Abstract

PURPOSE: To provide the titled frame in a reduced number of production steps and without material loss by a method wherein plate-shaped synthetic resin blanks split into the shape of plate-shaped synthetic resin blanks split into the shape of comb teeth are subjected to heat and pressure applied from top and bottom forces for lengthening and mutually jointing the projected portions in the shape of comb teeth, and a flange portion is formed along the outside peripheral portion.
CONSTITUTION: A sheet frame blank 4 made of reinforced synthetic resin is equally split into the shape of comb teeth to become intermediate frame stocks 5a, 5b and cut at positions indicated by broken lines to a desired length. The thus cut intermediate frame stocks 5a, 5b are placed on a bottom force 8 at certain intervals, the projected portions being opposite to each other and the branch portions 3 being fitted to the holder metals 9 on the force 8. After heating the intermediate stocks 5a, 5b, a top force 6 is lowered so that presser metals 7 lengthen the projected portions 11 in the direction of arrows to mutually joint the projected portions 11 and simultaneously a flange 2 is formed along the periphery. Due to the presence of the holder metals 9, the lengthening or elongation is restricted to the projected portions 11 and in the direction of arrows, i.e. the projected portions 11 are not elongated sideways.
