Abstract
Official abstract text for this publication.
Described are methods of two-dimensionally and three-dimensionally forming an article of wear using vacuum forming in an automated process. In the two-dimensional method, the article of wear comprises a generally flat shape with three-dimensional features molded into the first material layer.
First claim
Opening claim text (preview).
That which is claimed is: 1. A method of two-dimensionally forming an article of wear comprising: positioning a first side of a first material layer adjacent a one-sided mold comprising a cut-out location; positioning a second material layer that is more breathable than the first material layer adjacent a second side of the first material layer to produce a layered assembly comprising the first material layer and the second material layer; applying a vacuum relative to the layered assembly so that the first side of the first material layer is molded to the cut-out location within the one-sided mold, so that the second material as a result of being more breathable than the first material layer is not molded into the cut-out location within the one-sided mold by the vacuum to a same extent as the first material layer, and so that the second side of the first material layer is displaced away from the second material layer so as to form an air pocket between the second side of the first material layer and the second material layer; and bonding the second material layer to the first material layer in areas outside the cut-out locations of the one-sided mold so as to maintain the air pocket formed between the second side of the first material layer and the second material layer by the vacuum. 2. The method of claim 1 , wherein the method further comprises applying heat to the first material layer and the second material layer while applying the vacuum relative to the layered assembly. 3. The method of claim 1 , wherein the method further comprises pre-heating at least the first material layer prior to positioning the first side of the first material layer adjacent the one-sided mold. 4. The method of claim 1 , wherein the method further comprises cutting the article of wear out of the first material layer and the second material layer. 5. The method of claim 4 , wherein the method further comprises separating the cut article of wear from the first material layer and the second material layer. 6. The method of claim 1 , wherein the first material layer is a non-breathable film, and the second material layer is a breathable material. 7. The method of claim 6 , wherein the article of wear comprises a formed plate having air pockets sandwiched between the first material layer and the second material layer. 8. The method of claim 7 , the method further comprising coupling sides of the formed plate to an upper so that the second material layer is facing a wearer's foot to provide breathability and wicking to the wearer's foot. 9. The method of claim 7 , the method further comprising coupling sides of the formed plate to an upper so that the first material layer is facing a wearer's foot to provide a waterproof upper. 10. The method of claim 1 , wherein applying the vacuum relative to the layered assembly does not cause the second material layer to become molded to the cut-out locations within the one-sided mold. 11. The method of claim 1 , wherein the article of wear comprises a generally flat shape with three-dimensional features molded into the first material layer. 12. The method of claim 11 , wherein the three-dimensional features comprise one or more of embossing, de-bossing, and texture features.
