Abstract
Apparatus for conveying paperboard carton blanks through stations including means operative sequentially to fold the blanks about suitably scored lines into set-up tubular carton shells, including end closure flaps, about a mandrel extending along the line of blank travel, and means for rotationally transferring the set-up carton shells to carton filling and closing apparatus. Means is provided at a suitable one of the stations for applying adhesive to side flap portions of the folded blanks to retain their set-up modes as tubular carton shells.
Claims7
Apparatus for forming carton blanks into tubular carton shells each having at least one shell sealing flap on a lateral portion thereof, comprising;
- means defining serially disposed stations through which said carton blanks sequentially may be moved;
- incrementally driven conveyor means for moving said carton blanks through said stations with a pause at each said station;
- means defining a mandrel extending along the path of movement of said conveyor means, and on which said carton blanks are formed into carton shells;
- means for sequentially forming shells on said mandrel as said carton blanks are moved by said conveyor means;
- carton blank feeding means for delivering individual carton blanks to said conveyor means upon incremental drive thereof;
- said conveyor means comprising first and second sections extending in substantially parallel, mutually spaced relation in the direction of the recited path of travel, said first section extending between said blank feeding means and the upstream end of said mandrel, said second section extending between said blank feeding means and the downstream end of said mandrel;
- and means disposed along the path of travel of said conveyor means for adhering said sealing flaps to seal said carton shells.
