ABSTRACT:
An open-end spinning machine rotor is formed from sheet metal as an annular body. The body has an interior fibre collecting surface on which discrete fibres are continuously deposited and from which the tail end of a yarn is continuously drawn-off. The body is shaped to provide first and second portions converging to a region of maximum diameter at which is located the interior fibre collecting surface. In this way, the internal fibre collecting surface is free from surface imperfections which would adversely affect the operation of the rotor.
