ABSTRACT:
A device for adjusting a chuck to axially tension core tubes and consisting of a driven spindle and of a spindle nut that can be displaced by the spindle and is attached to the chuck. The object is to improve the chuck-adjusting device to the extent that the force involved in tensioning the core tube can be precisely prescribed. The chuck is accordingly connected to the spindle nut by a frictional connection that is subjected to pressure from a force generator and can be released from that pressure by the recoil exerted at the core tube during axial tensioning.
