Title:
METHOD FOR SEALING SHOES AT SOLE PART
Document Type and Number:
Japanese Patent JPS6420803
Kind Code:
A
Abstract:
PURPOSE: To attain excellently water resistant joining by performing injection molding by applying an injection molding metal mold, which stands erect toward an insole part and has a seal lip extending to both sides of a joining part to be sealed, to the instep sole side joined to an insole part. CONSTITUTION: A layer 5 of a liquefiable material being water resistant in a cured condition is used, and injection molding of the layer 5 is performed on a joining part 3 by an injection molding metal mold 30, and the joining part 3 between an instep 1 and an insole 4 of a water resistant shoe is sealed so that water does not pass through it. In this case, the injection molding metal mold 30 which stands erect toward an insole 4 part and has a seal lip assembly 31 extending to both sides of the joining part 3 to be sealed, is applied to the sole side of the instep 1 joined to the insole 4 part, and injection molding of the layer 5 is performed in a part regulated by the seal lip assembly 31. As a result, joining between the instep 1 and the insole 4 part of the shoe which holds water resistance over a long period of time, can be achieved.
