KNITTING MACHINE WITH A GUIDE CHANNEL AND A KNITTING ELEMENT GUIDED THEREIN

摘要

The invention relates to a knitting machine with a guide channel and a knitting element guided therein, wherein the knitting element is accommodated and guided in the guide channel in a substantially moveable and interlocking manner. In addition, when viewed in the manufacturing state or in the production and output state, the knitting element (3) is designed with a surface structure at least in sections on at least one opposing knitting element side flank (3a, 3b) when viewed in cross-section and/or the guide channel (4) is formed with a surface structure at least in sections on at least one channel side wall (4a, 4b) facing the knitting element side flanks (3a, 3b), wherein the surface structure has a plurality of elevations (1) spaced apart from one another, which are arranged and designed so that they contact punctiformly and/or linearly on the respective facing area of the knitting element side flanks (3a, 3b) and/or the channel side walls (4a, 4b) during operation, and wherein the surface structure additionally has a plurality of depressions (2) spaced apart from one another which are arranged and designed so that they form a plurality of lubricant reservoirs spaced apart from one another, in which a part of a fluid lubricant, in particular a lubricant oil, introduced into the guide channel (4) is accommodated, and thus forms a lubricant film in the area between the knitting element side flanks (3a, 3b) and the channel side walls (4a, 4b) during operation. According to the invention, the surface structure has a material ratio (Rmr) of 50% at a cutting height (c) of 0.4 μm to 3 μm, preferably only at a cutting height (c) of 0.6 μm to 1.6 μm, according to DIN EN ISO 4287.
