Method and apparatus for manufacturing structural, constitutive members, usable as bodies or modular strips

摘要

A modular strip, a method and an apparatus therefor, the method is carried out by additionally polymerizing by heat a partially polymerized sheet-like plastic laminate up to a temperature within 120° and 170°C, and shaping it into the desired shape during a period which is at most equal to the period during which the additional polymerization takes place, the resulting structural member being then cooled and definitely stabilized. The apparatus comprises a mounting frame (8) forming a conveying track (12) for the plastic laminate, said track including a heating chamber (2) ending in a mechanical molding zone on which a plurality of molding wall surfaces (6) are provided and are placed on each side of the center line of the track, said molding zone ending in a cooling zone for cooling the already molded strip. The modular strip having a tension-free flat central portion and opposite flanges defining together a C-shaped cross-section.
