Usually the entire billet needs to be machined to remove any surface defects. The extruder consists of a screw, barrel or cylinder, head and die. Finished tyres need to be handled with care, so transfer roller belts are used for conveying. Tire Tread and Sidewall Extrusion. Calendered textiles are used for casing, cap plies and chafers. The method was applied to pet food production in 1950s. 0000011208 00000 n "SeN:o1p04KC)`,@XOdD[V i` 0/ P:y The milky fluid (latex) that flows out coagulates when acid is added to it. In particular, synthetic rubber and materials used to reduce wear, increase grip and extend the life of a tyre. 0000026383 00000 n A tire is a complex combination of components made from numerous ingredients. wY&UYD00p`ppDl_I A familiar example of a functional food is oatmeal because it contains soluble fiber that can help lower the cholesterol levels. [1], Metals that are commonly extruded include:[17], Magnesium and aluminium alloys usually have a 0.75m (30in) RMS or better surface finish. %PDF-1.4 % The process is used together with both traditional and industrial methods used for the production of tortillas and tortilla chips (but not corn chips), tamales, hominy, and many other items [31]. A screw-type extruder shapes the rubber into an endless strip of tread. Since the material is displaced by pressure, the outside surface is work-hardened and quite smooth. The group consisting of Bizhanov, Kurunov, etal. A multitude of textile threads are fed into the calendar by a large roller device and embedded in a thin layer of rubber. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. Lets follow a Continental tire through all five essential stages of tire manufacturing: Various branches of industry supply the tire manufacturing industry with raw materials, which are used to create the necessary compounds. Our experts can help you find the right belt. A "caterpillar haul-off" (called a "puller" in the US) is used to provide tension on the extrusion line which is essential for overall quality of the extrudate. endstream endobj startxref By Tasneem Pervez, Sayyad Z. Qamar, Omar S.A. Al-Abri IntechOpen Limited After extrusion, the weight per meter is checked and the tread cooled by immersion. How? 0000012892 00000 n [5] Friction extrusion differs from conventional extrusion in that the charge (billet or other precursor) rotates relative to the extrusion die. Forming metallic composite materials by urging base materials together under shear US patent #5262123 A, Inventors: W. Thomas, E. Nicholas, and S. Jones, Original Assignee: The Welding Institute. The resulting particle can be blended with compression aids and compressed into tablets or filled into unit dose capsules.[22]. The molten materials are passed through a spinneret that helps in forming fibers.[23][24]. A screw-type extruder shapes the rubber into an endless strip of tread. Tire Tread and Sidewall Extrusion Operations Extrusion is one of the most important operations in the tire manufacturing process because it processes most of the rubber compounds produced from the mixing operation and then prepares various components for the ultimate tire building operation.
