Planographic printing plate feeding apparatus |
摘要 |
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 F1 applied from the uppermost planographic printing plate to the slip-sheet is increased by such a degree that the conveyance force F1 exceeds a maximum static friction force F2' between the slip-sheet and the planographic printing plate under the slip-sheet, the uppermost planographic printing plate and the slip-sheet 22 can 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. <IMAGE>
