Notice of Pre-AIA  or AIA  Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Specification
The disclosure is objected to because of the following informalities:
[0049] “pneumatic cylinder 15” should read “pneumatic cylinder 16”
[0052] after “According to Fig. 1e, the second feed unit” add –50--
[0058] “coupling element 10” should read “coupling unit 10” for consistency in terminology; otherwise, it is suggested to indicate coupling element/unit in the first instance in order to establish that the terms are synonymous
[0065] “first guide element 30” needs review whether it should read “first feed unit 30”
[0068] “lower clamp part” should read “lower clamping part 88” for consistency in terminology
Appropriate correction is required.
Claim Objections
Claim(s) 31 is/are objected to because of the following informalities:
Claim 31 is missing a period
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b)  CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
Claim(s) 22 is/are rejected under U.S.C. 112(b).
Claim 22 recites the limitation the common drive in Line 1.  There is insufficient antecedent basis for this limitation in the claim.
As such, it is unclear what the term “the common drive” is referring to.  Claim 22 depends on Claim 20, which established that each of the slides are individually “motor-driven”.  It is unclear whether the terms are related.
The term common in claim 22 is a relative term which renders the claim indefinite.  The term common is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention.  It is unclear whether the term “common” is meant to establish “well-known as prior art”, based on [0049] “commonly used drive 42”, such that [0049] teaches the recitation.
The term “common” in claim 22 is further unclear and therefore renders the claim indefinite.  It is unclear whether the term is meant to be interpreted as a “single” drive for multiple elements.
The term “drivable to different away from” in Claim 22 Line 2 is unclear and therefore renders the claim indefinite.  It is unclear whether there is missing recitation.
For the purposes of applying art and providing rejections, the recitation will be interpreted such that Claim 22 Line 2 deleted the term “to different”, and such that Claim 22 is met by the rejection of Claim 20 if the gripper head moves in the weft direction.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 17, 18, 24, 25, 28, 29, 31, 32 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Laukamp et al (USPN 8550123), herein Laukamp.
Regarding Claim 17, Laukamp teaches a device (1) for feeding a first and a second weft thread (6, 6’) in a weft direction (BR) to a gripper head (4) of a loom (it is noted that a recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus satisfying the claimed structural limitations; however, see Fig. 2; Col. 5 Lines 21-25 device 1…for transferring band-shaped weft material 6…from a feed unit…to the insertion element 4 of a weaving machine; Col. 5 Line 30 insertion element 4…is embodied as a gripper; Col. 6 Lines 11-12 insertion element 4 moves with the clamp 10; see Fig. 5 for first/second weft; although recitations herein may be directed to a different embodiment, such as Fig. 1, it is understood that Figs. 2-5 having the same numerals and concepts as recited for Fig. 1 as applicable would also have the recitations apply to Figs. 2-5), the device comprising:
a coupling unit (3, 3’) configured to move back and forth in a warp direction when the device is installed laterally on the loom (Col. 5 Line 64 swivel arm 3; Col. 6 Lines 6-7 Fig. 2 shows...the device...comprises...arms 3; see Fig. 2 for back/forth; wherein the rotation includes movement in a warp direction; Col. 6 Lines 64-66 insertion element 4 carries the weft material 6…into the opened loom shed; see Fig. 2; arms 3 lateral to 4 lateral to loom, see extrinsic evidence Park KR 100822409);
a first and a second feed unit (9, 9’) adjacently arranged in the warp direction on the coupling unit (Col. 6 Lines 6-8 Fig. 2 shows…the device…comprises…arms 3 that are connected by a coupling element 9; see Fig. 5 for adjacent in warp direction; on arms 3/coupling unit),
the first and the second feed units configured to feed the first and the second weft threads, respectively, to the gripper head (see Fig. 5; Col. 6 Line 11 insertion element 4);

Regarding Claim 18, Laukamp teaches the device of claim 17, wherein the coupling unit is positionable such that the position of the first feed unit in the first position of the coupling unit and the position of the second feed unit in the second position of the coupling unit match in the warp direction during weft insertion (see Fig. 5; positions match inasmuch as wefts are fed to position at 4).
Regarding Claim 24, Laukamp teaches the device of claim 17, further comprising a drive configured with the positioning unit (see Fig. 2; Col. 6 Line 38 drive 8).
Regarding Claim 25, Laukamp teaches the device of claim 17, wherein the coupling unit (3, 3’) is configured on a fixed guide part having first guide structures (see Figs. 2, 5; Col. 6 Lines 24-25 weft material 6 is guided between two guide bolts 11; wherein coupling unit 3, 3’ is on a structure of device 1 having bolts 11).
