Abstract: A side sealing apparatus for a shrink packaging machine comprising closed loop temperature control of a heater for maintaining an optimum temperature for cutting and sealing two layers of thermoplastic film. The heater comprises a cable or cartridge heater with an internal thermocouple, and it is connected to an automatic temperature controller. The heater is mounted on the side sealer apparatus between two sets of top and bottom V-belts mounted around drive rolls and idler rolls. The V-belts provide nip pressure against the film in order to drive the film. Nip pressure is generated by nip rolls on the scrap side of the film, and by belt support plates on the package side of the film.

Abstract: A surveillance tag applicator for applying tags to articles such as box blanks, blister cards, or containers at very high rates of speed up to and greater than 1000 tags per minute. The applicator comprises a plurality of tags attached to a web fed to a rotating drum having a plurality of slots, a compression roller for pressing each of the tags into one of the plurality of slots, an ejector arm for ejecting each tag from the slots onto a selected location of an article passing by the drum, a stripper to remove the web from the tags, and a winder assembly for rewinding the web devoid of tags. A first servo motor drives the rotating drum and a second servo motor drives the ejector arm. A controller provides the timing and control for the servo motors and operation of the tag applicator.

Abstract: Apparatus for a paper box folding machine for folding the trailing panels of carton blanks about fold lines as the blanks travel individually and successively along a paper line. A servomotor running continuously at a relatively constant nominal angular velocity drives the input shaft to an indexer that controls, for each position of its input shaft, the angular position of its output shaft. The indexer converts continuous input from the servomotor to discontinuous motion of its output shaft. The output shaft lies below and transverse to a paper line. Radially extending fingers mounted on the output shaft are positioned below a trailing panel as the carton blank passes. The indexing means output shaft and fingers rotate rapidly so the fingers engage and fold the trailing panel and then dwell to allow the blank to exit the apparatus. Then the shaft and fingers move below the paper line to allow another blank to enter and rotate to engage a next blank in sequence.
