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. A linking member drives the feeding-in apparatus and the pulling-out apparatus in concert so that the wide metal strip is fed into the cutter together with the narrow metal strips out being pulled out from the cutter.

Abstract: A cutting apparatus that cuts a plate-like body in a feeding direction thereof includes: a first die disposed on one side of the plate-like body with a plurality of cutting blades, which include fixing portions, mounted thereon. A second die disposed on another side of the plate-like body with a plurality of cutting blades, which correspond to the cutting blades mounted on the first die, Fixing portions, mounted thereon by attaching the fixing portions and a driving apparatus for driving at least one of the first die and the second die toward the other die, wherein the lower mold and the upper mold have a plurality of attachment holes which, to enable the fixing portions to be inserted and mounted, are each formed with inner wall surfaces that contact the entire periphery of a fixing portion and an inner bottom surface that contacts a bottom surface of the fixing portion.
