Abstract
1399926 Bending metal MITSUBISHI JUKOGYO KK 5 Sept 1972 [8 Sept 1971] 41112/72 Heading B3E Metal plates for use in the construction of spherical pressure vessels are bent on apparatus comprising mating convex and concave rolls 1, 2, and further concave rolls 3, 4 displaceable in a direction to bend the plate. In use, a plate is fed through rolls 1, 2 to the left, and at a certain point in its passage roll 4 is raised to produce a further bend in the plate. The feed is then reversed, and the plate moved to the right, roll 3 being raised, this cycle being repeated as desired. Each roll may be divided by planes normal to its axis into components some of which are driven and some rotate freely. The roll surfaces may be covered with hard rubber.
