Bending machine with two rolls and method of round bending plates

摘要

In a two-roll rounding machine (1) in addition to the pressure-elastic guiding roll (3, 5) and the compressively rigid rounding roll (6) compressively elastic rolls (8, 10; 11, 13) are provided which a rounding function and a supporting function for the rotary roller 6 to have. The remaining rollers 8 and 11 can be further supported by a support roll (14). In this way, a rolling machine is provided which has very good lap properties even with small rounding diameters.
