Faccin Plate Rolls Planetary Swing Arms 4HEP

4 Rolls Double Pinch Planetary Guides

The 4HEP series of 4-roll synchronized bending rolls is the latest design evolution developed by Faccin and tested by the most demanding operators in extreme environments for over 25 years. It combines power, reliability and precision in an exclusive package that makes it the state of the art in modern plate rolls.

A closed loop structure guarantees superior rolling quality and high repeatability of the products roundness that together with the traditional ultra-wide drop end ensure maximum rigidity of the machine against high longitudinal and traverse forces.

The traditional linear RGS design of the pinching roll guarantees higher pinch forces for superior quality pre-bending. The pinch roll is supported by 4 independent bearings (2 on each side) and the bearing housing is two times larger for better lateral load absorption and guiding.

The HFS system features an external mounting of the pivoting lateral hydraulic cylinders, fixed in their highest end as standard configuration on all medium and large sizes of 4HEP to ensure a greater closeness of the bending force application points.

The 4HEP innovative design optimizes the entire rolling cycle, working in one direction and in one pass, ensuring extreme safety and the capability of being handled totally by a single operator.

SIEMENS numerical control systems are available in all versions of 4HEP series for the precise control of roller conveyors, automatic loading and unloading systems in the creation of a fully-automatic line.

4HEP bending rolls with exclusive Siemens CNC - designed and built by Faccin - are the most reliable and modern solution available amongst all rolling machines with planetary technology in the market today. The most reasonable investment for high productivity requirements when rolling plates from less than 1m and up to 10m with thickness 5 to 150 mm.
