Appl. No.:

10/994691

Assignee:

Shrink Packaging Systems Corporation - Nashua NH

International Classification:

B65B 51/10
B65B 7/02

US Classification:

53479, 53460, 533743, 533737

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 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. In one embodiment, nip pressure is generated by nip rollers on the scrap side of the film, and by low friction belt support guides on the package side of the film. In another embodiment, the belt support guides are replaced with a series of upper and lower nip rollers, and adjustable toggle clamps provide adjustable pressure on the series of upper and lower nip rollers.

International Classification:

B65H 4528

B65H 4700
B65H 4564

US Classification:

493355

Abstract:

A paper box folding and sealing machine for forming a hemmed edge. A skiving station removes a portion of a carton blank material at the area to be hemmed. A hemming station folds the skived portion onto the blank, irons it and then opens the hem to lie in a predetermined plane that intersects the plane of the blank. Superheated air directed in a laminar-like air flow, activates a thermoplastic coating adjacent the skived portion of the area to be hemmed. Folding fingers, tack rollers and presser rollers then fold the skived portion onto the activated thermoplastic coating to form a hem that is sealed against the adjacent portion of the blank.

US Classification:

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. A specific embodiment includes two folding stations and the control system for operating these stations independently.
