る。
上記いずれの場合も、第３図、第４図で突条４
０の下縁を結んだ線Ａが水平線Ｂに対してなす角
度αは1.5゜程度であり、ホツトメルト接着剤の粒
３２の下端は突条４０の下縁よりも下に突出す

これによつて摩擦熱で溶けたホツトメルト接着
剤は、フアスナの高速回転による遠心力で摩擦接
着板の下面の中心部から外周縁部に向かつて、渦
巻形の突条４０の各一巻き宛の内部を満たしなが
らその下を潜つて逐次外に拡がり、摩擦接着板の
下面全体に均一に行き渡る。
そして、溶けたホツトメルト接着剤が摩擦接着
板の下面の外周縁部から外にはみ出すのを防止す
るため、摩擦接着板の下面外周縁部に沿つて下向
きの環状リブ４４を設け、この環状リブ４４の下
縁を渦巻形の突条４０の最も下に位置する下縁よ
りも下に位置させて置けばよい。尚、この場合は
ホツトメルト接着剤の粒３２の下端を第１図で明

よい。勿論、同心の円形や多角形の場合も外側の
突条ほど下縁の位置を下げて置く。
〈発明の効果〉 以上で明らかなように本発明はホツトメルト接
着剤を摩擦熱で溶かして摩擦接着板の下面を物体
に固定するため、物体が金属やプラスチツクの場
合は勿論、木材であつても、或いは物体の表面に
塗装がされていても接着が行なえる。
そして、摩擦接着の際、溶けたホツトメルト接
着剤は回転により発生する遠心力で摩擦接着板の
下面の中心部から外周縁部に向かつて、渦巻形
か、内外多重の同心の円や多角形の突条の各一巻
き宛の内部を満たしながら突条の下を潜つて逐次
外に拡がり、摩擦接着板の下縁面全体に行き渡る
ため摩擦接着板の下面を頗る強力に固定すること
ができる。
