Claims (2)

1. A method of producing tubing having alternating portions of longitudinally fluted walls and reduced outer diameter at the same time, as well as non-fluted walls and reduced outer diameter at the same time under advancing the tubing in longitudinal direction, whereby the tubing is subjected to intermittent diameter reduction and wall fluting operation or is only reduced in diameter under simultaneous impressing of shallo longitudinal grooves which extend only into a portion of the wall thickness.
2. Device for carrying out the method according to Claim 1 comprising a fluting die the opening of which corresponds to the outer diameter of the fluting, as well as a mandrel th surface of which corresponds to the inner diameter of the flutings characterized by a device for intermittent advancing the mandrel into the fluting die and for retracting the mandrel therefrom.
