Abstract
An apparatus for attaching insert panels to carton blanks including a carton blank conveyor for moving carton blanks along a predetermined displacement path; a carton blank folder positioned at a fixed station along the displacement path for folding a leading end panel portion of each passing carton blank for providing an abutment surface for engaging a carton insert panel; an insert panel applicator positioned at a fixed station along the displacement path for applying an insert panel to each passing carton blank; a registration assembly for urging a leading edge portion of each insert panel into abutment with the abutment surface on each folded leading end panel portion.
Claims20
An apparatus for attaching insert panels to carton blanks comprising:
- carton blank conveyor means for moving carton blanks along a predetermined displacement path so that each carton blank has a leading edge portion and a trailing edge portion;
- each carton blank having at least a plurality of leading end panel portions and a plurality of sidewall panel portions;
- carton blank folder means located along said displacement path for folding at least one of said leading end panel portions of each passing carton blank for providing an abutment surface;
- insert panel applicator means positioned along said displacement path for applying an insert panel to each passing carton blank;
- said insert panel having a leading edge portion and a trailing edge portion;
- and
- registration means for urging said leading edge portion of each insert panel into abutment with said abutment surface on said at least one of said leading end panel portions.
A method of preparing a plurality of flat carton blanks and flat insert panels for folding and gluing into reinforced carton configurations comprising the steps of:
- moving the carton blanks along a predetermined displacement path so that each carton blank has a leading portion and a trailing portion;
- deforming at least one leading end panel portion of each carton blank to provide an abutment surface projecting transversely of the direction of carton displacement;
- moving an insert panel along said displacement path;
- placing each insert panel in a predetermined registration position with an associated carton blank by urging a predetermined edge portion of each insert panel into abutting relationship with said abutment surface on an associated carton blank;
- fixedly attaching each registeringly positioned insert panel to each associated carton blank.
