ABSTRACT:
A driving belt has a textile supporting element composed of multi-functional threads or yarns which contain plastic fibers of high breaking strength and heat-resistant natural fibers. The driving belt also contains an electrically conductive element. The supporting element is connected to a non-crosslinked plastic covering to form an asymmetric structure. The textile supporting element can be impregnated on the side facing away from the plastic covering. The electrically conductive element is either an electrically conductive filament in the multifunctional thread or yarn or an electrically conductive layer between the supporting element and the plastic covering. This asymmetric structure results in a favorable kinematic operating behavior and high efficiency, because the neutral bending plane of the belt comes to rest at a point very near the contact surface of an element to be driven. Together with the anti-static properties and the positive connection between the supporting element and the plastic covering, the driving belt prevents the adhesion of fiber fly and makes it possible to cut it off from a supply roll as desired and connect the belt ends without any impact effect during passage over a spindle.
