ABSTRACT:
A device for generating curved pipe portions (38, 40) bent alternately in opposite senses in a continuously supplied linear pipe (18), particularly for generating a pipe coil, comprises a machine table provided with two bending rolls (12, 13) having rotational axes (15, 16) extending at a fixed mutual distance and parallel to each other. The bending rolls (12, 13) have their peripheries formed with grooves for receiving the pipe (18) which are adapted to the cross-section of the pipe (18). Further, the device is provided with a bending drive. One bending roll has a rotational axis fixed in position relative to the machine table whereas the other bending roll is pivotable by said bending drive about the bending roll having the fixed rotationai axis, thereby bending a curved pipe portion (38, 40) of the pipe (18). For obtaining a particularly simple construction of the device and allow easy handling, it is provided that, in alternate fashion, a respective one of the rotational axes (15, 16) can be fixed in position while the respective other rotational axis (15, 16 ) can be coupled with the bending drive. The bending drive is rotatable alternately in opposite senses.
