Abstract:
For use in mounting a printing plate or the like, onto a magnetic cylinder, in combination:a) an arcuate magnetically permeable printing plate;b) a magnetic cylinder having a magnetic force at its outer surface for magnetically attracting and latching onto said printing plate when said printing plate is in close proximity to said cylinder;c) a main air passageway within the magnetic cylinder, said main passageway having an inlet opening;d) a source of pressurized air coupled to said inlet opening; ande) air passageways connected to said main air passageway extending radially to the outer surface of the cylinder for directing the pressurized air from said main passageway against said printing plate with a force in opposition to the magnetic attracting force of the cylinder on the printing plate when said printing plate is in close proximity to said cylinder.
