Moulded-in structural metal tapes have a significant effect on the
fastening function and bending behaviour of elastomeric profiles.
The important adhesion between extrudate and metal core depends on
prior treatment of the structural tape. The metal core heater
ensures that adhesion-reducing oils and impurities are rapidly
eliminated on the hot tape. The core temperature of the structural
tape is simultaneously raised to the required extrusion
temperature.
