发明名称 Method for the production of a tubular intermediate-product from spring steel material
摘要 Process used for manufacturing a sleeve-like intermediate product (22-1, 22-2) from knitted spring steel comprises cutting a tube (12) of knitted spring steel laid flat to form a two-layered knitted strip (16) perpendicular to the longitudinal direction of the tube and molding the resulting two-layered knitted component (20) into the sleeve-like intermediate product. The knitted component is bent to form the sleeve-shape so that the cut edges or the fold lines of the knitted component lie directly adjacent to each other and can be joined together. Preferred Features: The cut edges or the fold lines are joined together on the application of radial force.
