A METHOD AND AN APPARATUS FOR THE PARALLEL DISPLACEMENT OF AMATERIAL WEB |
| 摘要 |
The invention relates to a method and an apparatus for the parallel displacement of a material web (1) 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 secondbending roller (8) is driven at constant speed.
