This invention relates to a lamination apparatus and in particular to a dual belt driven, continuous pressure lamination apparatus that utilizes pressure, heat and cooling to bond at least two substrates (plies) with an adhesive between the layers of the substrates. The pressure laminator of the present invention has been specifically designed to permit the permanent joining of at least two fabric substrates with an adhesive between the fabric substrates, with little or no shrinkage occurring during the lamination process. The resulting non-woven fabric advantageously has the appearance of a woven fabric, but has superior strength characteristics there over. The pressure laminator of the present invention can have other uses, for example, printed circuit board substrate manufacture, and the like, as will be appreciated by those having ordinary skill in this art.
L'invention concerne un appareil de contrecollage, et notamment un appareil de contrecollage à pression continue entraîné par deux courroies utilisant la pression, la chaleur et un refroidissement pour lier au moins deux substrats (plis) au moyen d'un adhésif situé entre les couches desdits substrats. La contrecolleuse à pression de la présente invention est spécialement conçue pour permettre l'assemblage permanent d'au moins deux substrats de tissu au moyen d'un adhésif situé entre ces substrats de tissu, ce processus de contrecollage n'occasionnant qu'un faible retrait, voire aucun. Le tissu non tissé résultant présente avantageusement l'apparence d'un tissu tissé, mais offre une résistance plus élevée que ce type de tissu. La contrecolleuse à pression de cette invention peut revêtir d'autres fonctions, telles que la fabrication de substrats pour cartes à circuits imprimés, etc., comme le constateront les personnes versées dans la technique.
