Tensioning Systems -

Design and production of press-systems for the rubber industry is one major core competences of Siempelkamp More than 100 years of experience in rubber press lines More than 100 years ago, we put in operation the first conveyor belt press on the market. Only 20 years later, the first large vulcanizing press with a closed frame construction went successfully in operation. Even today, our presses and systems for the rubber industry have unqiue advantages: Durability, speed, high availability and efficiency, which are the most important arguments for our customers to choose a Siempelkamp plant. Proven technology that is trusted in the rubber industry With our broad expertise in the fields of rubber processing industry, we are the world market leader for steel cord and conveyor belt presses. A large part of the conveyor belts used around the world are manufactured on our equipment. Despite heavy loads, these conveyor belts always have to have best straight-running stability.

One of Siempelkamp’s core competences is the design and manufacture of presses for the rubber industry. With our expertise in this eld we are the world’s number one in steel-cord and conveyor-belt presses with many of the conveyor belts used around the world being manufactured on our equipment. Despite heavy loads, these conveyor belts always have to have best straightrunning stability. Siempelkamp's excellent manufacturing and high-quality plants are eld proven. Services Single-source supplier Uniform pre-tensioning of the individual steel cables Best pressure distribution in our vulcanising presses Cable clamping and tensioning device with a heavy clamp Compactor lorry with pre-press Pull-roll stand Reeling elements Advantages Excellent thickness tolerances due to multi-cylinder press without requiring press bolsters Safe vulcanizing process for various belt widths by controllable pressure distribution Transparent and controllable production process

For the production of conveyor belts with steel-cord or fabric layers, Siempelkamp oers a multi-cylinder down-stroke press including 2-track production. Conveyor belts having a width of up to 3,200 mm and a thickness of up to 50 mm can be manufactured at a pressure of 400 N/m2. To this end, Siempelkamp's multi-cylinder presses provide a pressure distribution previously unattainable with hydraulic-mechanical press systems. In addition, the thickness tolerances of the conveyor belts could be reduced here compared to traditional press concepts. Services Conveyor belt thickness starting at 5 mm Optimal pressure distribution due to our multi-cylinder concept Material reduction by eliminating the hot platen insulation Stable press gap parallelism High safety standards Advantages Improved process safety Low material and production costs due to reduced thickness tolerances Minimal foundation requirements Ease of maintenance and long service life

Siempelkamp’s steel-cord conveyor belt presses distinguish by an innovative steel-cord tensioning concept: the controlled steel-cord tension distribution system increases production safety and improves product quality. The electromotive tensioning system, which is individually controlled and installed directly in the creel with integrated measuring and control functions, allows a 100%-control over the actual steel-cord tension distribution. The exact quality reporting enables our customers to optimize the production, hence the product’s quality. The new concept replaces the xed-nger comb used in previous systems with a roller comb. The friction between comb and steel cables is thus eliminated. Consequently, the abrasive wear on the galvanized steel cables is reduced. Unlike the traditional concept, the new roller comb prevents any variations in tension distribution.
