Claims

[Scope of utility model registration request]

An endless lower mold member, an upper mold member that sequentially faces the lower mold member at a predetermined interval to form a mold, a synthetic resin foam raw material feeder installed in front of the mold, and a flexible sheet. comprising a sheet-like material supply device and a base material feeding device, and between the raw material supply device and the mold inlet, and while the sheet-like material faces the raw material on the base material supplied onto the lower mold member. In an apparatus for producing a synthetic resin foam having a spreading device disposed above the sheet-like material so as to cross the mold member, the sheet is spread in front of the upper mold member of the apparatus and between the raw material supply machine. A heating device for heating the sheet material to about 20 to 90° C. is installed in a space containing the sheet material supply device and the spreading device, and a looper consisting of a plurality of rollers and a heating device that can be easily attached and detached to cover the space containing the looper. An apparatus for producing a synthetic resin foam, further comprising a cover provided with a supply port for a sheet-like material and a base material, and a structure in which the heat generated by the mold is supplied into the cover.
