Technical field
The present invention relates to the printing cylinder that a kind of Printing Department that is configured in newspaper offset rotary press is used to install forme.
Background technology
Usually, the printing cylinder in the newspaper offset rotary press is the cylinder body that forme is housed, and mechanism that forme is fixed on the allocation etc. is housed.In addition, with inking roller or damping roller etc. contact, the space of a whole page is accepted printing ink or dumping processing solution, printing ink is transferred on the blanket cylinder that the rubber mass felt pan is housed, so that the walking paper that passes through is printed.
The size that is used for the forme of newspaper printing has long * 2 pages wide (2L2W) of 2 pages, long * 1 page wide (2L1W) of 2 pages, and long * 1 page wide (1L1W) of 1 page uses 2 pages long in Japan mostly.Printing cylinder in the rotary press of this newspaper offset is generally 2 page girths, 4 pages are wide, is called 2 times of printing cylinders, this be known (below, be called " 2 times of cylinders ").Along say with being with, the 22 wide forme modes of long * 2 pages of the page are housed on 2 times of cylinders usually use.
In addition, Fig. 3 is cut apart tectosome (shell type structure) for holding as the mechanism of alignment adjustment usefulness on 2 times of cylinders in the past.Cut apart tectosome and constitute, the register adjusting device 19 of above-below direction (circumferencial direction), left and right directions is housed in separately by driving side printing cylinder 11a and fore side printing cylinder 11b.As the reason of cutting apart tectosome be the alignment dislocation when its maximum purpose is the revisal printing.The variation of the various conditions when the alignment dislocation comprises printing, the error of plate-making or the error on the machinery production, the reasons such as error when forme is installed.Much less, not when cutting apart tectosome, descend move left and right up by making printing cylinder self, can realize alignment adjustment to a certain degree., in view of the multicolor tendency of in recent years printing, adopted the form of adjusting the left and right sides printing cylinder of cutting apart respectively as means of carrying out the alignment adjustment more accurately.In addition, adjust for this alignment, also known a kind of register control adjusting device, this device is, will be in the past the operator by visual judgement printing registration magnitude of misalignment and pass through action button, the mode of the dislocation of the above-below direction of revisal printing cylinder and the dislocation of left and right directions, with read by scanner be printed onto advance on the silk screen alignment mark and automatically adjust alignment adjustment up and down with this as benchmark according to the magnitude of misalignment of alignment.
In common offset rotary press, the reason that makes printing cylinder become 2 times of cylinders is, the printing cylinder of rotary press is in operation, contact with blanket cylinder or rubber cylinder, the strong transfer printing that transfer printing due to these cylinders is used is depressed, the high speed rotary while pushing, wherein, in order to print normally, printing cylinder must have the rigidity of bearing these factors.
