Rolls and rollers in the printing industry

Optimum wettability of the liquid-carrying rolls is very important in the printing industry. Precisely-defined amounts of liquid must be carried. TOPOCROM® coated printing rolls can be precisely wetted and are resistant to aggressive media (printing inks, detergents).

Feed rolls in the sheet metal industry

TOPOCROM® coated rolls ensure ideal feeding behaviour in sheet metal belts which have been treated with oil or dry-film lubricant. At the same time, they achieve longer service life.

TOPOCROM® surface is ideal for the sheet metal feed.

The adjustable topography or roughness of the coating on the feed rolls provides friction characteristics (grip), which have been well proven in the sheet metal processing industry. Leading manufacturers of sheet metal feeding machines have their rolls coated with TOPOCROM®. Important advantages
  • Optimum grip
  • Ideal feeding behaviour in sheet metal belts, which have been treated with oil or dry-film lubricant
  • Longer service life
