. Application filed December 27, 1926. Serial No. 157,081.

This'invention relates to a method of making a pile fabric.

One of the objects of the invention is to is inexpensive use asa rug and in various other ways in which pile fabrics are commonly used.

In accordance with the invention the pile fabric is formed by first attaching a layer or ply of felt or unspun fibre to a fabric ply (such for instance as burlap) by pricking through both plies, some of the fibres of the unspun ply throu h and interlocking them with the fabric p ly and thus making a compound layer, and then applying to the .fabric ply face of the compound layer another layer or ply of unspun fibres and subsequently pricking again through the compound layer and the secondnamed ply of unspun'fibres' thereby to carry fibres from the first-named ply of unspun fibres through the fabric ply and into the second ply of unspun fibres. This second ply of unspun fibres is subsequently stripped off from thefabric and in doing so the pile of the fabric is drawn up from the fabric face. The complete fabric thus when ready for use will have a bottom layer or ply of unspun fibres, a superposed fabric ply and formed from. fibres which have been drawnthrough the fabric ply.

- In order to' give an understanding of the invention I have illustrated in the drawings aselected embodiment thereof which will now be described after which the novel features Wlll be. pointed out in the appended claims.

Figs. '1, 2 and'3 illustrate successive steps in the process of making the pile fabric;

Fi 4 is a sectional'view illustrating the pile fabric when completed. a The pile fabric shown in Fig. 4 comprises a bottom layer or ply 2 of unspun fibres, such for instance as felt, an upper ply 1 which is desirably fabric, and a pile 3 which is formed by fibres 2 which have been'drawn through the fa llC ply 1.

In making this type of fabric I first superpose a ply'or layer 2 of unspun fibres suchfor instance as felt, upon a fabric 1 and then subject the su erposed layers or pllies to the action of nee les 5 which prick t two plies and in doing so carry a portion of this operation carrying in the nature of a coarserough the,

the fibres of the unspun material 2 through the fabric ply 1 as shown at 6, the fibres 6 projecting below the lower face of the fabric 1. This operation serves-to unite the two plies 1 and 2 thus making a compound layer or, fabric 10.

Another similar compound layer or fabric 11 is made as shown in Fig. 2 by laying a sheet 7 of unspun or felted fibres on a fabric ply 8 and then subjecting the superposed plies to the pricking operation of needles 5 as above described, which will cause some of the fibres of the ply 7 to be carried through and interlocked-with the fabric 8 as shown at 9.- When thetwo compound layers or fabrics have thus been formed they are superposed one on the other as shown at the left in Fig. 3, with the fabric-ply side of the compound layer 10 resting agalnst the top face of the unspun ply 7 of the compound layer 11. These superposed compound layers are then subjected to another pricking operation by means of the needles 5 and this pricking operation will carry additional'fibres of the ply 2 through the fabric 1 and will also carry fabricsapart will pull up a thick an long A pile 3 on the face of the fabric 1. When the twocompound fabrics are thus separated the pile fibres 3 which are pulled up from the face of the fabric 1 are of different length thus making an irregular pile.

The fabric is finished by shearing the. pile 3 so as to make an even pile as shownin Fig. 4.

I claim:- 1. The method of making a pile fabric which consists in forming two compound layers each composed of a ply of unspun fibres anchored to a-fabric ply, superpo'sing said compound layers with the fabric ply of one layer lying against the unspun p1 y of the other layer, pricking through both compound layers to carry fibres of one unspun to carr fibres from one 1ply of unspun ply through the intermediate fabric pl? and fibres t rough .the fabric p y and into the into the other ply of 'unspun fibres an then other ply of unspun fibres and then pulling pulling the two compound layers apart the last-named ply from the fabric ply there- 15 5 thereby pulling up a pile from the face of by to pull up a pile from the fibres after thefabrie ply. they have been pricked through the fabric 2. The method of making a pile fabric pl which consists in superpos' two layers or in testimony whereof, I have signed my plies of uns un fibre and a abrie ply with name to this specification. 10 the fabric p y between those of the uns un fibres, pricking through the superposed p ies THOMAS S.
