Embodiment Construction

[0063] exist figure 1 The paper offset printing machine on which the present invention is based is shown in , the drive arrangement of which is in figure 2, where five printing units D1 to D5 of an offset paper printing press are shown in side or top view with an impression cylinder G and a transfer or wraparound guide cylinder in between ( Umführtrommeln) T. The printing paper to be printed is fed via the feed reel A to the impression cylinder G of the first printing unit D1. This is followed by the deflection drum W, which is upstream of the impression cylinder G of the second printing unit D2. During the changeover from front-side printing to front-side and reverse-side printing, the printing sheet is deflected after the printing unit D1 and fed via the deflection drum W to the impression cylinder G in the printing unit D2 .

[0064] The main drive motor HA is driven into the longitudinal axis LW, which is driven into the drive wheels of the impression cylinders G of th...

Abstract

A drive for a sheet-fed offset printing press having a feeder (1), one or more printing units (2 to 8), one or more varnishing modules (9) or other printing press units and a deliverer (10) is to operate more exactly. A back-pressure cylinder and a transfer drum (11, 13, 14) are provided in each printing unit (2 to 8) for sheet transport. All sheet-conducting cylinders and drums (11, 12, 13, 14) are connected to a continuous drive wheel train (15). Drive wheels (16, 16.1) are connected to the back-pressure cylinders (12). One or more drive printing units (33) are provided in the drive for transmitting the drive power from the main drive motor (HA) directly into the drive wheel train (15) of the sheet-fed offset printing press.

Description

technical field [0001] The invention relates to a drive in a tandem configuration (Reihenbauweise) for a paper rotary printing press for a paper offset printing press consisting of a printing press unit with a sheet feeder , one or more printing units, none, one or more varnishing modules and a delivery, wherein for the transport of the printing paper to be printed through said paper offset printing machine in the paper transport direction, it is provided in the first printing unit There is at least one feed reel and impression cylinder, in the further printing unit and in the varnishing module there is respectively at least one transfer reel and impression cylinder and in the delivery there is at least one Reel reel, wherein all paper-guiding cylinders and reels are drive-technically connected to each other by means of a drive train arranged in succession, and wherein, within said drive train, at least a first drive wheel is correspondingly connected to the embossing The cyl...
