Worsted Combing and Gill Box Preparation
topic
Worsted combing uses Noble circular comb or rectilinear French comb machines processing wool slivers through a double-nipping sequence with both top and bottom nip gripping the fibre fringe before circular or rectilinear comb teeth penetrate, followed by gill box drawing stages that maintain fibre parallelisation while reducing sliver linear density through pin-guided drafting between faller gills.
Role
Performs the fibre length upgrading and parallelisation essential for worsted yarn production from wool, cashmere, and alpaca fibres, removing vegetable matter, kemps, and short fibre with noil percentages of 5 to 15 percent depending on raw material quality while producing the highly parallelised combed top that enables fine worsted ring spinning to yarn counts above Nm 100.
