SURE-SPRING® mechanism
The P.E.I. patented design known as SURE-SPRING®  represents the most advanced level of technical innovation in the field of roll-up covers.

• Suitable for high speed operation
• The multiple springs remain coaxial
• Reduced overall diameters
• Advancement speeds of up to 150 m/min
• Acceleration of up to 2 g
• 2,000,000 movement guaranteed
• Secure attachment of the band to the tube, because no adhesive products are used
• Quick and easy maintenance
• Also suitable for use in work environments where strongly aggressive chemicals are applied.

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 rotary movement of the tube in relation to the fixed central shaft is transmitted by a sliding spline.

This system compensates for the elongation of the multiple springs by moving the spring mounting point axially along a threaded shaft.

This new system allows the multiple springs to work according to an ideal geometry, keeping their coils properly spaced.

This is the most reliable system for insuring a secure mechanical fastening between the band to the tube.

SURE-SPRING® operation diagram

• In Mechanism 1 (traditional system) the springs are rigidly attached to the fixed caps at the ends of the shaft. In this system the springs helically twist and snake while
  winding or unwinding, causing obvious problems of friction and wear between the coils as well as between the coils and the central shaft.
• In Mechanism 2 (SURE-SPRING® system) the springs are attached to a special moving cap, which slides lengthwise while winding and unwinding, keeping the spring coils packed and concentric at all times. This spring configuration avoids most of the wear mentioned above, allowing better performance and a much longer operating life-span for the spring mechanism.
