ABSTRACT:
The process of our invention heats a plurality of partially finished products extruded in an extrusion unit or changed in a transforming unit as a preparation for introduction into subsequent transformation or processing units. In extruding and/or transforming or heating the heat applied to at least one partially finished product length group is transferred during intermediate transport of the partially finished product length group and/or during storage by heat transfer with other partially finished product length groups. The heat transfer is caused by radiation, convention and/or direct contact. An apparatus for performing the process according to our invention comprising a thermal insulating chamber provided with an air flow and air feed devices and if necessary an auxiliary heating unit is also provided.
