Calender rollers

Calender rollers made of CFRP and aluminium

Calender rollers compact or smooth material webs between two or more rollers under high line pressure, thereby determining the thickness and surface quality of the material. INOMETA manufactures calender rollers from CFRP and aluminium for applications in the paper, textile and packaging industries as well as for the calendering of battery electrodes.

Precise adjustment of the roller gap enables accurate thickness control and therefore uniform material thickness. The surface structure, whether smooth, matt or textured, is individually adapted to the respective application. The rollers are also designed for stable processing at high temperatures, so that the quality of the end product remains consistent under demanding production conditions.

Calender rollers for different industry requirements

The right calender roller depends on the material being processed, the pressure requirements, the desired surface finish and the production conditions. INOMETA designs its rollers accordingly for each industry.

Typical areas of application:

  • Paper industry (compaction, reduced porosity, uniform thickness and surface)
  • Textile industry (smoothing and coating of textiles, production of artificial leather)
  • Packaging industry (film packaging, coating of cardboard)
  • Plastics industry
  • Printing industry
  • Metal processing
  • Battery cell manufacturing (calendering of electrodes), see calender rollers in battery manufacturing
