Blank manufacturing apparatus and manufacturing method

Abstract

The present invention provides a blank manufacturing apparatus that can improve the efficiency of blank manufacturing when cutting blanks from a metal strip fed in the line direction from an uncoiler using laser light. [Solution] The blank 4 manufacturing apparatus 1 is a blank 4 manufacturing apparatus 1 that cuts out a blank 4 from a metal strip 2 sent from an uncoiler 5 to a line direction LD using laser light 3, and comprises a first laser light irradiation head 11 that forms through holes 7 in the metal strip 2 with laser light 3, and a second laser light irradiation head 12 that moves the irradiation position of the laser light 3 from the position of the through holes 7 to cut out a blank 4 from the metal strip 2, wherein the formation of through holes 7 by the first laser light irradiation head 11 and the cutting out of the blank 4 by the second laser light irradiation head 12 are performed in parallel.
