Pneumatic service circuit for circular knitting machine service devices

摘要

The circular knitting machine has a pneumatic service circuit with pneumatically actuated service devices arranged around the needle cylinder. An annular body surrounds the needle cylinder, and a main duct is defined in the annular body. The main duct is supplied with pressurized air and is connected to the supply ducts of pneumatic actuators which actuate the service devices. Valve for operating the actuators are arranged between the actuator supply ducts and the main duct.
