Abstract
A material to be formed, which is uncoiled by an uncoiler from a coil while controlled against meandering, is adjusted in inclination angle by an approach angle adjuster and guided into a separator-forming mill. The material to be formed is introduced and pressurized between rolls in the mill so as to continuously form a separator. The separator formed by the mill is discharged and tension controlled by a pinch roll device with opposite widthwise ends of the separator being pinched. The separator discharged by the pinch roll device is cut without stopping the same by a flying shear at portions with no passages formed.
