The printed paper is folded by a folding machine and can then be bound, resulting in a printed material in the form of a book or magazine. A user friend inquired about the reason for the phenomenon of using a folding machine with double sheets. What is the problem? Below, the editor will introduce it to you.
Firstly, distinguish whether the folding machine you are using is a roller type or an air suction type.
1. The roller type itself is prone to double sheets. The solution is to fully loosen the paper before placing it, put it less and more frequently when placing it, reduce the pressure on the roller, and replace it with a new roller and rubber pad.
2. The suction folding machine produces double sheets mainly due to poor adjustment of the blowing and suction air. Solution: Fully loosen the paper before placing it; Reduce the amount of air blowing appropriately, but ensure that 8-10 sheets of the surface are blown open. Reduce the suction air appropriately, increase the distance between the surface of the paper stack and the suction nozzle or suction wheel appropriately, and increase the distance for the separation paper to penetrate.
If you also experience the phenomenon of double folding when using the folding machine, you can check the equipment according to the above introduction and make timely corrections.
