Abstract
A workpiece heating and feeding device having a lid which is installed above a heating block which heats the workpieces, the lid having an opening formed in the central portion thereof wherein a transparent heat-resistant plate covers the opening in the lid. The lid may alternately be entirely made of a heat-resistant material. Since the heating block is covered, no dirt or dust can enter the interior of the device. In addition, since the lid has either a transparent plate or is itself made of a transparent heat-resistant material, working conditions can easily be monitored and adjustments to the feeding of the workpiece facilitated.
