き出した状態になるように形成されている。As shown in FIG. 1, the skin material 2 that is press-bonded and pasted onto the molded base material 1 corresponds approximately to the size of the molded base material 1, and is attached to the back side of the molded base material 1 at the edge. A product is prepared that is cut and formed in advance outside the production line to a size that has a folding margin 2a for folding back. When this skin material 2 is placed from above the forming base material 1 as shown in FIG. 1(a), the folding margin 2a extends outward from the edge of the forming base material 1 as shown in FIG. 1(b). It is formed so that it sticks out.

れている。Further, to further explain the apparatus, the lower mold 4 is fixed to a bed 5 of the apparatus main body. On the other hand, the upper mold 3 is arranged to be movable up and down under the guidance of a guide means 6, and the vertical movement of this mold 3 is controlled by a hydraulic means 7. Furthermore, the mold 3 includes a molding base material 1
A plurality of knock bottles 8 are provided in a scattered manner at a portion corresponding to the folding margin 2a when the skin material 2 is correctly set. Each knock bottle 8 is protruded from a small chamber 3a formed in the mold 3 through a through hole 3b so as to be able to advance and retreat downward, and is attached to a coil spring 9 in the small chamber 3a. It is always pushed downward by force.

である。In the apparatus configured as described above, when press bonding the skin material 2 to the molded base material 1 that has already been molded, first, as shown in FIG. 2(a), the molded base material 1 is Set on mold 4. Note that before this setting, an adhesive such as hot melt is applied or arranged in a film form on the upper surface of the molded substrate 1, but this may be done after setting.
次いで、この成形基材１の上から表皮材２がかぶせられ

突き出しな状態にする。第２図（ａ）はこの状態で示し
ている。Next, a skin material 2 is placed over the molded base material 1. In this case, the folding margin 2a does not protrude to the outside of the molded base material 1. FIG. 2(a) shows this state.
次に、油圧装置７の制御により上側の金型３が下降され

０が完成する。In addition, in the process of transitioning from the state shown in FIG. 2(a) to the state shown in FIG. 2(b), each knock bottle 8 first comes into contact with the folding margin 2a, and this folding margin 2a
is brought into contact with the mold 4. As a result, the skin material 2 is strongly stretched on the molding base material 1 to smooth out wrinkles, etc.Next, the molding surface 3c of the mold 3 comes into contact with this strongly stretched skin material 2 and continues to descend. . At this time, the knock pin 8 holding the folding margin 2a is weakly abutting against the folding margin 2a due to the biasing force of the coil spring 9, and is not in contact with a very strong force, so it is only by the amount pulled by the mold 3. Allowing it to slip, it will eventually reach the state shown in FIG. 2(b). As a result, press adhesion is performed on the front side of the molded base material 1 and the skin material 2.Next, take it out from this device, turn the folding margin 2a to the back side of the molded base material 1, and paste it with adhesive. Molded ceiling 1 shown in Figure 3
0 is completed.
したがって、このようにして成形天井】０を製造する方
法では、成形基材１に重ね合わせ接合される表皮材２は
、予め成形基材１の一面の大きさにほぼ対応して形成さ
れて、製造ライン上で切削される不要部分を持たないの
で、製造ライン上での不要部分の切断作業がなくなる。Therefore, in the method of manufacturing the molded ceiling [0] in this way, the skin material 2 to be overlaid and bonded to the molded base material 1 is formed in advance to approximately correspond to the size of one side of the molded base material 1, Since there are no unnecessary parts to be cut on the production line, there is no need to cut unnecessary parts on the production line.
また、基材の大きさは最小限の大きさにして取り扱われ
るので作業がし易くなる。さらに製造ライン上での廃材
処理が不要になる。これにより作業性が向上する。Further, since the size of the base material is minimized, the work becomes easier. Furthermore, there is no need to dispose of waste materials on the production line. This improves work efficiency.
なお、上記実施例では、本発明による製造方法を適用す
