Abstract

Abstract A HORIZONTAL, CONTINUOUSLY MOVING CONVEYOR ADAPTED TO CARRY NEWSPAPERS INDIVIDUALLY IN A FLAT POSITION TO AN ENVELOPING STATION WHERE THE NEWSPAPERS ARE PACKAGED IN A PROTECTIVE FILM. THE ENVELOPING STATION HAS A TRANSPORT MECHANISM THAT IS ACTUATED RESPONSIVE TO A NEWSPAPER SENSOR LOCATED AT THE CONVEYOR. TWO ROLLS OF PROTECTIVE FILM ARE SUPPORTED ABOVE AND BELOW THE PLANE OF THE CONVEYOR TO ROTATE ABOUT HORIZONTAL AXES SO AS TO FEED FILM TO THE ENVELOPING STATION. THE ENDS OF THE TWO ROLLS OF FILM ARE SEALED TOGETHER ACROSS THE ENTRANCE TO THE ENVELOPING STATION. AS EACH NEWSPAPER APPROACHES THE ENVELOPING STATION, THE SENSOR ACTUATES THE TRANSPORT MECHANISM OF THE ENVELOPING STATION, THEREBY MOVING THE NEWSPAPER THROUGH THE ENVELOPING STATION BEHIND THE SEALED ENDS OF THE TWO ROLLS OF FILM. CONSEQUENTLY, THE FILM ENVELOPS THE TOP AND BOTTOM SURFACES OF THE NEWSPAPER. AFTER THE NEWSPAPER PASSES THE SENSOR, THE TRANSPORT MECHANISM OF THE ENVELOPING STATION STOPS AND A FILM CUTTER AND SEALER IS ACTUATED. THE FILM IS THUS CUT AND SEALED TRANSVERSE TO ITS LENGTH NEAR THE ENTRANCE TO THE ENVELOPING STATION AND IS SEALED ALONG ITS SIDES. ONE TRANSVERSE SEAL IS UTILIZED FOR THE REAR EDGE OF ONE PACKAGED NEWSPAPER AND THE FRONT EDGE OF THE NEXT NEWSPAPER. THE TRANSPORT MECHANISM MOVES THE NEWSPAPER THROUGH THE ENVELOPING STATION AT A FASTER HORIZONTAL SPEED THAN THE CONTINUOUSLY MOVING CONVEYOR.
