VERFAHREN UND VORRICHTUNG ZUM EINTEILIGEN AUSBILDEN EINER SCHNEIDEINRICHTUNG AN EINEM KARTON-ROHSTUECK

摘要

A paperboard shaped into a profile substantially the same as that of a carton blank for folding into a carbon is formed with a plurality of first slits on an edge of the paperboard at a predetermined angle relative to the edge and with a plurality of second slits on the same edge at a predetermined angle relative to the first slits in such a manner that saw-teeth are integrally formed thereon. The saw teeth are immersed in a bath of a quick drying adhesive including (alpha)-cyanoacrylate to be impregnated with the adhesive and then dried, thereby forming teeth constituting a cutter on the carton blank. The carton obtained by folding the carton blank can be used as a packaging container for accommodating a roll of wrapping wed. An apparatus for carrying out the method comprises first cutting means for forming the first slits, second cutting means for forming the second slits so as to integrally form saw-teeth on the edge portion, a bath of adhesive for impregnating the teeth with the adhesive, drying means for drying the teeth, and transfer means for transferring the paperboard along a predetermined path via the first and second cutting means, the bath and the drying means.
