  • Principles of Operation

  • Critical Data

Calender rolls are heavy rolls used to emboss, press, or heat a material. Often two or more rolls are used together for a process. By circulating a heat transfer media such as hot oil through the rolls, the temperature on the outside surface, or face, of the roll can be precisely controlled. This type of HEAT system can be used to heat up and / or cool down the temperature of the product in contact with the roll.

Several different processes can be accomplished using rolls. Two rolls can work together to laminate two materials together. An embossing roll can impress a pattern to textiles, paper, or some other web-type product. Heavy rolls can be used to press and bond materials together, including laminates, plastic parts, and even metals. Rolls are used extensively for paper converting applications like putting a layer of foil on paper (as in a chewing gum wrapper).

Because of the wide variety of uses specific process data should be gathered, including:

  • Size (length and diameter), weight, and material of the roll itself
  • Details of the flow path for the heat transfer media through the roll
  • Information about the material being processed is important; speed, thickness, type of material(s)
  • Temperature profile required across face of the roll (critical for many applications, a thermal fluid system provides precise control).
