Abstract

1. Conical tube (1) having a continuously reducing cross-section and consisting of helically wound strip material (2) provided with a helically running seam (4) the pitch of which is decreasing continuously axially of the tube (1) wherein in longitudinal direction of the seam the edges of the strip material are strongly connected to one another, characterized in that the strip material (2) is wound axially of the tube in direction (D) of the continuously increasing cross-section of the tube forming an acute angel (alpha) of pitch of the seam (4) which is continuously decreasing with respect to the perpendicular (C) to the longitudinal axis (A) of the tube.
