HELLER HYDRAULIC 4 ROLL
Whether you are a job shop or manufacturer, the Heller 4 Roll is the best solution. Every machine, size for
size, can roll 30% tighter diameters than any type roll and 30% thinner material than 3 roll double pinch machines. These features,
combined with the advanced technology incorporated in all aspects of the Heller Roll, make it up to 300% more efficient than 3 roll
machines. The following graphs explain why.
![[Bullet]](images/RollingCapability.jpg)
By using exclusive planetary guides: available on Heller Rolls, we are able to keep approximately 50% more area of the plate under bend pressure
during the rolling operation, thereby allowing the Heller
Rolls to roll down to 1.1 the upper roll diameter. This
allows Heller Rolls to have a 30% advantage on tight
diameters.

Heller Roll maintains a mechanical finite parallelism through our exclusive torsion bar system which allows the machine to be adjusted to its full conical tilt and ![[Bullet]](images/hellertorsionbar.jpg)
back to parallel in only 5 seconds for the life of the machine.![[Bullet]](images/conerolling.jpg)
Cone rolling: through exclusive technology, Heller Rolls can develop cones as easily as competitive machines can develop cylinders. And it eliminates scarring on the surface of shell or roll and also eliminates, in most cases, the need for grinding the lamination (bullnosing) on the minor diameter edge.![[Bullet]](images/h4rollmodel42510.jpg)
