ABSTRACT:
The thread feed unit has a supporting block which can be associated with a knitting machine laterally to the needle cylinder or cylinders and is provided with at least one thread guide which has a body provided with an elongated configuration associated with a supporting element and slidable along a direction substantially parallel to its longitudinal extension. The supporting element is associated with the supporting block for oscillation about an oscillation axis transverse to the sliding direction of the thread guide body. A first thread guide actuator is provided and controllably acts on the supporting element to oscillate the thread guide about the oscillation axis, and a second actuator controlling the thread guide body to slide it longitudinally with respect to the supporting element. The first actuator and the second actuator are associated with the supporting block and can be actuated independently of one another.
