The present invention has a cooling unit () as a temperature gradient formation unit for forming a temperature gradient in which the temperature is lowered in the direction from one surface () of a semi-cured prepreg sheet () layered on a top surface () of a layered body () toward the other surface () of a release sheet (), in a first region (C) of a layered sheet () located upstream from a first roller ().

Device for automatically layering prepreg sheets and method for layering prepreg sheets

This compactor includes first rollers having first roller surfaces that press a laminated sheet from the second surface side of a release sheet, the first rollers being disposed separated from each other; and a second roller having a second roller surface that presses the laminated sheet from the second surface side of the release sheet, the second roller being disposed such that the second roller surface faces a gap provided between the first rollers.
