed in both ends of the media pack. 这第三组槽纹优选只存在于最外卷。 This third set of flutes preferably exists only in the outermost winding. 所述槽纹否则是出口槽纹，并且有时候会用这样的术语表示。 The flutes would otherwise be outlet flutes, and will sometimes expressed in such terms.
[0111] 对于图11-16所示的方法，介质包在入口槽纹具有闭合端，靠近出口流动面，针刺闭合，以提供可见的边缘。 [0111] For the method shown in FIGS. 11-16, the media pack having inlet flutes at the closed end, adjacent to the outlet flow face, darted closed, to provide a visual edge. 其他方案当然是可行的，包括根本不用针刺。 Of course, other scenarios are possible, including do not have acupuncture. 示出了包胶模材料升入出口槽纹的开口端，位于介质的出口面，在用247表示的区域。 Shows an overmold material promoted open end of the outlet flutes, medium outlet face is located, with the region 247 indicated.
[0112] 沿区域M9，250，树脂材料236完全填充预型件230的外表面，使其固定在位。 [0112] in the region M9,250, the resin material 236 completely fills the outer surface of the preform 230, to secure it in place. 在区域255，材料235设置覆盖预型件230的端部256的部分。 In region 255, material 235 is provided to cover the end portion 256 of the portion 230 of the preform.
[0113] 在所示的具体结构中，见图15，包胶模235是单个一体件，由树脂225模制，见图14。 [0113] In the particular arrangement shown in Figure 15, the overmold 235 is a single integral member, molded from resin 225 (Figure 14).
[0114] 脱模可以通过在用动力过程中迫使元件脱开模具180来实现。 [0114] releasing the mold can be released by forcing the element 180 is achieved with a power process. 产生动力的设备可以接合预型件230上的横梁。 Generating power apparatus may engage the cross member 230 on the preform. 一般，包胶模235会充分压缩，以被推动通过模具的底切。 Typically, the overmold 235 will compress sufficiently, to be pushed through the bottom die cut. 通常预期的是，通过本文所披露的材料和结构，可以用110磅或更小的力，通常大约100磅的力来实现脱模（脱模的力通常直接施加在预型件35，110的格栅件上）。 Generally contemplated that disclosed herein by the materials and structures, can be 110 lbs or less of force, usually about 100 pounds of force to achieve release (release force is usually applied directly to the preform 35,110 grid member).
[0115] 位于元件相对端的可选预成型防滑裙边可以在模制之前或之后应用。 [0115] located at opposite ends of the element optional preform skid skirt may be applied before or after molding. 一般，如果在介质中使用中央塞，它会在所述模制过程之前预成型。 In general, if the medium using central plug, it will be preformed prior to the molding process. 不过，在某些情况，中央塞可以与包胶模同时模制。 However, in some cases, the central plug may be molded simultaneously with the overmold. 后者需要确保，提供模具或某些其他结构的部分，用于适当地分配氨基甲酸酯，来实现上述目的。 The need to ensure the latter, providing a mold, or some other part of the structure, for appropriately allocating a urethane, to achieve the above object.
[0116] 应当指出，在某些情况，如上所述，预型件230可以通过搭扣配合结构连接至介质包231。 [0116] It should be noted that, in some cases, as described above, the preform 230 may be connected to the media pack 231 by snap-fit ​​structure.
[0117] 在图16中，示出的模具180具有模制时置于其内的介质包231和预型件230。 [0117] In FIG. 16, the mold 180 is shown within the media pack 231 and preform 230 having the molding. 在这里，示出的介质包231没有安装其上的可选防滑裙边。 Here, the media pack 231 is shown without the optional skid skirt mounted thereon.
D.可选的防滑裙边 D. Optional skid skirt
[0118] 在上文结合图1的讨论中，指出防滑裙边30是可选部件。 [0118] discussed above in conjunction with FIG. 1, indicated skid skirt 30 is an optional component. 该部件在图17和18中示出。 The member shown in FIGS. 17 and 18.
[0119] 首先参见图17，示出了防滑裙边30的俯视平面图。 [0119] Referring first to FIG. 17, there is shown a top plan view of the skid skirt 30. 在图18中，示出了防滑裙边30的剖视图。 In FIG 18, illustrates a cross-sectional view of the skid skirt 30. 参见图18，可以看到介质包的接纳区域30a，连同外表面30b，被设置成在安装期间根据需要接合外壳中的部件。 Referring to Figure 18, we can see the media pack receiving area 30a, together with the outer surface 30b, the housing member is disposed in engagement needed during installation. 根据图17和18所示的原理，可以理解类似的但是圆形的部件，如果需要的话，可用于圆形结构。 According to the principle shown in FIGS. 17 and 18, it will be appreciated that a similar circular member, if desired, can be used for circular structure. 防滑裙边30通常由玻璃填充（例如33%玻璃填充的）尼龙形成，用黏合剂固定在位。 Skid skirt 30 is typically filled with a glass (e.g., 33% glass filled) nylon is formed with adhesive in place.
E.可凝固的密封树脂 E. solidifiable sealing resin
[0120] 通常通过所述结构，所选的聚氨酯配方提供高泡沫、极柔软的模制端盖。 [0120] generally by the structure, the polyurethane formulation chosen provides a high foam, very soft, molded end cap. 一般，主要问题是利用提供端盖的配方，所述端盖是这样的，在一定条件下会得到坚固密封，它允许手工组装和拆卸。 In general, the main problem is to provide the use of end cap formulation, the end cap is such that, under certain conditions the seal will be strong, which allows the manual assembly and disassembly. 这大体表示，密封所用材料的范围是较低密度的，并表现出适当和理想的压缩载荷挠度和压缩形变。 It is generally said that the scope of the sealing material used is a relatively low density, and exhibits appropriate and desirable compression load deflection and compression set.
[0121 ] 通常，所选的配方是这样的，端盖的模制密度不大于观磅/立方英尺，通常不大于22磅/立方英尺，经常不大于18磅/立方英尺，并优选在12-17磅/立方英尺的范围内。 [0121] Generally, the formulation is selected such that the end cap is molded density of no greater than Concept pounds / cubic foot, typically no greater than 22 lbs / cubic foot, often no greater than 18 lbs / cubic foot, and preferably 12- 17 lbs / cubic foot range.
