実施例 １ ポリプロピレン繊維100％よりなる積層された
ウエブを熱融着して得た目付50g／m2、厚さ0.12
m/mの不織布を30m/mの幅にテープ状に裁断し
て不織布テープを得た。この不織布テープを螺旋
装置によりスパイラル状に巻き、重ね部を熱融着
させ、これを所定の長さにカツトし筒状体を作成
した。底板部材は厚さ２m/mのポリプロピレン
繊維100％不織布を円板状に打ち抜いて形成し、
これを前記の筒状体に底部より２m/m程度突出
縁部が出る様に挿入する。次いで、突出縁部を
150〜160℃に加熱された熱板に接触させると、該
突出縁は収縮を生じてカールし、これを底板部材
に向けて押圧すると、突出縁部は底板部材と熱融
着し盲管型セパレータが得られる。
