PROBLEM TO BE SOLVED: To provide a device that can adjust a force to fix a lateral perforation blade in a lateral perforation gullet of a lateral perforation body without depending on a sense of a worker, and can fix the lateral perforation blade to the lateral perforation gullet of the lateral perforation body without using a bolt.SOLUTION: A lateral perforation blade fixing device 1 shown in Fig. 1 includes a lateral perforation body 2 for fixing a lateral perforation blade 3 to machine a lateral perforation 7a on the continuous paper 7, a compressor 5 for supplying air to the lateral perforation body 2, and a regulator 4 for controlling an air pressure of the air supplied to the lateral perforation body 2 in a set pressure. The lateral perforation blade 3 is fixed in a lateral perforation gullet 20 by the air pressure in a plurality of cavities 21 formed in the side wall of the lateral perforation gullet 20 of the lateral perforation body 2.SELECTED DRAWING: Figure 1 |
