This diagram is valid for all roll-up protection and represents:

• Type of terminal
• Direction of exit of the band
• Position of the terminal on the band

The band fastening terminals on the machine are made of steel or aluminium strips and angles drilled at the customers’ request.

Standard canister mounting systems

To select the most suitable mounting system, we recommend placing the fastening variants shown over the selected roller variant you have chosen, without turning the former.

• O = Horizontal roll-up protection
• F = Frontal roll-up protection
• V = Vertical roll-up protection

This diagram represents 2 options for applying the oil wiper to the canister.

SURE-SPRING® Mechanism
The P.E.I. Roll-up Cover equipped with the mechanism SURE-SPRING® represents the most advanced stage of technical innovation in the field of roll-up protections:

• Suitable for HIGH-SPEED work
• The multiple springs remain COAXIAL with each other
• The springs NEVER INTERSECT each other
• REDUCTION of the overall diameters
• ECCELLENT reliability
• SPEED of advancement up to 150 m / min
• ACCELERATION up to 2g
• Guarantee 2.000.000 movements
• SAFETY when anchoring the band to the tube because adhesive products are NOT used
• QUICK and EASY maintenance
• Also suitable for work environments with STRONG AGGRESSIVE chemicals

SURE-SPRING^® Mechanism HP VERSION
The SURE-SPRING^® HP winding mechanism is the answer to the elevated power required to wind up large size protective covers.
An optimal dimensioning of the springs guarantees the tensile force required for moving “J”-series apron covers.

The rotational movement of the tube with respect to the fixed central pin is obtained by means of a sliding toothed member.

This system allows you to compensate for the elongation of multiple springs by means of an axial displacement of the fixing of the springs themselves using a multi-start threaded pin.

This new system allows multiple springs to work with optimal structure, keeping the coils closed thanks to their sliding movement along the axis.

Mechanical fixing of the floor on the tube

It is the most reliable method to ensure the safety of anchoring the band on the tube.

SURE-SPRING® working diagram

• In the shutter roller n ° 1 (traditional system), the springs are fixed to the heads housed at the ends of the pin. In this execution, the springs are arranged, during winding or unwinding, in a typical helical configuration with obvious wear problems due to rubbing between the coils themselves, as well as between the coils and the central shaft.
• In the shutter roller n ° 2 (SURE-SPRING® system), the springs are fixed to a movable head which, during winding and unwinding, slides longitudinally, keeping the coils of the springs packed and concentric. This structure of the springs avoids most of the wear mentioned above, allowing much higher performance and a much longer operating life of the shutter roller.
