Lap Preparation Machinery for Combing
topic
Sliver lap machines and ribbon lap machines convert 16 to 24 card slivers into a uniform lap sheet of defined weight per unit length by drafting and doubling sliver assemblies through multiple roller drafting zones, winding the resulting sheet onto a lap roll of defined weight and diameter for feeding to comber machines that require perfectly uniform fibre mass distribution across the full working width.
Role
Produces the precisely uniform lap feed that is prerequisite for consistent comber nipping and combing action, with lap weight per metre uniformity and fibre orientation in the lap determining comber web regularity, piecing quality, and the consistency of noil extraction that governs both combed sliver quality and economic raw material yield efficiency.
