Zusammenfassung:The machine for cutting an internal screw thread in a nut has a carrier for a tap (20), a feed successively feeding nut blocks onto the tap and a motor causing relative rotation between the carrier and the blocks. The feed has a reciprocating pusher (28) for the blocks towards the leading end of the tap along a feed path which is aligned with the leading end. The feed has a fluid actuated piston and cylinder unit (31) which is associated with the pusher to apply to it the force needed to push the blocks onto the tap. The pressure in the piston and cylinder unit is preferably adjustable.
