2. Description of the Related Art Conventionally, a gasket is fitted into a gasket fitting groove of a heat exchange plate by holding a simple tool such as a rotating spatula in one hand and using it well, and by using the other hand. It was done manually by pushing it in. The above-mentioned manual work is difficult for even a seasoned worker because the fitting groove of the gasket is dovetail-shaped, and since it has strength on it, it is avoided by the worker. However, there was a problem that the number of operations performed was not large. In order to solve such a problem, the present inventor has devised the above gasket automatic fitting machine (which will be described later in detail as an embodiment). In realizing the above automatic gasket fitting machine, if, for example, only the fitting portion of the straight portion of the gasket is manually performed, it is needless to say that half of the above problems cannot be solved.