Regarding Claim 28, Laukamp teaches the device of claim 17, further comprising a first weft thread storage unit having a first bobbin (Col. 8 Lines 48-50 feed packages comprise…length for band-shaped materials 6…a package or bobbin exchange can take place),
the first weft thread guided from the first weft thread storage unit to the first feed unit (see Fig. 5, wherein the thread is guided inasmuch as the thread is correctly placed),
and a second weft thread storage unit having a second bobbin (Col. 8 Lines 45-46 feed two different weft materials by means of the device; therefore Col. 8 Lines 48-50 also teaches second weft thread storage unit with second bobbin),
the second weft thread guided from the second weft thread storage unit to the second feed unit (Col. 8 Lines 45-46 teaches that the first weft thread guided as recited would also indicate the second weft guided as recited).
Regarding Claim 29, Laukamp further teaches the device of claim 28, wherein the first weft thread storage unit is arranged above the second weft thread storage unit such that the first weft thread and the second weft thread emerge from the first and second weft thread storage units, respectively, extending one above the other (see Fig. 5, wherein arranged above/extending above is a matter of perspective).
Regarding Claim 31, Laukamp teaches a loom (it is noted that a recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus satisfying the claimed structural limitations; however, see Fig. 2; Col. 5 Lines 21-25 device 1…for transferring band-shaped weft material 6…from a feed unit…to the insertion element 4 of a weaving machine, the weaving machine being a loom; although recitations herein may be directed to a different embodiment, such as Fig. 1, it is understood that Figs. 2-5 having the same numerals and concepts as recited for Fig. 1 as applicable would also have the recitations apply to Figs. 2-5), comprising
a gripper head (4) that is moving through an open shed in and counter to a weft direction (BR) (see Fig. 5; Col. 6 Line 12 insertion element 4; Col. 6 Lines 64-66 insertion element 4 carries the weft material 6…into the opened loom shed; Col. 5 Lines 45-46 motion BR of the insertion element 4 and thus in the weft direction; see Fig. 2 for BR being in/counter to weft),
and the device according to claim 17 for feeding the first and the second weft thread in the weft direction to the gripper head (see rejection of Claim 17).
Regarding Claim 32, Laukamp teaches a method for feeding a first and a second weft thread during production of woven fabric in a loom having a gripper head that draws the first and second weft threads through an open shed along a weft insertion line (if a prior art, in its normal and usual operation, would necessarily describe a device capable of performing the steps of the method or process, then the device claimed will be considered to be inherent by the prior art process or method. When the prior art process or method is the same as a process or method described in the specification for describing the claimed device, it can be assumed the process or method will inherently describe the claimed device capable of performing the different steps of the process or method. In re King, 801 F.2d 1324, 231 USPQ 136 (Fed. Cir. 1986). MPEP 2112.02; as such, for structure for the method: for loom-- see Fig. 2; Col. 5 Lines 21-25 device 1…for transferring band-shaped weft material 6…from a feed unit…to the insertion element 4 of a weaving machine;  for gripper head-- Col. 5 Line 30 insertion element 4…is embodied as a gripper; Col. 6 Lines 11-12 insertion element 4 moves with the clamp 10”; see Fig. 5 for first/second weft 6, 6'; for open shed-- Col. 6 Lines 64-66 insertion element 4 carries the weft material 6…into the opened loom shed; for weft insertion line --see Figs. 2, 3, 5; Col. 5 Lines 45-46 motion BR of the insertion element 4 and thus in the weft direction; although recitations herein may be directed to a different embodiment, such as Fig. 1, it is understood that Figs. 2-5 having the same numerals and concepts as recited for Fig. 1 as applicable would also have the recitations apply to Figs. 2-5), the method comprising:
locating the first and second weft threads next to one another in a plane in a warp direction at an edge of the woven fabric (see Fig. 5 for next to one another in warp direction plane, as BR is weft direction; Col. 7 Lines 6-7 fabric edge 7),
moving the first and second weft threads in a first direction along the warp direction to position the first weft thread at the weft insertion line while deflecting the second weft thread clear of the weft insertion line (for moving—see Figs. 2-5; Col. 8 Line 60-Col. 9 Line 7; especially for deflecting -- see Fig. 5; Col. 8 Lines 52-56 swivel unit 2' with the clamping device 5' is located in the transfer position and is available for the insertion, while the swivel unit 2 with the clamping device 5 with the clamped weft material 6 is located in a parked position); and
feeding the first weft thread along the weft insertion line to the gripper head that draws the first weft thread through the open shed (see Figs. 2-4; Col. 8 Lines 60-66);
moving the first and second weft threads in a second opposite direction along the warp direction to position the second weft thread at the weft insertion line while deflecting the first weft thread clear of the weft insertion line (see Fig. 5; Col. 8 Line 66-Col. 9 Line 7); and
feeding the second weft thread along the weft insertion line to the gripper head that draws the second weft thread through the open shed (see Figs. 2-5; Col. 8 Line 60-Col. 9 Line 7).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 19-22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Laukamp et al (USPN 8550123), herein Laukamp, in view of Park (KR 100822409).
