Abstract
A durable cylinder assembly for a circular knitting machine is described. The cylinder assembly includes a cylinder body having an outer cylindrical face and an upper face including a plurality of spaced-apart substantially radial channels. A shaped circumferential indentation circumscribes an upper end of the outer cylindrical face, and a hardened circular band is matingly engaged with the indentation to define a durable bearing surface for reciprocating elements the knitting machine, e.g. the sinkers and/or needles. The hardened band is preferably formed of heat treated metal and has a discontinuous circumference defined by a single cut, which is preferably single or double biased. The indentation provided in the cylinder body is desirably in the form a right angle, and the band preferably has a rectangular cross-sectional configuration so as to mate securely with the indentation. A method of improving the durability of a knitting machine cylinder by applying such a hardened circular band to the cylinder is also described.
