Abstract

A plurality of shapes each having a fundamental construction of a flange are vacuum formed on a continuous sheet of thermoplastic resin. When blanking each of the formed shapes out of the resin sheet into an individual flange, a spool core is placed coaxially with the formed shape placed in the blanking position. The flange just blanked out of the resin sheet is moved in the blanking direction toward the spool core, to be fit on the spool core. The shapes are formed in a double line along the resin sheet, and thereafter, the resin sheet is slit along the longitudinal direction into two sheet branches each having the formed shapes arranged in a single line. The back side surfaces of the two sheet branches are opposed to each other, and the spool core is disposed between the sheet branches and oriented in a direction perpendicular to the back side surfaces of the sheet branches. The formed shapes are blanked out of the sheet branches in opposite directions toward opposite ends of the spool core.
