Description
上記接合用の突部は、伸張時の弾性部材を搬送溝内に収容できるように、例えば、100μm以上の高さで形成される。
前記アンビルロール50と協働して前記一対のシート1,2を互いに融着すると共に前記一対のシートで前記弾性部材Fを保持させる融着装置70とを備え、
前記アンビルロール50の外周面51には、前記一対のシート1,2が前記互いに接合された第1接合部31を生成するための第1突部52Hが前記アンビルロール50の幅方向Sに沿って、かつ、幅方向Sに互いに離間した状態で複数配置され、
前記各第1突部52Hは、前記アンビルロール50の周方向Rに延び、前記弾性部材Fが入り込んだ状態で前記弾性部材Fを搬送する搬送溝Gを定義すると共に包含し、
前記搬送溝Gを含む前記複数の前記第1突部52Hのうち、前記幅方向Sに互いに隣り合う1つの第1突部52Hと別の第1突部52Hとの間に前記一対のシート1,2を受け止める少なくとも1つの受止部52Lが配置されている。
前記製造方法は以下の工程を備える。すなわち、本方法は
前記第1シート1をアンビルロール50上に導入する工程、
前記アンビルロール50上の前記第1シート1上に前記弾性部材Fを導入すると共に前記アンビルロール50の複数の前記搬送溝Gの各搬送溝Gに前記弾性部材Fの各々が入り込むように前記弾性部材Fを導入する工程、
前記第1シート1が前記アンビルロール50の径方向に収縮するのを抑制するために、前記搬送溝Gを包含する1つの第1突部52Hと別の第1突部52Hとの間の受止部52Lにおいて前記第1シート1を受け止めながら、前記第1シート1および前記弾性部材Fを搬送する工程、
前記アンビルロール50上において、前記第1シート1と第2シート2との間で前記弾性部材Fを挟むように前記第2シート2を前記第1シート1上に導入する工程、並びに、
前記受止部52Lにおいて前記第1シート1と第2シート2とが融着されることなく、第1シート1と前記第2シート2とを前記アンビルロール50の前記第1突部52H上で融着して前記第1接合部31を形成する工程を備える。
前記搬送溝Gの深さは前記一対のシート1,2と両者の間の前記弾性部材Fとが互いに融着される程度の深さであってもよいし、互いに融着されない程度の深さであってもよい。前記搬送溝Gにおいて前記一対のシート1,2と前記弾性部材Fとが互いに融着される場合、前記搬送溝Gの底面は前記第1突部52Hで定義される。すなわち、この場合、前記搬送溝Gは前記幅方向Sの両側および下側において前記第1突部52Hに囲まれている。
なお、前記搬送溝Gは1つの第1突部52Hに対し複数設けられてもよい。
アンビルロール上において、シートが接合用の突部間の受止部に受け止められる。そのため、シートおよび弾性部材Fがアンビルロールの軸方向(幅方向)に変位することが抑制される。この結果、弾性部材が搬送溝から外れることが抑制され、接合時に弾性部材の破断が防止されるだろう。
前記少なくとも2つの受止部52Lの間に、前記一対のシート1,2が互いに接合された第2接合部32を生成するための第2突部52Sが設けられている。
受止部52Lの高さが第1突部52Hに比べ低すぎると、第1シートを受止部52Lで受け止めるまでに第1シートが弾性部材Fと共にアンビルロール50の径方向に縮まろうとし、アンビルロール50の軸方向に弾性部材Fが変位し易くなる。
一方、受止部52Lの高さが第1突部52Hと同程度まで近づくと、シートの厚さや種類にもよるが、受止部52Lにおいて一対のシートが互いに融着し易くなり、互いに接合されてしまう。
まず、弾性部材Fが伸張した状態について説明する。
図4Aの製造装置はアンビルロール50、導入装置60および融着装置70などを備える。
図8Bにおいて、前記搬送溝Gは前記第1突部52Hに形成されたノッチで定義されている。前記第1突部52Hのノッチの最下面は、破線で示す前記凹溝59の底面よりも前記ロール50の径方向に突出した高さに設定されている。前記受止部52Lの表面は前記ノッチの前記最下面よりも前記径方向に突出した高さで、かつ、前記第1突部52Hの突出表面よりも前記径方向に退避した高さに設定されている。
図10(a)のように、受止部52Lの形状は方形以外の円形等であってもよい。また、受止部52Lは各第1突部52Hよりも周方向に突出していてもよいし周方向に短くてもよい。
たとえば、導入用のロールは必ずしも設ける必要はない。また、融着は超音波ではなく、熱シールであってもよい。
したがって、そのような変更および修正は、請求の範囲から定まる本発明の範囲内のものと解釈される。
