Abstract

PURPOSE:To permit the printing of long (tens meters) printing medium by a method in which plural flexible relief printing plates having different contents are continuously supplied to a plate cylinder and wound around the cylinder detachably, and printing of different contents is orderly made on papers advancing between the plate cylinder and a compression cylinder. CONSTITUTION:A long paper 1 is sent out of a paper supplier 11 and inserted between a plate cylinder 2 and a compression cylinder 3. Flexible relief plates 4 are sent one by one onto a chain conveyer 6 from a relief printing plate stacked section 5 into the space between a pulley 8 and the plate cylinder 2. The flexible relief plates are coupled with a guide pin provided at the edge of the plate cylinder 2, wound around the plate cylinder 2, and turned. Printing is made between the plate cylinder 2 and the compression cylinder 3 by means of the relief plates 4 inked by an ink roll 9, and the relief plates after the printing are separated from the plate cylinder by a vacuum sucker 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a letterpress printing method and (1) an apparatus for the same.
Letterpress printing method for printing
Regarding V.

Traditionally, there are three types of printing methods: flat presses, circular presses, and rotary presses.
/i7 to -C printing''1, and there are two types of paper: θ), which is printed on a roll of paper, and σ), which is printed on sheets of paper.

And when printing I; (=come, for example, page σ),
First, print a certain number of pages with the same content σ) using a plate consisting of
Next, change the plate and print a certain number of pages with other σ) content, and in this way, after printing (,・(-many σ゛) pages for each, it 1:) θ) each of the printed pages. Gathering all the members and organizing them, it became possible to bind the book for the first time.If each member did not organize the book well, problems such as missing pages and misaligned pages would occur. In addition, when the printing force θ is 0), the printable surface level 1 is limited to a constant σ), and the series &'A:
In order to print the long length σ) also V), it is necessary to perform post-processing (α), such as joining together, without tI-, 70) storage] several states and quality. - L's small cane match?) Tsuta.

The present invention σ) For purpose G, following the above-mentioned specifications σ) Overcoming the inconveniences and defects to produce a single sheet of l length d) The length of the paper in the longitudinal direction τ progress,
