Apparatus for manufacture of containers

Claim 1

AN APPARATUS FOR MAKING CONTAINERS AT A HIGH RATE OF SPEED FROM THIN WALL CONTAINER BODIES, EACH CONTAINER BODY HAVING AN OPEN END, AND COVERS, EACH COVER SHAPED TO FIT OVER SAID OPEN END ON SAID CONTAINER BODY, ONE OF SAID CONTAINER BODY AND SAID COVER HAVING A CURL AROUND ITS FREE END AND THE OTHER HAVING A CORNER AT ITS FREE END WHICH FITS AGAINST AN AREA IN SAID CURL; SAID APPARATUS COMPRISING SYNCHRONIZED ROTATABLE TURRETS HAVING A PLURALITY OF STATIONS SPACED AROUND THE AXIS OF EACH OF SAID TURRETS, EACH OF SAID STATIONS OF A FIRST ROTATABLE TURRET COMPRISING A PAIR OF OPPOSING ELECTRICALLY CONDUCTIVE HEADS AT LEAST ONE OF WHICH IS MOVABLE TOWARDS THE OTHER, ONE OF SAID HEADS BEING SHAPED TO FIT AGAINST SAID COVER AND THE OTHER OF SAID HEADS BEING SHAPED TO FIT AGAINST SAID CONTAINER BODY; COVER FEED MEANS FOR FEEDING ONE OF SAID COVERS TO A POSITION RELATIVE TO SAID HEAD OF SAID FIRST TURRET CORRESPONDING THERETO IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES; SECOND ROTATABLE TURRET MEANS FEEDING SAID CONTAINER BODIES ONE AT A TIME FROM A PLURALITY OF STATIONS TO A POSITION RELATIVE TO SAID HEAD OF SAID FIRST TURRET CORRESPONDING THERETO IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES; CAM MEANS FOR MOVING ONE OF SAID HEADS TOWARDS THE OTHER IN EACH OF SAID STATIONS OF SAID FIRST TURRET AT A PLACE LATER IN ROTATION THAN THE COVER AND CONTAINER BODY FEEDING MEANS TO ENABLE SAID HEADS TO HOLD SAID COVER AGAINST SAID CONTAINER BODY UNDER A POSITIVE PRESSURE IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES A TRANSFORMER ROTATABLY MOUNTED ALONG WITH SAID FIRST TURRET AND CONNECTED TO A SOURCE OF ELECTRICITY ON ONE SIDE THEREOF AND TO SAID HEADS IN EACH OF SAID STATIONS OF SAID FIRST TURRET ON THE OTHER SIDE THEREOF, SAID TRANSFORMER BEING ENERGIZABLE TO SUPPLY AN ELECTRIC CURRENT ACROSS THE JUNCTION BETWEEN SAID COVER AND SAID CONTAINER BODY WHILE UNDER POSITIVE PRESSURE TO FUSE SAID COVER TO SAID CONTAINER BODY IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST AND SECOND TURRETS ROTATE TO FORM A SUCCESSION OF SAID CONTAINERS; AND THIRD ROTATABLE TURRET MEANS HAVING A PLURALITY OF STATIONS FOR REMOVING SAID CONTAINERS FROM SAID STATIONS OF SAID FIRST TURRET AS SAID TURRETS ROTATE SYNCHRONOUSLY.

Claim 2

AN APPARATUS FOR MAKING CONTAINERS AT A HIGH RATE OF SPEED FROM THIN WALL CONTAINER BODIES, EACH CONTAINER BODY HAVING AN OPEN END, AND COVERS, EACH COVER SHAPED TO FIT OVER SAID OPEN END ON SAID CONTAINER BODY, ONE OF SAID CONTAINER BODY AND SAID COVER HAVING A CURL AROUND ITS FREE END AND THE OTHER HAVING A CORNER AT ITS FREE END WHICH FITS AGAINST AN AREA IN SAID CURL; SAID APPARATUS COMPRISING SYNCHRONIZED ROTATABLE TURRETS HAVING A PLURALITY OF STATIONS SPACED AROUND THE AXIS OF EACH OF SAID TURRETS, EACH OF SAID STATIONS OF A FIRST ROTATABLE TURRET COMPRISING A PAIR OF OPPOSING ELECTRICALLY CONDUCTIVE HEADS AT LEAST ONE OF WHICH IS MOVABLE TOWARDS THE OTHER, ONE OF SAID HEADS BEING SHAPED TO FIT AGAINST SAID COVER AND THE OTHER OF SAID HEADS BEING SHAPED TO FIT AGAINST SAID CONTAINER BODY; COVER FEED MEANS FOR FEEDING ONE OF SAID COVERS TO A POSITION RELATIVE TO SAID HEAD OF SAID FIRST TURRET CORRESPONDING THERETO IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES; SECOND ROTATABLE TURRET MEANS FEEDING SAID CONTAINER BODIES ONE AT A TIME FROM A PLURALITY OF STATIONS TO A POSITION RELATIVE TO SAID HEAD OF SAID FIRST TURRET CORRESPONDING THERETO IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES; CAM MEANS FOR MOVING ONE OF SAID HEADS TOWARDS THE OTHER IN EACH OF SAID STATIONS OF SAID FIRST TURRET AT A PLACE LATER IN ROTATION THAN THE COVER AND CONTAINER BODY FEEDING MEANS TO ENABLE SAID HEADS TO HOLD SAID COVER AGAINST SAID CONTAINER BODY UNDER A POSITIVE PRESSURE IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST TURRET ROTATES A TRANSFORMER ROTATABLY MOUNTED ALONG WITH SAID FIRST TURRET AND CONNECTED TO A SOURCE OF ELECTRICITY ON ONE SIDE THEREOF AND TO SAID HEADS IN EACH OF SAID STATIONS OF SAID FIRST TURRET ON THE OTHER SIDE THEREOF, SAID TRANSFORMER BEING ENERGIZABLE TO SUPPLY AN ELECTRIC CURRENT ACROSS THE JUNCTION BETWEEN SAID COVER AND SAID CONTAINER BODY WHILE UNDER POSITIVE PRESSURE TO FUSE SAID COVER TO SAID CONTAINER BODY IN EACH OF SAID STATIONS OF SAID FIRST TURRET AS SAID FIRST AND SECOND TURRETS ROTATE TO FORM A SUCCESSION OF SAID CONTAINERS; AND THIRD ROTATABLE TURRET MEANS HAVING A PLURALITY OF STATIONS FOR REMOVING SAID CONTAINERS FROM SAID STATIONS OF SAID FIRST TURRET AS SAID TURRETS ROTATE SYNCHRONOUSLY.
