Abstract

PURPOSE: To enable molding without producing shrinkage and cracks at the inside, by a method wherein, after a temporary bending process is performed by means of a pressing device in a state such that a buffer material is placed on the channel inside and an outside surface of a channel type synthetic resin bar material, the resulting work is matched with a desired channel mold for heat-pressurizing.
CONSTITUTION: When a channel type bar material 1, whose metal foil A is covered with a clear or a semiclear synthetic resin P, is bent into a given angel, a gummous baffer material 2 is placed on the inside and outside surfaces 12 and 13 of a channel 11 of the bar material 1, and with this a temporary bending process is conducted at a pressing surface 31, formed in an arc of a circle, of a pressing device 3. The temporarily bent bar material 1 matched with a channel mold 4 having a desired curve is pressurized at a softening temperature of the synthetic resin, and afterwards, the bar is cured by cooling.
