ABSTRACT:
In fabricating a press bending mold having a flexible metal shaping member such as a plate or a frame, a reinforcing grate and adjustable attachment means extending through certain apertures in the reinforcing grate to adjust the shape of the metal shaping member, localized distortion of the shaping member that formerly occurred when the attachment means were bonded to the shaping member by welding or soldering is eliminated by using a thermosetting adhesive capable of application at room temperature, such as an epoxy resin adhesive, to bond the attachment means to the flexible metal shaping member. When the former and the latter have bonding surfaces composed of aluminum, an epoxy resin containing finely divided aluminum filling is preferred.
