  • Apparatus for forming a pipe from a sheet metal plate
    Patent number: 5367897
    Abstract: A plate rolling apparatus, for rolling a plate to form a pipe which may be tapered, a gripper rib (14) on the mandrel (11) for receiving the edge of a flat plate. The mandrel (11) being mounted between support frame ends (24, 25) and on a single pressure roller (15) mounted beneath the mandrel (11) and adapted to contact the surface of the plate and apply a squeezing force against the plate and mandrel (11) during a rolling operation, the pressure roll (15) being laterally movable relative to the center-line of the mandrel depending upon the location of the gripper rib (14) in the region of the roller (15) so as not to foul the gripper rib (14) yet applying said squeezing force to said plate as required. A mandrel (11) having an adjustable taper angle is disclosed as an adjustable mandrel support member (2, 25) and mandrel journal (26) to accommodate variable mandrel diameters and angles or taper.

  • Plate bending method
    Patent number: 4428215
    Abstract: There is disclosed a method of rolling flat plate using a cylindrical mandrel and a plate gripper to form a pipe having a low pipe diameter to plate thickness ratio by forming a notch or recess in the plate edge to be gripped so that the combined radial dimension of the notched plate edge and gripper is no greater than the plate thickness.
