Sliver drawing roller - has humped surface projections to give defined roughening

The upper surface of the drawing roller, to draw sliver for spinning, has projections with rounded humps at least each in the contact zone. The arithmetical mean roughness value Ra is 0.8-7.0 micron. ADVANTAGE - The structure simplifies mfg of the drawing rollerss and improves the drawn quality of t...
