Abstract
In a rotary pipe bending machine in which the pipe is clamped against a rotary bend die by a clamp die and the two dies are rotated together while a rear section of the pipe is pressed by a pressure die, the clamp die is adjustably mounted for motion tangentially of the bend die. The clamp die can be driven between a first position in which it is spaced forwardly of the bend die axis and forwardly of the bend die, and a second position in which it is positioned substantially at a point of tangency between the pipe to be bent and the bend die. The position of the clamp die is chosen according to the length of the straight portion of the pipe between a previous bend and the point at which the next bend is to be made.
