Abstract

The method of making tubes provided with fins of fine pitch, which comprises the operations of causing the rotation of a smooth tube and a fin forming roller having a plurality of discs of progressively increasing diameter, cause a movement of relative advance between said tube and the roller in a substantially radial direction to said tube to depress the peripheral portions of the discs to a predetermined depth in the material of said tube, and decrease the angle of taper of the roller relative to said tube and increase the angle of the tube. obliquity of said roller relative to said tube during the forward movement.
