PROCESS AND APPARATUS FOR MAKING A POSTCARD

Abstract: A first strip (50) is supplied continuously and comprises a card layer (51) and a first layer of adhesive (52). A second strip (54) is also supplied continuously and comprises a transparent sheet (55) and a second layer of adhesive (56) on it. A protective sheet (57) is supplied continuously between the first and second strips (50, 54). The first and second strips are laminated together, with one edge bonded together by the first and second layers of adhesive. The protective sheet is laminated between the remaining, main parts of the layers of adhesive. This composite strip is cut transversely to form individual postcards (100). In use, the protective sheet can be removed, to enable photographs and other articles to be laminated between the card and the transparent sheet.

Description: This invention relates to a process and apparatus for making a postcard for use in mailing sheet-form articles. There have been earlier proposals for mailing photographs through the mail and for mounting photographs. However, generally these earlier proposals have had complex constructions, which would be complicated, difficult and costly to manufacture. Thus, in U.S. - A - 3,304,641 (Gonczy), there is disclosed a picture postcard having numerous removable portions, which when removed reveal areas of adhesive. The stated intention is to enable different sized photographs to be stuck to the card. The provision of numerous separately removable portions, requires a complex pattern of separation lines to be cut into the top of the card structure. Such a card would be difficult to manufacture. Further, it leaves the top surface of any article stuck to it exposed. In U.S. - A - 3,329,333, (Ormond) there is disclosed a postcard, that is not intended for mailing articles, but simply to enable selected portions of a message to be concealed. To this end, it provides a cut out portion in one sheet, and a notch forming a tab. These features again would create considerable production difficulties, and prevent the postcard being produced readily in any continuous form. An article for postal conveyance is disclosed in U.S. - A - 3,899,127 (Melander). Here a somewhat complex structure is provided. A transparent envelope cover is stuck to a card around three edges thereof, which immediately creates the problem of forming an adhesive layer around just those three edges, rather than all over the two components of the card. Thus, this structure is not suited to continuous mass production. There is disclosed an apertured mailing card and method of using it in U.S. - A - 4,008,852 (Davis). This structure is complex. The card has two card sections which are folded together. An adhesive portion is provided along the edge of one section, so that the two sections can be secured in the folded configuration. One card section is provided with an adhesive area and a removable backing sheet for a photograph, whilst the other card section is provided with an opening for viewing the photograph. The opening is covered by a transparent sheet. It will thus be apparent that this card includes numerous components of different proportions, and it is not at all clear how such a construction could be economically produced. A photographic mailing postcard is disclosed in U.S. - A - 4,237,633 (Murrell). Here, a complex construction is disclosed. The card includes numerous cuts, score lines and folds. It has six separate patches of adhesive, which apparently use two or three different sorts of adhesive. Thus, mention is made of both a moistenable type adhesive and a contact adhesive. To construct such a card with all the cuts, score lines etc. and different types of adhesive in different places would be extremely complex. It would require a lengthy and complicated production process. U.S. - A - 4,249,328 (Plumadore) discloses an electrophotographic slide, whilst U.S. - A - 4,378,647 (Stancato) discloses a photographic album. In both these proposals, the constructions are again quite complex. In the Plumadore proposal, each slide includes a pair of panels hingedly connected together. Each panel defines a window, and is coated with an adhesive. The film section is bonded to one panel, whilst a transparent protective film is bonded to the other panel. Thus, the structure is quite complicated, and not readily produced in a simple, economical fashion. The Stancato patent discloses a photograph album, which is intended to give the effect that each individual page has a photograph mounted on it and then the pages bound into an album. As such, the construction requires numerous fixed and movable components of different dimensions and orientation. This again would require a complex and expensive production technique. The technical problem is to produce postcards which each have uniform properties or dimensions in one direction, across their width as a continuous strip. All of the main components are assembled together in strip form, and, at the end of the production process, this strip is cut to form the individual postcards. Thus, in accordance with the present invention, there is provided a process for making a postcard, for use in mailing sheet-form articles, the process comprising the steps of: continuously supplying a first elongate sheet-member strip including a first layer of adhesive on one side thereof; continuously supplying a second, elongate strip of a transparent sheet including a second layer of generally transparent adhesive on one side thereof; continuously mounting a third, elongate strip of a protective sheet between said first and second strips so as to leave opposed edge regions of the first and second adhesive layers bonded to one another, with the remainder of the first and second adhesive layers separated by the protective sheet thereby forming a fourth, composite strip; and cutting the fourth, composite strip transversely to form individual postcards. The process of the