Abstract
A device for feeding a yarn to a textile machine includes a housing with which a rotary member is associated to cooperate with the yarn unwinding from a package and directed, on leaving the device, to the machine where it is processed. Correct feed of the yarn is monitored by a feed controller associated with the housing in accordance with at least one measured parameter related to the rotary member or to an intrinsic characteristic of the yarn such as its tension or its feed velocity. A yarn cutting member is provided. This is connected to and controlled by the controller on the basis of the measured parameter of the yarn. The cutting member is activated by the controller to cut the yarn whenever the parameter monitored by the controller has a value exceeding a predetermined required value.
