Problems solved by technology

[0005] However, in the above-mentioned conventional number printing device, although two numbers can be printed on one side of the sheet in one pass, it cannot be double-sided printed on one side and the other side of the sheet in one pass. Number
Therefore, when printing numbers on one side and the other side of the sheet, in the number printing machine, once the number is printed on one side of the sheet, the paper must be fed again to print the number on the other side of the sheet. Time consuming and can also result in less accurate registration of numbers printed on one side with numbers printed on the other side

Abstract

A numbering and imprinting machine includes: a numbering printing unit for one surface including an impression cylinder (141) and a numbering cylinder (142); a first numbering printing unit for the other surface including an impression cylinder (143) and a numbering cylinder (144); a drying unit for one surface including a drying cylinder (151) and a drying device (153); a second numbering printing unit for the other surface including an impression cylinder (145) and a numbering cylinder (146); and a drying unit for the other surface including a transfer cylinder (161), a drying cylinder (152), and a drying device (154).

Description

technical field [0001] The present invention relates to a number printing device for printing a number on a sheet, and a printing machine using the number printing device. Background technique [0002] As a conventional number printing device that carries out number printing to a sheet, for example, after the first number is printed on the outer surface (one side) of the sheet held by the platen cylinder of the first number printing unit with a number cylinder, the number is then transferred to the sheet. The cylinder transfers the sheet to the impression cylinder of the second number printing unit to hold the sheet on the impression cylinder, and use the number cylinder to print the second number on the outer surface (one side) of the sheet, so that the second number can be printed on Two numbers are printed on one side of the sheet (see, for example, Patent Document 1 below). [0003] Patent Document 1: Japanese Patent Laid-Open Publication No. 2000-062134 [0004] Paten...
