Integral common duct with suction hoods for waste removal

In a fiber processing machine including a series of clothed rolls for entraining fiber along a circular path;

• a housing surrounding the rolls;
• at least two waste discharge openings adjacent the rolls for passage of waste from the fiber entrained by the rolls;
• a separate mote knife bounding each said waste discharge opening;
• a suction hood adjoining each waste discharge opening for receiving waste passing through the respective waste discharge opening;
