Preferably, the temperature for heating the facing surface of the second facing material is not less than the melting point of the second facing material. Of course, this method is only applicable where the second facestock component includes chemical synthetic fibers, since the chemical synthetic fibers melt when heated to their melting point. The second facing material joining surface is heated to gel (melt) only a surface portion of the joining surface without affecting the entire strength thereof. Before the second surface fabric and the first surface fabric are pressed and attached, the attaching surface of the second surface fabric is heated, on one hand, the second surface fabric is preheated before being pressed and attached with the first surface fabric, when the outside air temperature is lower, the phenomenon that the partial temperature of glue on the first surface fabric is too low when the glue is contacted with the second surface fabric to influence the fluidity and the adhesive force of the glue is avoided, on the other hand, the problem of controlling a second heating device can enable the surface of the second surface fabric to be gelatinized at a certain temperature, and under the condition that the glue amount is not changed, the adhesion and the strength of the first surface fabric and the second surface fabric are further enhanced.
