Abstract
Abstract An apparatus for the manufacture of nonwoven pile fabrics suitable for carpeting or the like includes an array of loopforming members arranged in paired relationship, the array being adapted to travel past a loop-forming station wherein loops of yarn are formed. Each of the loop-forming members comprises a relatively elongated bead portion upon which yarns are disposed to form loops when the yarns are inserted between a pair of said loop-forming members, and a relatively elongated flexible slat portion at one edge integral with the bead portion and adapted to be fixed at the other end to a dimensionally stable carrier.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
A pair of slatlike elements useful in an apparatus for producing a pile fabric, each of said elements comprising a bead portion extending along one edge of said element, a slat portion integral with said bead portion and extending therefrom, said slat portion having an offset portion along that edge thereof remote from said bead portion, the aforesaid offset portion having a section or length parallel with respect to said slat portion, the parallel section of one of said pair of elements being fixed in contact with and opposed to the parallel section of the other of said pair of elements and the bead portions of said elements being disposed in adjacent, parallel relationship.
Claim 2
Dependent Claim
114 words
A pair of slatlike elements useful in an apparatus for producing a pile fabric, each of said elements comprising a bead portion extending along one edge of said element, a slat portion integral with said bead portion and extending therefrom, said slat portion having an offset portion along that edge thereof remote from said bead portion, the aforesaid offset portion having a section or length parallel with respect to said slat portion, the parallel section of one of said pair of elements being fixed in contact with and opposed to the parallel section of the other of said pair of elements and the bead portions of said elements being disposed in adjacent, parallel relationship.
Claim 3
Dependent Claim
25 words
A pair of elements in accordance with claim 1 including a carrier, the slat portions being fixed together at their offset portions to said carrier.
Claim 4
Dependent Claim
35 words
An array of pairs of elements in accordance with claim 1 wherein said pairs are fixed to a carrier and wherein said pairs of elements making up said array are disposed equidistant from each other.
Claim 5
Dependent Claim
188 words
Apparatus for producing a pile Fabric comprising an array of pairs of elements in accordance with claim 1, planklike support means, said planklike support means carrying said array of pairs of elements, the elements making up said pairs being fixed to said planklike support means at the parallel sections of said elements, means for continuously moving said support means past a loop-forming station, loop-forming means at said loop-forming station adapted for up-and-down movement relative to said pairs of elements for inserting and pressing downwardly yarn between each of said pairs of elements to form loops of yarn therebetween and gauge means associated with said loop-forming means and adapted for up-and-down movement relative to said elements for insertion between a pair of said elements containing the previously formed loops of yarn therebetween to a distance not exceeding the distance said loop-forming means was previously inserted thereinto so as to cause said previously formed loops of yarn to be withdrawn to an amount determined by the depth or distance to which said gauge means is inserted between the following pair of said elements to form additional loops of yarn therebetween.
