Why Are Paper Stacks Not Aligned After Sheeting?
Many paper converters have faced this problem:
The machine is running normally.
The sheet size meets the requirement.
But after cutting, the finished paper stack is not neat.
Some sheets move slightly.
The edges are not aligned.
Workers need to manually adjust the stack before packing.
For products like A4 copy paper, printing paper, and packaging paper, this small problem can affect packing efficiency and final product quality.
The reason is not always the cutting knife.
During roll paper sheeting, the paper needs to stay in a stable position from the beginning. If the paper web moves slightly before cutting, the deviation will accumulate after thousands of sheets, making the final stack uneven.
One common reason is unstable paper tension.
During high-speed production, the paper moves continuously from the roll to the cutting section. If the tension on both sides is different, the paper may shift during feeding. Thin paper, coated paper, and high-speed A4 production are especially sensitive to this issue.
Another factor is the feeding and guiding system. Without stable paper control, even a small deviation during transportation can affect the final stacking quality.
At CHM Machinery, we focus on the complete sheeting process, not only the cutting unit.
To improve sheet alignment, CHM machines are equipped with:
Stable roll feeding system
to keep the paper entering the machine smoothly.
Automatic web guiding system
to reduce paper deviation during production.
Precision feeding structure
to maintain consistent paper movement before cutting.
Optimized delivery and stacking system
to ensure finished sheets are collected neatly.
Different paper grades require different solutions.
A good paper sheeter is not only about cutting speed.
It is about making every sheet come out straight, accurate, and consistent.
