PTFE Seam Fusing Belts means fusing belt with joint.It is the most common fusing belts due to its lower cost.

Three joint methods are provided as below:

Overlap Belt Joint: Overlap joints are a simple and easy joint to use where having an even surface is not critical. This is the most popular seam because it is strong inexpensive and easiest to produce. The disadvantage of the overlap seam is that it is not very smooth and in some applications the seam may mark the material being fused. In addition, because the overlap seam is more than double the thickness of the rest of the belt it is slightly stiffer and suffers from early flex fatigue and very often breaks.

 

Scarfed Belt Joint: A scarf joint is similar the overlap but offer a smooth transition for the product to run offering no lip for products to catch on.This is the smoothest, strongest, most flexible seam available today. It resembles a 30 mm overlap seam but is much smoother and more flexible. There is no almost double thickness, as the mating surfaces are carefully ground to a taper and securely welded.

 

Angled Belt Joint: This seam is cut at a slight angle helping the belt to roll easily over the fusing machine rollers, reducing flex fatigue. The angle of the overlap can be varied, so that the splice does not run over the conveyor pulleys in one line. 45° and 70° are popular.
