Joint methods
There are multiple ways of endlessing conveyor belts, each offering its own advantages:
Vulcanization
A conveyor belt can be made endless by means of a vulcanization. With the help of a heat press or high frequency machine both ends can be vulcanized together. Different joint methods can be applied. The selection of the type of joint depends on the number of fabric plies, the construction and running direction and the load on the belt.
Steel fasteners
Conveyor belts can also be made endless by using belt fasteners. A belt fastener consists of a strip of eyes which are hydraulically pressed in both belt ends. Then, a connection thread can be pushed through the eyes. Especially in situations where the conveyor belt has to be changed regularly, belt fasteners are convenient.
YONGLI has an extensive range of fasteners in various types and dimensions (0,5-6 mm) from renowned suppliers, suitable for both light and heavy applications. Connection threads or tendons can be supplied in steel or in stainless steel.
Plastic fastener
Similar to steel fasteners, plastic fasteners are convenient in situations where the conveyor belt has to be changed regularly. Or when a belt has to be installed locally without the possibility to add a vulcanising press. Additionally, plastic fasteners can be especially suitable in combination with metal detectors.
Besides standard plastic fasteners, YONGLI has especially developed castellated fasteners. By fabricating the eyes of the fasteners from the ends of the conveyor belt, the fastener forms an integral part with the conveyor belt, making the fastener is less vulnerable.
