Abstract

PURPOSE: To prevent contamination due to an offset ink and paper dust from occurring by providing a coating which is ink-repellent on at least one transfer cylinder so that nothing may be printed, and eliminating the arranging of a plate cylinder in a plurality of double printing mechanisms which are operated on the rubber-on-rubber principle, and are arranged in the longitudinal direction. CONSTITUTION: A pair of upper and lower double printing machines 1 and 2 are respectively equipped with a pair of printing mechanisms 3, 4; 9, 10 comprising a pair of plate cylinders 5, 6; 11, 12 and a pair of transfer cylinders 7, 8; 13, 14. Then, on one transfer cylinder 14, a wet mechanism 15 and a washing device 16 are provided. In this case, a roll 17, is printed by, e.g. 1/2. At this time, the printing mechanism 10 is stopped. That is, the transfer cylinder 14 does not print anything on the roll 17. Therefore, the plate cylinder 12 is away form the transfer cylinder 14. That is, on the transfer cylinder 14, an offset blanket 18 and a metal plate 19 which is placed on the offset blanket 18, are stretched, and at the same time, respective one-ends of them are fitted in a chuck 20 of a spindle.

Description of the Related Art Such a printing mechanism is known from the prior art, and when four double printing mechanisms are arranged vertically, it is called an "octuple turret". With such an 8-fold turret, for example, one roll (printing sheet) can be printed on both sides in four colors. If only one color is needed on one side of the roll, stop one printing station,
That is, printing must be interrupted, or the printing mechanism may not be included from the beginning. However, there is a need for a cylinder that acts as a counter pressure cylinder for the printing mechanism on the opposite side of the roll. Colors or paper debris that has set off on this cylinder from the print area in front of the direction of travel must be removed.

The double printing mechanism 1, 2 can also be regarded as part of a so-called 6-fold turret, or an 8-fold turret when another double printing mechanism is arranged on it. The lower double printing mechanism 1 includes printing mechanisms 3 and 4 which are respectively composed of plate cylinders 5 and 6 and transfer cylinders 7 and 8, and the upper double printing mechanism 2 includes plate cylinders 11 and 12 and transfer cylinders, respectively. Cylinders 13 and 14
The printing mechanisms 9 and 10 are included. A wet mechanism 15 and a cleaning device 16 are attached to the transfer cylinder 14.

Is stretched by a tension member for fixing the offset blanket included in. This is, for example, a spin del tension device. Therefore, the edges of the offset blanket 18 and the metal plate 19 are snapped into the Spindel chuck 20 that stretches the offset blanket (FIG. 2). The offset blanket may be a flexo offset blanket, or compressible or non-compressible. However, other simple carrier materials can be utilized. The metal plate 19 can be manufactured from a steel plate, a steel foil or a chrome-plated thin metal plate. The oil-repellent nature of these materials prevents the transfer cylinder 14 from adhering color or waste paper.

ることもできる。Further, the transfer cylinder 14 can be wetted by a wet mechanism 15. This reinforces the anti-setoff effect. The cleanliness of the transfer cylinder 14 is improved by utilizing the cleaning device 16. The cleaning device 16 operates more efficiently with a chrome plated layer than with an offset blanket. The use of a wet mechanism or a cleaning device is not essential in the present invention.
Since it is desirable that the metal plate 19 has low rigidity, it should be manufactured thinly. Alternatively, the metal plate 19 and the offset blanket can be vulcanized or glued together. Instead of the metal plate 19, the offset blanket 18 can be adhered with plastic foil.
