Title: Forming of tire
Inventor: SENDA SHIGERU
IPC: B29D30/62
Filed: 1984-04-10
Abstract: PURPOSE:To prevent a breaking of a rubber strip during the work and to improve a working efficiency and, at the same time, to improve the performance and quality of a finished product of a tire by continuously extruding a rubber strip from an extruder at an extremely low speed when a tire is being replaced after the previous one was formed. CONSTITUTION:Even when a tire is being replaced after the previous one was formed, a rubber strip is extruded from an extruder continuously at an extremely low speed. The above method is the most effective when a cross section of the rubber strip 6 is a trapezoid. In other words even if a tire is being replaced, the shape of a trapezoid of the rubber strip 6 may be maintained by continuously extruding the rubber strip without stopping the operation although the speed is extremely low. A working efficiency can be greatly improved by the above method, eliminating an occurrence of compressed portions.
