ABSTRACT:
The pipe-bending machine comprises two bending heads (11,12) being configured so as to be mirror-inverted with respect to each other and projecting in cantilever-like manner from a machine frame (10). A cross slide (26) supporting the pipe holding device (25) is displaceable on the machine frame (10). The first bending of the pipe (17) is performed in a first bending head (12). Then, the pipe holding device (29) is displaced to the second bending head (11) where the second bending operation is performed. Thus, several bending operations can be effected successively without there being a need to reclamp the pipe.
