Technical Field

[0001] The utility model relates to the technical field of book and periodical folding machines, in particular to a folding and anti-cornering device for book and periodical folding machines. Background Art

[0002] When the book folding machine is folding at high speed, the paper tape is hooked by the hook. At this time, the paper tape is not cut and has a certain tension, so that the paper tape can be tightly wrapped around the outer surface of the hook roller. When the paper tape wrapped around the hook roller reaches half the circumference of the roller, it is cut. At this time, the paper tape has no tension. As the roller rotates at high speed, the centrifugal force and airflow generated by it cause the paper tape to flutter irregularly, which will cause corner folding during the folding process.
