Abstract
A yarn rupture-suction installation or broken end-collecting installation for the drafting systems or drafting gears of spinning machines, comprising a respective suction head for each drafting system connected with an air pressure sink and having a substantially slot-shaped suction opening associated with a delivery or feed roller of each drafting system. The suction opening extends from one end situated close to the spinning triangle to an end situated closer to an air pressure sink in the direction of flow of the air. The method of operating such installation and for preventing clogging of the suction head thereof contemplates imparting to a ruptured yarn piece or broken end leading to the rupture location a different position than the path of travel of the fiber material which is further delivered to the drafting system.
