An automatic carton closing machine (similar to that described in Specification 1,144,008), is manually set to seal simultaneously the bottom and top of uniform or random size loaded cartons which are admitted singly by a gate 12 with their top flaps open (i.e. vertical) and their bottom flaps folded (i.e. horizontal) to the driven rollers 506, 507, 507-1 (or other means) of a lift 501 which is lowered (when a carton is halted thereon at position 7 by a paddle 225) until the bottom side flaps 532 (Fig. 11) of the carton swing down under the weight of the load therein to rest on inclined surfaces, e.g. free rollers 531, the carton then being moved forward therealong by a chain conveyer 59, 159, 64-1, 64-2 over an adhesive-applying head 535 controlled to supply adhesive successively to the bottom end flaps 538-1, 538-2 which are then lifted again by the rising flanges 548-1, 548-2, the sealed cartons exiting between undriven rollers 550-1, 550-2 and 552 for the adhesive to set. The head 535 may be a spray nozzle for wet glue or of contact type for melted thermoplastic adhesive. The inclined surfaces are formed by rollers 531 (or continuous plates or spaced teeth) and are carried by transversely reciprocable rails 80A, 180A (or by means moving in unison therewith) which initially clamp the carton at position 7 and subsequently guide it (as described in Specification 1,144,008). The lift 501 supporting the driven rollers 506 &c. is moved vertically by a pneumatic motor 526 having a piston-rod 525 which actuates elevating cranks 519 by way of levers 523, 522, 524, 521 and rotatable shafts 516, 515. The rollers 506 &c. support spur gears 508, 509 engaged by an endless chain 511 driven via a spur gear 512, chain 514-1 and chain 42 by the main motor 51 which drives the conveyer chains 59, 159. The rails 80A, 180A are mechanically connected to adhesive-delivery switches 555 and 558 (operated by the passage of carton) so as to move them in relation to fixed delivery switches 556, 557 according to the width of the carton. The switches 555 and 558 are mounted on toothed racks 564, 565 which engage a common pinion 573 rotated by a fixed chain 575 as the rails 80A, 180A move in either direction, to move the racks in opposite directions. The switches 555, 556, 557 and 558 are arranged in a circuit so controlling a pair (or one) of delivery solenoid valves that adhesive is applied to the bottom and top end flaps, and not to the load, as a consequence of the side and end flaps being of the same width. Closing of the top flaps is effected as described in Specification 1,144,008, but adhesive is supplied to the top end flaps by a spray nozzle 536. Chains 59, 159 carry carton transporting flight bars 64-1, 64-2 and tripping lugs 66-1, 66-2, 166-1, 166-2 for operating limit switches.
