Abstract
A novel die member for positioning in a uniformly tapering, frustoconical portion of a through bore in a body member of co-extrusion, cross-head coating apparatus. The die member has an external surface with a first, frustoconical portion dimensioned for mating engagement with the body member bore extending from the front end of the die member and tapering outwardly to terminate in a plane parallel to and intermediate of the planes of the front and rear ends of the member. A second, cylindrical, external surface portion, of smaller diameter than the adjacent, larger end of the first surface portion, extends to the rear end of the die member. An annular groove of substantially semi-circular cross section extends into and 360.degree. about the second surface portion rearwardly adjacent the first surface portion.
