Abstract
A rotary draw bending machine employs a stack of bending dies 22 of different curvatures, forming part of a bend head 18 that is entirely mounted on the forward end of the machine bed 10 for bi-directional lateral and vertical motion so that without changing the position of the centerline of the pipe 16 to be bent, it may be formed by bend dies of different curvature. The entire bend head 18 is shiftable laterally to enable the bend dies to clear the pipe 16 as the dies move vertically to position another die. A single pressure die 20, which is mounted on the movable bend head 18, is mounted for vertical movement relative to the bend head so that it can be positioned in alignment with the pipe.
