PROTECTING SHEET AND LAMINATED FIBER MANUFACTURING METHOD

摘要

PURPOSE: To obtain a protective sheet to be rigidly positioned by forming a ferromagnetic protective sheet. CONSTITUTION: A thermoplastic resin sheet 1a is covered on both surfaces with protective sheets 2, 3. The sheet 2 is formed of a flexible base layer 4 adhered to the sheet 1a and a ferromagnetic layer 5 bonded to the layer 4. Meanwhile, the sheet 3 provided at the other side of the resin sheet is formed of a base layer/ferromagnetic layer integrated by intruding ferromagnetic element like a woven fabric. As an economical application, it is desirable to provide protective sheets of the same type on both the surfaces. Thus, the protective sheet and a thermosetting resin sheet can be effectively fixed without requiring a relatively accurate fixing unit or a vacuum unit.
