Abstract
The weft thread storage device contains a winding drum arranged eccentrically to a stationary axis. The winding drum is provided with a plurality of thread support rods on the side thereof which is opposite to the eccentric portion thereof. The thread support rods rotate conjointly with the winding drum. The winding reel composed of the winding drum and thread support rods carries the weft thread coils or wrappings. An end face of this winding reel supports a thread guide disk mounted on an intermediate support disk. The thread guide disk is constructed such that the outer circumference thereof everywhere exhibits the same distance from a balloon-breaker housing. In one upper portion of the thread storage device this distance is defined by the upper portion of the winding drum. In this manner it can be achieved that approximately the same centrifugal force arises in the balloon of the withdrawn weft thread at all times, so that the balloon can not be thrown at any location thereof against the inner circumference of the balloon-breaker housing with strongly varying blows. Thus, high loading of the weft thread is avoided so that, in particular, breakage of fibrils of glass fiber weft material is prevented. Hence even delicate weft threads, e.g. glass fiber materials, can be processed. The fabric remains free of fibril fractures such as can arise in withdrawing weft thread under strongly varying centrifugal force and under blows of the thread balloon against the balloon-breaker housing.
