Description
前記中空形成部材は、樹脂フィルムで形成されて、前記第1のシートの内面に重なる上面側のフィルムと前記第2のシートの内面に重なる下面側のフィルムが互いに密着する扁平状態とされて、前記第1のシートと前記第2のシートの間に挟まれ、
前記第1のシートおよび前記第2のシートは、扁平状態の前記中空部形成部材の幅寸法と同じ幅寸法で形成された中央領域と、前記中央領域の両側方に形成されて前記中空部形成部材の両側端よりも両側方に延び出る側方領域とをそれぞれ有しており、
扁平状態の前記中空部形成部材の上面側のフィルムが、前記第1のシートに形成された中央領域と接合されるとともに、前記中空部形成部材の下面側のフィルムが、前記第2のシートに形成された中央領域と接合され、前記第1のシートに形成された前記側方領域と、前記第2のシートに形成された前記側方領域とが、前記中空部形成部材の両側端の外側で互いに接合されており、
前記中空部形成部材の上面側のフィルムと下面側のフィルムとの間に、前端と後端に開口部を有する中空部が形成されていることを特徴とするものである。
(a)樹脂フィルムで形成されて扁平状態とされた中空部形成部材の上面側のフィルムと第1のシートに形成された中央領域とを接合して接合体を形成する工程と、
(b)前記接合体を構成する前記中空部形成部材の下面側のフィルムと第2のシートに形成された中央領域とを接合するとともに、前記第1のシートの前記中央領域の両側方に形成された両側方領域と、前記第2のシートの前記中央領域の両側方に形成された両側方領域とを、前記中空部形成部材の両側端よりも外側において互いに接合して、
扁平状態の前記中空部形成部材が前記第1のシートと前記第2のシートとの間に挟まれて、上面側のフィルムと下面側のフィルムとの間に中空部を有する中空体を形成する工程。
2のシートとを接合して、中空部形成部材を前記第1のシートおよび前記第2のシートによって補強することができる。そのため、強度が向上された中空体を製造することができる。
また、前記(a)工程と前記(b)工程とを同時に行なうこともできる。
図1に示すように、前記中空体1は、図示X1−X2方向に所定の間隔を有する幅寸法を有し、図示Y1−Y2方向に向かって連続して延びて形成されている。前記中空体1では、図示Y1−Y2方向が長手方向となり、図示X1−X2方向が幅方向となる。
図6に示す中空体601は、図1に示す前記中空体1と同じ構成要素を有して構成されている。したがって、図6に示す中空体601の構成要素のうち、図1に示す前記中空体1と同じ構成要素には、同じ符号を付して詳しい説明を省略する。
図9に示す中空体701は、図1に示す前記中空体1と同じ構成要素を有して構成されている。したがって、図9に示す中空体701の構成要素のうち、図1に示す前記中空体1と同じ構成要素には、同じ符号を付して詳しい説明を省略する。
