Essential for Success – Winding Belts by AFH-Antriebstechnik

Winding belts are the central link between a machine and the end-product.
Winding belts are primarily used in the production of paper and paper tubes. During the spiral winding of round tubes several glued paper webs are wound onto a fixed mandrel, the amount depending on the intended use and the associated strength requirements.

Practical experience shows time and again that smooth production processes can only be achieved if both the dimensions and the surface quality of a winding belt are individually tailored to suit the requirements in question. Most of the known problem situations can be avoided in advance solely by the selection of the correct belt.

For a long time we have been developing and testing out our winding belts in close collaboration with our customers. We thus grow with their requirements and consistently maintain our products at the latest state of the art.

Score of application:

Winding of paper and cardboard tube

Fabric:

Customised selection of the type of fabric and quality. All fabrics are produced endless and connectionless with woven edges using a special production process.

Type of fabric: Polyester

Tear resistance:   2-3 mm belt thickness  = 125 kg / cm belt width
Tear resistance:   4-5 mm belt thickness  = 250 kg / cm belt width
Tear resistance:   8 <  mm belt thickness  = 375 kg / cm belt width

Type of fabric: Aramid (Kevlar©)

Tear resistance:   Aramid  = 500 kg / cm belt width

The fabric quality can be individually adjusted for higher demands.

Features:

  • Endless and connectionless
  • Woven edges (no fraying)
  • Customised manufacture
  • No breaking points
  • Homogeneous running behaviour
  • Very high flexibility
  • Suitable for small roller diameter
  • No thickening or adhesive points
  • High heat resistance
  • Non-directional

Coating:

Application-based selection of the coating material. An innovative coating process, without the use of additional binding agent, guarantees a homogeneous and connectionless coating.

Coating: PVC

  • Hardness grade 35-90 Shore-A available
  • Customised additional constructions
  • Infinite combination options of various Shore hardness values
  • High abrasion resistance
  • Excellent grip properties
  • Suitable for small roller diameter
  • Temperature resistance -10°C / + 80°C
  • Homogenous coating throughout
  • No thickening or adhesive points → No breaking points
  • Non-directional
  • High flexibility
  • Resistant against most adhesives, oils and greases

Calculation of a basic belt:

Calculation of the belt length: (2xe)+d+f

Calculation of the belt width: the belt should be 5-7 mm narrower than the final paper web
(Example.: final paper web 125 mm → belt width 120 mm)

e  =  average distance between axles
d  =  circumference of the drum
f  =  circumference of the tube
