Abstract

PURPOSE: To easily make the unevenness of a flexible tube by inputting a core rod inside a metal tube, drawing the external wall of a metal tube by upper and lower dies and folding the die in the longitudinal direction of the metal tube.
CONSTITUTION: A core rod 2 is inputted into a metal tube 1, the external wall of the metal tube is drawn smaller than the outer diameter of the metal tube at several and scores places by an upper die 3 and lower die 4 and after providing a recessed part on the external wall of the metal tube, the dies 3, 4 are folded in the longitudinal direction of the metal tube 1. The unevenness of a flexible tube can thus be easily formed on any part of a long metal tube.
