EPR Pre-rollers

Pre-rollers provide economical and safe side-changing of your dies. Easier loading, while minimizing the risks.
A forklift or crane loads the die onto the pre-rollers. The die moves over the pre-rollers from the front of the press, past the end stops, onto the bolster.

A set of pre-rollers makes it very simple to push in and pull out a die of vertical presses. It also allows the use of a forklift truck or a crane to remove and load the die.

The EAS pre-rollers extend the press bed so the die transfer is done quick and safe.
Designed for vertical presses, pre‑rollers are always used as a pair. The size of the pre-rollers depends on the weight and dimension of the die.

Easy to install, both on new as on existing presses.

EAS offers you the best-fitted solution, combining our experience with your needs. From a single die change product to a complete automated concept, we are your turnkey supplier.

Die lifters

Typical setup for moving the die into the press is the combination of die lifters and a pre roller set. The die can be placed on the pre-roller in front of the press. From there the die can be moved easily over the rollers of the pre roller and die lifter into the press.

Minimize the force needed to position your dies – Die lifters smoothen movement and positioning on or out of the press. Depending on die weight, rolling is done by just a single ball, multidirectional ball bearings, or cylindrical roller systems for inline movement.

Die change car

Big dies require added muscle to ensure safe, accurate and efficient transfer. A die change car is the ideal choice! Drive, lift and transfer your dies manually, electric, by a rail guided or air floating cart.

Die change table

The transfer process can be automated even further with a rail guided die change car or table. These efficient solutions are equipped with positioning devices and the push/pull system is adapted to your requirements.
