Apparatus and method for producing patterned tufted goods
First Claim
1. Apparatus for producing patterned tufted goods, comprising means for advancing a backing past a yarn-applying region;
- yarn-applying means disposed at the yarn-applying region for penetrating the backing and for implanting yarn therein, the yarn-applying means being movable transversely to the direction of advancement of the backing for successively implanting yarn along a transverse row;
means for supplying a plurality of different yarns to the yarn-applying means; and
means for controlling the supplying means in accordance with a predetermined pattern to select which of said yarns or combinations of said yarns, if any, is implanted in the backing at each said penetration.

Abstract
In an apparatus and method for producing patterned tufted goods using multicolored or multitextured yarns, continuous lengths of the different yarns are transported pneumatically to a backing opener which is moved transversely across a backing to implant a row of yarn tufts therein. The yarns supplied to the backing opener are controlled in accordance with a predetermined pattern such that at each location in the row any number of the different yarns may be selected for implantation into the backing. The movement of the backing opener may be controlled so as to select the locations in each row at which tufts are implanted, enabling goods with a varying yarn density and with a carved-style pattern to be produced.
