Plural units are arranged on a carrier such as a bar conveyor.
As shown in FIG. 1 (3), the carrier is continuously driven from right to left in the drawing by driving the sprocket 4.

A plurality of linear lateral members (6) are made to intersect each other at intervals.
It is also possible to first dispose the linear lateral members on the carrier and then cross-dispose the linear longitudinal members on the linear lateral members.

The method of arranging on top is preferable. At this time, by arranging the lateral members while hooking the lateral members on the guide pins 8 provided at both ends of the carrier in the width direction, tension can be applied to the lateral members, and the lateral members do not bend between the longitudinal members.

る。By repeating such crossing arrangement of the vertical and horizontal members, it is possible to obtain a lattice-shaped body in which the crossing portions of the vertical and horizontal members are laminated in three or more layers. That is, the horizontal member is placed on the carrier by the first horizontal member feeder shown in FIG. 1 (7), the first vertical member shown in FIG. 1 (2) is placed on the carrier, and uncured on the first vertical member. 2nd by the lateral member feeder 9 via the resin impregnation tank 5
By arranging the horizontal members and arranging the second vertical member 10 on the horizontal members, it is possible to obtain a lattice having four layers of intersections.

合せる等の方法が好ましい。In the FRP grid-like body, it is important to secure the shear strength at the intersection of the vertical and horizontal members. For that purpose, it is necessary to crimp the intersection. When the uncured resin is cured by ultraviolet rays as shown in Fig. 1 (11), the linear vertical member (2) or ( Tensile force is applied to 10) and the intersection can be crimped by using this tension. The radius of curvature of the curve varies depending on the size of the lattice-shaped body and its usage, but is preferably about 10 to 40 m. or,
In the case of heat curing, a belt conveyor made of steel or synthetic resin for pressure-bonding the lattice-shaped body may be provided above the carrier near the curing furnace. In the case of ultraviolet curing, it is necessary to transmit light, and since such a pressure bonding belt conveyor cannot be used, the method of bending and utilizing tension as described above is effective. In order to bend, the rails provided at the lower ends of both ends of the carrier in the width direction so that the molded product can move with the same curvature in the moving shape from before the curing furnace of the molding carrier until it moves to the ear cutting machine. A method of matching the shape of the above with its curvature is preferable.

そ２〜3mm以上あればよい。The linear lateral member hooked to the guide pin in FIGS. 1 and 2 (8) is applied with a certain amount of tension, but this tension repels the above-mentioned pressure applied to the intersection due to the tension of the vertical member. However, the crimping may not be performed sufficiently. In order to solve this, it is effective to incline the guide pin outward in the width direction of the carrier or use a tapered guide pin. When the lateral member is crimped by the vertical member, the lateral member descends along the inclination of the guide pin and the tension of the lateral member is reduced, so that the lateral member can be sufficiently crimped. The distance between the guide pins of the horizontal member intersecting the vertical member decreases as the horizontal member descends along the inclination of the guide pin, but the amount of decrease may be approximately 2 to 3 mm or more.

よる方法に比べ約10倍の生産性にあたるものである。[Example] The resin-impregnated glass roving, which came out of the uncured vinyl ester resin impregnation tank shown in Figs. 1 and 2 (1) and (5), was vertically drawn out along the carrier advancing direction, and the vertical member Was placed at right angles to the vertical member while being hooked on the left and right pins 8 by the horizontal member feeders 7 and 9. The cross member was crossed in the order of horizontal member-vertical member, the uppermost part was a vertical member, and the crossing part was a lattice-shaped body having four layers. UV curing was performed in a curing furnace, the end of the lattice was cut with an ear cutting machine, and the cross-section was cut into a length of 3 m and taken out. The width of the obtained grid-like body was 2 m, the width of the vertical member and the width member was about 10 mm, and the size of the grid was 150 mm × 150 mm, and about 30 sheets could be taken out per hour. This is about 10 times more productive than the conventional manual method.
