METHOD OF VACUUM FORMING A FOOTWEAR UPPER

A method of making an article of footwear (100) is provided. The methodcomprisespositioning a sheet (1540, 1640, 840) of upper material (1540, 1640, 840) within a chamber (1605) , the sheet (1540, 1640, 840) dividing the chamber (1605) into a first compartment (1660, 1665) on a first side of the she...

Zusammenfassung:	A method of making an article of footwear (100) is provided. The methodcomprisespositioning a sheet (1540, 1640, 840) of upper material (1540, 1640, 840) within a chamber (1605) , the sheet (1540, 1640, 840) dividing the chamber (1605) into a first compartment (1660, 1665) on a first side of the sheet (1540, 1640, 840) and a second compartment (1660, 1665) on a second side of the sheet (1540, 1640, 840) . The method furthercomprisespositioning at least a portion of a footwear (100) last in the first compartment (1660, 1665) on the first side of the sheet (1540, 1640, 840) of upper material (1540, 1640, 840) . The method furthercomprisesapplying an environmental pressure differential across the sheet (1540, 1640, 840) of upper material (1540, 1640, 840) ,whereina first environmental pressure in the first compartment (1660, 1665) is lower than a second environmental pressure in the second compartment (1660, 1665) . Accordingly, the environmental pressure differential draws the sheet (1540, 1640, 840) of upper material (1540, 1640, 840) against the footwear (100) last thereby forming at least a portion of an upper (105, 605, 705) of the article of footwear (100) . The method furthercomprisesassembling the article of footwear (100) including fixedly attaching the upper (105, 605, 705) of the article of footwear (100) to a sole structure (110) .
