Dancer rollers

Dancer roller made of CFRP/GRP and aluminium

As a leading manufacturer of rollers, we offer you dancer rollers made of CFRP, GFP and aluminium. They are an important component for regulating material tension in production lines and are widely used in conveyor technology – particularly for processing web materials like paper, film, textiles, and metal strips. Our dancer rollers significantly contribute to preventing material tears and stretches, making them crucial for quality assurance and increased production efficiency.

Tension regulation & precise material guidance for optimum product quality

Dancer rollers from INOMETA are widely used in a variety of industries – virtually anywhere web materials are transported. This includes packaging, printing, plastics, textiles, film, and paper manufacturing. They provide uniform tension when processing substrates such as plastic films and paper to ensure production quality.

INOMETA offers dancer rollers in various designs for these different applications:

  • Dancer rollers with weight force, which generate constant tension through gravity.
  • Spring-loaded dancer rollers use mechanical springs to regulate the tension.
  • Pneumatic dancer rollers to adjust the material tension with compressed air.
  • Electronically controlled dancer rollers provide the highest precision by using sensors and actuators to monitor and adjust tension in real time.

Controlling the material tension in production lines is a central task of our dancer rollers – they enable precise tension control by reacting dynamically to changes in the material feed. This ensures that the material tension remains constant, which makes a decisive contribution to preventing material cracks and expansion. This not only improves the quality of the end product, but also reduces rejects and production downtime.
The dancer rollers made of CFRP, GRP and aluminium are specially developed and manufactured to meet the high demands of modern production processes. With their advanced technology and high-quality materials, these rollers make a significant contribution to improving production quality and efficiency.

Dancer rollers made of aluminium & CFRP/GRP – all advantages at a glance

INOMETA dancer rollers stand out for their lightweight design and smooth operation, making them the ideal choice for high-demand production lines. They deliver precise web tension control, effectively preventing material tears, wrinkles, and other issues. This translates to enhanced product quality and increased production efficiency. The maximum load capacity of the dancer rollers varies depending on the model and application, ensuring they can handle the specific requirements of your industry.
A correctly designed dancer system meets the given requirements and avoids other common processing problems – interlocking, star-shaped cracks or uneven webs, guaranteeing impeccable tension control.
A significant benefit of dancer control lies in the increased storage capacity within the web, achieved by extending its length in the machine direction. This extended length enables the web to better absorb tension fluctuations caused by various factors, such as uneven rollers. By absorbing these tension fluctuations within the appropriate zones, the web tension is maintained evenly after the dancer, resulting in mechanical stability during the processing of large rolls during the unwinding and winding processes.

The advantages of INOMETA dancer rollers include

  • Low weight and smooth running
  • Precise control of the web tension
  • Improved product quality
  • Increased production efficiency
  • Maintenance-free bearings
  • Lowest starting torques
  • Tight shape and bearing tolerance
  • Precise surface finishes from smooth to rough surfaces
  • Customized configuration of dancer rollers, including sizes, coatings, materials
  • Use of high-quality materials for long running times, high rigidity and high wear resistance
  • Low shrinkage behavior and good damping properties
  • Uniform and precise guidance of the substrate
