Description

ABSTRACT:
A thread-storage and delivery device for a textile machine having a positive storage for positive thread delivery to the textile machine and a compensating storage for intermittent thread delivery to the machine. A thread drum of the positive storage and a storage drum of the compensating storage are arranged coaxially to one another. The withdrawal area of the storage drum and the winding-up area of the thread drum are arranged axially adjacent to one another, which causes the thread to transfer directly from one drum over to the other. In the transfer area there is mounted a support member which permits the movement of the thread in a peripheral direction. The winding directions of both drums are opposite to one another and both drums are moved relative to one another with a peripheral speed which, as an average over the operating time, corresponds approximately to twice the thread-delivery speed of the positive storage.
