Abstract

The plate is pre-curved in its middle to form the apex (8) of the V-shape. Lateral squeezing pressure is applied to the two parts (5a,b) of the plate formed by the apex. The apex is rolled between a roller and a thrust piece or between two rollers. Near the apex is a hole (27) through both reflector walls and defined on both sides by apex pieces (8c). The adjacent edges of the reflector walls form the base of the hole.
