っていた。2. Description of the Related Art Heretofore, it has been relied on press working to apply two types of composite material of a case for cooling and keeping heat of this kind on two sheets and apply a perforation (cutting in a perforated shape) to the shape of the case. In this case, the pressure of the press had to be increased because of the irregularities of the cuts. However,
When the press pressure becomes excessive, the cutting depth becomes uneven,
As a result, not only the case could not be cut evenly because the case came off from the composite material during cutting, but also many cases could not be molded at the same time, which was a major obstacle to mass production.

It is an object of the present invention to make it possible to perform simultaneous molding of a large number of cases by performing the cuts in separate steps and making equal cuts in a large number of cases by a mashing (perforated cut) in a third step.

時成型するように構成する。Means for Solving the Problems Two strips of a band-shaped composite material having a cooling and heat retaining property are intermittently introduced into a molding machine from a winding drum with their upper and lower sides back to back, and a product is produced in a first step. A welding process of a heat welding wire forming both side edges of the case is performed by a heat welding mechanism, and a heat welding process of forming a semicircular bottom plate of each of the multiple cases in a circular shape is also performed by the heat welding mechanism of the second step. By the cutting mechanism of the third step, a multi-cut (perforated) cut is made on the heat-welded wire which is also heat-welded in the previous step of many cases.
When the composite material is pulled out of the third step by the signal of the end of the operation of the cutting mechanism, the case group is separated from the composite material by a cutter using a hot wire to complete one process, and the signal of the composite material of the next process is obtained by the signal. The process of drawing into the molding machine is intermittently repeated, and a large number of cases are simultaneously molded for each process.

In accordance with the signal of the end of welding, heat welding is performed to make the semicircular bottom plate of each case circular by the heat welding in the second step, and the composite material is moved by the signal of the end of welding. The two side edges and the bottom plate group are moved to the third step and stopped, and according to the stop signal, each case is placed on the respective center lines of the heat welding lines by the heat welding in the previous two steps by the cut processing in the third step. A cut is made by cutting (perforation), the composite material is pulled out of the third step by a signal of the cut end, the case group is cut off by a cutter using a hot wire, and one step is completed. Then, the composite material is formed as described above. The process of intermittently and automatically introducing the case is repeated to mass-produce the case.
