Abstract:
The screw is intended for the extrusion or mixing of elastomers or plastic products. It comprises: a support, at least one sleeve having at least one relief projecting from an external face of the sleeve, and at least one split annular securing member, the member being clamped between the sleeve and the support in a radial direction with respect to an axis of the screw so as to secure the sleeve rigidly to the support. The member and the sleeve have frustoconical faces in mutual contact.
