Abstract

657,187. Angular bending. ETABLISSEMENTS GRIMAR. Feb. 9, 1949, No. 3556. Convention date, April 1, 1948. [Class 83 (iv)] A hydraulically-operated bending-machine has a central ram 2 connected by links 3 to cranks 4 on a shaft 6 which carries cranks 10 operating spaced pressure members 9 for a bending-beam 7. The rigidity of the shaft 6 ensures simultaneous actuation of the members 9. In a modification with two hydraulic cylinders the beam operating cranks are crossconnected by a shaft.
