1. An apparatus for manufacturing a reinforcing cloth of a seat pad, the apparatus comprising:
- a mold with an internal space for fixing a sheet, formed as a hollow shell of a single material, the mold having an outer shape that is substantially identical to a shape of the reinforcing cloth, the mold including a plurality of air holes provided through the shell, the air holes interconnecting the internal space with an outer surface of the mold;
a cover member formed of a bag-shaped film, for forming a closed space inside thereof by covering the mold, the cover member being removable from the sheet after molding the sheet into a shape;
a heating unit for heating the sheet; and
an exhausting unit for exhausting air from the closed space,wherein the heating unit supplies heated air to the closed space through the air holes of the mold by supplying the heated air to the internal space of the mold and the exhausting unit exhausts air from the closed space through the air holes of the mold,wherein the cover member is capable of deflating to be sucked by the mold so that the sheet is deformed to be sucked and comes into close contact with the mold when the air in the closed space is exhausted by the exhausting unit, andwherein a contour of an inner surface of the mold and a contour of an outer surface of the mold is substantially similar.
