A slider spring for a slider used with a slider needle of a loop-forming textile machine includes a closing section for closing a hook opening of the slider needle, a connection section for connecting to a slider body, and a guide section for guiding the slider at a needle body. The slide spring includes at least one bead with a concave bead interior and a convex bead exterior. The slider spring is shaped and configured to be stacked against at least one other slider spring such that the convex bead exterior of the slider spring fits completely within the respective concave bead interior of the at least one other slider spring. A slider for a slider needle includes first and second slider springs as described. A slider needle includes a slider displaceable in a needle longitudinal direction relative to a needle body for opening or closing a hook opening.

Slide spring, slide, slide needle, guide arrangement, and method for producing at least one slide spring

A slide needle, comprising a needle body, which has a needle hook with two spaced-apart lateral hook surfaces. A slide is movably arranged on the needle body between an initial position (I) and a stitch knock-over position (II). The slide has two slide blades. A hook hole on a free blade end of the slide blades is formed by inner hole surfaces. In the stitch knock-over position (II), each inner hole surface lies against an associated lateral hook surface of the needle hook at a contact location and the contact area between the slide and the needle hook is reduced in a height direction (H).

Slide needle

A slider needle () having a partition element () clipped through an insertion slit () in the needle base body (). The partition element () is shaped such that it can be easily inserted in the needle base body, but is still securely held, optionally with some play, as a result of positive engagement. The partition element comprises, preferably as a one-piece component, a spring part () and a foot extension () interacting with the bottom () of the slider slit. Preferably, the foot extensionhas two sections () that are bent in opposite directions, either in a transverse or a longitudinal direction of the otherwise flat partition element (). In the region of the insertion slit (), the back () of the needle base body () has an indentation () so that the bent over sections () cannot project beyond the needle back ().

Slider needle with built-in center strip

In a transfer needle () having at least one transfer spring (), this transfer spring () is held, on its one end, in a preferably lateral pocket or recess of the needle body, while the tip of the transfer spring is positioned in a longitudinal slit of the needle body. This longitudinal slit () has an inlet () that is open in longitudinal direction (L) of the needle body (). The inlet () of the longitudinal slit () is located at an end of the longitudinal slit () away from the hook ().
