optibelt ALPHA V timing belts are made from open-ended, extruded optibelt ALPHA LINEAR timing belts that are welded together to achieve the specified length. These are ideal for conveying technology.
Despite the break in the tension cords at the finger spliced joint, the welded timing belts still achieve at least 50% of the permissible tractive force achieved by belts with continuous cords. This is due to the high strength of the thermoplastic polyurethane.
When polyamide fabric is welded to the polyurethane belts, the fabric is simply butt jointed and not bonded together at its ends. In contrast, the coatings of reinforced top surfaces, T2, yellow PU foam and APL plus coatings as well as the tooth side of the belt can be welded without a joint as a composite.
