771,624. Spinning yarns etc.; processes &c. ; tuft cutting mechanism for pile fabric looms. FELTON, W. Nov. 25, 1955 [Dec. 17, 1954], No. 36538/54. Classes 120 (3) and 142 (2). A cutting device for cutting continuous lengths of yarn or thread includes an elongated holder consisting of a block 1 having clamping plates 2 to clamp a plurality of cutting blades 3 to the block 1 with their cutting edges 4 projecting therefrom at an angle. The holder is adapted to move in a path, such that to each blade 3 is imparted a motion along an oval or circular path which intersects the yarn to be cut, by a guide 5 in which the holder is slidable crosswise of the yarn, and a means for imparting motion to the guide 5 towards and away from the yarn. The driving mechanism of the holder and guide may consist of cranks or cams, 8, 11. |
