ABSTRACT:
Apparatus for the continuous production of half hard copper tubing wherein the copper tubing is fed from a roll to a tube storage means in which a continuous length of tube is stored in one or more lengths in such a manner that the front end of the tube can be drawn rapidly from the storage means while the tail end of the tube remains stationary, a movement of the tail end of the tube is arrested, the front end of a further coil of tubing is joined to the stationary tail end of the tube in the storage means as the front end of that tube is fed forward, and the movement of the tail end of the tube restarted. The above operation is carried out while feeding tubing from the storage means continuously and sequentially through an induction annealing furnace, through quenching means and thereafter to a draw finishing or coiling line.
