Type 330, 340


The belt is produced alike the type 300 from wide woven spiral wire. It is produced with more cross rods per one pitch (3 or 4) to get the maximum density of the belt. Welding finishes the ends of these cross rods. The spiral wire has a flat profile in this case. This belt is very dense and retains heat well.


  • straight run of the belt
  • the smooth surface of the belt makes possible the transport of products with small contact area
  • small open area allows the transport of little products
  • high belt density allowing good heat accumulation and preservation
  • long lifetime of the belts


As cooling and staging belts in glass factories, a conveyor belt for hardening and tempering furnaces, a conveyor belt in the food-processing industry, a conveyor belt in electro-technical and engineering industry, etc..
