US 11,578,436 B2 · Knitting machine parts and method for production thereof

Abstract

A knitting machine part comprises a plurality of tool guides, each for one knitting tool. Each tool guide has a hardened region. The majority of the hardened regions are formed to be integral without seams or joints which transition integrally into adjacent, non-hardened regions. At least one hardened region of the knitting machine part is formed by a non-integral region, in that a hardened, separate component is arranged there, which forms the non-integral hardened region. The component can be designed as an insert part and inserted in a receptacle recess. The integral regions are preferably formed by induction hardening of a knitting machine part which is not yet hardened, wherein a separate hardened component can be arranged in each insufficiently hardened region in order to provide a hardened, non-integral region.

Dependent claims

A knitting machine part (15), comprising:

multiple tool guides (16) that are individually configured to guide a knitting tool (17) that is movable in a movement direction (B),
wherein individual ones of the multiple tool guides (16) each comprise a knitting tool support surface (20) for supporting the knitting tool (17), the knitting tool support surface (20) formed by a hardened section (30) and a non-hardened section (31), wherein the hardened section (30) has a hardness that is greater than a hardness of the non-hardened section (31),
wherein a majority of the hardened sections (30) are configured as integral section (30a) that are each monolithically configured with the non-hardened section (31) of a corresponding tool guide (16) of the multiple tool guides (16) such that the knitting tool support surface (20) formed by the monolithically configured hardened and non-hardened sections (30a, 31) is seamless,
and wherein at least one of the hardened sections (30) is configured as a non-integral section (30b) that comprises at least one separate component (33) that is fixedly connected with the non-hardened section (31) of a corresponding tool guide (16) of the multiple tool guides (16).