[0122] 在本文中，术语“模制密度”是指，重量除以体积的标准定义。 [0122] As used herein, the term "molded density" means the weight divided by the standard defined volume. 可以利用水置换测试或类似测试来确定模制泡沫样品的体积。 Testing may be substituted or the like tests to determine the volume of the molded foam sample with water. 在进行体积测试时，没有必要求水吸收进入多孔材料的孔中，并置换孔所代表的空气。 During the test volume, it is not necessarily required water absorption into the pores of the porous material, and represented by the replacement air holes. 因此，使用的水量置换测试来确定样品体积是立即置换，不需要长时间等待以置换材料孔中的空气。 Thus, the amount of water used permutation test to determine sample volume was immediately replaced, it does not need to wait a long hole to displace material in the air. 换句话说，只需要用样品外周所表示的体积，用于模制密度计算。 In other words, just use the sample volume represented by the outer periphery, a molded density calculation.
[0123] 一般，压缩载荷挠度是物理特征，它表示坚固度，即抗压缩性。 [0123] In general, compression load deflection is a physical characteristic that indicates firmness, i.e. resistance to compression. 一般，它通过使给定样品的厚度变形25%所需的压力量来测量。 Usually, it is required to measure the deformation amount of pressure by 25% of a given sample thickness. 压缩载荷挠度试验可以按照ASTM3574进行，在此被结合入本文。 Compression load deflection tests can be carried out in accordance with ASTM 3574, incorporated herein by reference herein. 一般，压缩载荷挠度可以结合旧样品进行评估。 In general, compression load deflection may be evaluated in conjunction with the old sample. 通常的技术是对样品进行压缩载荷挠度测量，所述样品已在75° F下完全固化72小时或者在190° F下强制固化了5小时。 The usual technique is to measure the compression load deflection sample, the sample is fully cured for 72 hours at 75 ° F or forced cured at 190 ° F for 5 hours.
[0124] 优选的材料是这样的，在模制时，示出在158° F的温度下加热老化七天之后的样品上测得的压缩载荷挠度，按照ASTM3574，平均为14psi或以下，通常在6-14psi的范围内， 并优选在7-lOpsi的范围内。 [0124] Preferred materials are such that during molding, is shown at a temperature of 158 ° F heat aging measured compression load deflection on samples after seven days according to ASTM 3574, an average of 14psi or less, typically 6 -14psi within the scope of, and preferably in the range of 7-lOpsi.
[0125] 压缩形变是在解除压缩力之后，材料样品（受到定义类型的压缩并在定义条件下）恢复到其先前厚度或高度的程度的评估。 [0125] Compression set is after the compression force is released, the material samples (defined by the type of compression and under defined conditions) is restored to its previous thickness or height of the degree of evaluation. 评估氨基甲酸乙酯材料的压缩形变的条件同样在ASTM3574中提供。 Compression set evaluation conditions urethane material is also provided in ASTM3574.
[0126] 通常希望的材料是这样的，一旦固化，材料具有的压缩形变不大于大约18%，并通常大约8-13%，当测定样品被压缩到其高度的50%并且在180° F下保持那样的压缩22小时。 [0126] Generally such materials are desirable, once cured, the material having a compression set of no greater than about 18%, and typically about 8-13%, when a measurement sample is compressed to 50% of its height at 180 ° F and in keep the compression as 22 hours.
[0127] 一般，压缩载荷挠度和压缩形变特征可由用于形成端盖的相同树脂制成的样品塞测量，或用从端盖切割下来的样品进行测定。 [0127] In general, compression load deflection and compression set characteristics can be measured sample plug made of the same resin used to form the end cap, or a cap cut out from a measurement sample. 通常，工业加工方法涉及定期制备由树脂材料制成的测试样品塞，而不是直接测试从模制的端盖切割下来的部分。 Typically, industrial processing methods involve a periodic test samples were prepared a plug made of a resin material, rather than direct testing cut from molded end caps down portion.
[0128] 可用于提供具有在上述模制密度，压缩形变和压缩载荷挠度定义内的物理特性的材料的氨基甲酸乙酯树脂系统，可以方便地从多个聚氨酯树脂配方设计者处获得，包括如BASF公司，Wyandotte MI，48192这样的供应商。 [0128] may be used to provide a urethane resin system material having the above-described molded density, compression set and compression load deflection physical characteristics within the defined, can be conveniently obtained from a plurality of the polyurethane resin formulators, including such BASF Corporation, Wyandotte MI, 48192 such suppliers.
[0129] 一般，通过任何给定的工业方法来选择材料的合适物理特征，关键问题是希望特征和最终产品的管理，涉及元件的安装和拆卸，以及在多种条件下密封的保持。 [0129] In general, the physical characteristics suitable material is selected by any given industrial process, the key issue is the final desired product characteristics and management involving the installation and removal elements, and a seal is kept under various conditions. 上述的物理特征是可用的，但并不对可行的产品进行具体限制。 The above physical characteristics is available, but not to be specifically limited viable product. 另外，不同的元件制造商，根据情况， 可能希望进一步地说明，例如，低温压缩变形，通常在冷却到-40° F的样品上测量，规定在ASTM测试下导致压缩所需要的压力例如是IOOpsi (最大）。 Further, various component manufacturers, in some cases, it may be desirable to further illustrate, for example, low compression set, typically measured on the sample cooled to -40 ° F, results in a predetermined compression pressure required in the ASTM test, for example, IOOpsi (maximum).
[0130] 一种示例可用材料包括以下聚氨酯，加工成的最终产品具有“模制”密度为14-22 磅/立方英尺。 [0130] One example usable material includes the following polyurethane, processed to a final product having a "molded" density of 14-22 pounds / cubic foot. 聚氨酯包括用I36070R树脂和I3050U异氰酸酯制成的材料，由BASF公司， Wyandotte, Michigan48192专门销售给受让人唐纳森公司。 Comprises a polyurethane resin material I36070R and I3050U isocyanate made by BASF Corporation, Wyandotte, Michigan48192 sold exclusively to the assignee Donaldson.
[0131] 材料通常以100份I36070R树脂对45. 5份I3050U异氰酸酯（按重量计）的混合比例进行混合。 [0131] materials are typically mixed in a mixing ratio of 100 parts I36070R resin to 45.5 parts I3050U isocyanate (by weight). 树脂的比重为1. 04 (8. 7磅/加仑)，而异氰酸酯为1. 20 (10磅/加仑）。 Specific gravity of the resin is 1.04 (8.7 lbs / gal), and the isocyanate is 1.20 (10 lbs / gallon). 材料通常通过高动态剪切混合器混合。 Materials are typically mixed by a high dynamic shear mixer. 成分的温度应为70-95° F。 Temperature component should be 70-95 ° F. 模具温度应为115-135° F。 The mold temperature should be 115-135 ° F.

