Abstract: Apparatus for manufacturing poles of reinforced plastics material by advancing a prefabricated hollow core of plastics material coaxially with a plurality of resin impregnated reinforcing threads, the threads being held tight and radially distributed around the core and being caused to adhere thereto, spirally winding at least one impregnated reinforcing thread around to at least partially cover the core and impregnated reinforcing threads during their advance, and leaving the core and the impregnated reinforcing threads to harden to obtain the union of the threads with the core.
