Method and an apparatus for the parallel displacement of a material web
摘要:
A method and an apparatus for the parallel displacement of a material web (1) are disclosed, in that the material web (1) is, between two driven bending rollers (6,8), caused to form a freely depending bight or loop (11) whose lower end is read-off by a sensing device (12). The sensing device (12) controls the speed of the first bending roller (6), while the second bending roller (8) is driven at constant speed.
