Abstract
An improved method for forming tray, boat, tray, boat, and/or clamshell type, paperboard, cartons that have horizontal main wall panels and side wall panels, with corner flaps, joined to the main wall panels and extending therefrom and adhesively secured to each other. The cartons are formed from rolls or sheets of paperboard wherein the cutting, stripping, gluing, and forming operations are performed in a completely inline operation.
Claims13
A method of forming, from paperboard, on equipment in a completely inline operation, a plurality of clamshell type cartons, each of said cartons including a pair of hingedly interconnected body and cover members, and each of said members including a horizontal main wall panel and a plurality of side wall panels, with corner flaps, extending therefrom and adhesively secured to each other, said method comprising the steps of:
- (a) positioning said paperboard at a loading station of said equipment;
- (b) moving said paperboard from said loading station, to a cutting and scoring station;
- (c) die cutting and scoring said paperboard, at said cutting and scoring station, to provide a plurality of interconnected carton blanks;
- (d) moving said plurality of interconnected blanks from said cutting and scoring station to a combination stripping and gluing station:
- (e) simultaneously stripping waste material from said plurality of interconnected blanks and applying adhesive to pertinent areas of said blanks at said stripping and gluing station;
- (f) moving said plurality of interconnected blanks from said stripping and gluing station to a forming station;
- (g) at said forming station, separating said plurality of interconnected blanks from each other and moving said horizontal main panels of the members of each of said pairs toward each other;
- and
- (h) forming cartons from said separated blanks by applying forming heads to said separated blanks to engage said separated blanks and push them through forming chambers and into cavities of previously formed and stacked cartons, which cavities hold said cartons until previously applied adhesive has set.
A method of forming, from paperboard, on equipment in a completely inline operation, a plurality of tray type cartons, each of said cartons including a body member including a horizontal main wall panel and a plurality of side wall panels, with corner flaps, extending therefrom and adhesively secured to each other, said method comprising the steps of:
- (a) positioning said paperboard at a loading station of said equipment;
- (b) moving said paperboard from said loading station, to a cutting and scoring station;
- (c) die cutting and scoring said paperboard, at said cutting and scoring station, to provide a plurality of interconnected carton blanks;
- (d) moving said plurality of interconnected blanks from said cutting and scoring station to a combination stripping and gluing station:
- (e) simultaneously stripping waste material from said plurality of interconnected blanks and applying adhesive to pertinent areas of said blanks at said stripping and gluing station;
- (f) moving said plurality of interconnected blanks from said stripping and gluing station to a forming station, and, at said forming station, separating said plurality of interconnected blanks from each other;
- and
- (g) forming cartons from said separated blanks by applying forming heads to said separated blanks to engage said separated blanks and push them through forming chambers and into cavities of previously formed and stacked cartons, which cavities and hold said cartons until previously applied adhesive has set.
A method of forming, from paperboard sheets, on equipment in a completely inline operation, a plurality of clamshell type cartons, each of said cartons including a pair of hingedly interconnected body and cover members, and each of said members including a horizontal main wall panel and a plurality of side wall panels, with corner flaps, extending therefrom and adhesively secured to each other, said method comprising the steps of:
- (a) positioning said paperboard sheets in a vertical stack at a loading station of said equipment;
- (b) moving said sheets from said loading station, to a cutting and scoring station;
- (c) die cutting and scoring said sheets, at said cutting and scoring station, to provide a plurality of interconnected carton blanks;
- (d) moving said plurality of interconnected blanks from said cutting And scoring station to a combination stripping and gluing station:
- (e) simultaneously stripping waste material from said plurality of interconnected blanks and applying adhesive to pertinent areas of said blanks at said stripping and gluing station;
- (f) moving said plurality of interconnected blanks from said stripping and gluing station to a forming station;
- (g) at said forming station, separating said plurality of interconnected blanks from each other and moving said horizontal main panels of the members of each of said pairs toward each other;
- and
- (h) forming cartons from said separated blanks by applying forming heads to said separated blanks to engage said separated blanks and push them through forming chambers and into cavities of previously formed and stacked cartons, which cavities hold said cartons until previously applied adhesive has set.
A method of forming, from a paperboard roll, on equipment in a completely inline operation, a plurality of clamshell type cartons, each of said cartons including a pair of hingedly interconnected body and cover members, and each of said members including a horizontal main wall panel and a plurality of side wall panels, with corner flaps, extending therefrom and adhesively secured to each other, said method comprising the steps of:
- (a) positioning said paperboard roll at a loading station of said equipment;
- (b) moving said paperboard from said roll at said loading station, to a cutting and scoring station;
- (c) die cutting and scoring said paperboard, at said cutting and scoring station, to provide a plurality of interconnected carton blanks;
- (d) moving said plurality of interconnected blanks from said cutting and scoring station to a combination stripping and gluing station:
- (e) simultaneously stripping waste material from said plurality of interconnected blanks and applying adhesive to pertinent areas of said blanks at said stripping and gluing station;
- (f) moving said plurality of interconnected blanks from said stripping and gluing station to a forming station;
- (g) at said forming station, separating said plurality of interconnected blanks from each other and moving said horizontal main panels of the members of each of said pairs toward each other;
- and
- (h) forming cartons from said separated blanks by applying forming heads to said separated blanks to engage said separated blanks and push them through forming chambers and into cavities of previously formed and stacked cartons, which cavities hold said cartons until previously applied adhesive has set.
