Abstract
Abstract A device for use in manually handling shipping cartons include transfer rails having vertical entrance ends which curve into horizontal portions downstream for closing the transversely connected carton bottom flaps. A gluing assembly below the rails is actuatable, at a minimum, by the downward springback of said flaps to apply glue thereto. The glue applicator head is pivotally mounted to assure uniform glue application. A plow closes the longitudinally connected carton bottom flaps, and the still empty carton moves into a packing station which includes gripping means for holding the carton against vertical movement due to spring-back of the bottom flaps. The carton is packed, the top flaps are then closed and glued, and the carton moved through a compression section.

Claim 1
Independent Claim
221 words
In a device for use in manually handling an opened shipping carton having a carton body, a first pair of opposed transversely connected bottom flaps, and a secoNd pair of opposed longitudinally connected bottom flaps: a. transfer rail means having an entrance end portion of generally vertical extent which merges through a gradually curved portion to a generally horizontal downstream portion, b. said curved portion comprising means for initiating the tucking in of said first pair of flaps, c. said downstream portion comprising means for completing the tucking in of said first pair of flaps and for supporting a carton moved therealong, d. applicator means disposed below said downstream portion for applying glue to said tucked-in first pair of flaps, e. plow means for subsequently tucking in said second pair of flaps onto said glue-applied first pair, f. and means proximate the discharge end of said transfer rail means for gripping the carton body to prevent vertical movement of the carton, said gripping means comprising: 1. a horizontal guide plate member over which the carton travels, 2. a stop bar member disposed parallel to said plate, 3. said members forming a channel normally slightly narrower than the carton width, 4. and spring means on at least one of said members for biasing the latter against a carton disposed between the members.
