Method of making a tube-to-bag connection
Abstract
Abstract A TUBE-TO-BAG CONNECTION COMPRISING A PLASTIC CONTAINER HAVING A NIPPLE PORTION INTO WHICH A PLASTIC TUBE IS INSERTED. A PROBE TYPE WELDING ELECTRODE IS THEN INSERTED INTO THE END OF THE TUBE TO A POSITION WHEREIN THE TIP PORTION OF THE PROBE IS LOCATED WITHIN THE NIPPLE PORTION OF THE PLASTIC CONTAINER. A PAIR OF OUTER ELECTRODES OR JAW ASSEMBLIES ARE POSITIONED AROUND THE EXTERIOR OF THE NIPPLE PORTION. SUCH JAW ASSEMBLIES ARE COMPRISED OF A PLURALITY OF PLATE MEMBERS HAVING ALIGNED NOTCHES THEREIN. THE PLATES OF THE RESPECTIVE JAW ASSEMBLIES WHEN CLOSED BECOME INTERLEAVED ONE WITH THE OTHER WITH THE EDGES OF THE NOTCHES IN LINE CONTACT WITH THE EXTERIOR SURFACE OF THE NIPPLE. THE WELDING STEP IS PERFORMED BY INTRODUCING A HIGH FREQUENCY WELDING CURRENT BETWEEN THE CENTRAL PROBE ELECTRODE AND THE OUTER JAWS.
