"Example" The details of this invention will be explained with reference to drawings.

FIG. 1 is a schematic diagram for explaining the production using a compression molding machine, and FIGS. 2 and 3 are diagrams for explaining the production using an injection molding machine. The mold 1 of the compression molding machine shown in FIG. Place the material 4 made of synthetic resin, heat the molds 1 and 2 with hot smoke such as gas, and melt the material 4 such as synthetic resin.
When a sheet-like object 5 such as cloth is placed and a hydraulic cylinder 7 is operated to clamp or pressurize it between the molds 1 and 2, a mesh in the shape of the mesh-like recesses 3 is formed on the surface of the sheet-like object 5 such as cloth. The shaped segments 6 are fused together. At this time, P/? Due to the adhesion force and pressure from the mold, and when it comes to cloth etc., the texture and w.
l. The molten resin etc. penetrates into the fiber structure, and the mesh segment 6 firmly attaches to the sheet-like object K1 and is cooled to become FfJ blue, pushing the sheet-like object. The mesh shape of the single mesh segment 6 may be of any shape or size, or may be a lattice shape with a large mesh. Alternatively, the mold 2 may be provided with a convex portion corresponding to the concave portion 3. When cooling the mesh segments 6, the composite made by attaching the mesh segments 6 to the surface of the sheet-like object 50 may be cooled as is without removing or removing the composite from the mold. The sets of 11 molds 1 and 2 sandwiched between the molds 1 and 2 were removed, and two water-cooled or air-cooled cooling plates 11 were installed below the heat source section 9 below the mold 1 with a heat insulating plate 10 in between. .11
If they are held in place, the heat of the heavy ring sheet-like object 5 and the mesh segments 6 will be absorbed by the cooling plates 11 and 11, and the solidification of the mesh segments 6 can be promoted.

The cooling plate 11.11 may be provided above the heat source above the mold 2 via a diagonal plate.

In the injection molding machine shown in FIG.
