Abstract: An injection-molding process for injecting a shoe soling including at least two adjacent injection-molding layers onto a shoe upper drawn over a shoe last, uses a mold cavity including a frame, the cavity being covered at the top by the upper also serving as a mold cover, with plastic material being injected into the cavity below the upper. To produce two adjacent injection-molding layers of plastic materials having different properties and reaction times in one operation, i.e. without needing an interim mold opening, before covering the cavity a film is clamped over it by a clamp mounted on the frame. When filling the cavity, the space below the film is first filled with plastic material to produce the first injection-molding layer and then, to produce the adjacent second injection-molding layer, the space above the film is filled with plastic material. Plastic materials are used that inseparably attach to the film.
