Abstract
A guide is placed between a strand of fibers and a winder, which twists the strand as it is wound. The guide is circular so the strand may be maintained in an unconstrained twisting path between the receiver and the supply as it is being wound and twisted and includes an optical sensor mounted about the area of movement of the filament to detect the presence of the filament and stop the winding process if the strand breaks.
