Abstract

A processing device configured to process a printed sheet (3) includes an embossing device (5) configured to perform emboss-processing of the sheet (3), and a final processing device configured to perform final working processing of a surface of the sheet (3). The final processing device includes at least one of a number printing device (6) configured to print a number on the sheet (3), and a varnishing device configured to apply a varnish to the sheet (3). There is provided a processing device capable of performing emboss-processing without disturbing sheet feeding when performing the final process of printing by performing the emboss-processing at an appropriate stage of a printing step.

First claim

The invention claimed is:

1. A processing device configured to process a printed sheet, comprising:
an embossing device including an embossing impression cylinder and a plate cylinder and configured to perform emboss-processing of the sheet; and
a final processing device configured to perform final working processing of a surface of the sheet,
wherein the final processing device comprises
a varnishing device arranged downstream of the embossing device and configured to apply a varnish to both surfaces of the sheet,
wherein the varnishing device includes
a first varnishing impression cylinder which is adjacent to the embossing impression cylinder and is configured to receive the sheet directly from the embossing impression cylinder;
a second varnishing impression cylinder; and
a skeleton cylinder which is arranged between the first varnishing impression cylinder and the second varnishing impression cylinder and is configured to receive the sheet from the first varnishing impression cylinder.

2. The processing device according to claim 1 , wherein
the embossing impression cylinder includes a sheet holding device configured to hold the sheet and a first plate holding device configured to hold a first plate, and is a single-diameter impression cylinder including having an effective impression area corresponding to one sheet; and
the plate cylinder includes a second plate holding device configured to hold a second plate, is configured to be able to contact and separate from the single-diameter impression cylinder, and is a single-diameter plate cylinder having an effective impression area corresponding to one sheet.

3. The processing device according to claim 2 , wherein the first plate holding device and the second plate holding device are capable of holding both an intaglio printing plate and a relief printing plate.
