Application: Light power transmission and conveyingRubber qualities: CR, NBR, EPDM, XNBR, SI, NR
Very smoothrunning, low shaft load and excellent resistance against abrasion.
CRELAST® flat belts are elastic - no tensile carcass - and endless cured according to our unique truly endless process.The precise manufacturing length L0 results in the desired tension force for any low power transmission and/or exact conveying application.The low shaft load and the fully elastic belt allows small and fixed axes (no tensioning device needed) which is preferred in the apparatus engineering.For conveying and feeding of "paper" we have developed our EC-flat belt types, made of natural rubber (NR)- similar to LINATEX. Natural rubber guarantees a constant high friction coefficient and excellent resistance against abrasion.With the various rubber qualities at our disposal, we design the belts exactly according your requirements (FDA, ATEX, RAL-colour, etc.). Please do not hesitate to call us.
Application: Feeding and conveyingRubber qualities: CR, NBR, EPDM, XNBR, SI, NR
Exceptional high running time and easy fitting.
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).Frama (ASCOM), Quadient (Neopost), Bluecrest (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.
Application: Winders for tubes and cansRubber qualities: CR, NBR
Very resistant against abrasion, antistatic.
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.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.
Application: Cut, strip and crimp machinesRubber qualities: NR, CR, PUR, NBR
Very resistant against abrasion and the best coefficient of friction.
These truly endless haul-off belts "Wire feeder" are used for assembling all kinds of cables and wires, i.e. for cut, strip and crimp machines.Depending on the required pull-off force and wear resistance as well as the quality of the processed cables and wires, 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 performances.
Application: Extrusion plants for pipes, hoses and profilesRubber qualities: NR, CR, NBR
These truly endless haul-off belts "Caterpillar" are used in all kinds of extruders, e.g. in caterpillar haul-offs for 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 performances.
Application: Paper and cardboard feeding, as well as VFFS machines.Rubber qualities: NR, EPDM, SI
Our truly endless haul-off belts “VFFS” are used by our customers for various feeders, sorters as well as VFFS units. The extreme reliability and durability of all our products are an advantage for the usage of our haul-off belts in machines of i.e. Bosch, Ilapak or Rovema.
These truly endless belts are inter alia characterized by a high-quality rubber grade as well as our possibilities in customizing belts.
You can choose the rubber grade that fits to your application. Furthermore we can improve our haul-off belts through various millings or grooves according to your needs.
Due to these characteristics, you will receive a high coefficient of friction, long machine running times and highest quality.
