Nonmetallic cutter, a carton having the same cutter attached thereto, a method of and an apparatus for manufacturing the same cutter and attaching the same cutter to the carton

An apparatus for manufacturing a cutter comprising:

• a cutter cylinder having a cutter blade provided on a peripheral surface thereof and extending in longitudinal direction thereof;
• a rotary die cutter having a receiving cylinder for receiving said cutter blade;
• a conveying device having a pair of feeding cylinders, said cylinders each having a cylindrical feeding surface on the outer peripheral surface at the partial region thereof in the circumferential direction thereof wherein the nonmetallic sheet is fed between the cutter cylinder and the receiving cylinder of said rotary die cutter at the speed synchronous with that of said cutter blade;
• and
• an inverting device for pulling back the sheet after the tip position thereof is severed by action of the cutter cylinder and the rotary die cutter to form the cutter.

An apparatus for manufacturing a cutter comprising:

• a rotary cutter comprising cutter roller and a receiving roller, said cutter roller including a cutter blade, wherein said cutter blade protrudes radially outwardly from the cutter roller, said receiving roller being disposed in parallel with said cutter roller;
• a feeding device for feeding a nonmetallic sheet between said cutter roller and said receiving roller in a feed direction, wherein said cutter is formed from said nonmetallic sheet;
• and
• said receiving roller including a receiving portion having a flat receiving surface which cooperates said cutter blade to cut said sheet to form said cutter, wherein a plurality of suction holes extend through said receiving surface to hold said cutter which is to be formed by said cutter blade.
