- the knitting tool 17 is moved in the direction of movement B along the tool guide 16 and in particular moved out or pushed out beyond the end 22 of the respective tool guide 16 to receive a thread section outside of the tool guide 16 and outside of the guide channel 19 or in cooperation with others Knitwork testify to form a stitch.
- the hardened portion 30 is formed in the plurality of tool guides 16 of the knitting machine part 15 as integ raler area 30 a. That is, the hardened integral portion 30a transitions into the uncured portion 31 without a seam and joint.
- a transition zone 32 may be present between the cured integral region 30 a and the unhardened region 31 in which the hardness increases from the uncured region 31 into the cured region 30.
- the hardened integral region 30a is illustrated by cross-hatching. In the transition zone 32 shown schematically, the cross-hatching is shown less dense to provide the unge to hardened area 31 decreasing hardness schematically darzu.
- the receiving recess 35 is prepared and then the already hardened, separate component 33 as insert 34 in the receiving recess 35th used.
- the hardness therefore changes abruptly between the component 33 or insert part 34 and the non-hardened region 31 adjoining it or at least not sufficiently hardened region of the tool guide 16 (FIG. 3).
- the hardened non-integral region 30 b is therefore pre-defined by the shape of the component 33 and clearly defined without transition zone.
- the support surface 20 extends into the respective hardened region 30 until the end 22 of the tool guide 16, so that the support surface 20 in the respective hardened region 30 has a hardened surface section 36 forms.