F. ζ-过滤介质概述 F. ζ- filter medium Overview
[0134] 上文大体讨论了可用于所述结构的介质包，例如，介质包2，102，包括ζ-过滤介质包。 [0134] generally discussed above may be used for the media pack of the structure, e.g., 2,102 media pack comprising filter media pack ζ-. 表明多种其他槽纹形状和密封类型可用于所述介质包。 It showed that a variety of other flute shapes and seal types can be used for the media pack. 1.Z-过滤介质结构，概述 1.Z- filter media structure outlining
[0135] 槽纹过滤介质可用于以多种方式提供流体过滤器结构。 [0135] fluted filter media can be used in various ways to provide fluid filter constructions. 一种公知的方法是作为ζ-过滤器结构。 A known method as ζ- filter structure. 在本文中，术语“ζ-过滤器结构”是指这样的过滤器结构，其中，各个波纹状的、折叠的或以其他方式形成的过滤槽纹被用于形成成组的纵向、通常平行的入口和出口过滤槽纹，以便流体流过介质；流体沿槽纹的长度方向在介质的相对入口和出口流动端(或流动面）之间流动。 As used herein, the term "zeta-filter construction" is meant a filter structure, wherein each corrugated, folded or formed filter flutes are used to otherwise form a longitudinal, generally parallel groups of inlet and outlet filter flutes for fluid flow through the media; longitudinal direction of the fluid flow along the flutes between opposite inlet and outlet ends of the media flow (or flow faces). Z-过滤介质的一些例子可以参见美国专利5，820，646 ；5, 772,883 ； 5，902，364 ；5，792，247 ；5，895，574 ；6，210，469 ；6，190，432 ；6，350，296 ；6，179，890 ； 6，235，195 ；Des. 399，944 ；Des. 428，128 ；Des. 396，098 ；Des. 398，046 ；和Des. 437，401 ；上述十五份参考文献的每一份在此均被结合入本文。 Some examples of Z- filter media can be found in U.S. Patent No. 5,820,646; 5, 772,883; 5,902,364; 5,792,247; 5,895,574; 6,210,469; 6,190,432 ; 6,350,296; 6,179,890; 6,235,195;.

[0136] 一种类型的ζ-过滤介质，利用两个特定的介质部件结合在一起，以形成介质结构。 [0136] One type of ζ- filter media, utilizes two specific media components joined together, to form the media construction. 这两个部件是：（1)槽纹（通常是波纹状）介质片材；和，(2)表面介质片材。 The two components are: (1) a fluted (typically corrugated) media sheet; and, (2) a facing media sheet. 表面介质片材通常是非波纹状的，不过它可以是波纹状的，例如，垂直于槽纹方向，如申请日为2004 年2月11日的美国临时申请60/543，804中所描述，该文献在此被结合入本文。 The facing media sheet is typically non-corrugated, however it can be corrugated, for example perpendicularly to the direction of the groove pattern, such as the filing date of U.S. Provisional Application 60 / 543,804 described February 11, 2004, which is It is hereby incorporated herein by reference.
[0137] 槽纹（通常为波纹）介质片材和表面介质片材一起用于形成具有平行的入口和出口槽纹的介质。 [0137] fluted (typically corrugated) media sheet and the facing media sheet together for forming medium having an inlet and outlet flutes parallel. 在某些情况，槽纹片材和表面片材固定在一起，然后被卷绕以形成ζ-过滤介质结构。 In some instances, the fluted sheet and facing sheet are secured together, and then wound to form ζ- filter media construction. 所述结构披露于，例如，US 6，235，195和6，179,890中，它们各自在此被结合入本文。 The structure disclosed in, e.g., US 6,235,195 and 6,179,890 in each of which is incorporated herein by reference herein. 在某些其他结构中，槽纹介质的一些非卷绕部分固定至表面介质，彼此层叠，以形成过滤器结构。 In certain other arrangements, some non-coiled sections of fluted media secured to facing media, are stacked with each other, to create a filter construction. 这种结构的示例披露于5，820，646的图11，在此被结合入本文。 An example of such configuration is disclosed in FIG. 11 of 5,820,646, incorporated herein by reference herein.
[0138] 对于本文所述的特定应用，优选卷绕结构。 [0138] For the particular application described herein, coiled arrangements are preferred. 通常，槽纹片材/表面片材组合围绕自身卷绕，以形成卷绕的介质包，使表面片材向外。 Typically, the fluted sheet / facing sheet combination around itself wound to form a coiled media pack, the surface of the sheet outwardly. 卷绕的一些技术披露于申请日为2003年5 月2日的美国临时申请60/467，521，和申请日为2004年3月17日的PCT申请US04/07927， 它们各自在此被结合入本文。 Some technical wound disclosed in US provisional application filing date of May 2, 2003 and 60 / 467,521, and PCT application filed March 17, 2004 of US04 / 07927, each of which is incorporated herein This article. 所得到的卷绕结构一般具有部分表面片材作为介质包的外表 The resulting coiled arrangement generally has, as the outer portion of the surface of the sheet media pack
[0139] 本文所使用的术语“波纹的”是指介质结构，表示使介质通过两个波纹辊之间，即， 进入两个辊之间的辊隙或咬合部分所得到的槽纹结构，这两个辊各自具有适合在最终介质造成波纹效应的表面特征。 [0139] As used herein, the term "corrugated" refers to a medium structure, represented by the medium is between two corrugation rollers, i.e., into the flute structure nip or bite between two rollers obtained, which two rollers each having a corrugated surface features resulting in effect for the final media. 术语“波纹”不是指不涉及使介质通过波纹辊之间的咬合部分的技术而形成的槽纹。 The term "corrugation" is not means not involving passage of media art by the nip portion formed between the flutes of the corrugated rolls. 不过，术语“波纹的”适用于在形成波纹之后即使介质被进一步改进或变形，例如，通过披露于公开日为2004年1月22日的PCT W004/007054的折叠技术，该文献在此被结合入本文。 However, the term "corrugation" applies to after formation of the corrugated even if the media is further improved or modified, e.g., by the disclosure in the publication date PCT folding techniques W004 / 007054 of 2004 January 22, which is hereby incorporated herein incorporated herein.
