IPC: H04R7/20
Filed: 1982-04-07
Abstract: PURPOSE:To obtain an edge material having a uniform direction of air bubbles, by setting a double-cylindrical mold, injecting stock solution of a foaming agent between the inner and outer cylinder parts of the mold to foam the stock solution and to obtain a resin foamed body and to cut the resin foamed body into a circular shape with a prescribed thickness. CONSTITUTION:A double cylindrical mold 10 contains an inner cylinder part 10b and an outer cylinder part 10a and is set perpendicularly. An urethane stock solution 11 of foaming agent is injected with a hose 12 between the cylinders 10a and 10b. The solution 11 expands perpendicularly between both cylinders. Thus a resin foamed body 14 is obtained. The numerous air bubbles 15 produced in the foaming process form a vertically oblong shape owing to the effect of gravity, etc. Such a molded cylindrical foamed body 14 is taken out of the mold 10 and then cut successively in a direction crossing the direction of the axial line and with a prescribed thickness. Thus a circular edge material 14a is obtained. The foam of each bubble 15 is approximately circular, and these bubbles are distributed with even density over the entire circumference of the material 14a and with no directivity.
