The PBM DP arrangement 3 Roll Pyramid Type Hydro-MechanicalPlate Bending are planned with twofold side pre-squeezing course of action. Theone of a kind outline allows the pre-squeezing of employment by both baserolls; subsequently the occupation is finished in single operation. Thiscomponent makes the machine more gainful and reasonable for taking care ofoverwhelming employments. The top roller is settled and pre-pinching by bothbase rolls are through pressure driven barrels. The job is bolstered from oneend to complete pre-squeezing and whole shell is moved to wanted curve span.Flip side pre-squeezing is done by second base move to finish the shell. Thecomplete shell is set up in single operation.
