Abstract
Abstract There is provided a yarn guide unit for use with Jacquard controlled warp knitting machines. The guides comprise a plurality of conventional yarn guides and, between each yarn guide there is provided a shorter, rigid tab. The guides and the tabs are mutually oriented so that the head of the tab contacts an adjacent face of its neighboring yarn guide. The contacted face of the yarn guide is always the side of the yarn guide other than that contacted by the influencing Jacquard dropper pin. The effect achieved by the presence of rigid contacting tabs is to both reduce feathering of the yarn guides after withdrawal of the influencing Jacquard dropper pin and to insure that the yarn guide, on the immediately following stitch cycle is correctly oriented in the warp knitting machine with respect to the needle bed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A yarn guide unit for use in Jacquard controlled warp knitting machines comprising: a. a mounting unit, said mounting unit having a transverse axis, b. a plurality of yarn guides each guide being substantially flat and comprising a shaft portion and a head portion connected thereto, and having a first and second face, all of said first faces facing in one direction, and all of said second faces facing in the opposite direction, said shaft portion having a longitudinal axis, c. a plurality of rigid tabs, said tabs being shorter than said guides and comprising a head portion and a shaft portion connected thereto, said shaft portion having a longitudinal axis, said shaft portion of said yarn guides and said shaft portion of said tabs being mounted side-by-side in said mounting unit, said tabs alternating in said mounting unit with said guides, wherein the free end of the head portion of the tabs contacts said first face of the yarn guide adjacent thereto.
Claim 2
Dependent Claim
163 words
A yarn guide unit for use in Jacquard controlled warp knitting machines comprising: a. a mounting unit, said mounting unit having a transverse axis, b. a plurality of yarn guides each guide being substantially flat and comprising a shaft portion and a head portion connected thereto, and having a first and second face, all of said first faces facing in one direction, and all of said second faces facing in the opposite direction, said shaft portion having a longitudinal axis, c. a plurality of rigid tabs, said tabs being shorter than said guides and comprising a head portion and a shaft portion connected thereto, said shaft portion having a longitudinal axis, said shaft portion of said yarn guides and said shaft portion of said tabs being mounted side-by-side in said mounting unit, said tabs alternating in said mounting unit with said guides, wherein the free end of the head portion of the tabs contacts said first face of the yarn guide adjacent thereto.
Claim 3
Dependent Claim
112 words
A yarn guide unit in accordance with claim 1, the longitudinal axes of said shaft portions of said guides lying on a first common plane the planes of said first face and said second face of said guides being perpendicular to said first common plane the longitudinal axes of the shaft portions of said tabs lying on a second common plane said longitudinal axes of said shaft portion of said guides and said longitudinal axes of said shaft portions of said tabs subtending sufficient angles to said transverse axis of said mounting unit to provide contact between said head portions of said tabs and said first side of said adjacent yarn guide.
Claim 4
Dependent Claim
29 words
A yarn guide unit in accordance with claim 2, wherein said angles subtended by the longitudinal axes of said shafts of said guides to said transverse axis is 90°.
Claim 5
Dependent Claim
26 words
A yarn guide unit according to claim 3 wherein the angle subtended by the longitudinal axes of said shafts of said tabs is other than 90°.
Claim 6
Dependent Claim
25 words
A yarn guide unit in accordance with claim 4 wherein said head portion and said shaft portion of said tabs have a common longitudinal axis.
Claim 7
Dependent Claim
47 words
A yarn guide unit in accordance with claim 3 wherein the angles subtended by the longitudinal axes of said tabs to said transverse axis is 90° and said head portion of said tabs is sufficiently oriented towards said adjacent yarn guide to contact the first face thereof.
Claim 8
Dependent Claim
31 words
A yarn guide unit in accordance with claim 2 wherein the angle subtended by said longitudinal axis of said shaft of said guides to said transverse axis is other than 90°.
Claim 9
Dependent Claim
25 words
A yarn guide unit in accordance with claim 7 wherein the angle subtended at said transverse axis by the shafts of said tabs is 90°.
Claim 10
Dependent Claim
25 words
