  • Patent number: 6048190
    Abstract: The frame of a laminating press includes a plurality of spaced-apart fixed threaded fasteners over which an edge of a vacuum bag having apertures aligned with such fasteners is placed. Subsequently, a backing bar having aligned apertures is placed over the vacuum bag and second threaded fasteners are secured to the first-named threaded fasteners for clamping the edge of the vacuum bag between the channel and backing bar. In a preferred embodiment, the channel is substantially C-shaped providing a serpentine pathway and attachment of the edge of the vacuum bag to the laminating press frame, thereby securely holding the edge of the vacuum bag thereto. In a preferred embodiment also, a sealing pad is positioned on the lower surface of the frame to improve the vacuum seal between the vacuum bag and the lower adjacent table on which the part to be laminated is placed.
