Connection methods for belt profiles
Regardless of whether you are using unreinforced belts or reinforced belts, we distinguish the following connection methods: butt and overlap welding.
Two connection methods can be used on profiles with reinforcement. Butt welding to reduce elongation without changing the belt strength. Overlap welding to reduce elongation and increase the belt strength.
Welding types for conveyor belts
Elastic monolithic PU conveyor belts from BEHAbelt offer new possibilities for endless joining due to the full PU belt construction. Due to the belt design without traction-layer, a connection by finger welding is no longer necessary, as the monolithic belt is a homogeneous belt design in itself – even in the joining area.
A preferably homogeneous design of the joint is a quality criterion both functionally and with regard to the elastic elongation behaviour of the monolithic strip.
In principle, this potentially “inhomogeneous“ area should be as narrow as possible, since the relatively large pretensioning force applied to monolithic tapes of 0.5…4% inhomogeneity in the belt is very quickly visible in the tensioned state.