Regarding Claim 19, Laukamp teaches all the claimed limitations as discussed above in Claim 17.
Laukamp does not explicitly teach wherein each of the first and second feed units comprises slides that are movable in the weft direction.
Park teaches a feed unit with a slide movable in the weft direction (see Figs. 9, 10; page 10 Lines 534-537 piston (232) is moved back and forth by a cylinder (233) installed inside the rod body (231), and a pressure inclined surface (234) is formed that fixes the weft (1) while moving forward in the direction of the weft inlet (231a), and allows the weft (1) to be free while moving backward-- piston as slide; wherein the piston is a separate movement/slide from movement from biting rod forward/backward device-- page 11 Lines 620-621  biting bar (23) is advanced...to wait for the weft (1) to advance; page 10 Lines 538-540 biting bar forward/backward device moves the biting bar (23) forward/backward...various cylinder devices, robot arms, linear motors...can be applied).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify each of Laukamp’s feed units with the slide of Park as a known method of effectively providing weft insertion.
Regarding Claim 20, modified Laukamp teaches all the claimed limitations as discussed above in Claim 19.
Park further teaches wherein each of the slides is individually motor-driven in and counter to the weft direction  (indirectly individually motor-driven; see page 10 Lines 538-540 where linear motors drive the biting bar 23 which has the piston 232; for in/counter – see biting bar forward/backward device; see also the “moving forward” and “moving backward” recited of page 10 Lines 534-537 above).
Regarding Claim 21, modified Laukamp teaches all the claimed limitations as discussed above in Claim 19.
Modified Laukamp further teaches wherein each of the slides comprises an actuatable clamp configured to clamp and release the respective weft thread associated with each of the slides (see Park Fig. 10 with clamp formed between 231 and 234; page 10 Lines 535-537 pressure inclined surface (234) is formed that fixes the weft (1) while moving forward in the direction of the weft inlet (231a)”)
and further comprising guide elements upstream of each of the clamps in the weft direction that guide the respective threads from above, below, and laterally (for guide elements on the device--see Laukamp Fig. 4; Col. 6 Lines 24-25 weft material 6 is guided between two guide bolts 11; wherein the above/below bolts also guide laterally inasmuch as the guidance has a dimension in the lateral direction; wherein Laukamp modified with Park would have bolts 11 upstream of the clamp depending on perspective).
Regarding Claim 22, modified Laukamp teaches all the claimed limitations as discussed above in Claim 20.
Park further teaches wherein the common drive is controllable such that each of the slides are drivable to different away from or into the gripper head (as best understood in light of the 112(b) rejections—see rejection of Claim 20).
Claim(s) 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Laukamp et al (USPN 8550123), herein Laukamp, in view of Arrigoni et al (EP 3425094), herein Arrigoni.
Regarding Claim 30, Laukamp teaches all the claimed limitations as discussed above in Claim 28.
Laukamp does not explicitly teach wherein: the first and the second weft thread storage units are aligned in the weft direction and the axes of the first and the second bobbins are aligned in the warp direction.
Arrigoni teaches wherein: the first and the second weft thread storage units are aligned in the weft direction and the axes of the first and the second bobbins are aligned in the warp direction (see Fig. 1 for weft yarns stored in weft direction and axes in the warp direction; [0001] present invention refers to a weft yarn operating device in a gripper loom).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Laukamp’s arrangement to be as taught by Arrigoni as a known arrangement for weft feeders ([0021]).
Allowable Subject Matter
As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with.  See 37 CFR 1.111(b) and MPEP § 707.07(a).
Claim(s) 23, 26, 27 is/are further objected to as being dependent upon a rejected base claim, but may be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:
Regarding Claim 23, none of the prior art of record discloses a device wherein each of the feed units comprise a strip-conveying unit having two revolving strip conveyors positionable in relation to each other, wherein the respective weft threads are conveyable in the weft direction between the strip conveyors, in conjunction with the rest of the structural limitations such as the coupling unit and positioning unit, as set forth in the claim.  The use of utilizing weft yarn between revolving strip conveyors is known in the art of weft insertion devices, but the specific combination of the strip-conveying unit being of the feed unit in Claim 23 while also claiming a specific relationship between the feed units and the coupling unit and the positioning unit in Claim 17, on which Claim 23 depends, such that the feed units are on the coupling unit with the positioning unit configured to position the coupling unit in a first/second position in and counter to the warp direction, as claimed by the applicant is novel.  Specifically, prior art Laukamp et al (USPN 8550123), herein Laukamp discloses the coupling unit, positioning unit, and feeds units as recited in the application.  Prior art Dendo (USPN 3596683) also discloses strip-conveying unit having two revolving strips conveyors positionable relative to one another with weft thread conveyable between the conveyors.  However, none of the prior art discloses, teaches, or suggests such a strip-conveying unit conveying in the weft direction combinable with coupling unit/positioning unit, feed units as recited, such that the conveyors would be movable.  To modify Laukamp with Dendo merely to be as recited in the current application would be impermissible hindsight reconstruction of the applicant’s invention without any disclosure, teaching, or suggestion from the prior art of record, as is presently the case, especially as Dendo’s conveyors do not reposition (which would be required by Laukamp’s positioning unit’s relationship to the conveyors via the coupling unit and feed units).
