Heat transfer and chill rolls, polishing rolls

Heat transfer and chill rolls

are used for heating, cooling and smoothing of all types of sheet products.

“The more exact the temperature control and the shape of the rolls,
the better the properties and the quality of the product sheet.”

Polishing rolls

are used for smoothing all types of web-shaped products.

“The higher the actual line load,
the more necessary the dimensional stiffness of the polishing roll.”
