Description

Flattening assembly for film folds Technical Field The utility model relates to the technical field of film processing equipment, in particular to a flattening assembly for film folds. Background During the production and processing of film-like materials, the film is typically transported in a high-speed continuous manner in an apparatus and wound into rolls. In order to ensure product quality, the film must remain flat and have uniform tension during operation. However, the film is often subject to tension fluctuation during transmission and winding due to fluctuation of working conditions, disturbance of equipment or factors of the film, so that the running path is deviated, and quality problems such as wrinkling, folding, irregular winding and the like are generated.
