PURPOSE:To form patterns on a wide variety of base materials by a method in which a supersonic vibration is applied to a base cloth and a thermoplastic base material for scooping out and hot bonding of the base material without causing damage to the cloth by spark. CONSTITUTION:A hot bonding mold 20 is lifted up, and under the condition, a synthetic fiber cloth 36 and a thermoplastic resin sheet base material 38 having a higher melting point than the cloth 36 are placed in a lapped state on a table 13. The hot bonding mold 20 is lowered, a mold 30 is pressed on the thermoplastic resin sheet base material 38 on a horn 12, and the tool horn 12 is supersonically vibrated. The cloth 36 and the base material 38 are supersonically vibrated in the pressed state by the presser 34 of the mold 30 and the base material 38 of lower melting point is melted. The base material 38 is hot-bonded to the cloth 36 by the presser 34 as the mold 30 goes down, and at the same time the melted portion is cut off by a cutter 32. At the same time as the cutter 32 reaches the cloth 36, a contactor 19 comes into contact with the tip of a stoper bolt 28, whereupon the lowering of the hot bonding mold 20 of stopped because of the action of the contact as electric contact. |
