[0002] EVA is a thermosetting adhesive film used to be placed between laminated glass. EVA is the abbreviation of Polyethylenevinylacetate, a copolymer of polyethylene and polyvinyl acetate. Due to the superiority of EVA film in adhesion, durability, optical properties, etc., it is increasingly widely used in current components and various optical products.

[0003] EVA film is shipped in the form of a roll and needs to be cut. Therefore, a variety of automatic cutting machines for automatically cutting EVA film have been designed to automatically discharge and cut the EVA film of the required length, such as an EVA film automatic cutting and collecting machine disclosed in patent application number 201911059963.8. However, the existing machines can only automatically cut the EVA film to a set length, but more precise dimensions are required to put it on the glass.
