ABSTRACT:
A guide strip control device of pipe bending machine for controlling the transverse movement of a guide strip that is applied laterally against a pipe to be bent, which is held and moved longitudinally by a carriage. A first cylinder moves the guide strip over a considerable distance to disengage the pipe entirely from its gripping position and thus to allow the free passage of the carriage. A second cylinder moves the guide strip over a short distance so that the pipe is freed laterally but remains supported by a part of the guide strip.
