ABSTRACT:
Automatic carton closing machine equipped with a swingable stop paddle between a bottom prone position allowing carton advance thereover; an upright carton stopping position in the carton advancing path; and an intermediate oblique upwardly and forwardly sloping ramp position for guiding up and forward over an adhesive applicator head the upfolded bottom end flaps when dropping down because of carton contained load thereon. Specific operating mechanism which may be preferred can be pneumatically driven manipulator means so controlled and governed as to provide when desired relatively slow swinging rise from the prone position to the upright position as the clamping side guide rails separate to receive therebetween an oncoming loaded carton and then inward to opposite sides of the latter with strong clamping action as the upright stop paddle stops this carton. This preferred mechanism may then retract this stop paddle quickly to its prone position for further carton advance with conversion of the clamping force of the side rails to advance-permitting guidance. And finally in one cycle of operation on a single loaded carton as the latter advances through the machine it will desirably raise this stop paddle quickly to its intermediate sloping ramp position for performing its end flaps guiding service.
