In FIG. 1, 1 is a cushioning material, and 2 is an outer skin, both of which are shaped in advance into a predetermined shape. As shown in FIG. 1(I), the cushion material 1 is set in the upper mold 3, the skin 2 is set in the lower mold 5, and a hot melt adhesive in a molten state is applied with an adhesive coating gun 6. Apply to cushion material l. The adhesive is applied to the cushion material 1 using the upper mold 3.
The mold in which the cushion material 1 is set may be placed on the lower side, and the mold in which the skin 2 is set on the upper side.

とが好ましい。In any case, the mold in which the cushioning material 1 is set (
On the national side, a large number of nozzles 4 are installed in the upper mold 3). As shown in FIG. 2, this nozzle 4 is connected to a steam generator 9 (which may also be a hot air generator) via a pipe 11, and a control valve 12 is provided on the pipe 11. As shown in FIG. 4, the arrangement of the nozzle 4 is set to correspond to the position of a large number of through holes 1b that are pre-drilled in the groove portion 1a of the cushion material 1.The tip of this nozzle 4 is as shown in FIG. As shown in the figure, it is preferable to provide a large number of small holes 4a to disperse and blow out steam (or hot air).

) This compression is performed to such an extent that a slight gap 7 is formed between the facing surfaces of the cushion material 1 and the outer skin 2, as shown in FIG. 1 (II-1). At this time, nozzle 4
passes through the through hole 1b from the back side of the cushioning material 1 and faces the gap 7. In this state, the control valve 12 shown in FIG. 2 is opened, and as shown in FIG. 1 (II-2), steam ( or hot air) is injected into the gap 7. This gap 7
The temperature of the steam (or hot air) injected into the interior is approximately 60~8
The temperature is 0° C., and the injection time is about 20 to 30 seconds. This means that the melting temperature of hot melt adhesive is 100 to 1
Although the temperature is 30°C, as mentioned above, since the molten adhesive is applied to the cushioning material 1 immediately before or after setting the cushioning material 1 in the press mold, the drop in the temperature of the adhesive over time is compensated for. This is because the molten state can be sufficiently reproduced just by doing so.

The cushion material 1 and the skin 2 are bonded and integrated.

。<Effects of the Invention> As described above, according to the present invention, immediately before setting in the press mold,
Alternatively, a hot-melt adhesive in a molten state is applied to the cushioning material immediately after, compressed using a press mold to create a gap between the cushioning material and the facing skin, and steam or hot air is injected into this gap using a nozzle. Because of this, steam or hot air is applied directly to the adhesive, and the temperature of the adhesive, which has fallen over time, is brought to the melting temperature at an early stage, and the process of crimping the cushioning material and the skin can be started in a short time, making it possible to speed up the bonding process. Manufacturing efficiency can be improved by reducing time.

る。In addition, since the steam or hot air is injected into the gap between the cushioning material and the skin that form the wall, the steam or hot air spreads to every corner, melting the applied adhesive over the entire surface and melting it. As a result, the cushioning material and the skin are bonded and integrated during the crimping process.

る格別な効果を有している。Furthermore, since the steam or hot air injected into the gap passes through the cushion material from the back side of the cushion material and faces the gap, compared to the conventional method of penetrating the outer skin, the steam or hot air passes through the cushion material. This is an exceptional product that prevents deterioration of the epidermis, and can be applied to non-breathable leather, etc., rather than being limited to breathable epidermis, expanding the range of materials that can be used for the epidermis. It has a great effect.

れる。Additionally, in the crimping step, by switching from a steam or hot air nozzle to a cold air jet, the adhesive hardens more quickly, and the press-type crimping holding time can be shortened.
