The machine comprises: a space defined between the needle cylinder and cylinder holder, and in communication with the delivery conduit of a feed pump, delivery ports defined on the needle cylinder for connecting the space to the outside, a collector pan located in the proximity of the needle cylinder base and supplying an oil collecting case in communication with the feed conduit of the cited pump. The delivery conduit is in communication with the cited space through the needle cylinder bearing and the oil collecting case houses the gear train for transmitting the rotary motion to the needle cylinder. The delivery ports are provided on the bottom of the needle cylinder flutes which accommodate the needles and jacks. Thus, thorough and continuous lubrication of the machine main members is achieved.
