Definitions
- the invention relates to a sheet-fed offset rotary printing press in series construction according to the preamble of the first claim.
- a sheet offset rotary printing machine of the type mentioned is e.g. known from DE-C 1 107 246.
- grippers provided on the circumference of the turning cylinder for back and front printing grasp the trailing sheet edge and remove it from the previous double-sized transfer cylinder. The grippers then swivel inward about their own axis until they rest against an inner stop element.
- Two-color grippers for two-color printing which are additionally provided on the circumference of the turning cylinder, also pivot inward about their own axis until they rest against another inner stop element.
- the trailing edge of the sheet is transferred from the inward and outward-facing grippers to the two-color grippers that are aligned with it, so that the sheet is turned, the trailing edge of the sheet now becoming the leading edge.
- suction cups are additionally provided on the circumference of the turning cylinder, namely in the direction of rotation of the turning cylinder behind the grippers. These suction cups also hold the trailing sheet edge.
- the object of the invention is to provide a sheet-fed offset printing press in which the sheet travel provided in perfecting with two transfer cylinders and the double-size transfer drum for single-sided multi-color printing only allows via the double-size transfer drum as the only drum between two double-size printing cylinders and at the same time reduced the intermediate size from printing unit to printing unit for a compact series construction. becomes.
- the switchable sheet travel according to the invention enables a series construction with a shortening of the intermediate dimension from printing unit to printing unit to less than the diameter of the double-sized transfer drum 7, because in the perfecting, the successive three drums or transfer cylinders are more compactly connected to one another compared to the usual arrangement.
- two-color printing unit consists of two plate cylinders 1, 2, two blanket cylinders 3, 4 and two double-size printing cylinders 5, 6, between which a transfer cylinder 17, a double-size transfer drum 7 and a reversing drum 21 are arranged are not.
- the sheet transfer is generally carried out by mechanical gripper transfers.
- the inking units on the plate cylinders 1, 2 are not shown.
- the double-sized transfer drum 7 can be changed in the direction of rotation and, like the transfer cylinder 17, is arranged in pivotable bearings 8 and 16, respectively. The movement takes place according to the arrows drawn in FIGS. 1 and 2 into positions 7 'and 17', respectively.
- the gripper rows 12, 13 fastened to the double-sized transfer drum 7 have pliers grippers. Through these measures, the double-sized transfer drum 7 for a switchable between face and reverse printing (Fig. 1) and single-sided multi-color printing (Fig.
- smoothing devices 14, 15 are provided on the sheet end (see arrows, FIG. 1).
- suction devices on the circumference of the turning cylinder and blowing or suction devices for spreading the sheet onto the double-sized transfer drum 7 in a known manner in order to hold the trailing sheet edge and to ensure a lubrication-free sheet run.
- Sheet travel and transfer take place in single-sided multi-color printing with only one double-sized transfer drum 7 between double-sized printing cylinders 5, 6 and also in perfecting with a transfer cylinder 17, a double-sized transfer drum 7 and the reversing drum 21 between the double-sized printing cylinders 5 , 6 each in a known manner, so that a further explanation is unnecessary. It is only necessary to make the appropriate switchovers.
- the pivoting of the transfer drum 7 and transfer cylinder 17 is not limited to the mentioned pivotable bearings 8, 16, but other known devices can be used, by means of which the geometric position and the direction of rotation of a drive axis can be changed for the purpose of switching the sheet travel.
