Abstract: A reinforced plastic pipe is produced by feeding a plastic tube along a feed path while directing a reinforcement strip into a path around a tube so as to wind it into spiral coils which are spaced radially outwardly of the tube and including subsequently pushing the coils in an axial direction while deflecting them inwardly to cause their diameters to be reduced so that they engage around the surface of the tube. The tube is advantageously fed directly from an extruder in a tacky state so that the reinforcement strip will be immediately bound to the surface when it is directed into engagement therewith. The apparatus for carrying out the method includes a thin tubular mandrel disposed around the tube which is formed by an extruder and a winding device is associated with a reel supply of the reinforcement strip so as to feed it around the mandrel.
