Heating device for elongated workpieces

摘要

The apparatus (1) has heating elements (8-10) and fans (11,12) which are provided for generating circulating air flow through the heating channel (3). A workpiece channel (2) has segments (4-6) with respect to longitudinal portion of heating channel fixed with core segment (4) and extension segments (5,6) along heating channel optionally. The heating channel is extended over the entire length of workpiece channel and is divided in length of heating elements. The circulating air flow and/or ambient air flow through the heating channel is limited in accordance with heating elements.
