A predetermined amount of the expandable synthetic resin material 6 is injected into the back surface 1a side of the material 1 by the expandable synthetic resin material discharge device 5 (second means). The foamable synthetic resin material 6 is generally made of a hard resin such as polyurethane, polyisocyanurate, polyimide, phenol, or epoxy, but may be semi-hard or soft.

Further, to the siding surface material 1 in which the expandable synthetic resin material 6 is injected, a sheet-like back surface material 8 having a required width which is continuously sent out from above the siding surface material 1 by a sending device 7, The non-finished product 9 of a continuous body is formed as shown in FIG. 10 by adhering appropriately in a continuous manner in the longitudinal direction (third means). As a means for fixing the sheet-shaped back surface material 8 to both ends 1b, 1c of the siding surface material 1, both may be fixed by an adhesive, or the end portion of the siding surface material 1 may be the end portion of the sheet back surface material 8. You may fold it inside and stick both together. Further, both may be fixed by the self-adhesiveness of the injected foamable synthetic resin material 6. As the sheet-shaped backing material 8, for example, aluminum foil paper, kraft paper, polyethylene-processed kraft paper, asphalt paper or the like is used.

Next, a non-finished product 9 of a continuous body as shown in FIG. 10 in which the sheet-shaped back surface material 8 is fixed to the siding surface material 1 into which the expandable synthetic resin material 6 is injected,
An appropriate required temperature (for example, approximately 6
It is continuously fed at a line speed of about 31 to 47 m / sec between the roller 11 and the flat belt 12 in the foam hardening and conveying device 10 at 0 ° C.
