Abstract
The slider (17) of an improved slider needle (10) comprises a slot guide (24), wherein the slider springs (18, 19) are provided with a dual deformation on their respective cam follower sections (29). The dual deformation is produced, for example, by a double bend and/or by an additional superficial embossing on a partial surface (34) or also by bending over a section (40) close to the edge. Due to this measure, the guiding precision of the slot guide (24) is improved and, if desired, the penetration space between the two slider springs (18, 19) is also enlarged.