present invention thus enables the various components of the postcard to be assembled together as continuous strips. This produces a composite strip having a section corresponding to that of the finished postcard. This composite strip can then simply be cut transversely, to form the individual postcards. In a preferred form of the invention, the first elongate strip is supplied as said first elongate strip bearing said first layer of adhesive and an intermediate protective sheet having the same dimensions as the first elongate strip and covering the first layer of adhesive, and the intermediate protective sheet is removed prior to the step of continuously mounting the said third elongate strip. If necessary, the bonded edges of the sheet member and transparent sheets can be trimmed, to give a flush edge. One then has the composite strip of appropriate section, which can be cut transversely to form the finished cards. As all the operations can be carried out in a continuous manner and as the forming operations required are relatively simple, the postcards can be produced in large quantity economically. There is no need to subject each individual postcard to separate and complex forming operations. In accordance with another aspect of the present invention, there is provided an apparatus, for use in producing postcards, the apparatus comprising: a strip path; means for moving an elongate strip along the strip path; a first supply unit for supplying a first, elongate, sheet-form member strip to the strip path; a second supply unit for supplying a second, elongate strip of a transparent sheet to the strip path; a laminating station, downstream from the first and second supply units, for laminating together the first and second elongate strips to form a composite strip; a trimming section downstream from the laminating station for trimming the composite strip; and a cutting section downstream from the trimming section for cutting the composite strip into individual postcards. The means for moving the elongate strip can comprise driven rollers along the strip path. For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a side view of an apparatus in accordance with the present invention, for carrying out the process of the present invention; Figure 2 shows a section along the line 2-2 of Figure 1; Figure 3 shows a section along the line 3-3 of Figure 1; Figure 4 shows a section along the line 4-4 of Figure 1; Figure 5 shows a section along the line 5-5 of Figure 1; Figure 6 shows a section along the line 6-6 of Figure 1; Figure 7 shows a cross-section, comparable to that of Figure 6, of a variant of the process; Figure 8 shows a perspective view of a postcard produced by the process of the present invention; and Figure 9 shows a perspective view of the postcard of Figure 8, including a photograph. In the drawings, the sections of Figures 2-6 are all taken in the same direction. The description relates to a postcard structure, in which the height of the postcard extends across the strip and the width extends along the strip. For consistency, the term "height" is used throughout to refer to both the height of the postcard and dimensions across the strip. With reference to Figure 1, there is shown an apparatus, generally denoted by the reference 1. The apparatus 1 includes a card stock supply unit 2 and a transparent sheet stock supply unit 4. These units 2, 4 have respective cores rotatably mounted on them on which a roll of card or transparent sheet stock is wound. It also includes four rewind units 6, 8, 10 and 12. Each of the rewind units 6, 8, 10 and 12 similarly has a core rotatably wound on it for rewinding part of the strip, as detailed below. Also, to guide the card stock and other strips, there are numerous transverse rollers 14. These rollers 14 guide the card stock in known manner, and will not be described in greater detail. The rollers 14 form part of a strip path 15 and may be driven to move material through the apparatus. The card stock unit 2 bears a roll of an elongate strip of card stock having the section shown in Figure 2, and denoted by the reference 50. This section 50 need simply be slightly greater than the height of a finished card to allow for trimming. The card stock 50 includes the actual card strip 51, which provides the sheet-form member. The card strip 51 is shown uppermost in the section of Figure 2, and carries on its lower surface a first layer of adhesive 52. An intermediate protective or backing sheet 53 is provided against the layer of adhesive 52 to protect it. This protective strip 53 can, for example, be silicone coated paper. As shown in the section of Figure 2, all the components of the card stock 50 are of the same width. The card stock 50 is caused to travel over rollers 14 to a print station 16. At this print station 16, the upper or exposed side of the card strip 51 is printed, to provide desired information on what will become the reverse side of the finished postcards. Thus, in known manner, it can be printed with an outline or box indicating a place for a postage stamp, an indication of where the recipient's address should be placed, and an indication where a message should be placed. It could also include material indicating the source of the postcard, trade marks and other information. The card stock 50, after leaving the print station 16, passes to a dryer 18. The dryer 18, like the print station 16 is shown schematically. Here, the ink on the upper side of the card stock 50 is dried. The next major operation is to combine the card stock 50 with a transparent sheet stock. For this, it is necessary to reverse the card stock 50. This is achieved by a turn bar unit 20, which is shown schematically in Figure 1. The turn bar unit 20 reverses the card stock 50, so that the protective sheet 53 is uppermost, and the reversed configuration is shown in Figure 3. Then, the intermediate protective sheet 53 is removed from the card stock 50 across its