Abstract
A press arrangement which includes a press table, a punch and an adjusting arrangement for selectively adjusting the distance between the press table and punch. A pressure space is provided in the punch which selectively communicates with a pressure medium supply so as to load and relieve the pressure space. A piston is floatingly disposed in the pressure space and cooperates with an element of the adjusting arrangement so as to create a constantly-acting or permanently-acting tension on the adjusting arrangement when the pressure space is filled with a pressure medium.
