ABSTRACT:
The invention relates to opening rollers for open-end spinning apparatus, particularly roller which comprise a body on which is wound a helical coil of metallic wire type card-clothing.
The roller body comprises two body parts secured together in end-to-end relationship, and the metallic wire type card-clothing is formed into a pre-set helical coil which is located on an external cylindrical surface of the body, the end flanks of the coil engaging respectively with two abutments one on each of the two parts of the roller body, so that the coil is constrained axially between the abutments in a manner such that adjacent convolutions of the coil are held in abutting relationship.
It is preferred to use interlocking card-clothing wire. It is also preferred to make the roller body parts in plastics material, and to secure them together by an adhesive, and in this manner a disposable roller is produced.
The specification describes methods of refurbishing existing opening rollers, in accordance with the invention.
