The HEVALOID®-Feeder belts are made of high quality natural rubber (NR) – similar to LINATEX. These specially developed rubber quality guarantee a constant high friction and excellent resistance against abrasion.

The following approved belt types are used:
 

• ECT 06/ ECG 06 - length-stable (NR rubber with Polyester carcass)
• EC - fully elastic (NR rubber only)
• CR/EC - elastic (Two-layer belt with NR rubber on top)
• SE semi-elastic (with rhombic pattern)

For years, these truly endless belts convince customers in all kind of folder/gluer machines as well as in letter sorting plants.

The truly endless - no splice or seam - production results in very reliable, high flexible and perfect running belts.

Endless cured roll and friction covers convince due to their precise and homogenous surface, exceptional high running time and easyfitting (no glue needed due to sleeve technology).

ASCOM, Neopost, PB, etc. are taking the advantage of our reliable and most durable friction covers i.e. in there high performance inserters, folders, feeders and franking machines.

The EC red-quality - as well as all our other rubber qualities - are cured and processed exactly according to your desire.

The truly endless - no splice or seam - production results in very reliable, high flexible and perfect running belts.

HEVALOID®-tube winder belts consist of an endless woven polyester carcass coated with synthetic rubber. These truly endless belts have been successfully used for years in tube winder machines as well as in cater pillar units.

The production of truly endless belts - no splice or seam - results in very length-stable, high flexible and high performing belts.

The black chloroprene rubber is very resistant against abrasion, antistatic and results in a high running time.
The blue nitrile rubber is specially designed for non-marking applications.

The HEVALOID®-quality guarantees you a precise tube winding, a reliable stable feed and extremely high running time.

HEVALOID®- Haul-off belts
These endless haul-off belts are used in all kinds of extruders, e.g. in caterpillar haul-offs for cables, wires, pipes, hoses, profiles, etc.

Depending on the required pull-off force and wear resistance, a range of soft to very hard rubber qualities can be used (40 – 75 ShA).

We also coat your - timing and Poly-V belts endlessly - without seam or splice for the toughest demands and outstanding performance.
