Press cylinders - Import export

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

The hydraulic hot presses have been dimensioned in such a way that they are able to exert and evenly distribute a specic pressure of at least 400 N/cm² on the product. Features, function The loader takes up the pressing batch at the transfer station. The previous nished board is removed from the press and the new press batch is transferred into it. The subsequent pressing time depends on the resin's reactivity, the selected pressure and the set temperature Advantages The press uses a multi-cylinder design that, with the pliant hot platens used, permits the specic pressure on the product to be set very precisely. Path-controlled press operation permits a cylinder movement that is technologically optimised with the loader’s and unloader’s cycle times tuned accordingly.

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.
