摘要

Unwinding device for textile bobbins comprises two bobbin support arms each provided with a retainer washer for the bobbins, and a yarn guide placed between the two arms. The two support arms are mounted on a rod which grows narrower towards its end, where a hole is inserted for the yarns to pass through. Another washer may be fitted on to the rod to serve as a tension device for the yarns, which pass between the rod and the washer. The device allows two bobbins of yarn to be unwound under constant tension conditions.
