  • flexible quickly-changeable concepts provide short periods of time for reconfiguration
  • hard wear-resistant roller forming racks
  • accurate transmission of upper and lower drive rollers



Quickly-changeable cassettes and wheel with sensors


Blank strips supply device

  • dual uncoiler for quick change of material spools
  • rolls of material diameter is up to 2,000 mm, it provides long and continuous production

Material pre-heating device


  • material preheating temperature control to optimize filler curing time
  • rational energy-efficient pre-heating

High-precision roller forming stamps


  • geometry with tight tolerances and high-quality surfaces
  • manufactured with modern CNC machines
  • support system for profiles development
  • own department of testing and installation

Foam-filler unit

Foam-filler unit

  • reliable device for continuous operation in severe industrial environments
  • cleaning of mixing heads and nozzles is performed only during pauses in the production process, e.g. in the process of change of coils with material - No additional downtimes.

Solidification tunnel

  • exact dimensions of a tunnel are used to provide reliable hardening of the foam
  • controlled temperature in order to ensure consistent quality of foam


Block for profile flattening with quickly-changeable rolls assembly and location data reader

Perforation (punching) block


  • integrated into the production line, helps to avoid secondary and autonomous operations
  • accurate perforation on the basis of templates is performed due to rigorous direction of a profile and precise control system
  • optional: on/off button for performance of perforation in the manufacturing process


Foam solidification tunnel

Mobile block for cutting of a continuously moving material

  • Saw with a narrow cut, produced on the basis of a modern technology
  • Short cutting cycles - high speed production


Devices for cutting and packaging


  • Can be integrated into a variety of additional devices
