Abstract
A mobile cam device (1) for commanding needles of a needle bed of a knitting machine, the device (1) comprising: at least a body (2) having at least an air inlet (3) destined to be connected to a source of compressed air, at least a first housing seating (4a) for movably housing at least a first actuator (5a) in the body (2), and having at least a first air pathway (6a) defined internally of the body (2) and connecting the at least an air inlet (3) with the first seating (4a) for moving the actuator by means of the compressed air, the device further comprises at least a first command cam (8a) movably mounted and associated to the body (2) and destined to interact with at least a needle of a needle bed of a knitting machine, and at least a first actuator (5a), movably housed at least partially in the first housing seating (4a) in the body (2) and destined to move in a controlled way the first command cam (8a). The device further comprises at least a first solenoid valve (9a) mounted and connected directly to the body (2) of the device and active directly at least on the first air pathway (6a), the first solenoid valve being configured and predisposed to selectively enable or prevent passage of air in the first air pathway (6a) such as to selectively activate the first actuator.
