Abstract
Abstract A method for producing an injection molded article comprises positioning pre-formed sections made of cloth or the like in the cavity of an injection mold, injecting the molten resinous material into the remainder of the cavity and cooling the material to a condition under which the latter is cured and integrally connected to the pre-positioned sections. The article produced by the above method comprises at least sections and connecting - members adapted to connect said sections to each other.
