ALTEMA know-how for lagging handling drums
Cold bonding of rubber is generally used on “classic” drums. ALTEMA uses cold bonding for smooth, diamond-shaped rubber laggings with ceramic inserts.
The different stages of cold gluing :
- The surface of the conveyor drum is first prepared by shot blasting.
- After preparation, the drum is cleaned with solvent before the “primary metal” is applied.
- The conveyor drum lagging is then prepared for installation by cutting to size and cleaning all prepared surfaces.
- Next comes the gluing of the various elements, followed by the laying of the covering.
- The drum lagging is then struck/rolled to remove air residues and ensure perfect adhesion to the conveyor drum.

Profile types
Diamond
The universal lagging
Used on deflection and take up pulley. It is also suitable for head drums.
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.
Slide Lag
For high tensile forces
Its elastomer composition gives head or drive drums high tensile strength.
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 while being self-cleaning, preventing material build-up and misalignment.
The benefits of rubber lagging
- Bonding systems that make installing drum rubber easy, fast and tailored to your needs.
- The laggings protect the belt and significantly improve the conveyor’s overall performance, thus extending its service life.
- They ensure that rollers and drums rotate smoothly without clogging, thus maintaining and aligning the conveyor belt.
- Rubberized pulleys protect the belt by reducing slippage between belt and drums.
- They reduce the belt’s operating tension, thus reducing belt elongation.
- They reduce conveyor noise and vibration.

Other trimmings and preparation
Hot vulcanization
Vulcanization is a chemical process that gives the drum greater tensile strength, swelling and abrasion resistance, as well as greater elasticity.
SPECIAL RUBBERIZING
Laggings 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.
