Cots can be divided into: papermaking cots, printing cots, printing cots, hulling cots, metallurgy cots and oil printing cots, etc;
According to the surface shape, it can be divided into: flat roller and pattern rubber roller;
According to the material can be divided into: butyl rubber roller, nitrile rubber roller, polyurethane rubber roller and silicone rubber rubber roller.
Rubber roller is generally composed of outer rubber, hard rubber layer, metal core, roller neck and air vent. Its processing includes roller core sandblasting, bonding treatment, adhesive molding, cloth wrapping, wire winding, vulcanization of vulcanizing tank and surface processing. Cots are mainly used in papermaking, printing and dyeing, printing, grain processing, metallurgy, plastic processing, etc.
