ABSTRACT:
Metal strips of indefinite length are made from a plurality of limited-length rolled-strip sections by temporarily clamping adjoining ends of a pair of such strip sections between semi-cylindrical halves of a reel and welding them together while the reel is rotated to wind the two strip sections into a double-layer coil thereon. A trailing end of the second strip section of this pair is then similarly joined to a leading end of a third strip section in another such reel, upstream of the former; as the two reels are rotated in opposite directions, the first strip section is fed forward from the unwinding double-layer coil of the downstream reel while the second strip section is fed back to be wound jointly with the third strip section into another double-layer coil on the upstream reel. In an analogous manner, further strip sections can be joined to the preceding ones with the aid of one additional reel whereupon the first reel becomes available for positioning upstream of the last one to continue the process.
