    Abstract: A feeding apparatus for a wide metal strip, wherein a plurality of through-holes are formed with predetermined gaps in a length direction and a width direction, into a cutter and pulls narrow metal strips formed by cutting the wide metal strip between the through-holes in the length direction so that through-holes are formed along only the length direction. The feeding apparatus includes a feeding-in apparatus that is provided on an entrance side of the cutter that feeds the wide metal strip into the cutter and a pulling-out apparatus that is provided on an exit side of the cutter that pulls out the narrow metal strips, which have been cut out by the cutter.
