Abstract
In weaving face-to-face pile fabrics, in a 2-shot weave, pattern forming portions of pile warps go over 3 wefts while bound-in portions go over only 2 picks. Working pattern repeats--over 3 wefts--are defined for each possible pile warp by aprons which determine the positions of the pile warps. Resultant pile fabrics have precise pattern definition with no crossed piles at pattern borders.

A method of weaving face-to-face top and bottom pile weaves with figure-forming pile warps selectively bound in a top weave, bound in a bottom weave and extending between the top and bottom weaves respectively in bound-in portions and figure-forming pile portions, comprising currently weaving a top and a bottom weaves with a 2-shot weave according to a double weft weaving process, extending top binding warps and bottom binding warps and bound-in portions of figure-forming pile warps over two wefts while passing figure-forming pile portions of the pile warps over three wefts, and imposing working pattern repeats in groups of three double weft shots.
Fabric with figure-forming piles made according to face-to-face pile weaving with plural pile warps selectively bound in a top weave, bound in a bottom weave and extending between the top weave and bottom weave respectively in a bound-in portion and a figure-forming pile portion, comprising the top and bottom weaves formed with a 2-shot weave according to a double weft weaving process, top binding warps and bottom binding warps and bound-in portions of pile warps being extended over two wefts while figure-forming pile portions of the pile warps are passed over three wefts, and working pattern repeats are imposed in groups of three double weft shots.
