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.

METHOD FOR MANUFACTURING A KNITTED FABRIC COMPRISING A VERTICAL YARN FILAMENT

A method for manufacturing a knitted fabric embodying a basic knit, into which at least one functional yarn filament, such as an electrically conductive yarn filament, is incorporated as a vertical yarn filament (F3). The basic knit is formed from a first and a second yarn (F1, F2) using a plaiting technique. The vertical yarn filament (F3) is incorporated by a third yarn carrier (FF3) positioned, on a third yarn carrier rail located between respective yarn carrier rails for the first and the second yarn carriers (FF1, FF2), at a location at which the vertical yarn filament (F3) is to be incorporated. During formation of a sequence of stitch rows (MR1-MR7) using the first and second yarns (F1, F2), the first yarn (F1) is guided over the vertical yarn filament (F3) on a front side of the knitted fabric and the second yarn (F2) is guided over the vertical yarn filament (F3) on a back side of the knitted fabric.
