ABSTRACT:
In order to remove broken threads and debris from textile drawing equipment having a drawing cylinder, a suction pipe connected to an air pressure sink is provided with a triangular suction opening at the drawing cylinder for removing the broken threads and debris. For substantially improved performance at essentially the same air throughput, the suction pipe, in continuation of its triangular suction opening, is provided with a triangular cross-section being congruent with the triangular suction opening and extending along a major portion of the length of the suction pipe, such as to the vicinity of its connection to the air pressure sink.
