The blow pin 31 is located in a draw-off device 6 movable from a position in contact with the nozzle 2 where it co-operates with the mandrel 29, to the position shown, where it co-operates with the movable blow mould members 11 to define the mould cavity. Projections 25 on the members 11 which have cutting edges 28 define with the extrusion nozzle 8 a cavity which accommodates the waste material.
