Separator manufacturing apparatus for forming a separator plate having ribs of resinous material on a base sheet

A separator manufacturing apparatus for forming a separator plate having ribs of resinous material on a base sheet, which comprises:

• a transfer roller with a plurality of annular shaping grooves having a predetermined shape corresponding in cross section to the ribs, said ribs being formed in the outer circumferential surface of said roller and extending in its circumferential direction,
• a resin feeding device with a nozzle means having a plurality of nozzles positioned to separately feed a hot-melt type resin having highly adhesive properties to each of said annular shaping grooves of the transfer roller,
• a base paper feeding device to feed a continuous base paper at a predetermined speed to a part of said outer circumferential surface of the transfer roller at the time of feeding said resin to thereby form by transfer a plurality of said ribs having a predetermined shape corresponding to the annular shaping groove on a surface of said continuous base paper, and
• a parting agent coating device for applying before the feeding of said resin a thin layer of parting agent to at least a portion of said annular shaping grooves on said transfer roller.
