Double Roll Roller Die Hot Gum Edging System

The Steelastic Double Roll Roller Die at work with a Hot Gum Edging Machine.

The Double Roll Roller Die (DRRD) Hot Gum Edging System is Steelastic’s latest innovation in single compound gum application for steel belts. With this machine, the rubber is extruded via a die into a double roll system to produce highly tolleranced gum material. The gum is then slit and applied to the steel belt, either top applied or wrapped.  

 

Advantages of the DRRD Hot Gum Edging System

  • Produces extremely thin gauge gum material as low as 0.25mm (max 1.5mm) 
  • Able to hold very tight tolerances on both gauge and width due to the double roll roller die and precise slitting operations. 
  • Designed to allow for stops and starts in the belt production process with application speeds from 3 to 21m m/min. 
  • Eliminates the cost to calender, slit, and handle cold gum material.  
  • Eliminates the material and removal costs associated with the poly liner in cold gum application systems, hence reducing waste and improving sustainability. 
  • Can be added to any tire component manufacturing line, not only Steelastic machines.
