METHOD FOR GATHERING FOOT FORM REQUIRED FOR MANUFACTURING CUSTOM-MADE SHOE, AND METHOD OF MANUFACTURING LAST REQUIRED FOR MANUFACTURING CUSTOM- MADE SHOE OR READY-MADE SHOE FROM BIODEGRADABLE PLASTIC OF MELTING POINT 60C OR LESS, AND MANUFACTURING METHOD OF SHOE AND THE LIKE BY BIODEGRADABLE PLASTIC LAST IN WHICH USE OF PRODUCT OF CHEMICAL SUBSTANCE ORGANIC SOLVENT IS RESTRAINED TO THE UTMOST BY TAKING ENVIRONMENT AND HUMAN BODY SOURCE INTO CONSIDERATION

摘要

PROBLEM TO BE SOLVED: To provide a technique for precisely transferring a foot form (male mold) required for manufacturing custom-made shoes and ready-made shoes from a foot form (female mold), making the use of the foot form (male mold) and inexpensively and accurately molding a rigid last for manufacturing shoes in a short time. ;SOLUTION: Cost of a modeling agent is reduced, strength of a foot form (female mold) is increased and resin thinning is prevented by mixing calcium carbonate into aqueous silicone by maximum 75%. By injecting a biodegradable plastic melting at 60C into the foot form (female mold), rigid and solid foot form (female shape last) is extremely easily manufactured. By adding three-dimensional information on foots and walking collected from 3D video and a pressure sensor device to the foot form and mechanically adding corrections, manufacturing processes for shoes for avoiding various kinds of troubles about foots and walking are introduced.;COPYRIGHT: (C)2001,JPO
