A lagging for every application
Conveyor drum lagging
The role of the lagging on a conveyor drum depends on its function on the conveyor, its area of application and the external conditions.
The drum lagging can be used to increase adhesion and the coefficient of friction with the conveyor belt. It can also be used as a wear layer to preserve the drum. Last but not least, it minimizes the risk of slippage, ensuring smooth conveyor operation. This rubber lagging is also known as the lining.
ALTEMA is able to cover the drums and pulleys manufactured in its workshops with rubber drum lagging of all thicknesses and hardnesses. Different types of drum lagging are available to meet the requirements of the drum’s position on the conveyor, the material being conveyed and the environment in which it will be operating:
- ceramic lagging
- rubber lagging
- diamond lagging
- Anti-Caking
- anti-abrasion
- food-grade (FDA white or EU1935/2004)
- anti-grease or ISO 284 / 340.
Drum lagging is applied by cold bonding or hot vulcanization, depending on the application.

Profile types
Diamond
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.
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 and is 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 lagging 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 conveyor noise and vibration.

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.
