Twin-V-Belts for robust conveying
Twin-V-Belts made of polyurethane (PU) are an optimal solution for robust conveying or for spreading applications of product strands in the food industry.
Our portfolio includes different design variants, Shore hardness gradations and reinforced profiles.
What are the characteristics of BEHAbelt Twin-V-Belts?
BEHAbelt offers different versions of Twin-V-Belts. Depending on the area of use and application, the profiles can be reinforced with so-called reinforcements (polyester, aramid, steel and weldable glass fibre PU). Thanks to different Shore hardness grades, optimum transmission and conveyor properties as well as a long service life are guaranteed.
What raw material are the Twin-V-belts made of?
BEHAbelt uses high-quality PU (polyurethane) materials for the production of Twin-V-belts, which guarantee optimum performance and a long service life in transmission and conveyor technology applications.
What are the special features of the Twin-V-belts?
The geometry of the Twin-V-Belts is wide instead of high. On the one hand, this achieves mechanical strength and, at the same time, makes it possible to use smaller pulleys.
The wide contact surface can also be coated depending on the application.
How do I splice Twin-V-Belts correctly?
Twin-V-Belts from BEHAbelt can be purchased by the metre, assembled end-to-end, delivered or welded on site.
There are two ways of welding the profiles, either butt welding (for non-reinforced profiles) or overlap welding (for profiles with tension members).
Simplified the welding process mainly takes place in four steps:
Cutting Twin-V-Belts to size
Here the belt ends are cut by means of mitre cut or straight cut (e.g. with BEHAbelt AS02).
Fixing the belt profile in the guide clamp
The guide clamp (e.g. FZ02/3) is used to align the two belt ends exactly.
Welding the belt ends
For PU belts the welding temperature should be 290°C; for TPE belts 240°C. The welding paddle (e.g. EErgo) is held between the belt ends. Then the belt ends are pressed against the sides of the paddle by lateral pressure. The material melts. After the melting phase, the welding paddle is removed and the belt ends are pressed together with the guide clamp. After the cooling period, the belt is endlessly welded.
Cleaning the Twin-V-Belt
After the welding process and the cooling time, only the weld bead has to be removed using a side cutter (BEHAbelt SE02) or a sharp knife.
Further belt profiles from BEHAbelt
Depending on the material to be conveyed, different belt profiles are required. BEHAbelt is specialised in the production of extruded thermoplastic belt profiles. Thanks to our own toolmaking and modern, flexible production facilities, we can also produce customised profiles quickly and cost-effectively.
