Abstract

Un aparato para formar artículos fibrosos tendidos al aire. El aparato puede tener un bolsillo del núcleo relacionado operativamente con un distribuidor de aire que puede aplicar diferentes presiones de aire a diferentes porciones del bolsillo del núcleo. El bolsillo del núcleo puede tener un revestimiento y una abertura central definida por un hueco en el revestimiento. El bolsillo del núcleo puede tener una superficie formadora porosa central que se comunica con la abertura central por medio de flujo de aire y tiene una periferia de la cámara formadora central. El bolsillo del núcleo puede tener una superficie formadora porosa central que se comunica con la cámara formadora central por medio de flujo de aire. El bolsillo del núcleo puede terne un par de aberturas en los bordes que se extienden a lo largo del revestimiento. El bolsillo del núcleo puede tener una cámara formadora marginal que está dispuesta alrededor del la periferia de la cámara formadora central y que se comunica con las aberturas en los bordes por medio de flujo de aire. El bolsillo del núcleo puede tener una superficie formadora porosa marginal comunicada con la cámara formadora marginal por medio de flujo de aire.
