WOVEN PILE FABRIC.

Application filed October 28, 1925.

This invention relates to improvements in woven pile fabrics of the 'Vilton7 class wherein sets of pile threads are floated in lapping relation between upper and lower weft strands or threads and extended upwardly at certain intervals between adjacent upper weft strands to forni the pile of the fabric, the pile threads being confined between the upper and lower weft strands, and the weft strands being bound into the fabric by binding warp threads.

The invention aims to cheapen the cost of production of fabrics of this class and to provide a novel fabric structure which can be produced in less time than heretofore and which will be. strong and durable when in service.

rThe desired aiin is accomplished by interweaving a continuous thread forming the weft strands with the pile threads and binding warp threads in a novel manner, as will be hereinafter explained; and the invention consists of the elements and the co1nbina tions of them hereinafter described and particularly claimed.

In the accompanying drawings illustrating the invention:

Figure l is a side view of a pile fabric embodying my invention, as seen from one of the lateral edge portions thereof.

Figure 2 is ay side view of the fabric as seen from the opposite lateral edge portion thereof.

Figure 3 is a long-itudinal section through the fabric, on line 3 3 of Fig. 1.

Figure 4'is a transverse section through the fabric, on line 4 4 of Fig. 3.

Referring to the drawings, 2 designates pairs of .binding warp threads, 5 sets of pile threads, and 6 a continuous thread which forms upper and lower pairs of weft strands 7 and 8, respectively.

The pairs of binding warp threads 2 are arranged atv spaced intervals throughout the width of the fabric and the sets of pile threads 5 alternate with the pairs of binding warp threads 2 and are arranged between next adjacent pairs thereof, as clearly shown in Fig. 4, and they extend longitudinally of the fabric or in the general direction of the warp threads 2. Any desired or suitable number of pile threads may be e1nployed in each set 5 thereof, six threads Serial No. 65,298.

being shown in the drawings in each set for convenience of illustration.

The upper and lower pairs of weft strands 7 and 8 extend transversely of the fabric from side to side thereof above and below the sets of pile threads 5, respectively; and the threads of the pairs of binding warp threads 2 pass above and below the upper and lower pairs of weft strands 7 and 8 and cross each other within the body of the fabric, as shown in the drawings, and thereby bind the pairs of weft strands 7 and 8 into the fabric and cause them to bind the sets of pile threads 5 into the fabric.

The pile threads of the sets thereof are floated side by side longitudinally through the body of the fabric between upper and lower pairs of weft strands 7 and 8 and between laterally adjacent pairs of binding warp threads 2; and, at certain regular intervals throughout the length of the fabric one thread of each set is extended upwardly between adjacent upper pairs of weft strands 7 to form the pile 9 which may be cut, as herein illustrated, or which may remain uncut, as desired. Thus, by employing different colors in the pile threads of the several sets 5 thereof, different designs may be produced in the fabric, the threads of the several sets 5 being floated between the pairs of weft strands 7 and 8 when not appearing upon the upper surface of the fabric in the formof the pile 9.

At the lateral edge portion of the fabric shown in Fig. l. the weft strands of the upper pairs 7 thereof are connected to the weft strands of the lower pairs 8 thereof by loop portions lO and l1 which are formed by the continuous thread 6, so that the continuous thread extends around the sets of pile threads 5 in connecting the upper and lower pairs of weft strands 7 andv 8 at'one lateral edge of the fabric and thereby prevents the pairs of weft strands from being withdrawn from between the binding warp threads 2 and the pile threads 5 or displaced longitudinally in the fabric in the direction of the arrow 12 in Fig. 4 or toward the edge portion of the fabric shown in Fig. 2. The portions 11 of the continuous thread 6 eX tend only around the ioated portions vof the pile threads 5, and the portions l() alsoexaround the crossed pairs' of binding:

warp threads 2, as shown in Fig. 1, which further prevents such withdrawal or longi- `tudinal displacement of the pairs of weft strands 7 and 8.

fit the lateral edge portion of the fabric shown in Fig. 2 there is provided a supple` mental binding thread 13 which extends lon gitudinally of the fabric or in the general direction of the binding warp threads 2 and pile threads 5; and the upper and lower pairs of weft strands 7 `and 8 Yare connected to this supplemental thread 13 by loops 1d; and 15 formed .by the continuous thread 6 and forming extensions of the pairs of weft :strands 7 Vand 8 and extending around or embracing the thread 13, as shown in Figs. 2 ande.' Thus, the supplemental binding vthread; lprevents the pairs of weft strands 7 andf8 from being withdrawn from between thebinding warp threads 2 andthe pile threadsl 5v or displaced longitudinally in the fabricin the direction of the arrow 16 in Fig. 4 or toward the edge portion of the fabric shown in Fig. 1.

The course of the continuous thread 6- through the fabric is as follows: From the point- 17 shown 1n Fig. 1, 1t extends above the sets of pile threads 5 from the edge of the fabric shown in Fig. 1 to the edge shown inFig. 2. Itthen forms a loop 14 around the supplemental binding thread 13 and eX- tends back above'the'sets of pile threads 5 to the edge of the fabric shown in Fig. l. It then'extends around thesets of pile threads 5 to the bottom thereof andforms a loop 10 from which it extends beneath the sets of pile threads 5 to the edge of the fabric shown. in Fig.. 2 and there forms a l v 'loop' 15 around the supplemental binding thread 18, and from this loop 15 it extends back beneath ythe Sets of pile threads 5 to theedge vof the fabric shown in Fig. 1. It then extends around the sets ofpile threads 5 and around the crossed adjacent threads of l15A woven pile fabric comprising pairs Y of binding warp threads alternating with sets of pile threads extending in the direction of the binding threads, and a continuous thread ypassing under and over the pile threads and around the same at one lateral edge portion of the fabric and forming pairs of weft strands above and below the pile threads, a supplemental binding thread eX- tending in the directionof the warp threads at the lother lateral edge portion of the fabric, each pairrof upper Vand lower weft strands forming a loop which embracessaid supplemental,thread, the upper and lower pairs of weft` strands confining the sets of pile threads between them and being bound intothe fabric by the pairs ofbinding warp threads, and the pile threads `of each set thereof extending upwardly between adjacent Yupper pairs of weft strands at certain intervals and forming pile and 'being floated side by side in lapping relation between the upper and lower pairs of weft strands and between laterally adjacent pairs of binding warp threads when. not forming pile.

2. A woven pile fabric comprising pairs of binding warp threads alternating with sets of pile threads extending in the direction of the binding threads, and a continuous thread passing under and over the pile threadsand forming pairs of weft strands above and below the same, the continuous thread passing around the pile threads at one edge portionof the fabric vat certain intervals and around pairs of binding warp threads at the same edgefportion of the fabric at certain intervals` a supplemental binding thread extending in thedirection 'of the warp threads at the other lateral edge portion of the fabric,eachpair of upper and lower weft strands forming a, loop which embraces" said supplemental thread, the upper and lower pairs of weft strands conlfiningthe sets of pile threads between Ithem and being bound into the fabric by the pairs of binding Vi'varp threads. and the pih` threads of each set thereof extending upwardly between adjacent ,upper pairs of weft strands at certain intervals and forming pile and being floated side by side in lapping relation betweenv the upper and lower pairs of weft strands and between 'laterally adjacent pairs ofrhindng warp threads when not forming pile.

In testimony whereof I affix my signature. 1