[0140] 波纹介质是槽纹介质的特定形式。 [0140] Corrugated media is a specific form of fluted media. 槽纹介质是具有各个槽纹（例如，通过压制波纹或折叠的技术而形成）延伸穿过其间的介质。 Fluted media is media having individual flutes (for example, formed by corrugating or folding techniques) extending through the dielectric therebetween.
[0141] 采用ζ-过滤介质的可维修过滤元件或过滤器滤芯结构有时候被称作“直通流动结构”或其变化形式。 [0141] The filter media ζ- Serviceable filter element or filter cartridge arrangement is sometimes referred to as "straight through flow configurations" or by variants thereof. 一般，在本文中表示，可维修的过滤元件一般具有入口流动端（或面） 和相对的出口流动端（或面），流体进入和离开过滤器滤芯大体上是相同的直通方向。 In general, herein expressed, the serviceable filter elements generally have an inlet flow end (or face) and an opposite exit flow end (or face), the fluid entering and exiting the filter cartridge in generally the same straight through direction. 在本文中，术语“可维修的”是指，含有介质的过滤器滤芯定期从相应的流体滤清器取出并更换。 As used herein, the term "serviceable" means a media containing filter cartridge is periodically removed from the filter and replace the corresponding fluid. 在某些情况，每个入口流动端和出口流动端大体是扁平或平面状的，两者彼此平行。 In some cases, each of the inlet flow end and outlet flow end will be generally flat or planar, with the two parallel to one another. 不过， 其变化形式，例如非平面的表面是可行的。 However, their variations, for example non-planar faces are possible.
[0142] 例如，直通流动结构（尤其对于卷绕的介质包），不同于可维修的过滤器滤芯如美国专利号6，039，778所披露的圆柱状折叠过滤器滤芯类型，其中流体在通过可维修的滤芯时一般转向，该专利在此被结合入本文。 [0142] For example, straight through flow configuration (especially for a coiled media pack), different from the serviceable filter cartridge as disclosed in U.S. Patent No. 6,039,778 cartridge type cylindrical pleated filter, wherein the fluid through Usually steering serviceable cartridge, which patent is incorporated herein by reference. 就是说，在6，039，778的过滤器中，流体通过圆柱状侧面进入圆柱状过滤器滤芯，然后转向通过端面排出（在顺流系统）。 That is, in a 6,039,778 filter, the flow through a cylindrical side enters the cylindrical filter cartridge through an end face and then turned to the discharge (in forward-flow systems). 在通常的逆流系统中，流体通过端面进入可维修的圆柱状滤芯，然后转向通过圆柱状过滤器滤芯的侧面排出。 In a typical reverse-flow system through which fluid enters the end face of the serviceable cylindrical cartridge, and then discharged through a side of the steering cylindrical filter cartridge. 这种逆流系统的例子参见美国专利号5，613，992，在此被结合入本文。 Examples of such a countercurrent system described in US Patent No. 5,613,992, hereby incorporated herein by reference.
[0143] 在本文中使用的术语“ζ-过滤介质结构”及其变化形式是指下述任一或者所有结构：波纹或其他槽纹介质固定至表面介质的网，具有适当密封，以允许形成入口和出口槽纹；或者，所述介质卷绕或以其他方式构造或者形成三维入口和出口槽纹网络；和/或，包括所述介质的过滤器结构。 [0143] The terminology used herein, "zeta-filter media construction" and variants thereof refers to any one or all of the following structures: a corrugated or otherwise fluted media secured to facing media with appropriate sealing to allow for the formation inlet and outlet flutes; or, such a media coiled or otherwise constructed or formed in a three-dimensional network inlet and outlet flutes; and / or, a filter construction including the media.
[0144] 在图19中，示出了可用于ζ-过滤介质的介质401的例子。 [0144] In FIG 19, it illustrates an example of filter media may be used ζ- medium 401. 介质401由波纹（槽纹)片材403和表面片材404形成。 404 is formed from corrugated media 401 (fluted) sheet 403 and the facing sheet.
[0145] 一般，图19所示的波纹片材403的类型在本文一般被表征为具有规则的，弯曲波型的槽纹或波纹407。 [0145] In general, the corrugated sheet 403 shown in FIG. 19 of the type generally characterized herein as having a regular, curved, wave pattern of flutes or corrugations 407. 在本文中，术语“波型”是指交替的波谷407b和波峰407a的槽纹或波纹型式。 As used herein, the term "wave pattern" refers to alternating troughs 407b and ridges 407a pattern of flutes or corrugations. 在本文中，术语“规则的”是指，波谷和波峰对（407b，407a)交替，具有大体相同的重复波纹（或槽纹）形状和大小。 As used herein, the term "regular" refers to troughs and ridges (407b, 407a) alternate with generally the same repeating corrugation (or flute) shape and size. （另外，通常在规则的结构中，每个波谷407b基本上是每个波峰407a的倒置）。 (Also, typically in a regular configuration each trough 407b is substantially an inverted each ridge 407a). 因此，术语“规则的”表示波纹（或槽纹）型式包括每对波谷和波峰（包括相邻的波谷和波峰）重复，在沿槽纹长度至少70%的部分上波纹的大小和形状没有明显改变。 Thus, the term "regular" means that the corrugation (or flute) pattern comprises troughs and ridges with each pair (comprising an adjacent trough and ridge) repeating, at least 70% along the length of the flutes of the corrugated portion of a size and shape without significant change. 在本文中，术语"基本上"是指，由于用于形成波纹或槽纹片材的工艺或形式的变化而导致的改变，而不是由于介质片材403的柔性这一事实而产生的微小变化。 As used herein, the term "substantially" means that, since the process for forming or changing the form of the corrugated or fluted sheet material that results from changes rather than the fact that minor variations due to the flexibility of the media sheet 403 is generated . 对于重复型式的特征，它不意味着在任何给定的过滤器结构上，需要存在同等数量的波峰和波谷。 For feature a repeating pattern, it does not mean that at any given filter construction, requires the presence of an equal number of ridges and troughs. 介质401可止于，例如，包括波峰和波谷的一对之间，或者部分沿包括波峰和波谷的对。 Medium 401 may stop at, e.g., including peaks and troughs between the pair, or partially along the peaks and troughs includes a pair. (例如，在图19中，以局部图示出的介质401具有八个完整的波峰407a和七个完整的波谷407b)。 (E.g., in Figure 19, illustrating a partially medium 401 has eight complete ridges 407a and seven complete troughs 407b). 另外，相对的槽纹端（波谷和波峰端）可能彼此不同。 Further, the opposite flute ends (ends of the troughs and ridges) may vary from each other. 在末端的这种不同在上述定义中是被忽视的，除非另有说明。 In such a different end of the above definitions it is ignored, unless otherwise indicated. 就是说，槽纹末端的不同被倾向包含在上述定义中。 That is, the end of the groove pattern tends to be included in the definition different from that described above.
