Abstract
In a planographic printing plate feeding apparatus, a load W applied to a stack of plates by a pickup roller which feeds a planographic printing plate from the stack is adjusted. If the load W is increased and exceeds a single feeding threshold, and if a conveyance force Fapplied from the uppermost planographic printing plate to the slip-sheet is increased by such a degree that the conveyance force Fexceeds a maximum static friction force F' between the slip-sheet and the planographic printing plate under the slip-sheet, the uppermost planographic printing plate and the slip-sheetcan be conveyed integrally (set feeding). Hence, it is possible to obtain a planographic printing plate feeding apparatus with a compact, simple and inexpensive structure and able to feed a planographic printing plate swiftly and reliably.
