The cross cutting mechanism in paper towel production is a mechanical device used to cut continuous large rolls of paper towel into the desired size (such as single sheet, small package or multi-layer stacked pile). This process occurs in the later stage of paper towel production. After the paper is completely dried and rolled into a large roll, it needs to be cut into a convenient size by a cross cutting machine.
