題があった。In the sheet-form molding material made of the above-mentioned system, the compound between the carrier films is very flexible, so there is a risk that it will protrude from both ends of the upper and lower carrier films in the width direction immediately after the impregnation device. Furthermore, when the tension changes in the accumulate, there is a risk that the flexible compound will move within the carrier film and leak from both ends. Furthermore, when tension is applied during the winding process and the carrier film is wound into a roll, it tends to protrude from both ends of the carrier film, making it difficult to maintain the compound at a uniform thickness in the width direction and at a constant product width until the winding process. As a result, there is a problem in that winding misalignment occurs and further winding becomes impossible.
