Abstract

Electronic thread protector which ensures double protection of thread feed with a single spring comprises a frame 20 cm high along the top of which are mounted the thread tensioners and thread guides, and a spring carrier consisting of a threaded bar which prevents lateral sliding of the spring. A vertically and tiltably adjustable contact receiving bar mounted on an insulating support and maintained under tension allows free movement of the spring without establishing contact so long as there is thread available. A flat member with holes maintains the spring under tension. When the thread breaks, the spring resumes its original form and establishes contact between the spring carrier and the contact-receiving bar.
