Disclosed is an apparatus for manufacturing a tab of a beverage can, in which, while the tab of the beverage can of which curling part is closed to provide a space to apply a design is being formed, the tab coil is pressed by the pilot pins pressed by springs in the casing so as to prevent the free movement of the tab, and the pressing force of the pilot pins against the tab can be changed to maintain a proper pressure usually by adjusting the length of the pilot pins. The tab manufacturing apparatus has a pilot pin (24) installed downward vertically on the upper mold (20), the pilot pin (24) for preventing a movement of the tab placed on the lower mold (30); a casing (40) installed on the upper mold (20); a spring (42) accommodated in the casings (40), the spring (42) for pressing the pilot pin (24); and an adjusting bolt (44) screwedly assembled with an upper part of the casing (40) the adjusting bolt (44) for adjusting an elastic force of the spring (42). |
