Abstract
Abstract A device for forming coils of thread of a predetermined length on a loom, which includes a coiling element, a rotor for winding a thread around the coiling element to form coils of the thread thereon, the coiling element being mounted to rotate on the rotor, a retaining arrangement for preventing rotation of the coiling element and a means for periodically displacing the coils of thread along the coiling element. The retaining arrangement has two separate retaining means which retain and release the coiling element in a mutually alternating manner so that during the displacement of the coils over the retaining zone of one retaining means, it is positioned or moved away from its retaining zone and the other retaining means is positioned to retain the element.
