Endless belt PORUFLEX

roundtextilePU

Our endless turned round belts are wound either out of one homogeneous strand or one cord and spliced endlessly without thickening. For special applications, it is possible to vulcanize the inner splice or to make a special splice based on our in-house engineering methods. This increases the tensile strength by up to 60%. In elastic types, the core is welded. In view of their special structure, twisted round belts exhibit very quiet running properties, are extremely flexible and, thus, make possible very small minimum pulley diameters of 3x belt diameter. For several types, speed up to 70,000 rpm is possible; however, the speed of 60m/s should not be exceeded. All textile belts can be impregnated with various types of coatings to protect the textile fibers against frictional wear, to increase the friction coefficient or, depending on the customer’s specifications, to realize certain properties. We use special thermal fixation processes to ensure that the operating elongation is as low as possible for belts with limited extensibility.
