2 Claims.

There is disclosed herein a pile fabric comprising rows of looped tuft-yarns, binder warps and stulfer warps laid between the rows, and a cycle of four weft shots to each loop.

In this weave each tuft is looped around the first and third shots of weft threads of a cycle, the first shot overlying and the third shot underlying the stuffer threads of one cycle; the second and fourth shots of the cycle underlie the stuffer threads and the loops of the tufts. The binder and stuffer warp threads are laid between the rows of tufts, and the roots are thus spaced apart. In like manner also the weft shots space apart the roots of the tufts. By reason of the spacing apart of the roots both longitudinally and transversely the upwardly projecting ends of the tufts are opened up, giving a rich appearance to the fabric. Moreover, the tuft yarns are by this weave provided with a backing by which they are supported and lifted with resultant economy in the length of yarn required for a given height of tuft. Also the weave is such that the backing is sufficiently open for the tuft yarn and pattern to be visible, though not subject to wear, at the back. The fabric herein shown resembles in appearance what is commonly known as semi-oriental moquette or tufted carpet.

In the accompanying two sheets of drawings which form a part of this description,

Figure 1 is a face View of the fabric with the tufts sheared off at their roots on the horizontal plane II of Figs. 2, 3, and 4.

Fig. 2 is an edge view parallel with the warps on the line 11-11 of Fig. 1, showing in full line the course of the first binder warp threads.

Fig. 3 is a similar view on the line III-III of Fig. 1, showing in full line the course of the second binder warp threads.

Fig. 4 is an edge view parallel with the weft threads on the line IVIV of Fig. 1.

Figs. 5, 6, 7 and 8 show the separation of the warp threads in the loom for the first, second, third and fourth shots of weft threads respectively.

The fabric is woven from a warp with tuft yarns ill of worsted, a set of first binder threads I l adjacent to one side of each of the tuft yarns, a set of second binder threads l2 adjacent to the other side of each of the tuft yarns, and stuffer warps [3 between the binder warps. These stuffer warps are shown in groups of three threads. They are slightly heavier than the binder threads, and are heavily tensioned in the weaving.

For the first shot of weft threads, as shown in Fig. 5, the stuifer threads and the tuft yarns are down and the shuttle 14 carries the shot l5 over them and under the binder threads which are up. For the second shot of Weft threads, as shown in Fig. 6, the second set of binder threads are down and the shuttle carries the shot i6 over these and under the first set of binder threads, the stuifer threads, and the tuft yarns which are up. For the third shot of weft threads as shown in Fig. 7, the first and second sets of binder threads are down, and the tuft yarns are down and the shuttle carries the shot ll over them and under the stulfer threads which are up. For the fourth shot of weft threads, as shown in Fig. 8, the first set of binder threads are down and the shuttle carries the shot l8 over them and under the second set of binder threads, the stuffer threads, and the tuft yarns H]. The tuft yarns are raised above the others and above the wire l9 by which the tufts are cut. The wire pulls up the tufts, thereby shortening the horizontal portions of the bights, drawing the first and third shots of weft threads in each loop towards each other and drawing the third shot of weft thread over the second shot of weft thread, whereby less of the expensive tuft yarns is. left buried in the backing and more is brought up into the tufts.

The tuft yarns show at the back particularly between the second shot of weft and the fourth shot of the preceding cycle.

I claim:

1. A pile fabric comprising rows of looped tuft yarns, and a backing with a warp of stuffer threads between the rows of tuft yarns, a first shot of weft threads above the stuffer threads about which tufts are looped, a second shot of weft threads below the stuffer threads and under the looped tufts, a third shot of weft threads below the stuifer threads about which tufts are also looped, a fourth shot of weft threads below the stuffer threads and under the looped tufts, a first binder thread between each row of looped tufts which overlies the first shot of weft threads and underlies the third and fourth shots of weft threads, and a second binder thread between the rows of looped tufts which overlies the first shot of weft threads and underlies the second and third shots of weft threads.

2. A pile fabric comprising rows of looped tuft yarns, and a backing with a warp of stuffer threads between the rows of tuft yarns, a first shot of weft threads above the stuffer threads about which tufts are looped, a second shot of weft threads below the stuifer threads and under the looped tufts, a third shot of weft threads below the stuffer threads about which tufts are also looped, a fourth shot of weft threads below the stufier threads and under the looped tufts, a first binder thread between each row of looped tufts which overlies the first shot of weft threads and underlies the third and fourth shots of weft threads, and a second binder thread between the rows of looped tufts which overlies the first shot of weft threads and underlies the second and third shots of weft threads,'the binder threads being on each side of and adjacent to each of the rows of tufts and the stufier threads being between the binder threads.
