Abstract: A method and an arrangement for the packaging of a material-web roll, includes the roll being surrounded on all sides by packaging material. The packaging material is closed by a pleating device for the pleating of the axial projections of the packaging material on the end faces of the roll. A device for applying the outer end face covers is also included. When packaging the roll, air is enclosed within the package which often results in a bursting of the package when the roll is being deposited on one of its end faces. To avoid this bursting, a portion of the air mass is removed from the interior of the packaging material and after closing the package, the volume of the still enclosed air is being reduced by the provision of a heating device for heating at least a portion of the air volume being enclosed by the packaging.

Abstract: An apparatus and method for filling liquid-phased extruded containers comprises injecting the extruded material into a die head forming a tubular shape. The die head is hollow, or bored, from its back end to its front where the extruded material egresses to form the extrudate (pre-container) tube shape. A means for introducing a separable insert through the die head bore permits the insert to be encased within the tube while the thermoplastic material is still in its liquid or molten phase. Pinch rollers seal the tube at ends opposite that of the insert while avoiding the insert, while the line of sealed containers is pulled by gear rollers through a water cooling bath. A die punch stamp cuts the pinched, or sealed, sections of the containers separating them into individual, filled, singular units.

Abstract: Frozen dessert cones made from a cooked batter capable of having lower and higher moisture contents, which respectively cause the cone to assume dimensionally contracted and expanded states, are provided with sanitary jackets while in their dimensionally contracted state. When the cooked batter forming the cone attains a higher moisture content, the cone will dimensionally expand against the walls of the sanitary jacket thereby exerting a restraining force against removal of the jacket from the cone. The sanitary jacket is applied to an interior handle region of a cone so that the sanitary jacket will nest with the exterior surface of a downstream cone handle when stacked therewithin. A chute is provided so as to align and direct the sanitary jacket with respect to the interior handle region of the cone. A stream of pressurized fluid (e.g., air) is then preferably directed against the sanitary jacket so as to propel the same into a seated relationship with the interior handle region.
