Abstract: A carton formed from a carton blank comprising a unitary sheet of material having cut out portions, cut lines, fold lines and perforations to form various panels which are folded together to form a carton wherein the perforations are located so that a person has a choice of forming an opening from a plurality of locations.

Abstract: An inner container and an outer container folded together to form a container having opposite gusseted side walls, planar front and back walls and a bottom wall comprising portions of the inner and outer containers not adhesively secured together and having a bottom surface comprising portions of the outer container and an outer member adhesively secured to the portions of the outer container forming the bottom surface.

Abstract: A pour spout for a recyclable carton is provided wherein an inner portion of the pour spout is formed from normally waste material and wherein the inner portion is removably attached to a top panel so that when the top panel is moved around its fold line the inner portion is superposed over an outer portion of the pour spout located in a sidewall panel so that when the top panel is unfolded, the inner portion breaks away to remain secured to the outer portion. In one embodiment, a pair of spaced apart side panels are integral with the inner portion to provide sidewalls for the pour spout. In another embodiment, a slide member moves with an intermediate panel in linear directions between locations to allow an opening to be used or to cover the opening.

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.

Abstract: An apparatus for simultaneously inverting a carton blank and folding end flaps thereon includes a system of endless belts, nip rollers, and inversion guides. A blank passes between a first nip assembly and the belts to be fed upwardly between a pair of guides, and withdrawn downwardly and fed out again inverted second nip assembly cooperating with the belts. Flap folders fold flaps on the blank during the operation.

Abstract: A speed control assembly for a rotatable web winding apparatus comprising a dancer engaged with a web of material wound about the winder apparatus for displaceably responding within a predetermined range of dancer positions to tension variations in the web; a first control signal generating device for generating a first control signal in response to dancer displacement from a predetermined centered position, the ratio of dancer displacement to the first control signal being variable over the range of dancer displacement positions; and a dancer response rotation control device for rotationally accelerating the winding apparatus in response to the first control signal.
