  • Patent number: 6540864
    Abstract: In a method for making a shoe, an insole blank having a peripheral portion is prepared. An outsole which has an adhesive applied to the top thereof is positioned in a mold assembly including at least two opposite side mold parts that have forming patterns for forming the peripheral portion of the insole blank. The insole blank is placed in the mold assembly adjacent to the top of the outsole while the insole blank is being softened by heat to a plastic state. The insole blank is pressed against and is bonded to the outsole, and the peripheral portion of the insole blank is pressed and patterned via the side mold parts. The bonding of the insole blank and the outsole and the patterning of the peripheral portion of the insole blank are carried out simultaneously by closing the mold assembly.

  • Patent number: 5843352
    Abstract: The present invention relates to a production method for ornamental strips, wherein castings of dimensions smaller than or equal to the final product are pressed under heat and molded. An increased range of variations is achieved by fusing together the casting of the ornamental strip and plastic platelets of various forms, colors or material hardness, which are put on the castings. By flexibly adapting the production method to specific needs, production time and cost are saved.
