Process and apparatus for shredding fibre tows into staple fibres

摘要

The shredding of fibres in the form of bands or strands to staple fibres with short staple length and fibre velocities of up to 6,000 m/min is attained by winding the fibre tow around a cutting ring with adjustable blades and cutting up the fibre tow by pressure rollers pressing radially on the winding. The feeding of the fibre tow is synchronized with the pressure rollers, as these rollers are fixed in supporting discs which rotate above and below the cutting ring with the same velocity as the depositing nozzle.
