Assembly to break down sliver, into a thin web of loose fibers, has a curve in the collection surface path which matches the loosening roller curvature at the transfer zone

摘要

The assembly to break down sliver into loose fibers has a sliver loosening roller (19) which transfers loose fibers as a thin web on to a collection surface (5). The collection surface has a curvature at the transfer zone (33) which matches the curvature (34) of the roller. The collection surface speed is 10-30% faster than the surface speed of the rotating roller. The gap between the feed zone (21) for the sliver (2) and the transfer zone is larger than the maximum fiber length.
