Definitions
- This invention relates to an adaptable shrink tunnel that directly applies hot air to specific portions of heat shrinkable film in a
- shrinkable film is well known, the properties of the film allowing it to be wrapped around articles before shrinking and thereafter to be shrunk
- tray or not may be heated to shrink the film and bring it into tight
- the film is wrapped around the articles and, if included, the tray enclosing the articles, until there is an overlap seam of the two
- bullseyes at the laterally opposed ends of the multi-packs where the tube openings had been prior to shrinkage.
- any printing (letters, numbers, logos, etc.) on the film will be distorted and the package will be unattractive. If anything
- Hot air is directed upwardly from below the
- the position of the nozzles may be adjusted to accommodate packages of differing widths.
- the ends of the film tube are particularly acute in packaging machines that are alternatively operable as a single lane machine, which requires nozzles directed at two package ends, or as a dual lane
- hot air must be supplied and delivered between lanes of packages so that uniform heat shrinkage at both laterally opposed
- packaging machine is operating in a single lane mode, dual lane mode, or multiple lane mode.
- packaging machine having an adjustable shrink tunnel to accommodate single lane packaging, dual lane packaging or multiple
- laterally adjustable plenums to accommodate differing widths of packages by applying hot air to the laterally opposed ends of packages.
- shrink tunnel for use with a packaging machine that provides
- adjustable plenums to accommodate single lane packaging or multiple
- shrink tunnel providing for the controlled application of hot air directly at laterally opposed ends of packages being processed to create
- the present invention comprises a shrink tunnel associated with
- the shrink tunnel has multiple zones comprising an ambient air pre-shrink zone and a controlled heat zone,
- shrink tunnel is adaptable to provide controlled heating and shrinking
- the shrink tunnel of the present invention comprises means for

- multi-packs 52,54 each having bullseyes in laterally opposed ends
- the present invention may be used with or without a tray or trayforming
- a machine that is adaptable to package articles in either single lane mode, as shown in Figure 1 , or in dual lane mode, as
- invention controls the application of hot air to heat shrinkable film
- shrink tunnel that is flexible and can be converted and used with
- packaging machines that are operable in a single lane mode of operation, a dual lane mode of operation, or a triple lane mode of
- the shrink tunnel 100 shown generally in Figure 3 illustrates dual lane mode of operation of a packaging machine. Two multi-packs
- the tube of heat shrinkable film formed around each multi-pack 102,104 includes an overlap 106 formed in a
- the finished multi-pack is to lap seal the overlaps 106 together.
- the film thereafter comprises tubes around the articles being packaged that are open at both laterally opposed ends. Means for sealing the overlap
- Hot air produced by blower 122 and heating elements 124 is distributed within zone 120 by ductwork 126 and distribution baffle
- Figure 4 illustrates a single run of ductwork 126 and baffle 128, it is specifically contemplated that more elaborate means for
- distributing heated air in the ambient pre-shrink zone may be
