Thread draw-off nozzle and open-end spinning device having a thread draw-off nozzle
An open-end spinning device having a thread draw-off nozzle and a thread draw-off nozzle for an open-end spinning device, the thread draw-off nozzle having a thread-guiding surface which extends between an entry opening and a draw-off opening and which tapers in the shape of a funnel toward the draw-off opening. In order to provide a thread draw-off nozzle and an open-end spinning device having a thread draw-off nozzle which allows controlled production of the thread, the thread draw-off nozzle has a blocking element, which protrudes from the thread-guiding surface and which has a thread stop surface designed such that the thread stop surface blocks a thread from circulating over the thread-guiding surface.
Method for a Textile Machine and a Textile Machine
The method in accordance with the invention for a textile machine, in particular a spinning or a winding machine with multiple similar workstations (1), serves the purpose of delivering a thread (7) to a coil (12), laying the thread (7) on the coil (12), for winding the thread (7) on the coil (12) and for finding a thread end wound on the coil (12) by means of a suction nozzle (4), whereas the thread end is sucked in by means of an opening turned towards the coil circumference that serves as an extraction mouth (10) of the suction nozzle (4). The thread (7) runs through the suction nozzle (4) during the delivery to the coil (12), whereas it enters through an additional opening in the suction nozzle (4) serving as an inlet mouth (9) for the thread (7) and exits the suction nozzle (4) through another opening, in particular through the extraction mouth (10). A textile machine, in particular a spinning or a winding machine, features multiple similar workstations, in each case with a thread delivery device for delivering a thread (7) to a coil (12), a thread traversing device for laying the thread (7) on the coil (12), a winding device for winding the thread (7) on the coil (12) and a suction nozzle (4) for finding a thread end wound on the coil (12), whereas the suction nozzle (4) features an opening turned towards the coil circumference that serves as an extraction mouth (10) for sucking in the thread end. The suction nozzle (4) features an additional opening serving as an inlet mouth (9) for the thread (7), and the thread (7) runs through the suction nozzle (4) during the delivery to the coil (12), whereas it enters the suction nozzle (4) through the inlet mouth (9), and exits the suction nozzle (4) through another opening, in particular the extraction mouth (10).
System and method for guiding fibers
A fiber guide that guides fibers in a fiber processing system. The fiber guide has a surface having apertures through which fibers can pass in a direction from an upstream side of the surface to a downstream side of the surface. The apertures include at least one pair of apertures adjacent to and spaced from one another. The inlet of the first aperture is offset from the inlet of the second aperture. The offset is in the direction in which the fibers pass from the upstream side of the surface to the downstream side of the surface. A distance (d1) between the inlet of the first aperture and the inlet of the second aperture is larger than a distance (d2) between the first aperture and the second aperture measured transverse to the direction in which the fibers can pass.
