主权项

1. A sheet-fed printing press, comprising:
a foil transferring portion for transferring foil onto a sheet; a printing portion for performing printing on the sheet; an embossing portion for giving an embossed finish to the sheet; and a dry heating portion configured to dry and heat up the sheet, such that a temperature of the foil transferred onto the sheet exceeds 40° C. to lower an elastic recovery force of the sheet, such that raised and recessed shape formed by the embossing portion are maintained, wherein the embossing portion is disposed at a position located on a downstream side of both the foil transferring portion and the printing portion in a transporting direction of the sheet, and the dry heating portion is disposed at a position located on the downstream side of both the foil transferring portion and the printing portion in the transporting direction of the sheet, and located on an upstream side, in the transporting direction of the sheet, of a position where embossing finish is given to the sheet by the embossing portion, wherein the printing portion is disposed at a position located on the downstream side of the foil transferring portion in the transporting direction of the sheet, and located on the upstream side of the embossing portion in the transporting direction of the sheet, wherein the embossing portion includes:
a counter cylinder supported rotatably and used for holding and transporting the sheet; anda processing cylinder disposed so as to be opposed to the counter cylinder and used for working together with the counter cylinder to give embossing finish to the sheet, and wherein the foil transferring portion includes:
a transport cylinder supported rotatably and used for holding and transporting the sheet; anda press cylinder disposed so as to be opposed to the transport cylinder, supported rotatably, and used for transferring the foil onto the sheet that is held on and transported by the transport cylinder, and the sheet-fed printing press, further comprising: driving means for driving the printing portion and the foil transferring portion; and means for connecting-disconnecting a drive of the press cylinder, the means for connecting and disconnecting the driving, by the driving means, of the press cylinder of the foil transferring portion, wherein the foil transferring portion includes pressing-cylinder mounting-dismounting means for moving the press cylinder between an operating position, where the press cylinder transfers the foil onto the sheet held on and transported by the transport cylinder, and a retreat position, where the press cylinder is positioned away from the operating position so as to make the foil be not in contact with the sheet.
