Abstract

Abstract A METHOD OF ASSEMBLING A PLURALITY OF PAPER CUPS IN TRAY FORMATION AND GLUING THEM TOGETHER IN SAID ASSEMBLED RELATION TOGETHER WITH APPARATUS FOR CARRYING OUT THE METHOD. THE METHOD CONSISTS ESSENTIALLY OF THE STEPS OF: ARRANGING A PLURALITY OF PAPER CUPS IN A SERIES OF TRAY UNITS, EACH OF A PREDETERMINED CUP NUMBER AND FORMATION, MOVING SAID TRAY UNITS THROUGH A GLUING STATION AT WHICH THE CUPS ARE HELD IN POSITION RELATIVE TO ONE ANOTHER; APPLYING GLUE TO ENGAGING CUP PORTION PORTIONS; AND DISCHARGING FINISHED TRAYS. THE APPARATUS COMPRISES, AS CHARACTERISTIC ELEMENTS AN ENDLESS CONVEYOR; CUP RECEIVING PLATES CARRIED BY THE CONVEYOR; A GLUING STATION INCLUDING A SUPPLY OF HEATED GLUE BELOW THE UPPER PLY OF OF THE CONVEYOR, DEVICES FOR HOLDING CUPS IN POSITION IN THE PLATES WHILE GLUE IS APPLIED, AND GLUE APPLYING MEANS IN THE FORM OF A GANG OF UPRIGHT PILE COATED WIRES; MEANS FOR INDEXING THE CONVEYOR WITH A STEPPED MOTION; MECHANISM FOR OPERATING THE CUPS HOLDING DEVICES AND GLUE APPLYING MEANS IN PROPER RELATION TO MOVEMENT OF THE CONVEYOR, AND A BLOCK OUT DEVICE FOR RENDERING THE GLUING MEANS INEFFECTIVE ON CERTAIN PREDETERMINED STEPS TO PROVIDE TRAYS IN A SEPARATED STATE.
