Abstract

PURPOSE:To carry out hemming operation in a simple process by a method wherein a thermoplastic sheet is laid on the surface of a core plate, the peripheral edge of the said sheet is hemmed about the back side of the core plate, welded and fused on the back side with an upper electrode of high frequency having a welding part outside and a cutter on the inner edge zone. CONSTITUTION:A thermoplastic resin sheet 6 is laid on the surface of a core plate with the back side of which a cloth 1 is bonded, and the peripheral edge of the sheet 6 is hemmed about the back side of the core plate 3. Then, the whole is turned over and placed on a lower electrode 7 of high frequency. High frequency voltage is applied to the said hemmed zone 8 with the upper electrode 11 having a welding part 9 on the outside and a cutter part on the inside edge. Therefore, the outside of the hemmed zone 8 is welded into the back side of the core plate 3 and the inside edge of this welded zone is fused and cut. In this way, backing plates, covers of hemmed edge-style vessels can be manufactured readily and this hemmed zone can be finished fine.
