Abstract

975,402. Warp let-off motions. DENCO A. G. Dec. 9, 1960 [Dec. 14,1959], No. 42531/60. Heading D1E. A movable back rest 21 operates linkage controlling an infinitely variable belt drive which adjusts the warp beam let-off to maintain a constant warp tension. In Fig. 1 the back rest 21 and a lever 68, with a ratchet 73, are pivoted about 16 and a pneumatic cylinder 71 tends to pivot the back rest 21 clockwise about the pivot 16 to tension the warp, the lever 68 moving a rod 59 to the left decrease and to the right to increase warp let-off. If warp tension increases the back rest 21 pivots anticlockwise about 16 moves rod 59 to the right which adjusts the belt drive to increase the speed of the beam 13 driven from the shaft 35. At beat-up a cam 24 lifts a lever 22 so that a pawl 74 engages the ratchet 73 to prevent the rod 59 moving to increase let-off. Other embodiments with infinitely variable belt drives are described.
