Abstract
An automatic printing machine for printing text on film has a main shaft (40) which is provided with an eccentric operative in driving a pressure-plate supporting slide via a knee joint which can be straightened out by a rotary magnet (41). Arranged on the opposite side of the film path is an open bracket structure (30), on which a counter-pressure plate (30) is mounted. The pressure exerted by the counter-pressure plate can be varied with the aid of a force source which is independent of the bracket structure (30), and consequently the bracket structure does not need to take up the counter-pressure exerted by the counter-pressure plate and is not subjected to said pressure.
