Filed: 1991-11-01
Abstract: PURPOSE:To cut a panel having a notched part on a cutting line without releasing a nozzle of a laser beam cutting device to regulate the height of the nozzle by a capacitive proximity sensor. CONSTITUTION:Thick paper 6 having the almost same shape as the notched part 4 is applied to the notched part 4 on the cutting line of the panel 3 and metal tapes 7 are stuck along the cutting line to both sides including the notched part 4 of the panel 3.
