Abstract
The invention relates to a method and a device for identifying and expelling foreign material in a stream of fibres consisting of compressed textile fibres. To provide a method and a device which continuously check the stream of fibres in industrial use also at high speeds, the checking conditions being constant over a long period, the stream of fibres is compressed in portions (62), driven by positive fit, optically detected and inspected for the presence of foreign material. The device has at least one roller-shaped element (14, 15) provided with teeth (21, 22) for engagement in the stream of fibres, between which teeth (21, 22) light-transmitting elements (23, 24) are arranged.
