We manufacture pressure and feed rollers for moulding machines, feed devices and belt grinding machines according to drawings or samples completely ready for installation. The choice of the roller coating, the smooth or grooved design and the most suitable degree of hardness must be determined for each customer. We will be happy to advise you by telephone or at your site regarding a high-quality and cost-effective design of pressure and feed rollers.
Weinig rolls consist of a core of aluminium or grey cast iron. In addition to the polyurethane materials that have long been proven in the wood processing industry, the elastomer Vulkollan® is mainly used for the coating. The locating bores of the core are designed as parallel keyways or with three secondary holes.
The Weinig rolls are mainly coated with the elastomer Vulkollan® patented by Bayer. Its outstanding product properties are characterised in particular by outstanding tear and tear propagation resistance under the highest mechanical stress, extremely low abrasion even on rough contact surfaces and impressive dimensional stability. Like polyurethane materials, Vulkollan® also has good resistance to solvents, glues, gasoline, mineral oils, paints and greases.
