STRIP TYPE ELECTRIC HEATING WIRE BENDING APPARATUS AND METHOD AND HEAT GENERATING MEMBER FORMED OF STRIP TYPE ELECTRIC HEATING WIRE

摘要

The present invention relates to a strip-type electric heating wire bending apparatus to bend a strip-type electric heating wire whose thickness is smaller than the width thereof and whose cross section is rectangular. The strip-type electric heating wire bending apparatus comprises: a flat base plate to support the strip-type electric heating wire while keeping a surface of the strip-type electric heating wire forming the width horizontal; a guide slot curved and formed on the flat base plate; a cylindrical bending roller mounted in the guide slot to rotate about an axial line and move on the base plate along the guide slot; a bending press unit disposed on a lower surface of the bending roller to apply a bending stress on a side surface of a target strip-type electric heating wire forming the thickness while rotating the bending roller about the axial line and moving the bending roller along the guide slot; and a bending support unit disposed to face the bending press unit in a radial direction of the bending press unit and separated from the bending press unit by the strip-type electric heating wire to support the strip-type electric heating wire to which the bending stress is applied from the bending press unit.
