If the actual effective width of cutting positive foil is not more than 480mm, and the actual effective width of cutting negative foil is not more than 490mm, the amount of scrap edge on both sides shall be uniform, and the width error of scrap edge on both sides shall be within ± 1.5mm, so as to ensure that the specific capacitance dispersion difference of normal cutting aluminum foil will not be too large. Edge foil scrap at both ends shall not be used for cutting.<br>
