Abstract
Device for transforming a rotary movement of a drive element eccentrically arranged about a rotary spindle into a linear movement of a slide means with an assured guidance during the linear movement and fixed end positions, whereby for the linear guidance of the slide means the drive element constructed as a guide pulley or the like engages in a guide slot, but leaves the latter on reaching the slide means end position, characterized in that on the slide means (3) are provided two rollers (14,15) or similar stops, which in the end positions of slide means (3) in each case slide onto and engage on a bar (32,33) or similar reference edge, the bars (32,33) freeing the rollers (14,15) during the linear guidance of slide means (3) and while maintaining a spacing (b).
