Feed roller

Image Number 2 for United States Patent #4889271.

A feed roller having a hard roller body and a cylindrical resilient cover member fitted onto the hard roller body. The feed roller has internal contact portions formed on an inner surface of the cover member, the internal contact portions being kept in contact with the outer periphery of the roller body when the cover member is fitted onto the roller body; external contact portions formed on an outer surface of the cover member so as to project outwardly in the radial direction of the cover member; and spaces defined between the inner surfaces of the external contact portions and the outer periphery of the roller body. Accordingly, the cover member can easily be attached to the roller body and enables objects to be fed by a small clamping reaction force, thereby preventing the objects from being damaged.
