Abstract
An auxiliary needle is supported by a shiftable and rotatable slide rod which extends in a slightly inclined position relative to the vertical and is guided by an extension in a guide slot. The upper portion of the guide slot extends at an angle relative to the slide rod. Therefore, if moved from its rest position downwardly into its working position, the auxiliary needle performs first a combined rotary and translational motion, and then, upon penetrating a workpiece, only a straight longitudinal motion.