full width. This separation takes place at 22. The protective sheet 53 is pulled vertically upwards and wound on a protective sheet rewind core of the intermediate protective sheet rewind unit 6. The unit 6 is driven, so as to maintain sufficient tension in the protective sheet 53, to cause it to separate from the layer of adhesive 52. This leaves a modified card stock strip 50a, comprising the card strip 51 with the first adhesive layer 52, to travel to the next step of the process. The card strip 51 and adhesive layer 52 travel to a laminating station 24. Simultaneously, a strip of transparent sheet stock 54 is supplied to the laminating station 24. This transparent sheet stock 54 is supplied as a roll on a core on the transparent sheet stock supply unit 4. The transparent sheet stock 54, as detailed below has a height greater than the height of the transparent sheet in finished postcards plus the height of a tab. The transparent sheet stock 54 comprises, as shown in Figure 4, a strip 55 of a transparent material, a second adhesive layer 56, and a protective sheet 57. The transparent sheet stock 54 is supplied with the protective sheet 57 already slit along one side, as indicated at 58. This slit 58 separates the protective sheet 57 into a main part 59 and an edge strip 60. The slit 58 enables the edge strip 60 to be separated immediately. This edge strip 60 is removed as indicated, and disposed of by a vacuum waste removal system 26. Figure 4 shows the section immediately after the edge strip 60 is lifted from the second adhesive layer 56. The modified transparent sheet stock, without this edge strip 60 is denoted by the reference 54a. It is to be noted that, due to the location of the section line 4-4, the protective sheet 57 is on the top in Figure 4. As the modified transparent sheet stock 54a travels around the roller 4, the protective sheet 57 is turned to the underside. The edge strip 60 is shown, schematically, as travelling around a roller 29 to the vacuum waste removal system 26. The laminating station 24 includes rollers, which laminate or press the modified card stock 50a against the modified transparent sheet stock 54a. The main part 59 of the protective sheet maintains the first and second layers of adhesive 52, 56 largely separated. However, edge portions of the adhesive layers, denoted by the references 52a, 56a, are pressed together. This is shown at the left-hand side of Figure 5. It results in a composite strip denoted by the reference 62. This composite strip 62 has a uniform section at its center, comprising five layers, namely the card strip 51, the first adhesive layer 52, the protective sheet 57, the second adhesive layer 56 and the transparent strip 55. These five layers are all generally level with one another at the right-hand edge. The composite strip 62 has the section shown in Figure 5, but prior to removal of the edge trim 66 detailed below. As a right-hand edge of the card strip 51 is discarded, it need not extend to the right so as to be flush with the edge of the protective sheet 57. The composite strip 62 then travels to a first trim station 28. The trim station 28, like later trim stations, is shown schematically as including a circular cutting blade on one side and a support roller on the other side. At this first trim station 28, the transparent strip 55 is cut through, together with the adhesive layer 56, to the protective sheet 57. This cut is marked at 64 in Figure 5. This separates a transparent edge trim 66, which comprises an edge of the transparent strip 55 together with a corresponding part of the second adhesive layer 56. This transparent edge trim 66 is removed and wound on the transparent trim rewind unit 8. This results in a first, modified composite strip 62a, which has the section shown in Figure 5, without the edge trim 66. This modified composite strip 62a passes to a second trim station 30. At this second trim station 30, the card strip 51 is cut through, as indicated at 68 in Figure 6. The cut 68 extends through to the protective sheet 57, and separates a card edge trim 70 comprising part of the card strip 51 and part of the first adhesive layer 52. This card edge trim 70 is then separated, as indicated in Figure 6, and wound on a core on the card stock trim rewind unit 10. This results in a second, modified composite strip 62b, as shown in the section of Figure 6. Here, an edge of the protective sheet 57 is now exposed as a tab 61. This modified composite strip 62b then passes to a third trim station 32. As indicated in Figures 5 and 6, after the card stock 50 and transparent sheet stock 54 have been laminated, the edges of the various components need not be necessarily flush, and in general will not be flush. The third trim station 32 is provided for trimming this left-hand edge of the composite strip 62b, to ensure that the various layers are flush at the left-hand edge of the strip 62b. This final edge trim at the station 32 is indicated by dotted lines 72 in Figure 6. This results in the removal of a composite edge trim 74, which is removed and wound on a core on the composite edge trim rewind unit 12. This results in a third and final, modified composite strip 62c, which has the profile required for the final postcard. This composite strip 62c passes to a cutting unit 34, which can be conventional. The cutting unit 34 includes an anvil 35 and a cutting or sheeter blade 36, both shown schematically. The sheeter blade 36 cuts the strip to the required length, to form finished postcards 100. The cutting unit 34 is synchronized with the printing station 16, to ensure proper alignment of the printed matter on the postcards 100. The finished postcards 100 are then transported by a conveyor 38 to a stacker 40. The stacker 40 stacks the postcards 100 for packaging, delivery etc. Figures 8 and 9 show the finished postcard 100. Here, the various components of the postcard 100 are given references corresponding to those used for