Fine Cleaning Integrated in Card Chute
topic
The existing opening position in the card chute is supplemented with a mote knife, creating a card chute with integrated fine cleaning. A needled cylinder with feed trough produces small tufts with large surfaces; the mote knife immediately eliminates exposed trash. The blowroom production load is distributed over several cards, each performing fine cleaning at considerably lower rates than a standalone blowroom fine cleaner.
Role
This innovation made the separate blowroom fine cleaner superfluous. Yarn quality improves through reduced imperfections (thick places, thin places, neps) and better short fibre content, as the aggressive saw-toothed roll treatment is replaced by gentler distributed processing.
