Abstract
A feeding unit to feed a component in an automatic manufacturing machine; has: at least one holding head designed to receive and hold the component; a closed curved guide arranged in a fixed position along an application path; an equipment supporting the holding head and provided with at least one slide coupled to the guide by a plurality of wheels; a linear electric motor, and a movable slider electro-magnetically coupled to the stator and is rigidly connected to the slide. The guide has, on the surface in contact with the wheels, a first transverse profile having a concavity or a convexity; the wheels have, on the surface in contact with the guide, a second transverse profile, which has a convexity or a concavity, and generates, with the first profile, a shape coupling between the guide and the wheels, which forbids a transverse movement of the slide relative to the guide.
