摘要：
A method of manufacturing an opening roller assembly for an opening roller of an open-end spinning machine is provided. A hardened cylindrical sleeve made of a hardenable steel alloy has at least one circumferential groove formed in an outer cylindrical surface. After forming the at least one circumferential groove, the cylindrical sleeve includes a remaining wall section having a thickness no greater than 2.2 mm extending from the base of the cylindrical groove to an inner surface of the cylindrical sleeve. circumferential ribs are formed when the circumferential grooves are formed. The ribs have a base thickness of no greater than 0.7 mm. The sleeve wall radial thickness is about 0.06-0.72 times the height of the circumferential ribs. The circumferential groove base width is about 2.5 to 3.5 times the base thickness of the circumferential ribs. Next, at least two axially extending grooves are formed in an axial direction across the cylindrical sleeve circumferential ribs, thereby forming combing teeth having fine tooth points and a slender shape for opening slivers into individual fibers.
