Experience in cutting off offset printing press paper

When the operator cuts off the printing paper for the offset printing press, he or she often needs to remove the large paper (the finished paper that has been opened) and cut several rounds in order to meet the requirements. In particular, it is necessary to cut a few times when cutting open short edges, and labor intensity is great. Later, in the production practice, the operator found that the short-cut edge was completed at one time.

When the cropping pair is open, after the long side crop is completed, when cutting the first short side, do not determine the rules, just push the paper to clean the raw edge light, and then press the desired paper size. A burr is marked, and light is cut after pushing. Afterwards, do not move the guide screw, use the main cutter to draw a line on the platen screw handle and the workbench, and specify the specifications for the next time.

When you cut a ream, you need to shake it back half a turn. After cutting a short edge lightwise, when the light is cut to the other short side, push the paper into the machine and rotate the handle clockwise to make the machine match with the handle mark and then cut the paper. Cutting other sizes of paper can be analogized as well.
