Abstract
An opening roller for open-end spinning machines comprises a cylindrical roller body having a saw- tooth wire wound helically onto its outer surface, the wire having a base region wider than that portion of the wire which is toothed, the wire being wound under tension onto the outer surface of the roller body and fixed at its ends to the roller body. Base regions of adjacent turns of the sawtooth wire are separated from one another by a gap. The radio of the height H to the width B of the base region is less than 1 preferably in a range 0.4 to 0.6. The height of the base region is preferably less than 0.5 mm and desirably equal to the maximum thickness of the tooth region.
