Type CG / CGV (Banana)

Fixed deflection: Type CG

Variable deflection: Type CGV

On a bended axle there are spread several bearings with rubber coated sleeves. The curved shape of the rollers generates a stretching effect and thus a spreader effect on the film. This principle can already be applied at a low angle of contact of 20°.
The position of the deflection can be altered by slew transmission and therefore adapted to the respective production.

For the variant CGV also the deflection height can be adjusted.

Area of application:

  • Avoids the formation of wrinkles in web guiding of plastic film, artificial leather, textiles, paper and similar, also during high production speed
  • Has a wide material application range, also for sensitive and adhesive material
  • Can be used for multi-slit application
  • Has a wide range of working widths

Characteristics:

  • Resistant to ozone and solvents, antistatic rubber coating
  • Different coatings available (e.g. EPDM, silicone, polyurethane, etc.)
  • Maintenance-free, long durability
  • Designed for high-speed webs, various applications
  • Special corrosion-proof types for wet material
  • Optimum angle of contact between 20° and 90°
  • Standard working widths of 400 to 6000 mm (others on request)
CG

Type AG / AGV (Banana)

Design and working principle of this spreader roller match with type CG / CGV.
However, for these types the roller surface is not rubber coated, but made of chromed steel elements.

Area of application:

  • Especially made for highly-abrasive and heavy webs
  • For very high speeds

Characteristics:

  • Different steel surfaces available, such as fine grinded, chromed, etc.
  • High wear resistance, long durability
  • Precise rotation
  • Optimum angle of contact between 20° and 90°
  • Standard working widths of 400 to 6000 mm (others on request)

Type RES (with elastic cords)

The base body consists of an extruded aluminium profile with embedded cords which are progressively stretched with the angle of contact. The extension of the cords and thus the respective spreading effect can be adjusted by lateral rotary discs.

Area of application:

  • Avoids the formation of wrinkles in web guiding of plastic film, artificial leather, textiles, etc.
  • Uniform stretching effect on the whole web widths in multi-slit applications
In order to reproduce the adjustments the mechanism can be equipped with an indicator.

Characteristics:

  • Different cords available, e.g. polyurethane, silicone, rubber, etc. (depending on application
  • Single-cord suspension, easy exchanging of cords
  • Different diameters for different productions speeds available
  • Optimum angle of contact between 110° and 170°
  • Standard working widths of 800 to 5000 mm (others on request)
