When manufacturing various electric rubber rollers, it is necessary to coat the surface of the mandrel with a layer of rubber made of special materials. The usual practice is to press the mandrel into the finished rubber tube. In order to prevent the finished rubber roller mandrel from sliding in the rubber tube, before pressing the mandrel into the rubber tube, it is necessary to apply glue on the surface of the mandrel so that it can bond with the rubber tube.
