| 1 | Apparatus and method to lubricate and curl paperboard container rims | US458783 | 1995-06-02 | US6126585A | 2000-10-03 | David W. Norwood; Robert Brown; Edward Earnest |
| Apparatus for lubricating and curling a rim of a paperboard container includes a housing block defining a central recess sized and configured to accept therein a rim of a paperboard container to be curled. An annular curling channel is disposed in the recess for curling the rim of the paperboard container in response to relative advancing movement between the paperboard container and the housing block. The housing block also defines an annular liquid channel concentrically disposed in surrounding relationship to the annular curling channel for distributing lubricating liquid. A porous liquid transfer ring is attached to the housing block in covering relationship to the annular liquid channel so that lubricating liquid supplied to the liquid channel comes into contact with the liquid transfer ring. The liquid transfer ring includes a circular edge surface which defines a central opening such that the liquid transfer ring extends at least partially over the curling channel. In use, the rim of the paperboard container comes into wiping contact with the central opening of the liquid transfer ring so that lubricating liquid is transferred thereto prior to the rim being curled in the curling channel. | ||||||

| Containers and a method for forming such containers having larger brims with reduced brim curl defects is disclosed including providing a plurality of container blanks for forming containers, forming a plurality of container shells from the plurality of blanks, accumulating the plurality of container shells at an accumulation station, subjecting at least an upper periphery of the shells to a humid atmosphere to precondition the shells with the atmosphere preferably including steam, successively removing the shells from the accumulator and subsequently forming a brim curl about an upper periphery of the shell with the shells being subject to the humid atmosphere for a predetermined time period sufficient to form defect-free brim curls by extending the forming strain limits of the paperboard material. This method being carried out by using an accumulator for accumulating the container shells for further processing. Alternatively, the container blanks can be retained in a hopper leaving the portion of the container blank to be formed into the brim of the container exposed. | ||||||

| 6 | Method and apparatus for forming carton blanks with hemmed edges | US917574 | 1992-07-21 | US5236408A | 1993-08-17 | Hugh A. McAdam, III; M. Paul Burnside; Jeffrey Lindberg |
| A paper box folding and sealing machine for forming a hemmed edge. A skiving station removes a portion of a carton blank material at the area to be hemmed. A hemming station folds the skived portion onto the blank, irons it and then opens the hem to lie in a predetermined plane that intersects the plane of the blank. Superheated air directed in a laminar-like air flow, activates a thermoplastic coating adjacent the skived portion of the area to be hemmed. Folding fingers, tack rollers and presser rollers then fold the skived portion onto the activated thermoplastic coating to form a hem that is sealed against the adjacent portion of the blank. | ||||||
