A plough for closing carton flaps, particularly major carton flaps and a process for making the plough. The plough is designed to cause the flaps to close at or near constant velocity so as to minimize disruptions on the manufacturing line. The plough is prepared by generating data describing the coordinates of a flap as it closes at or near constant velocity, using the data to generate additional data describing the contour of a plough necessary to close the flap at or near constant velocity, and causing the plough to be fabricated utilizing the contour data.

Carton closing plough and process

An improved magazine particularly useful for stacking concentrated or superconcentrated detergent cartons and a process for erecting such cartons and other stackable items. Manufacturing problems resulting from the presence of the handle in high density powder cartons can be reduced by use of a magazine or chute having curved side walls, which accommodate the fanning which normally occurs when the cartons are stacked. Flat tubular carton blanks are inserted, preferably horizontally, into a first carton opening in the magazine and travel therethrough to a second, preferably vertical opening in the magazine, where they emerge. The shape of the magazine accommodates the uneven stacking of the cartons which tends to occur because of the extra localized thickness contributed by the carton handle and the rivets. A case turner is provided for feeding cases of cartons into the magazine.

Magazine and process for stacking cartons employing same

A carton for housing sheets, particularly dryer sheets. The dryer sheets are preferably stacked in a 'C' shape and are removed via an access flap which may include 2 hinges and may be reclosable. The ratio of the length of the horizontal axis of the access flap is preferably of a defined ratio to the width of the sheet.

Fabric softener sheet dispenser

A carton for housing sheets, particularly dryer sheets. The dryer sheets are preferably stacked in a 'U' shape and are removed via an access flap which may include 2 hinges and may be reclosable. The ratio of the length of the horizontal axis of the access flap is preferably of a defined ratio to the width of the sheet.
