Abstract
The nuts or other parts are fed from a store through a supply channel to a guide and from there are fed by a push rod over a tap which is mounted inside a second guide for the nuts. The second guide for the nuts is mounted in a hollow shaft. The hollow shaft and guide are rotated, while the next nut to be machined is pushed over the tap. The second nut guide is supported in the hollow shaft or rollers and can be axially displaced. The guide is held in the hollow shaft by a radially protruding pin. A roller is mounted on the protruding pin which engages with a screw slot of predetermined pitch cut into an extension of the hollow shaft. This enables the nut guide to move axially while it is being rotated.
