Abstract
A heat chamfering method for a glass panel includes bringing a heater into contact with an edge of a glass panel by causing the heater to approach a chamfering start point, heat-chamfering the edge by moving the heater from the chamfering start point to a chamfering end point along a chamfering line, and bringing the heater into non-contact with the glass panel by causing the heater to depart from the chamfering end point. The heat-chamfering may include maintaining contact pressure between the heater moving along the chamfering line and the glass panel within a predetermined range of change. In the approaching, an angle defined by a chamfering start point approach line and the chamfering line at the chamfering start point ranges from 155° to 175°. In the departure, an angle defined by the chamfering line and a chamfering end point departure line ranges from 155° to 175°.
