Roller and Clearer Card for Woollen System
topic
The woollen card uses a sequence of worker and stripper roller pairs on the swift cylinder rather than revolving flats, with a condenser dividing the card web into multiple narrow rovings that are rubbed into soft cylindrical slubbings by rubbing aprons for direct feeding to mule or ring spinning without drawing, processing wool fibres at 20 to 50 kilograms per hour per metre card width.
Role
Processes heterogeneous wool fibres of varying length and diameter in the woollen system where deliberate interfibre entanglement rather than parallelisation is required to produce the characteristic woollen yarn structure, with the roller-clearer system providing the gentle carding action that opens and blends wool without the short fibre extraction of the worsted system.
