SHAPING APPARATUS WITH INTERCHANGEABLE PLATES

摘要

The apparatus has a processing roller (3) with a support roll on which an interchangeable plate (3b) is connected. A regulation module (7) has a take-up roller to control displacement and speed of a sheet (2) at an upstream of the roller (3). A guide roll (9) exerts a positive guidance on a loop (8) of the sheet formed between two cylinders based on displacement function, which is a function of a loop length during operation.
