RUG AND PILE ,fiABRIc MANUFACTURE Filed A E-i1 27, 1934 Patented July 21, 1936 UNITED STATES PATENT. OFFICE RUG AND PILE FABRIC MANUFACTURE Basilia Spesso, Turin, Italy Application April 2'1, 1934, Serial No. 722,609

In Italy May 6, 1933 3 Claims. (c1. 112-1) carried out as if the rod were to be sewn to the canvas, without, however, tightening the successive loops thus formed. The rod is then slipped off leaving a'tube formed by the successive loops of thread. This tube is cut forming the pilewhich is fixed to the canvas by machine-sewn stitches. These stitches can be sewn, after cutting the tube, between the two pile rows, or they can be sewn before cutting the tube laterally of and at the root of the loops. It is preferable to sew two rows of stitches to fix the pile safely.

In carrying out this process ithas been found that the work can be much expedited by employing arod of a much larger section than would be necessary to obtain the desired pile height; it

is thus possible, once the tube of large-sized successive loops has been formed, to sew by means of the sewing machine at least one middle row of stitches thus forming two rows of loops of the suitable size to obtain the desired pile height,

these stitches fixing at the same time the pile. The two tubular rows of loops thus formed and fixed are cut and the same result is obtained which necessitated two operations with the former process.

Consequently, by employing a rod of such size as to allow of two intermediate rows of stitches enabling the formation of three tubular rows of loops, the work obtained from one row of loops is three times as much as compared with the first mentioned process, and so on, as the number of rows of machine stitches increases.

The process according to this invention is carried out rapidly and efiiciently by means of a device consisting of two rods which can be united to form a fork provided "with a handle at one end, these rods being introduced into the largesized loop tube as soon as it is formed, whereupon they are spread apart by means of a suitable spacing member at their free end. The stitches are sewn on the sewing-machine in the space between the two rods which, keep the largesized loops flat and stretched. The needle is thus guided and the work proceeds rapidly and efliciently.

To facilitate the introduction of the fork a suitable pointed ,cap is fitted on the free ends of the rods and is removed when the fork has been placed in position for fitting the aforesaid spacing member on the free rod end. 7 l

The accompanying drawing shows by way of example and diagrammatically three modes of carrying out the process according to this invention and the devices therefor.

Figure 1 is a perspective view showing the procl0 ess at the end of three successive stages, namely formation of the loops, having the required size for giving thedesired pile height, cutting the loops lengthwise and sewing the central row of stitches.

Figure 2 shows also in a perspective view another mode of carrying out the process in which the row of stitchesare sewn laterally of and at the root of the loops and the tube of loops can be out before or after sewing the stitches. 20

Figure 3 shows the higher emciency process in which one middle row of stitches forms from a large-sized loop tube made with the use of a large rod, two tubes of adjacent loops which are safely fixed to the canvas by the stitches, and 25 are cut lengthwise to form the pile.

Figures 4 and 5 show the device employed in carrying out the process according to Figure 3 to stretch the tube of loops and guide the central row of stitches. 30

Figure 6 shows a modified form of the device.

Figure 7 is a view, similar to-- Figure 3, of a modification in which the loop tube is fixed to the basefabric by a plurality of parallel rows of stitches instead of by only one. I 35 As shown in Figure 1,- the work is executed by employing a canvas I, a rod I I of suitable size which isheld against the canvas and a needle in the eye of which the yarn of the desired color is passed. 40

By means of the needle I! successive loops 2 are formed about the rod l I and through the canvas I and when the rod is removed a tube of loops is fixed to the canvas. This tube of loops is out along the upper generatrix and opened and the tufts thus formed projecting from the canvas are fixed by a row of machine-sewn stitches 3 passing through the pile root. By employing successively threads of different colors for determined 50 groups of loops any desired pattern can be obtained. The pile height depends upon the section of the rod ll used.

In the modification shown in Figure 2, the row of stitches 31 are sewn laterally of and at the root 55 of the loop tube and the tube can be out before or after sewing.

In the modification shown in Figure 3, a rod ll of larger size is employed and a tube 4' of larger loops is formed from which two adjacent tubes 41 42 -are obtained by sewing an intermediate row of stitches 5 on the loops. This row of stitches besides forming two tubes from one larger-sized tube secures to the canvas the pile obtained by cutting the top of the two tubes of loops.

In another modification, shown in Figure 7, the loop tube is applied tothe base fabric I in the manner described above, and is flattened against said fabric and fixed thereto by means of two parallel rows of stitches II and I 2, of which one is made on the row of loop roots. The tube is thereby subdivided into three regions l3, l4 and I5, The intermediate region I5 is out along the middle line between the rows of stitches H and I2 and the lateral regions l3 and I4 are cut along the free edge.

In sewing the middle row 01 stitches I preferably make use -of a fork consisting (Figures 5 and 6) of two rods 6 of which one end is connected by a handle 1 which facilitates the operation thereof, and the other end is free.

When the large-sized tube of loops has been formed, a cap] shown in Figure 5 is fitted on the free ends of the fork. This cap draws together the free ends of the rods 6 of the fork and allows of a prompt and easy introduction of the latter into the tube of loops.

When the fork is fully introduced, the cap 1 is removed and replaced by the spacing member 8 which spreads apart the rods 6 as shown in Fig. 4. It is thus possible to sew easily and rapidly the row of stitches to form the two tubes of loops.

Instead of the fork shown in Figures 4 and 5, I may employ the device shown in Figure 6 consisting of two independent rods 61 which may be superposed to. allow of an easy introduction into into the tube of loops and, once they have been introduced, are kept in place at the necessary distance to flatten and stretch the loops by means of the spacing members 9 and Hi.

What I claim is:

1. Process for the 'manufacure of carpets by 6 hand without the use of a loom, comprising applying against a base fabric a rod, forming about said rod a helical winding of pile thread, passing said pile thread at each turn through said base fabric, removing the rod from said winding, cutting the turns along a line midway between the lines at which the wound thread penetrates the base fabric, and fixing said turns to the base fabric by stitches along the root of the turns.

2. Process for the manufacture of carpets by hand without'the use of a loom, comprising app1y ing against a base fabric a rod of which the cross section is ofa peripheral length which is a multiple of the pile length, forming about said rod a continuous winding of pile thread, passing the pile thread at each turn through the base fabric, removing the rod from said winding, flattening said winding against the base fabric, sewing a row of stitches along the middle line of the fiattened winding, and cutting the two tubular portions thus formed along a line midway between the lines at which the wound thread penetrates the base fabric.