[0146] 在本文中，波纹的“弯曲的”波型特征，术语“弯曲的”是指波纹型式，不是由提供给介质的折叠或折纹形状产生，而是每个波峰的顶点407a和每个波谷的底部407b沿半径弯曲而形成。 [0146] As used herein, corrugations "curved" wave pattern wherein, the term "curved" refers to a corrugation pattern that is not generated by a folded or creased shape provided to the media, but rather the apex 407a of each ridge and each 407b of the bottom of a trough is formed along a radius bends. 尽管其他方案是可行的，所述ζ-过滤介质的通常半径为至少0. 25mm，通常不大于3mm。 Although alternatives are possible, a typical radius ζ- filter medium is at least 0. 25mm, typically not more than 3mm. （不弯曲的介质，由上述定义，也可以使用）。 (Unbent medium above definition, can also be used).
[0147] 图19所示的波纹片材403的具体规则的、弯曲波型的其他特征是，在每个波谷和每个相邻波峰之间的大致中点430，沿槽纹407长度的大部分，具有过渡区域，在这里弯曲部分倒置。 Specific rules corrugated sheet 403 shown in [0147] FIG. 19, other features are curved, wave pattern, approximately midway between each trough and each adjacent ridge 430, the large flutes 407 along the length of the portion, a transition region where the curvature portion upside down. 例如，观察图19的背侧或面403a，波谷407b是凹入区域，而波峰407a是凸起区域。 For example, observe FIG backside surface 19 or 403a, trough 407b is a concave region, and ridge 407a is a convex region. 当然，当朝正侧或面40¾观察时，侧面403a的波谷407b形成波峰；而面403a的波峰407a形成波谷。 Of course, when observed 40¾ toward front side or face, the side surface 403a forms a ridge valleys 407b; 403a and the surface of the ridges 407a, forms a trough. （在某些情况，区域430可以是直段，而不是点，弯曲部分在直段430的末端倒置）。 (In some instances, region 430 may be a straight segment, instead of points, at the end of the inverted bent portion of the straight segments 430).
[0148] 图19所示的具体规则的、弯曲波型的波纹片材403的特征是，各个波纹大体上是直的。 Specific rules shown in [0148] FIG 19, characterized in curved, wave pattern corrugated sheet 403, the respective corrugations are generally straight. 在本文中，“直的”表示，在边缘404和409之间长度的至少70% (通常至少80%)， 波峰407a和波谷407b的截面没有显著变化。 As used herein, "straight" means that at least 70% (typically at least 80%) of the length between edges 404 and 409, a cross-sectional ridges 407a and troughs 407b do not change significantly. 术语“直的”结合图19所示的波纹型式，部分区别于波纹介质的锥形槽纹型式，所述锥形槽纹型式披露于W097/40918的图1和公开日为2003年6月12日的PCT公开号W003/47722，上述文献在此被结合入本文。 The term "direct" binding corrugation pattern shown in FIG. 19, the tapered flutes of corrugated media section from the tapered flutes are disclosed in W097 / 40918 of FIG. 1 and Publication date of June 12, 2003 Japanese PCT Publication No. W003 / 47722, which are herein incorporated herein by reference. W097/40918 的图1中的锥形槽纹，例如，可以是弯曲的波形，但不是“规则的”型式，或直槽纹型式，如本文所使用的术语。 The tapered flutes W097 / 40918 FIG, for example, may be a curved waveform, but not a "regular" pattern, or a pattern of straight flutes, as the terms are used herein.
[0149] 参见图19和上文，介质401具有第一和第二相对的边缘408和409。 [0149] Referring to Figure 19 and described above, the media 401 has first and second opposite edges 408 and 409. 当介质401 卷绕并形成介质包，一般边缘409会形成介质包的入口端，而边缘408形成出口端，尽管相反的取向是可行的，如下文结合图M所讨论。 When the media 401 is coiled and formed into a media pack, in general edge 409 will form an inlet end for the media pack and edge 408 an outlet end, although an opposite orientation is possible, as discussed in connection with FIG. M.
[0150] 靠近边缘408，片材403，404彼此密封，例如通过密封剂，在这里是以密封剂边410 的形式，将波纹（槽纹）片材403和表面片材404密封在一起。 [0150] near the edge 408, the sheets 403, 404 sealed to each other by a sealant, for example, here in the form of a sealant bead 410, the corrugated (fluted) sheet 403 and facing sheet 404 are sealed together. 密封边410有时候被称作“单面”密封边，当它被作为密封边应用在波纹片材403和表面片材404之间，以形成单面或介质条401。 Bead 410 is sometimes referred to as "one-sided" bead, when it is applied as a bead between the corrugated sheet 403 and facing sheet 404, to form a single facer or media strip 401. 密封边410密封闭合邻近边缘408的单独槽纹411，禁止空气从其通过。 A sealing bead 410 is closed individual flutes 408 adjacent edge 411, air is prohibited to pass therethrough.
[0151] 靠近边缘409处具有密封剂，在这里是以密封边414的形式。 [0151] near the edge 409 has a sealant, here in the form of a sealing edge 414. 密封边414在靠近边缘409处一般闭合槽纹415，以阻止未经过滤的流体通过。 Sealing edge 414 near the edge 409 generally closes flutes 415 to passage of unfiltered fluid. 在介质401围绕自身卷绕时通常应用密封边414，使波纹片材403向内。 When the media 401 is wound around itself usually applied bead 414, so that the corrugated sheet 403 inwardly. 因此，密封边414会在表面片材404的背侧417 和波纹片材403的侧面418之间形成密封。 Thus, bead 414 will form a seal between the backside surface 418 at the side 404 of the sheet 417 and the corrugated sheet 403. 当它作为条401卷绕成卷绕的介质包时，密封边414有时候被称作“卷绕密封边”。 When it is wound into a coiled media pack as Article 401, bead 414 is sometimes referred to as "winding bead." 如果介质401被切成条并且层叠，而不是卷绕，密封边414就是“层叠密封边"。 If the media 401 were cut into strips and stacked, instead of coiled, bead 414 would be a "stacking bead."
