Abstract
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.
Claims12
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.
