Method of making a window panel with a synthetic resin frame.

摘要

A method of making a window panel (1) with a synthetic resin frame comprising forming a synthetic resin frame by extruding synthetic resin through a die (3) into a specified shape along a peripheral portion of a plate-like material for a window on at least one surface of the plate-like material, and curing the formed synthetic resin frame so that the synthetic resin frame is formed integrally with the peripheral portion of the plate-like material, characterized in that the die is moved to trace a locus along a peripheral portion of the plate-like material which has been previously inputted, and the locus and the angular position of the die are corrected by detecting a position of the end face of the plate-like material, whereby the synthetic resin frame having a specified shape is formed.
