Abstract
A dot matrix print head of improved type is described the principal characteristic of which lies in the fact that the casing containing the electromagnets actuating the needles is clamped between the needle support body and a cover carrying on its interior the striker elements which, when attracted by the electromagnets, displace the needles; the casing is formed by an extruded metal tube body and by an element of plastics material between which are inserted, in appropriate grooves, stacks of U-shape laminations carrying at one end respective electrical windings constituting the electromagnets.
