Systems and methods for utilizing phylon biscuits to produce a regionalized-firmness midsole

摘要

A method for producing a regionalized-firmness midsole utilizing a heat press, and a description of the resultant product, are provided. Initially, the method involves providing a plurality of pre-formed phylon biscuits. Typically, the plurality of biscuits includes at least a first biscuit that has a first density and a second biscuit that has a second density. The method may further include the steps of arranging the biscuits into a receiving area of the heat press, and integrating the plurality of biscuits to form the midsole by activating the heat press. Integrating the biscuits includes raising the biscuits above a threshold temperature, and causing the biscuits to expand such that each of the plurality of biscuits couples with another of the biscuits to form a midsole with two or more degrees of firmness located at distributed regions thereon.

主权项

1. A regionalized-firmness midsole comprising:
at least one fused pre-formed ethylene vinyl acetate biscuit having a first density and formed into a first shape in a first molding process, wherein the first shape corresponds to a portion of a receiving area of a heat press mold for a second molding process; a quantity of fused pelletized ethylene vinyl acetate, wherein the quantity of pelletized ethylene vinyl acetate has a second density, wherein the at least one pre-formed ethylene vinyl acetate biscuit is arranged within the quantity of pelletized ethylene vinyl acetate in a receiving area of a heat press prior to fusing the at least one pre-formed ethylene vinyl acetate and the quantity of pelletized ethylene vinyl acetate during the second molding process.
