Filed: 1991-07-10
Abstract: PURPOSE:To prevent the generation of winding crease caused by the thickness of selvedge by stopping the traversing motion of a winding shaft of a winding beam at both traversing ends and at an intermediate position, thereby changing the winding position. CONSTITUTION:A traversing apparatus for a winding beam 20 of a loom is provided with a motor 4 having changeable rotational direction and rotational speed and a conversion mechanism 5 to convert the rotational motion to reciprocating motion. A winding shaft 3 rotating in the winding direction is reciprocated by the motor 4 between two positions P1 and P2 separated in the direction of traverse. The count number of synchronous setting signals inputted into a counter 16 increases at a definite rate as the progress of weaving and, when it reaches a level set by a setter 15, the count number is reset to zero to form a sawtooth wave. The motor 4 is driven by a normal-reverse rotation signal synchronizing to the sawtooth wave based on the operation signal of a speed setter 18. The conversion mechanism 5 traverses the winding shaft 3 and, at the same time, stops the traverse motion at the positions P1 and P2 for a prescribed period.
