So that insulating bars for composite profiles made from a thermoplastic plastics material may be manufactured economically with the respectively required dimensions and cross sectional shapes, in particular also having a corrugated structure of the base body, it is proposed that, in a first step, a strip-like extrudate having a substantially rectangular cross section should be produced from the plastics material and, in a subsequent step, an insulating bar arrangement having the shape of an individual insulating bar or the shape of a plurality of insulating bars that are joined together and are arranged parallel next to one another should be produced from the strip-like extrudate, and where appropriate the insulating bar arrangement should be severed in its longitudinal direction to give mutually separated insulating bars. |
