Abstract

PURPOSE: To conduct foamed forming of the foamed synthetic resin by using a film as a release agent, without using any special release agent, by a method wherein a forming material of foamed synthetic resin is carried, being wrapped by a baglike part of the film, into a double conveyor for forming and foamed and hardened therein.
CONSTITUTION: While a forming material 3 being fed on to a film 1 positioned on a lowerside-type conveyor 5a and both lateral ends of the part of the film 1 whereon the forming material 3 is fed being lifted, the lateral ends are welded to each other by a supersonic heating-welding machine 8 and thereby a baglike part 4 is formed successively. The forming material 3 thus wrapped in the baglike part 4 is carried into a forming mold 7 constituted by upper and lower conveyors 5b and 5a, being foamed and hardened successively by heating. Since the foamed synthetic resin is wholly covered with the film 1, a formed article can be released from the forming mold 7 without any special release agent layer provided in the forming mold 7.
