Abstract

A displacement pick-up arrangement for the position detection of a plunger is a component of a pressing station of a section of an I.S. glass-forming machine in which a plunger is inserted into a mold recess of a parison mold holding a glass gob at this time, and includes a ring-shaped core which is carried by a piston rod mounted to said plunger. The core forms an actuating element for changing the inductivity of a coil which is arranged in a ring-shaped frame between a cylinder and a guiding cylinder for the plunger.
