Abstract
Abstract Warp knitting machine having a zone wherein knitting needles are disposed and means for supplying warp threads to the needles, includes a device for filling a weft to the warp threads having a plurality of holder members located in the vicinity of respective weft reversal locations disposed at opposite lateral edges of a fabric web being knitted by the machine, thread guide means movable along a continuous travel path and cooperating with the holder members for making the weft ready by looping the weft about respective holder members at opposite weft reversal locations, the holder members at each of the weft reversal locations being mounted so as to be displaceable successively in direction toward the needle zone.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
163 words
In a warp knitting machine having a zone wherein knitting needles are disposed and means for supplying warp threads to the needles, a device for feeding filling wefts to the warp threads comprising means for making the weft ready outside the needle zone and guiding the weft to the warp threads, said make-ready means including a plurality of holder members located in the vicinity of respective weft reversal locations at opposite lateral edges of a fabric web being knitted by the machine, a single thread guide cooperating with said make-ready means for making the weft ready, said thread guide being movable always in the same direction along a contInuous travel path between said weft reversal locations and intercepting said holder members at said weft reversal locations, respectively, so that the wefts are looped about respective holder members at the weft reversal locations, and means for successively displacing said holder members at each of said weft reversal locations in direction toward said needle zone.

Claim 3
Dependent Claim
13 words
Warp knitting machine according to claim 1, wherein said holder members are tooth-shaped.
Claim 4
Dependent Claim
13 words
Warp knitting machine according to claim 1, wherein said holder members are pin-shaped.
Claim 5
Dependent Claim
44 words
Warp knitting machine according to claim 1, wherein all of the holder members at each weft reversal location are displaceable in common about an axis disposed parallel to a line extending between said weft reversal locations at both edges of the fabric web respectively.
Claim 6
Dependent Claim
22 words
Warp knitting machine according to claim 4, wherein the holder members at each weft reversal location is secured to a rotatable disc.
Claim 7
Dependent Claim
18 words
Warp knitting machine according to claim 1 including a thread clamp cooperating with each of said holder members.
Claim 8
Dependent Claim
30 words
Warp knitting machine according to claim 1, wherein each of said holder members is formed with a recessed contour for preventing a weft looped thereon from sliding off the same.
Claim 9
Dependent Claim
35 words
Warp knitting machine according to claim 1, including a thread clamp cooperating with each of said holder members, said holder members being formed with contours for preventing a thread looped thereon from sliding off therefrom.
Claim 10
Dependent Claim
46 words
Warp knitting machine according to claim 1, wherein at least at one of said weft reversal locations, at least one thread feeder for opening a weft loop of the weft supplied by said traveling thread guide means is disposed for cooperating with the respective holder members.
Claim 11
Dependent Claim
32 words
Warp knitting machine according to claim 9, wherein said loop-opening thread feeder is formed as a thread guide member and is displaceable between said thread guide means and the respective holder members.
Claim 12
Dependent Claim
46 words
Warp knitting machine according to claim 10, wherein said thread feeder is fixedly mounted on a shaft and is rotatable with said shaft, and including a planet wheel also mounted on said shaft and having teeth meshing with an inner toothing formed on a stationary member.
Claim 13
Dependent Claim
68 words
Warp knitting machine according to claim 1, wherein said thread guide means is revolvable between the plurality of holder members at both weft reversal locations disposed at opposite lateral edges of the fabric web for continuously depositing weft in the former of a looped cycloid thereon, and including means for placing the weft around more holder members at one of said weft reversal points than at the other.
Claim 14
Dependent Claim
57 words
Warp knitting machine according to claim 1, wherein the weft is made ready on said holder members in lengths successively displaceable toward said needle zone and wherein, in delivery position of one of said weft lengths to said needle zone, a locking member cooperates with each of said holder members for holding fast the succeeding weft lengths.
