And cooling medium discharge mechanisms 18, 18 are alternately arranged and supported. The heating medium discharge mechanisms 17 and 17 are configured to discharge a medium for heating the sheet S toward the sheet S from a plurality of discharge holes (not shown) perforated at the bottom, and the cooling medium. The discharge mechanisms 18 are configured to discharge the medium for cooling the sheet S toward the sheet S from a plurality of discharge holes (not shown) drilled in the bottom. Examples of the heating medium include steam and hot air. Examples of the cooling medium include air, and the air may be cooled in advance. Furthermore, the heating medium discharge mechanisms 17 and 17 and the cooling medium discharge mechanisms 18 and 18 are made of pipes in this embodiment, and the heating medium discharge mechanisms 17 and 17 are connected to a metal pipe. Reference numeral 18 denotes a flexible hose.

  The operation of the device constructed as described above will be described. First, in a state where the urethane adhesive is applied to at least one of the cushion pad K and the skin material H, the sheet S in which the cushion material K is coated with the skin material H is positioned by a positioning means (not shown) and the receiving jig 2 Placed on. Next, both ends of the shaft member 6 in the pressing jig J are hooked on the notches 10 a and 10 a of the bearings 10 and 10.

Then, the positioning means 11 and 11 determine the positions of the partial pressing members 3 and 3 and the groove pressing member 5 with respect to the sheet S. Specifically, the positioning is performed by passing the positioning pins 12 and 12 through the positioning holes 8a and 8a drilled in the clamped members 8 and 8 while holding the handle 7a in the pressing jig J. At this time, a slight displacement in the horizontal direction of the shaft member 6 due to the positioning is absorbed by a slight horizontal movement in the notches 10a and 10a of the bearings 10 and 10.

Then, the skin material H is pushed into the groove portion Ka formed in the cushion pad K by the groove pressing member 5 by pressing the handle 7a downward until the lower surfaces of the clamped members 8, 8 abut against the upper surfaces of the spacers 15, 15. The both ends of the concave surface portion Sb of the sheet S are pressed by the partial pressing members 3 and 3. Then, by closing the pressing clamps 14, 14, the pressing state of the groove pressing member 5 and the partial pressing members 3, 3 is maintained by the pressing clamps 14, 14.

Next, the support body 16 is lowered by the lifting means (not shown), and the heating medium discharging mechanisms 17 and 17 and the cooling medium discharging mechanisms 18 and 18 are brought close to the sheet S to desired positions. Then, steam as a heating medium is discharged toward the sheet S for 20 to 30 seconds from the plurality of discharge holes of the heating medium discharge mechanisms 17 and 17, and the sheet S is heated. As a result, the urethane adhesive is reacted and reactivated.

Then, after the discharge of the steam is stopped, air as a cooling medium is discharged from the plurality of discharge holes of the cooling medium discharge mechanisms 18 and 18 toward the sheet S for 20 to 30 seconds, and the sheet S is cooled. To do. As a result, the urethane adhesive is cured and the cushion pad K and the skin material H are bonded. Next, the support 16 is lifted by the lifting means (not shown), and the heating medium discharge mechanisms 17 and 17 and the cooling medium discharge mechanisms 18 and 18 are separated from the sheet S to desired positions. And the press clamps 14 and 14 are opened, the positioning of the positioning means 11 and 11 is cancelled | released, the hook to the said notches 10a and 10a of the shaft member 6 is removed, and the said press jig | tool J is integrally removed from an apparatus. Thereafter, the sheet S on the receiving jig 2 is taken out.

  In the present invention, by pressing the concave surface portion Sb of the sheet S with the partial pressing members 3 and 3, not only the concave surface portion Sb but also the convex surface portions Sa and Sa, the cushion pad K and the skin material H Both can be brought into close contact by tension. In this method, since the pressing area of the sheet S is small, it is possible to minimize the raising fall of the skin material H, and the sheet S has a large area exposed to the heating medium and the cooling medium. it can. Furthermore, a complicated shape pressing die or the like is not required.

In the present invention, since the heating medium discharge mechanisms 17 and 17 and the cooling medium discharge mechanisms 18 and 18 are supported by the same support body 16, the sheet S can be heated and cooled in a short time.

  Furthermore, in the present invention, as described above, the height dimension T (see FIG. 4) from the pressing surfaces 3a and 3a of the partial pressing members 3 and 3 to the pressing surface 5a of the protruding groove pressing member 5 can be adjusted. By adjusting the height dimension T, a linear design groove having a good appearance can be reliably formed on the surface of the sheet S.
