  • Patent number: 6595345
    Abstract: A stream of newspapers (2) is stored temporarily by dividing the stream (2) into longitudinal sections. A carrier (5, 6) is releasably connected to one long edge of each generally flat section (3), to form product units (7) which are hung side-by-side in a transport cassette (30), by resting the end-parts of the carrier on respective bearing surfaces in the cassette (30). The cassette is carried by lowerable legs which enable the newspaper sections to hang freely down from the cassette. The cassette includes transport handling means (32). A newspaper stream (2) is formed from the temporarily stored units (7), by removing the carriers (5, 6) from said sections (3) and joining said sections end-to-end.

  • Patent number: 5121825
    Abstract: A method of achieving temporary storage of a succession of objects such as newspapers, arranged in overlapping formation, comprising dividing the succession of objects into sections (1) carried along on a conveyor (22) to a position close to a series of vertically displaceable shelves (21), depositing the sections (1) on the shelves and displacing the series of shelves transversely to the direction of movement of the conveyor in order to bring the shelves into a position close to the conveyor to allow the sections to be deposited on the shelves or to be transferred from the shelves to the conveyor when the temporarily stored sections are to be fed out. An apparatus for performing the method comprises dividing the succession of objects into sections, a conveyor (22) for transporting the sections (1) through a temporary store consisting of a series of shelves (21), and transferring the sections between shelves and conveyor.
