MACCHINA CIRCOLARE PER MAGLIERIA O CALZETTERIA CON CIRCUITO PNEUMATICO DI SERVIZIO PERFEZIONATO

摘要

The circular knitting machine with improved pneumatic service circuit comprises a needle cylinder (2) and pneumatically actuated service devices which are arranged around the needle cylinder (2). The machine is provided with an annular body (4) which surrounds the needle cylinder (2), and a main duct (5) is defined in the annular body (4). The main duct (5) is supplied with pressurized air and is connected to the supply ducts (14) of pneumatic actuators (11) which actuate the service devices (9). Valve elements (17) which can be driven to actuate the actuators (11) are arranged between the actuator supply ducts (14) and the main duct (5).
