Abstract
A pipe bending machine having two bending heads is endowed with two bending heads (9, 10), that each can move in the initial direction of pipe to be bent (12), each also being endowed with a bending tool that operates in a bending plane whose orientation can be modified. At least one of the bending heads (9, 10) can also move in a plane perpendicular to the initial direction of pipe (12) and holds clamping mechanism (27, 29) of the pipe, offset from the longitudinal axis of the head. In this way the head can be moved away from initial axis (11) of the pipe, the associated clamping mechanism (27, 29) in this case moving into such axis and being able to hold pipe (12) temporarily therein. This arrangement makes it possible to execute very closely-spaced bends in the median area of the pipe.
