It is clean, therefore regardless of the circumferential length of photoreceptor roller, the list from small size (short) to large scale (length) can be carried out
Open the printing of paper.
Thus, it is different from offset press, even in the pattern for printing the size approximate with the circumferential length of impression cylinder
In the case of, also it is not necessarily the photoreceptor roller and the structure of transfer roll with impression cylinder same diameter.Therefore,
It is also that the circumferential length of impression cylinder (supply roll) is only configured to necessary even the printed article of large scale (length)
Circumferential length, can also realize the densification of printing element in itself.
In addition, in the above-described embodiment, the mode of movement of sheet-fed is to be used as supply roll and by-pass roll by the use of being located at
Paper clamp jaw on the surface of 2 impression cylinders of cylinder function, clamps sheet-fed and supporting and fixing sheet-fed, and
And handing-over conveying single paper, due to the position of sheet-fed is fixed using paper clamp jaw all the time, therefore, it is possible to carry out at a high speed,
The production of high-precision printed article.
In addition, on the setting quantity for the circumferential direction of paper clamp jaw being located on the side face of each impression cylinder, in printing
Pattern dimension (length) can also be incited somebody to action with that in the relation of the girth of impression cylinder, can set multiple using covering member
No claw portion is hidden and optionally uses pawl.Needed in the respective embodiments described above alternatively, it is also possible to foundation
Paper clamp jaw is also provided with delivery roll 4,5a, 19a, 19b.Can also be in each embodiment according to printed dimensions
Suitably change the roll neck of each delivery roll.
In the case of the pattern content change in printed on both sides, occur that the surface of each impression cylinder is easily dirty asks
Topic, but by using known technology of coated with ceramic layer etc. on the surface of impression cylinder, or the behaviour of cleaning device is set
Make etc., it can solve the problem that the problem.
