（発明が解決しようとする問題点） 特開昭59-150740号公報に開示の技術にあっては、表皮
材にシワや破れのない良好な外観を備えた積層体を製造
することができるが、予め若しくは成形後に必ず表皮材
の切断行程ばかりでなく、表皮材の切断機を別途必要と
する上、成形装置と切断装置とが別体であるから表皮材
と合成樹脂の芯がずれるという問題点があった。(Problems to be Solved by the Invention) In the technique disclosed in Japanese Patent Laid-Open No. 59-150740, it is possible to produce a laminate having a good appearance without wrinkles or tears on the skin material. The problem that not only the process of cutting the skin material in advance or after molding, but also a separate machine for cutting the skin material is required and the core of the skin material and the synthetic resin are misaligned because the molding device and the cutting device are separate bodies. There was a point.

融樹脂を射出してこのキャビテイ内を展延させながら塑
性変形をしているために、熔融樹脂の射出時には表皮材
は保持されておらず、このために表皮材に歪み、シワ等
が形成する可能性がある。Further, in the technique disclosed in Japanese Patent Laid-Open No. 59-150740, after the skin material is cut and pushed into the cavity, the molten resin is injected to cause plastic deformation while spreading the inside of the cavity. Therefore, the skin material is not held at the time of injection of the molten resin, which may cause distortion, wrinkles or the like in the skin material.
切断された時の表皮材は雄型の差し渡し長さに相当する
長さの直線状となっているが、型締め状態においては雄
型の複雑形状のキャビティ面に沿った延べ長さとなるか
ら、形状によっては切断時の長さの数倍にも延伸される
こととなる。The skin material when cut is a straight line with a length corresponding to the crossover length of the male mold, but in the mold clamped state it becomes the total length along the cavity surface of the male complicated shape, Depending on the shape, it may be stretched to several times the length at the time of cutting.
しかるに、金型内の表皮材は既に切断され保持されない
状態にあるから、延伸のコントロールが十分にされず、
表皮材がキャビティ内を滑らなくなり、部分的な延伸状
態となったり、キャビティ末端まで完全に延伸しない欠
点がある。However, since the skin material in the mold is already cut and not held, the stretching control is not sufficient,
There are drawbacks that the skin material does not slip in the cavity, it is in a partially stretched state, or it does not stretch completely to the end of the cavity.
しかも、是ほどに延伸されるので、表皮材の厚みも最初
に供給したときの厚みを維持することができず、延伸の
程度によって表皮材の厚みにムラが生じる。Moreover, since the material is stretched to such an extent, the thickness of the skin material cannot be maintained as it was initially supplied, and the thickness of the skin material varies depending on the degree of stretching.
