Title: DEVICE FOR FEEDING YARN OR YARNS FOR KNITTING MACHINES FOR HOSIERY OR THE LIKE
Abstract:
A device for feeding yarn or yarns for knitting machines for hosiery or the like, comprising a supporting structure (2) which supports at least one yarn finger (3) having an elongated shape and being pivoted, at an intermediate portion thereof, to the supporting structure (2) about a corresponding rotation axis (4) and having, proximate to a longitudinal end thereof, a passage (5) for the yarn or yarns to be fed to the needles of the knitting forming machine, the device for feeding yarn or yarns comprising an electromagnetically actuated device (7) which acts on command on the at least one yarn finger (3) for its rotation, with respect to the supporting structure (2), about the corresponding rotation axis (4), from an inactive position to at least one active position, which is angularly spaced with respect to the inactive position about the rotation axis (4), or vice versa, the electromagnetically actuated device comprising at least one magnet (8) which is fixed to the at least one yarn finger (3) and at least one electric coil (9a, 9b) which is laterally adjacent to the at least one yarn finger (3) and is connected to the supporting structure (2). The at least one electric coil (9a, 9b) is able to be supplied electrically to generate a magnetic field that interacts with the at least one magnet (8) to actuate the rotation of the at least one yarn finger (3) about the corresponding rotation axis (4) with respect to the supporting structure (2).
