    • It is an object of the invention to provide a method and an apparatus for producing a three-dimensional decoration piece which do not damage the tacky bonding or adhesion strength of the lower layer material of the decoration piece. The method comprises putting an upper layer material (11a, 12a) on a first table (31) operating as cathode; lowering an upper mold (21) operating as anode onto the first table (31) to press the upper layer material (11a), emitting a high frequency wave for induction heating, to form a three-dimensionally formed body (14b) from the upper layer material (11a) by molding and fusion-cutting and temporarily holding the three-dimensionally formed body (14b) to the upper mold; stopping the high frequency induction heating; moving a second table (41) carrying a lower layer material (13 a) having a tacky bonding property to below the upper mold (21) temporarily holding the three-dimensionally formed body (14b); and lowering said upper mold (21) onto the second table (41) to press the three-dimensionally formed body (14b), cutting the lower layer material (13a) and tacky bonding the three-dimensionally formed body (14b) and the lower layer material (13a). In the apparatus, the second table (41) or the lower mold (42) is provided on the top surface thereof with recessed sections (43), each of which being transversally and inwardly separated from a position where an edge of the first machining means (22) contacts, by 0.2mm to 1mm; and a cushion member (51) being arranged in the respective recessed sections (43).
    • 本发明的目的是提供一种用于制造三维装饰件的方法和装置,其不会损坏装饰件的下层材料的粘合或粘合强度。 该方法包括将上层材料(11a,12a)放置在作为阴极工作的第一台(31)上; 将作为阳极工作的上模(21)下降到第一工作台(31)上以按压上层材料(11a),发射用于感应加热的高频波,以从上部形成三维成形体(14b) 通过成型和熔融切割并将三维成形体(14b)临时保持在上模上; 停止高频感应加热; 将具有粘合性的下层材料(13a)的第二工作台(41)移动到暂时保持三维成形体(14b)的上模具(21)的下方; 并将所述上模(21)下降到所述第二工作台(41)上以按压所述三维成形体(14b),切割所述下层材料(13a)并使所述三维成形体(14b)和所述下模 层材料(13a)。 在该装置中,第二工作台(41)或下模具(42)在其顶面设置有凹部(43),每个凹部(43)从第一加工装置的边缘横向和向内分离 (22)接触,0.2mm〜1mm; 以及设置在各个凹部(43)中的缓冲部件(51)。
