Hydraulic 4-Roller

plate bending machines

VRM

The Haeusler hydraulic 4-roller plate bending machine type is todays "state of the art" technology, the result of constant development and improve-ment combined with more than 50 years of Haeusler experience in the world of roll bending. Many of Haeusler's 4-roller plate bending machine developments over the years are now requested industry standards.

In 1965 Haeusler was the first to bring the hydraulic 4-roller plate bending machine on the market. A few years later Haeusler initiated the first hydraulic rotation drive of the top and bottom rolls.These with many other developments and a comprehensive after sales support, combined with the uncompro-mising quality, close customer project development and relations, has from the start made us the market leader in the world of 4-roller plate bending machine technology.The following pages give you an insight into the range of possibilities and advantages for our VRM 4-roller plate bending machine types

Cone rolling system

Due to the inclination of the bottom roller, the cone blank to be rolled is clamped and trans-ported by top and bottom rollers on the big radius. There is no firm contact between plate and rollers at the smaller radius and thus differences of circumferential speeds do not have to be compensated for. The thrust of the plate is

absorbed by a special cone bending shoe creating
