A disc record manufacturing method and apparatus wherein a record pressed at a press station is transported to a trimming station where flash is trimmed from the record with the trimmed record then being transported beyond the trimming station. While the record is maintained in a horizontal attitude during the pressing and trimming operations, when transported beyond the trimming station the record is pushed along guides which guide the record in such a way that it changes from its horizontal attitude to a substantially upright attitude in which the record is permitted to fall downwardly. An envelope is held with an open upper end thereof situated in the path of downward falling movement of the record so as to receive the latter, and then the envelope with the record therein is released to drop to a stacking guide where the envelope with the record therein remains in an upright attitude while a horizontal stack is formed from a series of envelopes with records therein. The trimmed record is guided by a pair of guide bars which are curved in such a way that when the record is pushed to the curved portion of the guide bars the record tilts from its horizontal to its upright attitude and is then free to fall downwardly along the guide bars into the open end of a waiting envelope.
In a method for manufacturing a disc record, the steps of pressing, at a press station, a record from a preliminarily formed cake while simultaneously attaching labels to opposed faces of the record and while maintaining the pressed record in a horizontal attitude, with a flash being formed along the periphery of the pressed record at said press station, then transporting the thus-pressed record from said press station to a trimming station whill still maintaining the record at a horizontal attitude, trimming the flash from the record at said trimming station while still maintaining the record at a horizontal attitude, then transporting the thus-trimmed record away from the trimming station to a predetermined location while maintaining the record in a horizontal attitude, then pushing the record along stationary downwardly curved guides to free the record for falling movement under its own weight while simultaneously guiding the record during its falling movement in a manner changing said horizontal attitude into a substantially upright attitude, so that the record while in said substantially upright attitude falls downwardly along a given path, and holding an envelope with an upper open end in the path of falling movement of the substantially upright record so that the record is received in the envelope.
In an apparatus for manufacturing disc records, pressing means at a press station for pressing a record from a preliminarily formed cake while simultaneously attaching labels to opposed faces of the pressed record and while forming a flash along the periphery of the pressed record, trimming means situated at a trimming station beyond but substantially at the same elevation as said pressing means for trimming flash from a record, holding means situated beyond but at an elevation lower than said trimming means for holding an envelope in a substantially upright attitude with an upper open end in readiness to receive a trimmed record, transporting means for simultaneously transporting a pressed record from said press station to said trimming station, a trimmed record from said trimming station to a given location beyond the latter and a third record previously situated at said location beyond the latter location, said transporting means maintaining the records in a horizontal attitude while they are transported from the press station to the trimming station and from the trimming station to said given location, and stationary guide means extending from the latter location to said holding means for guiding a record transported beyond said location in a manner changing the attitude of the record from a horizontal attitude to a substantially upright attitude while guiding the record in its substantially upright attitude for falling movement into the envelope through the upper open end thereof while the envelope is held by said holding means, said guide means forming an extension of a part of said transporting means which transports a record from said trimming station to said given location, said guide means including elongated stationary bars which are parallel to and spaced from each other and which have directed toward each other grooves for receiving opposed edge regions of a record, said transporting means including a push pin for pushing a circular record at a rear edge region thereof along said grooves and said bars being curved downwardly beyond said location to change the attitude of the record and to permit the latter to fall while in a substantially upright attitude into an envelope held by said holding means.
