Thread supply device for textile machine having common thread control and tension sensing element

摘要

A thread supply device for a textile machine, such as a knitting machine, having a drive. The thread supply device includes a thread drum on which a thread issuing from a supply bobbin can be wound tangentially to form an intermediate thread supply and from which the thread can be removed over a removal edge of the drum. A thread-control element is positioned adjacent to the path of thread removal in the vicinity of the removal edge, and against which the thread abuts laterally due to the tension of removal during a positive thread supply mode. The thread-control element also functions as a thread tension-sensing element and is movable responsive to a decrease in the tension of the removed thread such that, when this tension falls below a predetermined value, this element activates a switching structure which stops the machine drive.
