Simultaneously, the base mold 60 is pressed during 40 to 80 seconds, as shown in Fig. 18. Therefore, the burr 3c formed at the edge of the air hole 3b of the polyurethane foam sheet 3 is flatted, as shown in Fig. 14. Referring to Fig. 15, while the polyurethane foam sheet engaged to the bottom of the artificial leather sheet lw is pressed, the burr 3c is compressed to be flat, thereby causing the bottom of the completed shoe upper 2b to be flatted.

The reason is because the third embodiment utilizes the pre-adhered artificial leather/polyurethane foam sheet and high heat does not apply to the artificial leather and polyurethane foam sheet.
  • the polyurethane foam sheet 30 adhered to the artificial leather 10 by an adhesive is laid on the blade 50b protruded from the middle mold 500. Then, the middle mold 500 is inserted into the base mold 600 of a hot press.
