Abstract

There are provided a cutter attached thereto, a method of and an apparatus for manufacturing the same cutter and attaching the same cutter to the carton. A nonmetallic cutter formed of a hard paper and having saw tooth-shaped edges at one end thereof which is formed by punching thereof. A wrap web containing carton for containing therein a wrap web wound in a roll shape comprises a carton body having an opening through which the wrap web is drawn out, and a nonmetallic cutter attached to the carton body at the position where the wrap web is cut wherein said nonmetallic cutter is formed by punching a hard paper and wherein said nonmetallic cutter cuts the wrap web. A method of attaching a nonmetallic cutter to a carton comprises a steps of feeding intermittently a nonmetallic sheet by a feeding means toward upper and lower molds, one of which is vertically movable, punching the nonmetallic sheet by said upper and lower molds to form a cutter, conveying and setting cartons one by one by a conveying means, and pressing the cutter to the carton at a given position of the carton by way of an adhesive paste applied to the cutter while the cutter is sucked and held by said movable upper or lower mold. An apparatus for manufacturing a cutter and attaching the same cutter to a carton comprises a conveying device for conveying a carton to which a nonmetallic cutter is attached, a pasting device for applying an adhesive paste to the carton at a given position thereof, a cutter manufacturing and pasting device for severing a sheet continuously fed thereto and pasting said severed sheet to a pasting portion of the carton, a cutter roller having a cutter blade which extends substantially axially thereof so as to protrude radially outwardly from said cutter roller, said cutter blade having edges shape of which is same, when viewed toward the edges, as that of edges of a cutter to be manufactured, when viewed on the plane thereof, and a suction roller having a flat surface for receiving said cutter blade and suction holes for sucking and holding the severed nonmetallic cutter, said suction roller being arranged in parallel with and rotated synchronously with said cutter roller, and said suction roller being positioned at the position where the nonmetallic cutter which is sucked and held by said suction holes is pasted to the carton which is conveyed by said conveying device.
