Abstract
Abstract The essence of the invention resides in the cooperative operation of synchronized components from which results the automatic production of one or two pocket record jackets. The invention comprises an elongated carriage having a laterally extending carriage portion forming a ''''T'''' shaped machine. At one end of the elongated carriage there is provided a feed mechanism which feeds a first paperboard blank to a notching station where a part of the longitudinal edges are notched. From the notching station the paperboard notched blank is fed to a scoring station where the notched blank is appropriately scored so that glue flaps may be formed at the feed station. Simultaneously, from the opposite end of the elongated carriage there is fed a second paperboard blank, from a feed station and the two blanks are joined together at a rotary station where the second blank is glued atop the first blank and where one or two phonograph record pockets are formed. The joined blanks are urged in a transverse direction onto the laterally extending carriage portion of the T shaped machine by a conveyor transfer mechanism. The joined first and second paperboard blanks thereafter travel to a die mechanism where they are scored and trimmed to form a spine and are moved to a second folding station where through a conveyor and bar device one half of the joined paperboard blanks is folded 180* along the score lines onto the other fold, thereby forming the completed record jacket having one or two phonograph record pockets.