[0152] 在某些应用中，波纹片材403还在沿槽纹长度的不同点连接至表面片材4，如线404a所示。 [0152] In some applications, the corrugated sheet 403 is also different points along the length of the land and groove connection to a facing sheet 4, as shown in line 404a.
[0153] 参见图19，一旦介质401整合入介质包，例如，通过卷绕或层叠，它可以操作如下。 [0153] Referring to Figure 19, once the media 401 is incorporated into a media pack, for example, by coiling or stacking, it can operate as follows. 首先，沿箭头412方向的空气进入靠近端部409的开口槽纹411。 First, air in the direction of arrow 412 into the open flutes 411 adjacent end 409. 由于在端部408处由密封边410闭合，空气会沿箭头413所示方向通过介质。 Since 410 is closed by a sealing edge at the end portion 408 in the direction indicated by the arrow 413 the air will be the medium. 然后通过靠近介质包的端部408，槽纹415的开口端41¾排出介质包。 Then 408, the open end of the flutes of the media pack 415 is discharged through 41¾ near the end of the media pack. 当然，操作可以按相反方向的空气流动进行，如结合图24 所讨论的。 Of course, the operation may be performed in an air flow in the opposite direction, as discussed in conjunction with FIG. 24. 关键是在通常的空气过滤器应用中，在介质包的一端或面，未经过滤的空气流进入，并且在相对端或面，已过滤的空气流流出，而没有未经过滤的空气流通过介质包或在面之间。 The key is in the normal air filter applications, at one end or face of the media pack unfiltered air flow into, and at the opposite end or face the filtered air flow coming out, and no unfiltered air flow through the media pack or between the faces.
[0154] 对于图19所示的具体结构，平行的波纹7a，7b大体上沿整个介质是直的，从边缘708到边缘709。 [0154] For the particular configuration shown in FIG. 19, the parallel corrugations 7a, 7b are generally straight along the entire media, from edge 708 to edge 709. 直槽纹或波纹可以在选定位置，尤其在端部变形或折叠。 Straight flutes or corrugations can be deformed, especially at the end portion or folded position selected. 在槽纹末端闭合的改进一般在上述“规则的”，“弯曲的”和“波型”的定义中被忽略。 In the closed end flute improvements generally be ignored, "curved" and "wave pattern" in the above definition of "rules" in the.
[0155] 不采用直的、规则的弯曲波型的波纹（槽纹）形状的Z-过滤器结构是已知的。 [0155] does not utilize straight, regular curved wave pattern corrugation (flute) Z- shape of the filter structure is known. 例如，Yamada等在US 5，562，825中示出了采用有些半圆形（截面）入口槽纹靠近窄V-形(具有弯曲侧面）出口槽纹的波纹型式（参见5，562，825的图1和3)。 For example, Yamada et al in US 5,562,825 use is shown somewhat semicircular (cross section) inlet flutes near the narrow V- shaped (with curved sides) exit flutes of corrugation (see 5,562,825 1 and FIG. 3). Matsumoto等在US 5，049，326中示出了圆形（截面）或管状槽纹，它通过一个具有半管的片材连接另一个具有半管的片材形成，在所得到的平行的直槽纹间具有扁平区域，参见Matsumoto' 326 的图2。 Matsumoto et al US 5,049,326 shows a circular shape (cross-section) or tubular flutes, another sheet having half tubes is formed which is connected via a sheet having half tubes, straight in parallel to the resulting with flat regions between the flutes, see Matsumoto '326 of FIG. Ishii等在US 4，925，561(图1)中示出了折叠成具有矩形截面的槽纹，其中槽纹沿其长度逐渐收缩。 Ishii et al in US 4,925,561 (FIG. 1) shows flutes folded to have a rectangular cross section, wherein the flutes tapers along its length. 在W097/40918(图1)中，示出了具有弯曲波型（从相邻的弯曲凸起或凹入的槽）的槽纹或平行波纹，但其沿长度方向逐渐收缩（并因此不是直的）。 In W097 / 40918 (FIG. 1), shows a curved, wave patterns (from convex or concave curved groove adjacent to) the flutes or parallel corrugations, but which tapers in the longitudinal direction (and thus are not straight of). 另外，在W097/40918中示出了具有弯曲波型的槽纹，但具有不同尺寸的波峰和波谷。 Further, in W097 / 40918 shows flutes have curved wave patterns, but with different sized ridges and troughs.
[0156] 一般，过滤介质是相当柔性的材料，通常是无纺纤维材料（纤维素纤维，合成纤维或两者），通常其内包含树脂，有时用其他材料处理。 [0156] In general, the filter media is a relatively flexible material, typically a non-woven fibrous material (of cellulose fibers, synthetic fibers or both) typically contains a resin therein, sometimes treated with additional materials. 因此，它可以适合或设置成不同波纹型式，而没有不可接受的介质损坏。 Thus, it may be adapted or configured into the various corrugated patterns, without unacceptable media damage. 另外，它便于卷绕或者以其他方式构造以便使用，同样没有不可接受的介质损坏。 Further, it facilitates wound or otherwise configured for use, again without unacceptable media damage of. 当然，它必须具备在使用期间保持所需要的波纹结构的性质。 Of course, it must have properties to maintain the required corrugated configuration, during use.
[0157] 在波纹形成过程中，使介质发生非弹性变形。 [0157] In the corrugation process, the media of the non-elastic deformation occurs. 这防止了介质恢复至其原始形状。 This prevents the medium was returned to its original shape. 不过，一旦解除张力，槽纹或波纹会倾向于反弹，仅仅恢复部分已发生的拉伸和弯曲。 However, once the tension is released the flute or corrugations will tend to spring back, only portions of the stretch and bending recovery has occurred. 表面片材有时连接至槽纹片材，以阻止波纹片材的这种反弹。 Facing sheet is sometimes connected to the fluted sheet, to inhibit this spring back in the corrugated sheet.
