ABSTRACT:
An apparatus for making a foot-shaped layer, such as an insole member of a shoe. The apparatus includes a top plate having an opening of a predetermined area and mutually adjacent bar-like measuring elements supported in an individually vertically movable manner under frictional resistance within the opening. A heating chamber is provided adjacent to the top plate for heating a sheet of thermoplastic therein to a plasticized state. In accordance with the method, a plasticized sheet of the film is placed on the opening so as to cover the upper end surfaces of the measuring elements so that upon stepping on the sheet with a foot, the film is molded to the shape of the foot. The molded film is then cooled and cut along the outline of the foot to obtain a layer which may be used to define the shape of an insole member.
