<p>A first screw conveyor (10) advances synthetic resin material within a conveying channel (13), and a second screw conveyor (20) advances fluid synthetic resin under pressure and mixes it with reinforcing fibres within a respective conveying channel (23); for pressure-injecting the material into the user means there is provided a chamber (30) having a thrust piston (31) axially slidable within the chamber (30) to discharge the fluid material under pressure through said exit (32). A first conduit (41) connects the final end of the channel of the first conveyor (10) to an intermediate point of the channel of the second conveyor (20), to transfer the fluid material from the first channel (13) to the second channel (23), and a second conduit (42) connects the exit end of the second conveyor (20) to the injection chamber (30); means are provided for axially driving the thrust piston (31) to compress the injection chamber (30).</p> |
