Abstract (en)
[origin: US4346500A] The converging space between the moving-in or inbound surface of a loosening roll and the surface of a feed roll contains a suction duct, which is brought into close vicinity of the fibre loosening zone located between the two rolls, and which is used for sucking off of dust released in this zone. The suction duct is supported by the body forming the fibre feeder trough. Detrimental deposits of impurities in the subsequent processes, e.g. in the open-end spinning rotors, thus are greatly reduced.
