The flat spiral belt with S-hook is a woven belts consisting of left and right spirals which are twined together by means of straight cross rods. The spirals are attached under post-tension, whereby a very dense belt surface is created.
The cross rods at the end are bended in the direction of the previous cross rod. The cross rod is then bended around the previous cross rod.

  • – Longitunal pitch: 8,5 up to 25 mm
  • – Lateral pitch: equal to wire thickness
  • – Spiral wire: ø 0,8 up to 2,0 mm
  • – Cross rod wire: ø 1,6 up to 3,15 mm
  • – Materials: all obtainable types of wire in tensile strengths of 500 – 700 N/mm2
  • – Temperature range: ambient up to approximately 1150 °C
  • – Range of the width of the belt: 200 – 4000 mm
  • – Lateral chains are a possibility (take a look at Type 1000: KE)
  • – Possibility to attach cross flights

The ES belts are characterised by:

  • – Drive on the basis of friction; large enough drive roller is necessary
  • – Preferred support: herringbone motive
  • – Pass range of the belt; very closed, small products can therefore be trans located.
  • – The high density of the belt guarantees a good and even transition of heat towards the product.
  • – Serrated cross rods make sure that the spirals remain in their position
  • – The straight belt run is guaranteed by alternated left and right spirals
  • – Tools are inflexible; not every combination of longitunal/lateral pitch/ spiral wire/cross rod wire is possible.
  • – Also possible as variant with welded sides, which causes the indication to become ‘’EG’’. In this case the belt can also be constructed with heightened side guards.

The flat spiral belts with S-sides are practically familiar with a restricted amount of applications. This however doesn’t mean that the belt type can’t be used for other applications:

  • – Oven belts in bread & pastry in industry
  • – A special version of the above mentioned is with duplex chains at the sides
  • – Belts in tunnels serving high temperature treatment processes such as tempering, harden, sintering, hard soldering, etc.
