Rubber covered rollers have different functions in sheet metal treatment machines including: towing, transport, pressure on the product and more. The surface, which is the area of contact with the treated product, can be coated with different materials including: silicone, hypalon, polyurethane, neoprene, EPDM, viton.
The transport rollers have the function of transporting the product that is the sheet. They are usually characterized by simple journals without transmission links.
The surface, which is the area of contact with the product, can be finished cylindrical, conical, concave or convex with turning or grinding (if necessary previously treated with hardening processes), subsequently different coatings can be made such as: thick chrome plating and grinding, non-stick coatings, silicone, hypalon, polyurethane, neoprene, EPDM, viton, zinc plating, painting.
The wringer rollers have the function of eliminating the chemical agent, liquid, in excess present on the sheet.

Cooling rollers, also called cooling calenders, are rollers that have the function of altering the temperature of a product which flows on their surface. The temperature differential is created thanks to the flow of a cold liquid inside the rollers.
This type of roller can be identified through different constructions: simple flow, double cross flow, with free gap, with spiral gap, with constant pitch spiral or with variable pitch spiral.
The surface, which is the area of contact with the product, can be maintained by a grinding finishing or coated. The possible coatings are: thick chrome plating and grinding, non-stick coating, carbide, ceramic.