[0158] 另外，通常，介质包括树脂。 [0158] Further, generally, the medium comprises a resin. 在波纹成形过程中，介质可被加热到高于树脂的玻璃转变点。 During the corrugation process, the media can be heated to above the glass transition point of the resin. 当树脂随后冷却时，有助于保持槽纹形状。 When the resin then cools, it helps to maintain the fluted shapes.
[0159] 波纹片材403，表面片材404或这两者的介质，可以在其单侧或两侧具有细纤维材料，例如，根据US 6，673，136，在此被结合入本文。 [0159] the corrugated sheet 403, facing sheet 404 or both media, may have a fine fiber material on one or both sides thereof, for example, according to US 6,673,136, hereby incorporated herein by reference.
[0160] Z-过滤器结构的一个问题涉及闭合单个槽纹端。 [0160] One problem Z- filter constructions relates to closing of the individual flute ends. 通常，提供密封剂或黏合剂，来实现闭合。 Typically, a sealant or adhesive, to achieve closure. 从上述讨论可见，在通常的ζ-过滤介质中，特别是使用直槽纹而非锥形槽纹的介质，需要在上游端和下游端具有大的密封剂表面积（和体积）。 It is seen from the above discussion, in the conventional ζ- filter media, in particular using a straight flutes as opposed to tapered flutes of the medium, having a large sealant surface areas (and volume) at both the upstream and downstream ends. 在这些部位的高质量密封对于所形成介质结构的正常工作来说是关键的。 In these areas a high quality seal to proper operation of the media structure that is formed is critical. 高密封剂体积和面积产生了与之相关的问题。 The high sealant volume and area, creates issues associated therewith.
[0161] 现参见图20，其中示出了ζ-过滤介质结构440，它采用规则的、弯曲波型的波纹片材443，和表面（在这里是非波纹状）片材444。 [0161] Referring now to FIG. 20, which shows a ζ- filter media structure 440, which uses regular, curved, wave pattern corrugated sheet 443, and the surface (where non-corrugated) sheet 444. 点450和451之间的距离Dl在给定波纹状槽纹453下面的区域452形成了表面介质444的延伸部分。 The distance between the point Dl 450 and 451 in the region 453 below a given corrugated flute 452 forming a extension of facing media 444. 波纹状槽纹453的弧形介质的长度D2，在相同的距离Dl上当然是大于D1，这是由于波纹状槽纹453的形状。 Corrugated flute length D2 of the arcuate media 453, over the same distance Dl is of course larger than D1, due to the shape of the corrugated flute 453. 对于用于槽纹过滤器应用中的通常规则形状的介质，点450和451之间介质453的线性长度D2 —般是Dl的至少1.2倍。 For a typical regular shaped media used in fluted filter applications, the media 453 between points 450 and 451 of the linear length D2 - is generally of at least 1.2 times Dl. 通常，D2是Dl的1.2-2.0倍的范围，包括端点值。 Typically, D2 would be the range of 1.2 to 2.0 times Dl, inclusive. 空气过滤器的一种特别常见的结构具有这样的结构，其中D2为大约1. 25-1. 35XD1。 An air filter is particularly convenient arrangement has a configuration in which D2 is about 1. 25-1. 35XD1. 例如，所述介质已被商业应用在DonaldsonPowercore™ Z-过滤器结构上。 For example, the media have been used commercially in DonaldsonPowercore ™ Z- filter constructions. 在这里，比率D2/D1有时候被表征为波纹（槽纹）介质的槽纹/平面比或介质拉伸性。 Herein the ratio D2 / D1 will sometimes be characterized as the flute corrugated (fluted) medium / flat ratio or media draw.
[0162] 在波纹纸板行业中，已定义了各种标准的槽纹。 [0162] In the corrugated cardboard industry, various standards have been defined flutes. 例如，标准E槽纹，标准X槽纹，标准B槽纹，标准C槽纹和标准A槽纹。 For example, the standard E flute, standard X flute, standard B flute, standard C flute and standard A flute. 所附的附图21，结合下面的表A提供了这些槽纹的定义。 21 of the accompanying drawings, in conjunction with Table A below provides definitions of these flutes.
[0163] 本发明的受让人，唐纳森公司（DCI)，已将标准A和标准B槽纹的变形应用在多种ζ-过滤器结构上。 [0163] The assignee of the present invention, Donaldson Company, Inc. (the DCI), deformation of the standard A and standard B flutes, in a variety of applications ζ- filter structure. 这些槽纹也在表A和图21中进行定义。 These flutes are also shown in Table A and Fig. 21 is defined.
[0164] 当然，来自波纹状盒子行业的其他标准的槽纹定义是已知的。 [0164] Of course, other criteria from the corrugated box industry are known in the flutes defined.
[0165] 一般，来自波纹状盒子行业的标准槽纹结构可用于定义波纹状介质的波纹形状或近似波纹形状。 [0165] In general, standard flute configurations from the corrugated box industry can be used to define corrugation shapes or approximate corrugation-like shape medium. 上述DCI A槽纹和DCI B槽纹，与波纹行业标准A和标准B槽纹之间的比较，表明了某些常见的变化。 Above the DCI A flute and the DCI B flute, and the comparison between the A and standard B flute corrugated industry standards, indicate some convenient variations. 还可以使用多种其他槽纹尺寸和形状，具有本文所述的结构。 You may also be used more other flute sizes and shapes, having structures described herein.
2.采用槽纹介质制造卷绕的介质结构，概述。 2. The use of media production coiled media construction flutes, overview.
[0166] 在图22中，示出了用于制成对应图19所示条401的介质条的制造工艺的一个示例。 [0166] In FIG 22, it illustrates an example of a process for manufacturing a strip made as shown in FIG. 19 corresponding to the dielectric strip 401. 一般，表面片材464和具有槽纹468的槽纹（波纹）片材466结合在一起，以形成介质网469，在其间470处有黏合剂密封边。 In general, facing sheet 464 and the fluted (corrugated) sheet 468 having flutes 466 bonded together to form a media web 469, with a sealing adhesive at the edge 470 therebetween. 黏合剂密封边470会形成图19所示的单面密封边410。 Adhesive bead 470 will form a single facer bead 410 shown in FIG. 19. 在工位471处进行可选的针刺加工，以形成位于网中间的中央针刺部分472。 An optional darting process occurs at station 471 to form center darted section in the middle of the web 472. ζ-过滤介质或Z-介质条474可以沿密封边470在475处切割或割开，以形成ζ_过滤介质474的两部分476，477，各自具有边缘，有密封剂条（单面密封边）在波纹和表面片材之间延伸。 ζ- Z- filter media or media strip 474 can be cut along seal 470 at the edge 475 or the cut, the two portions 476, 477 and 474 to form ζ_ filter media, each having an edge with a strip of sealant (single facer bead ) extending between the corrugating and facing sheet. 当然，如果采用可选的针刺加工，具有密封剂条（单面密封边）的边缘还具有一组在该位置针刺的槽纹。 Of course, the edge if the optional darting process, with a strip of sealant (single facer bead) would also have a set of flutes darted at this location.
