The automatic printed-wiring board production system according to this invention comprises a material feeder whereby the stacked-up copper-clad bases are stored and automatically delivered onto the transfer line one by one, a pretreatment unit for performing washing, buffing and drying of the bases, first to sixth straighteners, first to fourth automatic printers, a dryer for forced-drying the printed pattern on the copper foil, an etcher for etching away the extra printed foil at other parts than the printed pattern on the copper foil, a washing means for washing away ink on the printed circuitry, first to fourth pushers, first to fourth loading stockers, first and second buffing/drying means, first and second cooling means, first and second automatic reversers, and a final finisher which gives a fluxing treatment. All of these elements are arranged in predetermined sequence along the transfer line.
