ABSTRACT:
A carding machine includes a licker-in and a waste separator cooperating therewith. The waste separator includes first and second plates arranged consecutively along a periphery of the licker-in. The first and second plates are spaced from one another by a clearance constituting a waste outlet opening through which waste is discharged with the aid of a circumferential air stream generated by the rotation of the licker-in. The first and second plates each have a pivotally supported end for adjusting their angular position, whereby a radial distance from the periphery of the licker-in is varied for controlling the discharge of waste through the outlet opening. A nozzle is arranged at the licker-in at a location generally diametrically opposite the waste outlet opening. The nozzle has an outlet aperture merging into a space situated immediately radially outwardly of the periphery of the licker-in. A pressurized air generator, such as a blower, is connected to the nozzle for emitting through the nozzle aperture pressurized air for co-directional propagation with the circumferential air stream generated by the rotation of the licker-in to augment the pressure of the circumferential air stream, whereby discharge of waste through the waste outlet opening is enhanced.
