Abstract
A method for making a shoe outsole comprises placing rubber against a coating of cured rubber cement on a segment of fabric, heating the rubber to a temperature below the melting points of the cured rubber cement and the rubber, but high enough to render the cured rubber cement and the rubber tackily adherent to each other and vulcanizing the rubber, thereby to adhere the segment of fabric to the rubber, and cooling the vulcanized rubber to form an outsole having an exposed ground-contacting surface that includes the segment of fabric.
Claims20
A method for making a shoe, comprising:
- (a) forming a shoe outsole, comprising acquiring a segment of fabric bearing a coating of cured rubber cement, placing rubber against the coating of cured rubber cement, heating the rubber to a temperature below the melting points of the cured rubber cement and the thermoplastic rubber, but high enough to render the cured rubber cement and the thermoplastic rubber tackily adherent to each other and vulcanizing the rubber, thereby to adhere the segment of fabric to the rubber, and cooling the vulcanized rubber to form an outsole having an exposed ground-contacting surface that includes the segment of fabric, and
- (b) attaching a shoe upper the outsole.
A method of making a shoe comprising:
- coating a side of a sheet of fabric with rubber cement;
- allowing the rubber cement to cure and form a coated fabric sheet;
- positioning the coated fabric sheet inside a mold with the rubber cement coated side up;
- inserting rubber into the mold on top of the coated fabric sheet inside the mold;
- vulcanizing the rubber and the coated fabric sheet inside the mold and forming a resultant outsole;
- cooling in the outsole and removing the outsole from the mold;
- and,
- attaching a shoe upper to the outsole.
A method of making a shoe comprising:
- providing a sheet of fabric;
- applying a rubber cement to one side of the sheet of fabric that is opposite a fabric side of the sheet fabric;
- allowing the rubber cement applied to the one side of the sheet of fabric to seep into the one side of the sheet of fabric and leave a coating of the rubber cement on the one side of the sheet of fabric that is opposite the fabric side of the sheet of fabric;
- allowing the coating of the rubber cement on the one side of the sheet of fabric to cure and form a coated fabric sheet with a cured rubber cement coating on the one side of the coated fabric sheet;
- positioning the coated fabric sheet in a mold with the cured rubber cement coating on the one side of the coated fabric sheet exposed in the mold and the opposite fabric side of the coated fabric sheet lying against a bottom surface of the mold;
- inserting rubber into the mold on top of the cured rubber cement coating on one side of the coated fabric sheet;
- vulcanizing the rubber and the coated fabric sheet inside the mold and forming a shoe outsole;
- cooling the shoe outsole and removing the shoe outsole from the mold with the outsole comprising an exposed ground-contacting surface of fabric and vulcanized rubber;
- and,
- attaching a shoe upper to the outsole.
