摘要： A shrink wrapping apparatus, and associated process, includes a housing (turbine) having a wall forming a passage dimensioned to receive the associated container assembly and associated sleeve. The passage has an inlet and an outlet spaced therefrom. A steam/hot air path communicates with the passage to provide steam from an associated steam source to at least a portion of the passage in order to shrink wrap the associated sleeve on the associated container assembly as the container assembly and sleeve move through the passage. The apparatus also includes a stop member for engaging the associated container assembly and holding in the passage for a predetermined amount of time.

摘要： Systems and methods for shrink wrap bundling a group of heat-sensitive products are provided. A method comprises: providing a heating oven with a convective heat source and a radiant electromagnetic energy source therein and a product; and wrapping the product with a shrink film that comprises an activation temperature and an electromagnetic energy absorbance level. The method also comprises: placing the wrapped product inside the heating oven for a predetermined duration of residence time; exposing the wrapped product to radiant electromagnetic energy for a predetermined duration of exposure time, wherein the direction of the electromagnetic energy is coincidental or approximately coincidental with a plane of the shrink film; and removing the wrapped product from the heating oven resulting in the wrapped product being robustly bundled according to a defined Bundle Rigidity Test without substantial damage to the heat-sensitive products of the wrapped product.

摘要： An apparatus for shrinking film onto products moving along a conveyance path includes an elongated steam chamber shaped to form a shrink tunnel through which the conveyance path extends, wherein tunnel side surface portions of the elongated steam chamber bound the path at least in tunnel regions above a plane of the conveyance path and the tunnel side surface portions are heated by steam within the elongated steam chamber and the tunnel side surface portions thereby radiate heat into the shrink tunnel. At least one steam header is positioned within the shrink tunnel and extending along at least part of a length of the shrink tunnel, the steam header including a plurality of steam ejection orifices for ejecting steam into the shrink tunnel. At least one steam flow path feeds steam from an output of the elongated steam chamber to an input of the at least one steam header.

摘要： A shrink wrapping apparatus, and associated process, includes a housing (turbine) having a wall forming a passage dimensioned to receive the associated container assembly and associated sleeve. The passage has an inlet and an outlet spaced therefrom, and the inlet is located vertically above the outlet such that the associated container assembly and associated sleeve move from the inlet toward the outlet. A steam path communicates with the passage to provide steam from an associated steam source to at least a portion of the passage in order to shrink wrap the associated sleeve on the associated container assembly as the container assembly and sleeve move downwardly through the passage and the steam naturally rises upwardly through the passage.

摘要： In an installation for the treatment of containers, comprising at least one filling station and a packing station for processing film or packaging material blanks and having work components acting upon the packaging material and forming packages, at least one measuring device for dimensional deviations of filled containers, and a control unit for automatically adjusting at least one installation station depending on a dimensional deviation detected, work components in the packing station (P) acting upon the packaging material when the filled containers are packed are automatically adjustable by way of the control unit. In a method for packing filled containers, work components of the packing station acting upon packaging material are adjusted automatically depending on dimensional deviations measured in order to form packages of different dimensions with at least substantially the same packing density.

摘要： A heat shrink tunnel with width adjustment includes a pair of opposing side wall assemblies, each including an outer wall and an inner perforated wall defining a plenum therebetween. The opposing side walls define a product path with the side wall assemblies being movable toward and away from each other. A heater/blower assembly disposed in each of the opposing side walls and has an outlet directed into the product path. A shroud extends over the side wall assemblies and an open top space between the side all assemblies. The side wall assemblies extend upwardly toward an inside of the shroud so as to define a small gap between tops of the side wall assemblies and the inside of the shroud. The shroud has a bottom wall. A conveyor is configured to convey items through the heat shrink tunnel. A tunnel includes a side wall assembly width adjusting assembly to move the side walls toward and away from one another by actuation of a single actuator.

摘要： A tray sealer including a sealing station comprising a tool upper part, a clamping frame and a tool lower part. The tool upper part may surround a dome-shaped die used for deforming a skinnable top film. First and second channels in the dome-shaped die and in the tool upper part, respectively, are connectable to one another. The tool upper part or the dome-shaped die may comprise at least a third channel communicating with a vacuum generator so as to generate a thermal air convection from the first channel to the third channel along a side of the top film facing the dome-shaped die.
