While there have been disclosed in this specification several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of iliustration only. and that the invention is not to be limited ?to the specific disclosures but may be modified and embodied in various other forms without departing from its spirit. In short. the invention includes all the modifications and embodiments coming within the scope of the following claim.

Having thus fully described the invention what is claimed as new and for which it is desired to secure Letters Patent is:

In a. lnitting needle, a pair of relatively large metal knitting sections having .pointed outer ends, and a relatively small fiexible' metal central strand butt-welded to the inner ends of said knitting sections, the ends of said strand having enlarged tapered sections, and the inne! ends of said knitting sections being reduced to substantially the same diameter as said enlarged tapered sections at the welded joints. v
