ABSTRACT:
A press comprising a flexible pocket or elastic membrane, that is adjustable in height and serves as a means for exerting a uniform enveloping pneumatic or hydraulic pressure, between the glued insole and the mounted upper of an article of footwear, which is held between locking elements during the exertion of pressure by the pocket. The locking elements consist of a single shaper closely contacting the contours of the footwear and remaining fixed on the press frame, during operation of said pocket, and a toe support that is placed against the base of the upper at the level of the instep. Thus, any creasing of the upper portion of the footwear is avoided by securely holding the footwear immobile during the pressure operation.
