Reference numeral H denotes a laminate forming device, and as shown in Fig. 2.3, this device is used to form a laminate on the front edge of the grooves 3 and 3' and the support plate 5.5 loosely fitted into the grooves 3 and 3'. It is comprised of taper IW11sI, 51' formed in a downward slope. During molding, the flat laminate that is guided by the rising parts 3m and 3m' over the bell) 1 and the support plate 5.5' is directed directly to the position where the tenoso parts 51 and 51' are formed. It is only necessary to advance the laminate so that its sides are aligned with the grooves 3.
While contacting the inner surface of 3', the concave groove 3 gradually forms due to its own weight.
, 3', and as shown in Figure 3.5, it bends slightly inward at point A as shown in the figure. This bend gradually becomes larger as it descends from the 8th section 151.51', and the 8th section 51.51'.
When it has finished descending, it is further bent outward through the bottom corners of the grooves 3, 3', and at point B, the whole is formed into an inverted trough shape as shown in the figure. During the above-mentioned forming, the laminate is finished by a finishing roller 52 disposed close to the root surface when the surface of the intermediate portion is located between the teeth 79 and 151. Finishing rollers ms and ss' are disposed within the side grooves 3 and 3' and close to the bottom surface of the groove, and the outer surfaces of both sides are further disposed close to the inner surface of the groove. Finishing roller 84.
54', the surface finishing is performed sequentially. This laminate is then introduced into the steam curing chamber I and cured.
The cured laminate is sent out onto the feed rollers 5 and 57' while separating from the belt 1, and is cut to a constant width by a longitudinal cutter 58 provided on the feed roller, and then cut to a constant length by a width direction cutter B9. A GRC plate of a fixed size can be obtained by cutting the belt 1 to a fixed size.
60, the deposits are removed, washed with washing water jetted from the water washing device r#61, and dried with dry air blown from the air blower 62.
