Abstract:
A method for the arc-like shaping of a profiled strand of a thermoplastic material, said method comprising the steps of: heating at least a section of the profiled strand and of a support ledge disposed in spaced relationship from the area of the profiled strand from which the arc is to be formed in an air-circulation hot air heating chamber to a predetermined temperature facilitating the shaping, after reaching said predetermined temperature, firmly engaging said support ledge with said profiled strand at an inside arc area which is the compression side, engaging a support profile heated to a lesser degree than said support ledge with the outer side of the profile strand section to be bent to provide a packaged profiled strand, bending the packaged profiled strand of thermoplastic material, together with said support ledge and said support profile, around a template structure, plane-pressing said bent profile strand, and, after a cool-down period, separating said support ledges and support profiles from said profiled strand.
