Abstract
Abstract A warp chain receives yarn from a plurality of spools fixedly arranged laterally adjacent a warp knitting machine. The yarn is transferred from the spools to the chain by a plurality of pivotal yarn guides whose free ends pass through arcuate paths during pivoting of the guides. One point of each yarn guide path is adjacent the warp chain for transfer of the yarn thereto and all the arcuate paths intersect at least in one point in the region of the yarn transfer point.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
A warp knitting machine comprising 1. a plurality of spools storing yarn and fixedly arranged laterally adjacent the machine; 2. a warp chain arranged on the machine for receiving yarn from respective ones of the spools and for rotating in an endless path across the width of the machine to lay the warp threads; 3. a plurality of pivotal yarn guides having a free end receiving yarn from a respective one of the spools; and; 4. guide means for the free yarn guide ends for guiding the guide ends through portions of arcuate paths during pivoting of the guides, and one point of each of the yarn guide path portions being adjacent the warp chain for transferring the yarn to the rotating warp chain, and all the arcuate paths intersecting at least in one point in the region of the point of yarn transfer from a respective one of the yarn guides to the warp chain.
Claim 2
Dependent Claim
156 words
A warp knitting machine comprising 1. a plurality of spools storing yarn and fixedly arranged laterally adjacent the machine; 2. a warp chain arranged on the machine for receiving yarn from respective ones of the spools and for rotating in an endless path across the width of the machine to lay the warp threads; 3. a plurality of pivotal yarn guides having a free end receiving yarn from a respective one of the spools; and; 4. guide means for the free yarn guide ends for guiding the guide ends through portions of arcuate paths during pivoting of the guides, and one point of each of the yarn guide path portions being adjacent the warp chain for transferring the yarn to the rotating warp chain, and all the arcuate paths intersecting at least in one point in the region of the point of yarn transfer from a respective one of the yarn guides to the warp chain.
Claim 3
Dependent Claim
34 words
a warp chain arranged on the machine for receiving yarn from respective ones of the spools and for rotating in an endless path across the width of the machine to lay the warp threads;
Claim 4
Dependent Claim
34 words
a warp chain arranged on the machine for receiving yarn from respective ones of the spools and for rotating in an endless path across the width of the machine to lay the warp threads;
Claim 5
Dependent Claim
98 words
The warp knitting machine of claim 1, further comprising a pair of pattern chains of substantially equaL length arranged on the machine for rotating transversely of the warp and for receiving the yarns from the warp chain, the warp chain being inclined in respect of the pattern chains, with one end of the warp chain adjacent the yarn guides being farther removed from the pattern chains than a warp chain end opposite thereto, all the arcuate paths intersecting in an additional point in the region of a yarn transfer point between the yarn guides and the pattern chains.
Claim 6
Dependent Claim
52 words
The warp knitting machine of claim 2, wherein the guide means comprises a guide plate associated with the yarn guides, the free ends of the yarn guides being guided through their arcuate paths in correspondingly arcuate channels in the guide plate constituting said path portions, groups of said channels defining different arcs.
Claim 7
Dependent Claim
20 words
a plurality of pivotal yarn guides having a free end receiving yarn from a respective one of the spools; and;
Claim 8
Dependent Claim
20 words
a plurality of pivotal yarn guides having a free end receiving yarn from a respective one of the spools; and;
Claim 9
Dependent Claim
80 words
guide means for the free yarn guide ends for guiding the guide ends through portions of arcuate paths during pivoting of the guides, and one point of each of the yarn guide path portions being adjacent the warp chain for transferring the yarn to the rotating warp chain, and all the arcuate paths intersecting at least in one point in the region of the point of yarn transfer from a respective one of the yarn guides to the warp chain.
Claim 10
Dependent Claim
80 words
guide means for the free yarn guide ends for guiding the guide ends through portions of arcuate paths during pivoting of the guides, and one point of each of the yarn guide path portions being adjacent the warp chain for transferring the yarn to the rotating warp chain, and all the arcuate paths intersecting at least in one point in the region of the point of yarn transfer from a respective one of the yarn guides to the warp chain.
Claim 11
Dependent Claim
30 words
The warp knitting machine of claim 3, further comprising a shaft supporting ends of the yarn guides opposite to their free ends for pivoting the yarn guides about the shaft.
Claim 12
Dependent Claim
30 words
The warp knitting machine of claim 4, wherein at least a portion of the yarn guides adjacent the yarn transfer points is resiliently bendable for movement in the arcuate channels.
