    摘要： The present invention relates to a pouch molding apparatus, and more particularly, to a pouch molding apparatus, in which a second stripper uniformly and strongly presses a pouch film around a cup part molding position of the pouch film to minimize an occurrence of wrinkles around the cup part, prevent cracks or fractures, which may occur due to the wrinkles, and improve molding quality, thereby achieving space efficiency of the cup part and maximizing energy density.
    The pouch molding apparatus according to the present invention include: a die plate which has a flat plate shape so that a pouch film is seated on an upper portion thereof and in which a cup part molding hole having a shape passing through top and bottom surfaces thereof is formed; a first stripper which is configured to press and fix the pouch film from an upper side of the die plate and in which a punch hole having a shape passing through top and bottom surfaces thereof is formed at a position corresponding to the cup part molding hole; a punch part drawn in and out of the punch hole of the first stripper and the cup part molding hole of the die plate to mold the pouch film; and a second stripper provided to protrude from a bottom surface of the first stripper and provided along a circumference of the punch hole to press and fix the pouch film.

    摘要： A conformable apparatus (100) for treating a composite material (110). The conformable apparatus (100) includes a contact layer (20) that is conformable and includes a plurality of contact elements (10). Each contact element (10) of the plurality of contact elements (10) includes a first major side (11), a second major side (12) opposed from said first major side (11), and at least one side surface (13) extending between said first major side (11) and said second major side (12). The contact layer (20) further includes a contact surface (21) at least partially defined by the first major sides (11) of the plurality of contact elements (10) and a backing surface (22) at least partially defined by the second major sides (12) of said plurality of contact elements (10). The conformable apparatus (100) also includes a backing layer (30) positioned against said backing surface (22) of said contact layer (20).
