High speed card - has sliver discharge roll associated with cleaning brush and microswitch tripped by lever sensing excess sliver thickness to avoid jamming

摘要

Sliver discharge appts. associated with a high speed card has a discharge roller whose surface is provided with a fitting consisting of a helically wound wire of triangular isosceles cross-section, which co-operates witha known doffer. Appts. further has a pair of sliver feeding rollers for guiding the sliver to a calendering device. Discharge roller co-operates alsowitha cleaning brush. For use with cards operating at sliver speeds of 140 to 150 m/mim. Jams are automatically relieved and carding elements are protected against damage.