Regarding Claim 26, none of the prior art of record discloses a device wherein the first guide structures are configured to prevent one of the first or second feed units from moving in the weft direction as the coupling unit is positioned in and counter to the warp direction, let alone the same for second guide structures, in conjunction with other structural limitations, as set forth in the claim.  The use of guide structures is known in the art of weft insertion devices, but the specific functionality of the guide structures to prevent feed units from moving in a weft direction as the coupling unit is positioned in and counter to the warp direction as claimed by the applicant is novel.  Specifically, prior art Laukamp discloses feed units, and a coupling unit positioned in and counter to the warp direction as recited in the application.  Prior art Laukamp also discloses guide structures.  However, none of the prior art discloses, teaches, or suggests that the purpose of guide structures is to prevent the feed units from moving in the weft direction.  To modify Laukamp merely to be as recited in the current application would be impermissible hindsight reconstruction of the applicant’s invention without any disclosure, teaching, or suggestion from the prior art of record, as is presently the case, especially as the existence of bolts clearly allow movement in the weft direction.
Regarding Claim 27—Claim 27 is indicated with allowable subject matter at least for depending on Claim 26, which has been indicated with allowable subject matter.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure and can be used to formulate a rejection if necessary: Umemura et al (USPN 4784191), Edwards et al (USPN 5501250) directed to conveyor-related weft insertion; Debaes et al (USPN 7007723) directed to feed unit parts; Tefag Textile (GB 489980) directed to guide elements; Prohazka et al (USPN 4291731) directed to guide structures; Khokar (USPN 7992596), Lindauer (WO 2020/011915), Dubs (USPN 3517704), Mo et al (US Publication 2018/0127901) directed to storage unit guiding weft thread to feed unit; Mueller et al (USPN 9328437) directed to deflectors.


NEXT OFFICE ACTION: EXAMINER’S AMENDMENT
An examiner’s amendment to the record appears below. Should the changes and/or additions be unacceptable to applicant, an amendment may be filed as provided by 37 CFR 1.312. To ensure consideration of such an amendment, it MUST be submitted no later than the payment of the issue fee.
Authorization for this examiner’s amendment was given in an interview with Stephen Bondura on 5/12/25.
The application has been amended as follows:
Claim 17 Line 8 before “a linear axis” add -–only—
Claim 17 Line 9 before “the linear axis add –only—
Claim 32 Line 7 delete “along “and substitute –consisting of—
Claim 32 Line 12 delete “along” and substitute –consisting of--
Claim(s) 17-34 is/are allowed over the art of record.
Reasons for Allowance
The following is an examiner’s statement of reasons for allowance:
Regarding Claim 17-- none of the prior art of record discloses a device for feeding first/second wefts with a positioning unit configured to move a coupling unit only in a linear axis path in the warp direction, in conjunction with the other structural limitations, as set forth in the independent claim.  The use of devices for feeding first/second wefts having a positioning unit to move a coupling unit is known in the art of weaving, but the specific limited movement of only being in a linear axis path as claimed by the applicant is novel.  Specifically, prior art Laukamp et al (USPN 8550123), herein Laukamp, discloses a device for feeding first/second wefts with a positioning unit configured to move a coupling unit in the warp direction as recited in the application.  Prior art Laukamp also discloses that the movement is both rotational and linear.  However, none of the prior art discloses, teaches, or suggests that the movement would be only linear.  To modify Laukam’s movement merely to be as recited in the current application would be impermissible hindsight reconstruction of the applicant’s invention without any disclosure, teaching, or suggestion from the prior art of record, as is presently the case.
Regarding Claim 31—Claim 31 is allowable for including the allowable subject matter of Claim 17.
Regarding Claim 32—Claim 32 is allowable for reasons similarly indicated for Claim 17.
Regarding Claim 33—Claim 33 is allowable for rewriting the allowable subject matter of Claim 23 in independent form, with reasons for allowable subject matter indicated starting page 11 of the office action 1/30/25.
Regarding Claim 34—Claim 34 is allowable for rewriting the allowable subject matter of Claim 26 in independent form, with reasons for allowable subject matter indicated starting page 12 of the office action 1/30/25.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