[0167] 另外，如果使用连接密封边或其他固定连接40½，见图19，它们可以在片材464， 466结合在一起时形成。 [0167] Further, if the sealing edge or other connector fixedly connected 40½, Figure 19, they may be incorporated in the sheet 464, 466 together is formed.
[0168] 用于进行图22所示加工的技术披露于公开日为2004年1月22日的PCTW004/007054,在此被结合入本文。 Technology [0168] for performing processing shown in FIG. 22 is disclosed in Japanese Publication of PCTW004 / 007054 January 22, 2004, and hereby incorporated herein by reference.
[0169] 仍然参见图22，在ζ-过滤介质474通过针刺工位471并最终在475处割开之前， 它必须成型。 [0169] Still referring to FIG. 22, the filter media in ζ- 474,471 and 475 before finally cut, it must be formed by needling station. 在图22所示的示意图中，这通过使介质片材492通过一对波纹辊494，495来实现。 In the schematic shown in FIG. 22, by which the sheet of the medium 492 is achieved through a pair of corrugation rollers 494,495. 在图22所示的示意图中，介质片材492从辊496展开，围绕张力辊498卷绕，然后通过波纹辊494，495之间的辊隙或咬合部分502。 In the schematic shown in FIG. 22, the sheet of media 492 is unwound from the roll 496, wound around tension rollers 498, and then through the nip between the corrugation rollers 494,495 or bite 502. 波纹辊494，495具有齿504，在扁平片材492通过辊隙502之后，会产生大体上需要形状的波纹。 Corrugation rollers 494, 495 have teeth 504, after the flat sheet 492 passes through the nip 502, it will produce a substantially ripple desired shape. 在通过辊隙502之后，片材492成为波纹状通过机器方向，并且在466处标记为波纹片材。 After passing through the nip 502, the sheet 492 becomes corrugated by a machine direction, and at 466 as the corrugated sheet. 然后将波纹片材466固定至表面片材464。 The corrugated sheet 466 is then secured to facing sheet 464. (在某些情况，波纹加工可能涉及对介质进行加热）。 (In some cases, the corrugation process may involve heating the media).
[0170] 仍然参见图22，所述加工还示出了表面片材464被送至针刺加工位置471。 [0170] Still referring to FIG. 22, the process also shows the facing sheet 464 being routed to the darting process location 471. 所示的表面片材464在卷506上保存，然后被导向波纹片材466，以形成Z-介质474。 Surface of the sheet 464 shown on the volume 506 stored, is then directed to the corrugated sheet 466, 474 to form the Z- media. 波纹片材466和表面片材464通过黏合剂或通过其他方式固定在一起（例如通过声波焊接）。 The corrugated sheet 466 and facing sheet 464 by an adhesive or otherwise secured together (e.g. by sonic welding).
[0171] 参见图22，示出了黏合剂线470用于将波纹片材466和表面片材464固定在一起， 作为密封边。 [0171] Referring to Figure 22, adhesive line 470 is shown used to secure corrugated sheet 466 and facing sheet 464 together, as the sealant bead. 另外，用于形成表面密封边的密封剂边可应用在所示470a处。 Further, the sealant for forming the side surface of the sealing edge can be applied as shown at 470a. 如果密封剂涂在470a处，希望波纹辊495上有间隙，并可能同时在波纹辊494，495上有间隙，以容纳密封边470a。 If the sealant is applied at 470a, corrugated desired gap roller 495, and may also have a gap in the corrugation rollers 494,495, to accommodate the bead 470a.
[0172] 波纹介质所具有的波纹类型是可以选择的，并且通过波纹辊494,495的波纹或波纹齿规定。 [0172] the corrugated medium has corrugations type can be selected, and dictated by the corrugation or corrugation teeth of the corrugation rollers 494,495. 一种优选的波纹型式是规则的弯曲波型波纹的直槽纹，如上文所定义。 One preferred corrugation pattern will be a regular curved wave pattern of straight flutes of the corrugated rules, as defined above. 所使用的通常规则的弯曲波型为，其中上文所定义的波纹型式上的距离D2是上文所定义的距离Dl的至少1.2倍。 Typical regular curved wave pattern is used in which the distance D2, as defined above, in a corrugated pattern is at least 1.2 times the distance Dl as defined above in. 在优选应用中，通常D2 = 1.25-1. 35 XDl。 In a preferred application, typically D2 = 1.25-1. 35 XDl. 在某些情况，所述技术可应用于非“规则的”弯曲波型，包括例如，不使用直槽纹的波型。 In some cases, the techniques may be applied to non "regular" curved wave patterns, including, for example, do not use straight flutes wave.
[0173] 如上所述，图22所示的加工可用于形成中央针刺部分472。 [0173] As described above, the processing shown in FIG. 22 may be used to form center darted section 472. 图23以剖视图形式示出了在针刺和割开之后的一个槽纹468。 23 illustrates in cross-section showing one of the flutes 468 after needling and cut open.
[0174] 可以看到，折叠结构518形成了针刺槽纹520，它具有四个折纹512a，512b, 521c, 512d。 [0174] It can be seen folded structures 518 are formed darted flute 520 with four creases which 512a, 512b, 521c, 512d. 折叠结构518包括固定至表面片材464的扁平第一层或部分522。 Folding structure 518 comprises a flat sheet secured to the surface 464 of the first layer or portion 522. 所示的第二层或部分5M压抵第一层或部分522。 5M second layer or portion shown pressed against the first layer or portion 522. 第二层或部分5M优选通过折叠第一层或部分522的相对外端526，527而形成。 5M second layer or portion preferably by folding the first layer or portion 522 is formed opposite outer ends 526,527.
