Rollers for friction spinning apparatus |
摘要 |
Friction spinning apparatus comprises two rollers arranged in parallel closely spaced relationship so as to define therebetween adjacent the line of closest approach a throat and a fibre feed means for feeding fibres into the throat for twisting into yarn as shown in G.B. No. 2042599. The surface of each of the rollers has a roughness characteristic at most 250 micro inches (6.25 microns) and the roller having its surface moving from the fibre feed means into the throat has a roughness less than that of the other roller by from 20 to 100 micro inches (0.5 to 2.54 microns).
