Will the end of the white paper cut by the roll cutting saw become mushy and black?

As the name suggests, paper roll cutting saws are primarily used to cut paper rolls for packaging and other purposes. However, there are some common issues that may arise during the process of cutting paper rolls, one of which is the discoloration of the cut white paper surface.

In many cases, paper roll cutting saws may cause the cut edge of the white paper roll to become blackened or discolored. This can be a frustrating problem, particularly when producing white packaging materials. The discoloration can be caused by a number of factors, including improper blade alignment, blade dullness, and excessive heat generated during the cutting process.

One of the primary causes of paper roll discoloration is the alignment of the blade. If the blade is not perfectly aligned with the paper roll, it can cause the paper fibers to tear or fray, leading to a rough or uneven cut. This can create more friction and heat, and result in charring or burning of the paper fibers.

Blade dullness is also a common cause of paper roll discoloration. Over time, the blade will become dull from continuous use, and can no longer efficiently cut through the fibers of the paper roll. As a result, the blade will begin to tear and fray the paper fibers, leading to discoloration of the paper surface.

Lastly, excessive heat generated during the cutting process can also lead to discoloration of the paper surface. This is particularly true when cutting white paper rolls, as the high levels of heat can cause the paper fibers to char and turn black.

Therefore, in order to avoid paper roll discoloration, it is important to ensure that your paper roll cutting saw is properly aligned and that your blade is sharp. Additionally, reducing the speed of the blade and decreasing the cutting pressure can also help to reduce heat generation, ultimately leading to a cleaner and more efficient cutting process.
