The role of paper machine roll rubber covering In paper machines, rubber-covered rollers play a vital role. Rubber-covered rollers are usually composed of a metal roller core and a high-quality rubber layer, and are an integral part of the papermaking process. It is able to transfer and flatten materials such as paper and cardboard, ensuring consistent and precise movement of paper materials, which is essential for achieving high-quality papermaking. Its grip on the paper prevents slippage and misalignment, which can lead to production errors. The cushioning effect of the rubber roller surface also helps to reduce vibration and shock, ensuring a smooth production process. In addition, the material and surface treatment of the rubber roller surface can be customized according to specific needs. This adaptability makes it easier to handle a variety of materials without causing damage or affecting production quality. The elasticity of rubber also helps to extend the life of the roller and ensure reliable performance even in continuous operation. Production process of rubber-covered rollers for paper machines 1. Roller core production: Select a roller of appropriate size as the roller core according to the size of the rubber-covered roller. After the roller core is processed to the specified size, it is also required to be sandblasted. This process can ensure that the rubber layer adheres better to the surface of the roller core. 2. Rubber refining: Select suitable rubber as the rubber layer of the rubber roller. Different rubber materials correspond to different production requirements. Usually, the rubber of the outer layer of the rubber roller is EPDM, polyurethane, silicone rubber, etc. After adding auxiliary agents, vulcanizers and other materials to the selected rubber, put it into the calender for rubber refining. 3. Rubber coating: Rubber coating is also called rubber layer winding, which usually has two methods: cold rubber coating and hot rubber coating. Hot rubber coating adopts hot vulcanization rubber coating process. This rubber coating method is suitable for rubber rollers with high precision requirements; cold rubber coating adopts the method of winding the rubber layer after applying glue. 4. Rubber roller vulcanization: The roller after rubber coating needs to be vulcanized. Vulcanization can remove toxic substances in rubber and make the rubber less likely to crack. 5. Rubber roller grinding: This is the last step in the rubber roller production process, so that the rubber roller reaches the required size and surface roughness. _______________________________________________________________ Join us on our channel to see how paper machines are produced, and how a paper mill runs the machines to get paper!
