Abstract
PURPOSE: To facilitate production of a large product by a method wherein a parting member is inserted between plural belt-formed materials which will constitute inflated portions, leaving a connection portion, and the assembly is press formed for producing a series of interconnected long hollow body having tubular inflated portions.
CONSTITUTION: Reinforcing rubberized duck 3 is arranged to envelop a parting sheet 4, blank rubber sheets 1 and 2 are placed on and under the duck 3, and correction raw rubber pieces 5 are arranged for filling up end gaps, to form a belt- formed material 6 which will constitute a tubular inflated portion 6' after vulcanized. In a similar manner, there is prepared a belt-formed material 11 which will constitute another tubular inflated portion 11' after vulcanized. A parting sheet 13 is inserted between the materials 6 and 11, leaving a connection portion 17' which afterwards will constitute a connection portion 17. The assembly is inserted in a press, vulcanized and formed. Thus, a large product usable in a rubber dam, wave-absorber, or the like can be produced easily.
