Abstract

The invention relates to opening rollers for open-end spinning apparatus, particularly of the type in which there is a roller body on which is wound a helical coil of metallic wire type card-clothing. The card-clothing coil is located between a pair of abutments, each of which has an annular inner end face in the shape of a helix with an acclivity or step between its maximum and minimum axial displacements, this annular face being complementary in shape to the adjacent end of the card-clothing coil, so that when the ends of the coil are engaged with their respective abutments, there are no recesses between the roller body and the ends of the coil in which lint can lodge. The abutments can be formed by separate distance pieces, or by forming integrally with the roller body, or by moulding after the card-clothing coil has been applied to the roller body. It is preferred to use interlocking type card-clothing wire.
