ABSTRACT:
A method for manufacturing perforated plastic pipes, in particular corrugated thermoplastic pipes of which the wave valleys are perforated by at least one punching member, to which a velocity is imparted in the direction of conveyance of the plastic pipes, which equals the rate of conveyance of these pipes. During the punching operation the punching member or members retain substantially a perpendicular position with respect to the plastic pipes.
