1. to be formed, there is the longitudinal device changing the section bar of cross section for continuous progressive molding metal tape, comprising:

  • -for the equipment of formed strip (11),-wherein this equipment comprise at least one suite of tools (1,1'"'"', 1 ", 1 " '"'"'), at least one suite of tools described (1,1'"'"', 1 ", 1 " '"'"') there are at least two rotatable installations and the instrument that is mutually related (2A, 2B, 2C, 2D)-wherein instrument (2A, 2B, 2C, 2D) there is circumferential pressure face (4A, 4B, 4C, 4D) in a circumferential direction, this circumferential pressure face (4A, 4B, 4C, 4D) has the profile (5A, 5B, 5C, 5D) for formed strip (11), and-wherein the profile (5A, 5B, 5C, 5D) of the pressure face (4A, 4B, 4C, 4D) of at least one instrument (2A, 2B, 2C, 2D) be nonaxisymmetrical,It is characterized in that,At least one suite of tools (1,1'"'"', 1 ", 1 " '"'"') the profile (5A, 5B, 5C, 5D) of pressure face (4A, 4B, 4C, 4D) of all instruments (2A, 2B, 2C, 2D) be recessed, to form the section bar with closed cross-section.
