Roll-up covers without canister

The PEI roll-up covers without canister are unique in their design and customisation for the user. The reliability of Roll-up Covers without canister guarantees up to 1,000,000 movements, thanks to the return motor equipped with multiple springs, which is reliable and operates with very high forward speed.

Mechanism

SURE-SPRING®

Roll-up covers without canister

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® HP VERSION

Roll-up covers without canister

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

Translation of motion

Roll-up covers without canister

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.

Innovative characteristics

Roll-up covers without canister

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

Fastening

Roll-up covers without canister

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

Scheme

Roll-up covers without canister

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.
CERAMIX Band

CERAMIX

CERAMIX Band

Aerospace technology in machine tools: a potent and cost-effective innovation

• Band material covered by a high ceramic polymer coating.
• Highly resistant against the impact of hot shavings during dry-working.
• It is an excellent abrasion resistance and shear strength and is recommended for the use of mineral oils.
• CERAMIX band material has a thickness of 1,8 mm and weighs 2 kg/sqm.
• It is antistatic.

This kind of band can be installed on any P.E.I. roll-up cover with mechanisms  from 70 mm tube diameter

CERAMIX LIGHT Band

Identical resistance at half the weight

• CERAMIX LIGHT offers all the characteristics of CERAMIX but at a thickness of 0,9 mm and 1 kg weight per sqm.
• Antistatic.
• Suitable for roll-up covers with mechanisms from 20 mm tube diameter.
