Abstract
A thread guide construction for use in the production of twisted threads. The thread guide is composed of a plate arranged essentially horizontally and having at least three guide eyes arranged symmetrically to one another for a separate guiding of the threads which are to be twisted. A separating member is secured to the underside of the plate between and symmetrical to the guide eyes. The separating member has a width which is less than the spacing between the guide eyes and has a surface thereon converging from the plate toward a terminal location spaced from the plate. The surface is opposed to each of the guide eyes so that when a pulling force is applied to the twisted threads during a twisting operation pulling same away from the plate, the threads are normally free of engagement with the separating member and are in engagement with the surface during a time when the pulling force has been substantially reduced.
