ABSTRACT:
This disclosure relates to a jet soldering apparatus for applying a jet of solder to a side seam of a can body formed in a bodymaker. The soldering apparatus includes a heated metal block having an elongated cavity which terminates in a discharge orifice. Solder wire is fed into the cavity and is heated therein by means of electrical heaters connected to the block. The cavity has an inlet in the form of a bore which substantially corresponds to the diameter of the solder wire so that the solder wire prevents any back flow of molten solder through the inlet. The cavity is also in the form of a bore generally conforming to the diameter of the solder wire and is of a length to make certain that the solder wire is fully melted before it reaches the discharge orifice. Feed means are provided to intermittently feed the solder wire in accordance with the presentation of a can body to the discharge orifice. The feed means include a reciprocating chuck and a staionary chuck which act in unison. The reciprocating chuck is driven by a cam actuated by the drive system of the bodymaker. Further, there is incorporated in the system means for moving the reciprocating chuck out of the effective range of the cam so that the solder feeding mechanism may be selectively rendered inoperative.
