Abstract
Metallic toothed wire is disclosed for textile fibers processing elements for processing cotton, synthetic fibers and the like, and particularly for use with cleaning rollers in which the surface is clothed with the toothed wire. The toothed wire comprises a plurality of teeth having a tooth distance (4,17) between the teeth (3,16) in a circumferential direction of at least 10 mm. The teeth (3,16) have a height which extends to about one third of the tooth distance, and preferably no more than 3 mm. The teeth have an ascending rear portion (5,20) which ascends in a rear inclination over about half the tooth distance from a tooth base (9,19) to a tooth tip. An undercut portion (8,21) which has an undercut inclination extends downwardly from the tooth tip to the base. A positive front angle (7,23) is between the rear inclination and the undercut inclination within a range of 10 degrees to 40 degrees. A trough interspace (26) is defined between the undercut portions and tooth bases of adjacent teeth (3,16) for receiving waste particles from fiber cleaning of substantial length which are not broken or comminuted.
