Sole and Method of Manufacturing the Same

Abstract

A method of manufacturing a sole, includes the following processes: (1) Daubing glue on cloth and then gluing a film onto the cloth; (2) After leaving the cloth still for a period of time, cutting the cloth glued with the film to desired shapes and then putting the cloth into a mold of the sole, the surface which is glued with the film being upward and the other surface contacting a lower mold; (3) Perfusing the liquid raw material which is used to manufacture the sole into the mold for molding, the bottom surface of the sole close connecting to the film so that the cloth connects to the sole after molding. A sole made by the above mentioned method comprises a sole body, and a cloth defined on the bottom surface of the sole body, wherein a film is defined between the cloth and the bottom surface of the sole body, the cloth and the film are connected by hot pressing after a daubing process, the film and the sole main-part are connected by a perfusion and molding process.

Description

CROSS REFERENCE TO RELATED PATENT APPLICATION [0001] This patent application claims the priority benefit of a Chinese patent application No. 200520057639.X filed on Apr. 27, 2005. FIELD OF THE INVENTION [0002] The present invention relates to the art of soles and methods of manufacturing the same, and especially to a sole glued with cloth and a method of manufacturing the same. BACKGROUND OF THE INVENTION [0003] Soles of shoes that people usually wear are commonly made of synthetic rubber material. Such soles are always so stiff that the impact between soles and the floorboard while walking at home may easily break the expensive floorboard. And the friction between the soles and the ground while walking on the street may also easily abrase the soles. The prior method to solve above problems is to glue cloth onto a front portion and a heelpiece of the sole so that the soft cloth which contacts the floorboard and the ground could not only avoid breaking the floorboard of a city family...

AI Technical Summary

Benefits of technology

The present invention provides a novel sole glued with cloth to achieve a fast connection of the cloth and the sole, and to ensure that the cloth is glued onto a correct place and the cloth has a neat facies. The method of manufacturing the sole prevents the raw material from easily infiltrating into the cloth during the perfusion and molding process. The film made of polyamine ester is added between the cloth and the sole main-part to connect them fast and securely. The method is efficient, cost-effective, and the film prevents the liquid raw material from infiltrating the cloth, keeping it clean and neat. The invention solves the problem of slow and inaccurate connection between the cloth and the sole in the prior art.

Problems solved by technology

Such soles are always so stiff that the impact between soles and the floorboard while walking at home may easily break the expensive floorboard.

And the friction between the soles and the ground while walking on the street may also easily abrase the soles.

Because the above working procedure are mostly operated by people, it has the following disadvantages: (1) The petroleum used as the solvent is easy to volatilize into the air during treatment and roasting process and it may injure people when inbreathed by people; (2) The inconvenient and repeating operations are waste of manpower, material resources and electric power; (3) It is difficult to glue the cloth onto the correct place so that it may easily result in brokenness or disuse of the cloth when it is glued onto a incorrect place and torn to glue again, so as to increase the production cost; (4) The daubing and gluing processes need 4 workers to complete.

It is easy to pollute the sole and workers often need to do poorly done work over again.
