The Pinch Cum Pyramid Principle

The Machine based on this principle combine the advantages of three roll pyramid type, three roll initial pinch type and four roll pinch type machines.

Highest degree of pre-bending can be achieved and only the smallest possible width of flat remains.
An error in pre-pinching can be corrected even after the shell is completed.

It can pre-pinch and roll the plate without removing the plate from machine after first insertion.

Inclined movement of bottom rolls provides wider bending pan as the plate thickness increases, and better grip in thinner plates.

Cone Bending

The Machines Has Inherent feature for conical bending without any extra attachments. The two bottom rolls are inclined by disengaging the dog clutch by lever fitted on the machine. Even Pre-pinching of cones can be done.
