ABSTRACT:
A bundle squaring machine suitable particularly for squaring a bundle of cartons in readiness for strapping. The machine includes a conveyor system for conveying a bundle of randomly orientated stack of articles into a squaring zone, where the stack is squared-up laterally and fore and aft. While in the squaring zone, side squaring arms close in a lateral direction against the sides of the bundle, and a pusher device moves the bundle longitudinally forward against a pair of spring biased rollers which contact the leading edge of the bundle. Following a period of contact between the leading edge of the bundle and the rollers, the rollers are pivoted clear of the bundle and, thereafter, the side squaring arms move back to their initial position. During the squaring operation the conveyor system is halted, the bundle being advanced by the pusher device during this period, and following the squaring operation, the pusher device is retracted below the level of the conveyor system. An article feed diverter is also provided for use in conjunction with the squaring machine.
