Abstract
A local heating source is provided in a heating furnace in which a glass plate is continuously conveyed. The heating source is position-controlled by numerical data in a direction along the glass surface in accordance with the conveyance of the glass plate, so as to data-control the heating trace. As a result, the heating patterns can be easily altered in units of article types of the glass plates which are to be bent in different shapes, resulting in highly efficient production on a multi article type-small lot base.
