Conveyor drum lagging for applications with very high tensile forces
The Slide Lag® coating system is a drum lagging system that uses welded slides on the drum surface as a base for the lagging. The covering consists of vulcanized rubber on a steel support that slides under the rails. Slide Lag® lagging does not require drum or belt disassembly, reducing handling and transport times and making it more economical.
Slidelag® lagging is applied by a high-pressure hot vulcanization process, using thick steel plates designed to fit each drum diameter. Its elastomer composition enables the head or drive drum to achieve high tensile strength. This lagging can be replaced without removing the drum from the conveyor.
In addition, EDGE-CROWN elements can be used to quickly transform the profile of the drums to obtain the crowning. This crowning, with a 4mm radius, centers the belt.

Other profile types
Losange
The universal lagging
Used on deflection and take up pulley. It is also suitable for head pulley.
Ceramics
The high-adhesion lagging
Effective in humid environments to prevent slipping on the conveyor belt.
Smooth
Protective lagging
For drums that don’t drive the belt, to extend their service life.
Pulley bars
Anti-skid lagging for large drums
Ruggedly designed, the anti-skid bars are made of wear-resistant rubber for long life.
Griplag
For tough conditions
The Griplag prevents slippage and is self-cleaning, preventing material build-up and misalignment.
VARIOUS FILLINGS AND PREPARATIONS
Hot vulcanization
Vulcanization is a chemical process that gives the drum greater tensile strength, swelling, abrasion resistance and elasticity.
Cold rubberizing
Cold rubber bonding is generally used on "classic" drums for rubber coatings with smooth, diamond-shaped ceramic inserts.
SPECIAL RUBBERIZING
Coatings such as Slide Lag, Pulleybars or Griplag are applied to drums and pulleys by mechanical assembly.
Shot-blasting
All coated drums are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the drum.
