The reason why the bottom paper is wrinkled when the paper tube is made

The reason why the bottom paper is wrinkled when the paper tube is made：

There are three main reasons:

1. The width of the separation paper is not appropriate. It's too wide. For example, the normal one is 10.8-11.2cm, and one with a width greater than 11.4 will cause this phenomenon.

2. The paper feed angle is too small, resulting in too much overlap of several sheets of paper inside. You can adjust the paper feed angle appropriately.

In fact, these two are for one reason, that is, they overlap too much.

3. The shaft is worn.