the strips in the process, but greater by 100. Thus, the postcard 100 has a main card, or sheet-form part 151, and a transparent sheet 155. The card 151 bears a first layer of adhesive 152, whilst the transparent sheet 155 bears a corresponding second layer of adhesive 156. These adhesive layers 152, 156 contact one another along an edge strip 149. Otherwise, the protective strip 157 maintains the adhesive layers 152, 156 separate. The protective sheet 157 includes a tab 161. As indicated in Figure 8, the top of the protective sheet 157 is preferably pre-printed with instructions 167. These instructions 167 need not be synchronized with cutting unit 34, as the protective sheet 157 is discarded. Instead, the instructions can be repeated at regular intervals, e.g. at intervals less than one half the width of the postcard 100, to ensure that each sheet 157 contains at least one complete set of instructions. With regard to preferred materials, the card 151 can be made from cardboard sold under the name Kromecote (Registered Trade Mark), which has 12 point thickness. One side of the card is matte and the other side is shiny. The matte side is the side that is printed at the print station 16 with information regarding address etc. The glossy side is coated with the first layer of adhesive 152. Preferably, this side is first coated or printed with a grey colour, before the first layer of adhesive 152 is applied. This first layer of adhesive is preferably a pressure-sensitive adhesive, and need not be transparent. The transparent sheet 155 is, preferably, a laminate formed from polyester having 2 mil. thickness. The second adhesive layer 156 needs to be transparent, or largely transparent, in order that the photograph or other article can be viewed through it. This second adhesive layer 156 can also be a pressure-sensitive adhesive. It could, for example, be tinted with some colour, which may be deisrable for some purposes. The protective sheet 157 is formed from paper stock having a weight of 65 pounds/ream. It is coated on both sides with silicone. The instructions 167 are printed onto the sheet 157, before coating with the silicone. The silicone is also transparent, to permit the instructions 167 to be read through the transparent sheet 155. The bottom silicone coating 163 and a top silicone coating 165 should preferably be of different weights. Preferably, the bottom silicone layer 163 should cause the protective sheet 157 to release readily from the first layer of adhesive 152, whilst the second silicone layer 165 should require a positive peel action, to separate the sheet 157 from the transparent sheet 155. This should ensure that the postcard 100 is used correctly. With regard to preferred dimensions, it is suggested that the components of the postcard 100 be dimensioned to accept standard sized photographs. At the present time, a standard sized photograph has the dimensions of 4" x 6". Accordingly, all the components have a width of 6". The card 151 and transparent sheet 155 have a height of 4¼", as do their adhesive layers 152, 156. The edge strip 160 has a width of approximately ¼", depending on the trimming operation, so that the usable area of the card 100 is 4" x 6". Since the insertion of a photograph will distort the transparent sheet 155, it could be cut with a slightly increased height, to allow for such distortion. Thus, the lower edge of the transparent sheet 155 could be 1/32" below the bottom edge of the card 151. Then, after insertion of a photograph as detailed below, the lower edges of the card 151 and transparent sheet 155 will be flush. In Figure 8, the protective sheet 157 is shown schematically separate from both the adhesive layers 152, 156; in practice, the tab 161 is used to lift the protective sheet 157 together with the transparent sheet 155. This then exposes the first adhesive layer 152, except along the edge strip 149. A photograph, indicated at 170 in Figure 9, is then mounted on the first adhesive layer. Figure 9 shows a photograph smaller than the adhesive layers, to leave an exposed border of adhesive around the photograph 170. The protective sheet 157 is then removed, and the transparent sheet 155 replaced. This causes the second adhesive layer 156 to contact and adhere to the exposed border of the first adhesive layer 152 and to the photograph 170. Figure 9 shows the transparent sheet 155 as it is being replaced. This results in a laminated structure, which should protect the photograph 170 during handling in the postal system etc. The process described above with reference to Figures 1-6 is based on a process that produces a composite strip having a section equal to that of a single postcard. Figure 7 shows a variant embodiment, in which a composite strip 80 is produced. This composite strip 80 includes a card strip 81, bearing a first layer of adhesive 82. A transparent strip 85 has a second adhesive layer 86 extending across it. Two separate protective sheet portions 87, 88 are provided, separating the adhesive layers 82, 86 on either side. This leaves a central region 89, in which the adhesive layers 82, 86 are bonded to one another. The protective sheets 87, 88 have respective tabs 90, 91. The components of this composite strip 80 can be formed similarly to the technique detailed above. Thus, a central part of a protective strip would be removed, to form the two separate protective sheets 87, 88. The transparent sheet 85 with the protective sheets would then be laminated with the card strip 81 bearing the first adhesive layer 82. Both edges of the transparent strip 85 and the card strip 81 would then be cut and removed, to form the tabs 90, 91. It will then be appreciated that this composite strip 80 is comparable to two of the composite strips 62c placed back to back. Accordingly, as indicated at 92, the composite strip 80 is cut in half, to form separate strips, each of which needs simply be cut transversely to form the individual postcards.
