Abstract

The synthetic, pref. elastomeric, resin is mixed with a curing agent (e.g. an org. peroxide) and fed by e.g. a screw feed to an extrusion head while being maintained at below the curing temp. and the resin is heated to the curing temp. just as it passes to the extrusion nozzle, the time period between then instant at which the material is extruded being at most equal to the period required to start the curing process. The method may be used for extruding sheaths onto high tension cables, and extrusion can take place at high speeds as subsequent curing process can be of reduced duration.
