ABSTRACT:
A fiber processing line is formed of a plurality of fiber processing machines connected by a conveyor duct. A blower-conveyor is arranged for driving fiber tufts in an air stream through the conveyor duct. The blower-conveyor includes a discharge housing, a rotary impeller supported in the discharge housing; an inlet opening in the discharge housing for drawing the fiber material into the blower axially with respect to the impeller. The discharge housing includes a housing wall generally circumferentially surrounding the impeller and bounding a blower outlet which, similarly to the inlet, is connected to the duct. A waste separator is integrated in the blower-conveyor. The waste separator includes throughgoing openings in the housing wall for providing passages for waste from the fiber tufts upstream of the outlet opening as viewed in a direction of advance of the fiber tufts. The openings are sized to be sufficiently large to allow passage therethrough of waste larger than dust particles and sufficiently small to prevent passage of fiber tufts therethrough.
