Combing
The document discusses the combing process, which takes a carded or drawn sliver and minimizes short fibers, fragments, and impurities to produce a cleaner sliver with a more rectangular staple diagram and parallel, straightened fibers. It describes the key steps in combing as removing short fibers, remaining impurities, neps and slubs, and straightening and parallelizing long fibers. Different types of combers are mentioned, including rectilinear, circular, rotary, and hackline machines. The goal of combing is to produce a sliver with maximum possible evenness. Waste removal methods are also summarized.

HAVING MORE OF A RECTANGULAR STAPLE DIAGRAM, WITH THE VAST MAJORITY OF THE CONSTITUENT FIBERS IN A STRAIGHTENED AND PARALLEL STATE.

- 9. WASTE REMOVAL: • ATBOTH SIDES OF THE MACHINE THE COLLECTED WASTE IS REMOVED BY SUCTION NOZZLES AND FED BY VACUUM TO A CENTRAL FILTER HOUSING. WIPERS ON THE CONVEYOR BELT CONTINUOUSLY CLEAN THE HOUSING UNDER THE OPENING ROLLER. • THE APPROPRIATE CLEANING FACILITIES ARE ABLE TO REMOVE MOST EXTRANEOUS, DUST AND TRASH PARTICLES RELIABLY FROM THE RAW COTTON.
