Face-to-face weaving represents an alternative method of manufacture of the cut warp fabrics in which two fabrics are woven simultaneously and the pile is produced without the aid of wires. Two separate ground fabrics with a space between them, each with its own warp and weft, are woven on the unstitched double fabric principle, while the pile warp threads interlace alternately with the picks of both fabrics and thus are common to both. The distance between the ground fabrics is regulated according to the required length of pile and as the textures pass forward the pile threads extending between them are cut by means of a transversely reciprocating knife during the weaving process. Upper fabric is thus formed the lower fabric with the pile facing up, and the upper fabric with a similar pile facing down. The fabrics pass in contact with separate take-up rollers and are wound on two fabrics. Fig.1 illustrates double-layer fabrics produced on the face-to-face principle
