Tips to Avoid Belt Ripping and Creasing

Follow these tips for maximum belt life

  1. Follow all procedures detailed in your manual for the initial heat setting of the Nomex Belt. (This is accomplished at the factory for all new machines)
  2. It is important to allow the Heat Press Drum to reach operating temperature before turning the Nomex Belt.
  3. Use only the minimum amount of tension required to engage the belt. Even small amounts of superfluous tension can initiate product creasing.
  4. Initial "threading" of product materials (fabric, paper, etc) in an even manner is critical. Cut the leading edge of materials in a bullet or pointed pattern which allows for the center of the material to make the initial contact with the Drum - apply equal and outward pressure by hand to the material on the input table as it moves into the input nip (Thread the fabric first, then follow with the transfer paper.)
  5. Zero to minimum tension on the transfer paper unwind provides for better stability and less rippling feeding into the machine. (Use the idler roller at the input table forward edge for routing transfer paper.)
  6. Using a dancer type "free" roller at the input table forward edge (adjacent to the existing idler roller) stabilizes the transfer paper as it travels over the table and into the nip. This roller forces any rippling or inconsistencies to remain "upstream" of the roller. (A standard cardboard core serves well in this capacity.)

Safety Features Offered to Prolong Belt Life

Many of AIT/Astex Heat transfer machines are equipped with safety features that can prevent belt damage:

  1. If the air pressure of the machine should ever fall beyond the set threshold, the Nomex belt alignment system has an auto-shutoff mechanism to prevent belt damage
  2. Heat press machines equipped with an automatic cool down timer will allow the heat drum to cool down to the appropriate temperature to avoid Nomex belt damage.
  3. Tracking sensors realign the Nomex belt during heat press operation. If the Nomex belt over travels to one side, the tracking sensors will disengage the machine.

We also carry new nomex belts for situations when existing belts are beyond repair.
