Abstract (en)
The invention refers to the manufacturing procedure for a convoluted tube (26) using a tube (28) which has previously been fitted with recesses (18) obtained by turning (14) and applying a tool (25) formed by a holder (10) equipped with discs (22) at regular distances, an inner surface (22a), operating in combination with a support (21) which is fitted inside the tube (14) to be then subjected to a compression force on the end from the head (27) of the support (21).
