Abstract

A screw head on a container-closing machine has jaws that are pivotable on a holder to grasp a closure cap and hold the cap tightly so that the cap can be screwed onto a container. For pivoting the jaws, the jaws are connected to levers, which rest on an actuating cone that is displaceable coaxially in the holder. The actuating cone is integrally connected to a piston of a cylinder-piston unit, which is likewise disposed coaxially in the holder and the piston is operable by a controlled fuel supply.
