1. The design structure of automatic chain paper pasting machine makes the backing paper easier to transport and locate, while the face paper needs to be treated in other ways. The backing paper is thicker, while the tissue paper is thinner or lighter, so more processing steps are needed in the design to ensure the transportation and positioning of the tissue paper.
2. The paper characteristics of backing paper and face paper are different. The backing paper is hard and rough, and the face paper is soft and smooth. These characteristics will affect the friction and stability of paper during transportation, because different treatment methods are needed to ensure the normal operation of paper.
