Abstract:
A process for producing a metallic track member comprising:a) providing stud locking slots at selected locations in a relatively flat sheet of metallic material, the sheet of metallic material having a longitudinal axis and a first longitudinal edge, b) marking the sheet of metallic material at repetitive locations to provide indicants thereon, c) bending the sheet of metallic material containing the indicants to form a W-shaped track in accordance with the steps of: (i) forming first and second substantially identical and parallel vertical wall sections forming opposing vertical walls of the track; (ii) forming first and second substantially identical horizontal base sections having a first width and projecting at about 90Â° from corresponding adjacent wall sections at one extremity and along the entire length thereof; (iii) forming first and second substantially identical vertical intermediate sections projecting from an extremity of adjacent base sections opposite to the respective wall sections and having transverse cross-sections in the shape of the sides and tops of truncated isosoceles triangles, each intermediate section having at least one locking slot adapted for receiving and retaining portions of a metallic stud member; and (iv) forming a third horizontal base section having a second width between the vertical intermediate sections, and d) severing the W-shaped track at a predetermined length.
