<p>A circular knitting machine (1 ) for knitwear or hosiery, comprising a bearing structure, at least a needle-bearing organ or needle cylinder rotatably mounted in the bearing structure; a plurality of needles supported by the needle cylinder and mobile parallel to a rotation axis of the needle cylinder for producing a knitted fabric; a dial group (3) arranged above the needle cylinder. The dial group (3) comprises a support ring (4) solidly constrained to the bearing structure and coaxial to the needle cylinder, a thread transport and cutting group, or "cutter" (4a) rotatably mounted externally of the support ring (4) and a plurality of pneumatic activating devices (5) arranged on the support ring (4), each comprising one or more respective pneumatic actuators and one or more respective solenoid valves configured and predisposed to activate or deactivate the pneumatic supply of the pneumatic actuators. The dial group (3) comprises at least a first pathway of pneumatic supply (6) provided with a single main inlet (7) for pneumatic supply, positioned in the dial group and destined to be connected to a compressed air source of the knitting machine; the first pneumatic supply pathway (6) being configured for pneumatically supplying the pneumatic actuators of at least a first group of devices of the plurality of pneumatically activating device (5) present in the dial group (3).</p> |
