Abstract
Abstract A holding device for an automatic warp knitting machine, in which a plurality of knitting needles or needle-like instrumentalities, such as yarn guides, are held in rigid alignment. The device includes an anchor bar in which one end of each needle is embedded. Advantageously, the bar is made of lead, or similar alloy, and is itself embedded in a plastic plate which, together with the anchor bar and the needles, forms the entire assembly. The ends of the anchor bar are formed into flanges which inhibit dimensional changes in the plastic, thereby maintaining the alignment of the needles.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
A holding assembly for holding a plurality of needle-like knitting machine instrumentalities in rigid alignment, which comprises: 1. an anchor bar of a first material comprising lead and having one end of each of said needle-like instrumentalities embedded therein,said first material forming a strong bond with said needle-like instrumentalities; 2. a plate-like structure of a second material comprising a synthetic resin, said structure being molded about said anchor bar and a portion of said needle-like instrumentalities; and 3. first and second flange portions of said first material formed at the extremities of said anchor bar, said first and second flange portions confining therebetween the portion of saiD plate-like structure which is molded about said bar and the portion of said needle-like instrumentalities, whereby dimensional changes in said second material tending to affect the alignment of said instrumentalities are inhibited by the restraining influence of said flange portions.
Claim 2
Dependent Claim
147 words
A holding assembly for holding a plurality of needle-like knitting machine instrumentalities in rigid alignment, which comprises: 1. an anchor bar of a first material comprising lead and having one end of each of said needle-like instrumentalities embedded therein,said first material forming a strong bond with said needle-like instrumentalities; 2. a plate-like structure of a second material comprising a synthetic resin, said structure being molded about said anchor bar and a portion of said needle-like instrumentalities; and 3. first and second flange portions of said first material formed at the extremities of said anchor bar, said first and second flange portions confining therebetween the portion of saiD plate-like structure which is molded about said bar and the portion of said needle-like instrumentalities, whereby dimensional changes in said second material tending to affect the alignment of said instrumentalities are inhibited by the restraining influence of said flange portions.
Claim 3
Dependent Claim
21 words
The holding assembly according to claim 1, wherein said anchor bar is trapezoidal in cross-section and tapers towards said needle-like instrumentalities.
Claim 4
Dependent Claim
27 words
a plate-like structure of a second material comprising a synthetic resin, said structure being molded about said anchor bar and a portion of said needle-like instrumentalities; and
Claim 5
Dependent Claim
27 words
a plate-like structure of a second material comprising a synthetic resin, said structure being molded about said anchor bar and a portion of said needle-like instrumentalities; and
Claim 6
Dependent Claim
27 words
The holding assembly according to claim 1, wherein said anchor bar has at least one concave depression formed therein, in a direction along the longitudinal axis thereof.
Claim 7
Dependent Claim
69 words
first and second flange portions of said first material formed at the extremities of said anchor bar, said first and second flange portions confining therebetween the portion of saiD plate-like structure which is molded about said bar and the portion of said needle-like instrumentalities, whereby dimensional changes in said second material tending to affect the alignment of said instrumentalities are inhibited by the restraining influence of said flange portions.
Claim 8
Dependent Claim
69 words
first and second flange portions of said first material formed at the extremities of said anchor bar, said first and second flange portions confining therebetween the portion of saiD plate-like structure which is molded about said bar and the portion of said needle-like instrumentalities, whereby dimensional changes in said second material tending to affect the alignment of said instrumentalities are inhibited by the restraining influence of said flange portions.
Claim 9
Dependent Claim
30 words
The holding assembly according to claim 1, wherein said anchor bar has a plurality of fins formed thereon to increase the resistance thereof to motion relative to said plate-like structure.
Claim 10
Dependent Claim
20 words
The holding assembly according to claim 1, wherein said needle-like instrumentalities comprise yarn guides for an automatic warp knitting machine.
Claim 11
Dependent Claim
25 words
