Abstract: 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.

Abstract: A film fin sealing device is disclosed herein which may have a groove defining a base. The base of the groove of the fin sealing device may be oriented at a skewed angle with respect to a longitudinal direction of the conveyor of a heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the film fin sealing device and placed in contact therewith to both heat and fuse the distal edge portions of the thermoplastic sheet(s) to join the edge portions thereof to form a fin seal.

Abstract: A case erector system comprises a track, a mounting assembly slidably affixed to the track, a picker and erector assembly removably and reversibly affixed to the mounting assembly, an erector arm in the picker and erector assembly configured to engage a first side of a case, and a picker arm in the picker and erector assembly configured to engage a second side of the case, wherein the erector arm is configured to move to a position generally transverse to the picker arm while both the picker arm and erector arm engage the case unit.

Abstract: A heat shrink tunnel with width adjustment includes a pair of opposing side wall assemblies, each assembly including an outer wall and an inner perforated wall defining a plenum therebetween. The opposing side walls define a product path therebetween having a longitudinal axis. The side wall assemblies are movable toward and away from the axis. A heater/blower assembly is disposed in each of the opposing side walls, each having an outlet directed into the product path and drawing air from the product path, through its respective plenum. A top wall extends between the pair of opposing side wall assemblies and has an adjustable width to accommodate movement of the side wall assemblies.

Abstract: A center-folded film splicer is disclosed. The splicer comprises a splicer assembly that is adjustably mounted to a wrapping device such that it can be moved between a storage position and an operating (or splicing) position. The splicer assembly comprises a pair of heat bars, an upper heat bar and a lower heat bar, connected with a synchronized hinge and a back-up pad bar disposed therebetween. In this manner, the upper and lower layers (or “legs”) of the films from a depleted film roll and a fresh film roll can be simultaneously sealed to each other to create a continuous film that does not need to be rethreaded through the wrapping device when replacing film rolls.
