20220015494 · 2022-01-20 ·

A method of reclaiming used tennis balls and transforming the material reclaimed from the tennis balls into soles for footwear. This multi-step process requires acquiring used tennis balls, grinding the tennis balls into ground rubber bits (usable elements) and tennis ball “fuzz” (unusable elements). The rubber and fuzz are passed through a screen which allows the rubber bits to exit the screen but retains the fuzz. The rubber is then mixed with an H.sub.2O and Polyurethane mixture to form a rubber mixture. This mixture is then pressed into a shape using a mold, cured, and then used to manufacture footwear.

Methods for forming footwear using recycled plastics
11135796 · 2021-10-05 · ·

Presented are manufacturing systems, methods, and devices for forming footwear using scrap or waste plastic materials. A method for manufacturing an article of footwear, such as an athletic shoe, begins with receiving a batch of recycled plastic, which may include thermoplastic elastomers or ethylene-vinyl acetate, and grinding the batch of recycled plastic material. The ground recycled material is processed, for example, by adding a foaming agent that activates at elevated temperatures. The processed recycled material is placed into the internal cavity of a final mold that is shaped like a segment of the footwear, such as a unitary sole structure. To form the footwear segment, the processed recycled material is heated past the threshold activation temperature of the foaming agent such that the foaming agent causes the recycled material to expand and fill the internal cavity of the final mold. The formed footwear segment is then extracted from the mold.

ARTICLE OF FOOTWEAR AND METHOD OF MANUFACTURE

An article of footwear and a method of manufacturing the same are provided. The article comprises an upper fixedly attached to a sole structure. The upper may comprise a wall including an inner layer and an outer layer coupled to the inner layer, such that the inner layer and the outer layer define a closed pocket therebetween. A layer of scrap particulate matter is disposed in the closed pocket. The method comprises dividing scrap material into a plurality of discrete pieces of scrap particulate matter via a grinding or shredding process, inserting a layer of the discrete pieces of scrap particulate matter into the closed pocket formed between the inner layer and the outer layer of the wall of the upper. The outer layer may be formed of a sufficiently transparent material, such that the layer of scrap particulate matter is at least partially visible therethrough.
