【実施例１】以下、本発明の第1実施例について図１に
基づき詳細に説明する。図１に示すように、上受型１に
よって保持されたアクリル樹脂製の上成形体粗材２と、
下受型３によって保持されたＡＢＳ樹脂製の下成形体粗
材４とを、上成形体粗材２の溶着部７および下成形体粗
材４の溶着部８をそれぞれ対向させかつ所要の間隔をお
いて配置し、続いて、上成形体粗材２と下成形体粗材４
との間に、支持部材３によって支持されかつ温度450℃
および温度350℃にそれぞれ発熱された2個の上・下通電
発熱体５・６を進入させる。なお、前記溶着部７は幅2.
2ｍｍ、高さ３ｍｍのリブ構造体であり、また、前記溶
着部８も幅1.5ｍｍ、高さ５ｍｍのリブ構造体である。
次いで、上成形体粗材２を下降させるとともに下成形体
粗材４を上昇させて、2個の上・下成形体粗材２・４
を、溶着部７・８がそれぞれ上・下通電発熱体５・６か
ら１ｍｍ離れた位置に移動させ、さらにその状態を所要
時間維持する。これにより、溶着部７・８を上・下通電
発熱体５・６によってそれぞれ好適状態に加熱して軟化
させる。
【０００８】こうして、上・下成形体粗材２・４の加熱
完了後、上成形体粗材２を上昇させるとともに下成形体
粗材４を下降させ、続いて、上・下通電発熱体５・６を
上・下成形体粗材２・４間位置から後退させる。その
後、再び上成形体粗材２を下降させるとともに下成形体
粗材４を上昇させて、加熱軟化した溶着部７・８を互い
に当接させ、溶着部７・８が冷却されるまで上・下成形
体粗材２・４を押圧する。これにより、２個の上・下成
形体粗材２・４は溶着部７・８にて強固に溶着されるこ
ととなる。
【０００９】
【実施例２】第1実施例における上・下成形体粗材２・
４の材質をＰＰ樹脂に、また溶着部７・８の寸法を、溶
着部７は幅３ｍｍ、高さ５ｍｍに、溶着部８は幅２ｍｍ
、高さ150ｍｍにそれぞれ変え、さらに、上成形体粗材
２と下成形体粗材４の加熱開始時刻を変えて、第1実施
例と同様の溶着を行なったところ、同様に強固に溶着さ
れた完成品が得られた。この場合、上・下通電発熱体５
・６の温度を４５０℃に、溶着部７・８と上・下通電発
熱体５・６とのそれぞれの間隔を1.5ｍｍにして、溶着
部７を30秒間、溶着部８を20秒間それぞれ加熱した。こ
の加熱は同時に完了した。
【００１０】なお、第1実施例において、材質および溶
着部の寸法をそのままとし、溶着部７・８と上・下通電
発熱体５・６との間隔もそのままとし、下通電発熱体６
の温度だけを上通電発熱体５と同じ450℃にして第1実施
例と同様にして溶着を行なった。その結果、ＡＢＳ樹脂
製の肉厚の薄い下成形体粗材４の溶着部８は、過度に加
熱され自重に負けて変形し、部分的にしか溶着されず、
極めて信頼性の劣る溶着であった。
