To guarantee an exact engagement of toothed flanks in the driving gear train of a multi-color sheet-fed rotary printing machine, the gears in the train pertaining to an intermediate printing unit of the machine are power supplied from a driving member which transmit a three-fold power portion in comparison to uniform power portions transmitted by driving elements assigned to the remaining printing units.

Driving system for sheet-fed rotary printing machine

Remote control desk for multicolor printing machine

A pressure control arrangement for controlling pressure between a printing roller and an offset roller by measuring a force exerted in a bearing of the printing roller when the latter rotates with an angle .psi.. The arrangement includes a piezoelectric pickup positioned on the internal surface of the bearing of the printing roller, a measured pressure value processor for receiving a signal from the piezoelectric pickup, an indicator generating a signal corresponding to a desired pressure value and means to compare the first abovementioned signal with the second mentioned signal. The arrangement also includes a positioner circuit which receives the compared signal and applies the same to a drive member which adjusts the position of the bearing of the offset roller thereby adjusting printing pressure between two contacting rollers for printing on sheets of paper.

Device for printing-pressure control

A bearing arrangement for cylinders utilized in printing machines serves for supporting a cylinder trunnion in a machine frame. The bearing arrangement is composed of a sliding bushing surrounding the cylinder trunnion, a flange bearing supported in the machine frame and encompassing the sliding bushing. A second bushing is mounted between the flange bearing and the machine frame which has an outwardly radially extending central collar arranged in contact with the internal axial bore of the machine frame and two bonding elements inserted between the spaces in the second bushing formed by said collar and the axial bore of the frame for compensation of misalignment between the bearing and the machine frame when the cylinder trunnion is inserted into the frame.

Bearing for the cylinders of printing machines

A journal bearing of printing machines for permitting compensation for misalignments between a trunnion and a sliding bushing by means of a flanged bearing sleeve. The flanged bearing sleeve is provided with a plurality of grooves each being in engagement with a wedge which is movable therein, thereby achieving a compensation for misalignments.

A printing press includes an impression cylinder formed with axially directed channels for sheet-clamping means, a radiant dryer arranged above the impression cylinder to radiate heat on the printed sheet, a screening hood mechanism tiltably mounted for movement between an inactive position in which the sheet is exposed to heat rays from the dryer and a screening position; the driving motor is connected to the power source by two parallel power supply circuits each including a separate switch, one of the switches being actuated by a relay which in turn is actuated by series-connected contacts closed respectively when the dryer is in operation, when the driving motor is disconnected, when the printing machine stops, and when the channel for the clamping means on the impression cylinder is not facing the dryer.

A rotary printing machine has at least two successive printing stations. A self-contained aggregate is located between these printing stations and can be inserted and removed from between them as a unit. The aggregate has a transfer roller which receives sheets from one of the printing stations, one or more heaters for heating the sheets on the transfer roller, and a reversing roller which receives sheets from the transfer roller, selectively reverses them and furnishes them to the other of the printing stations.
