An apparatus and method are disclosed for finishing a drywall installation which includes providing drywall mud; providing a continuous twisted strand having a plurality of layers of nonwoven fibrous cellulosic material, wherein at least one individual layer of the plurality of layers of nonwoven fibrous cellulosic material contains an accelerant effective for accelerating the setting time of the drywall joint compound; feeding the continuous strand into a cutter and cutting the continuous strand into particles motivated by air pressure so as to generate a stream of cellulosic fibers wherein at least some of the cellulosic fibers contain the accelerant; generating a stream of the drywall joint compound motivated by air pressure; and combining the stream of drywall joint compound with the stream of cellulosic fibers while applying the combined streams onto a predetermined portion of the drywall installation being finished.
L'invention concerne un appareil et un procédé de finition d'une installation à cloisons sèches, qui consiste à: mettre en oeuvre une pâte de jointoyage; mettre en oeuvre un toron torsadé continu présentant plusieurs couches d'un matériau cellulosique fibreux non tissé, au moins une desdites couches contenant un accélérateur pouvant accélérer efficacement le temps de prise du composé de la pâte de jointoyage; acheminer le toron continu vers un couteau et couper le toron continu en particules en utilisant la pression d'air, de façon à générer un flux de fibres cellulosiques, au moins une desdites fibres cellulosiques contenant l'accélérateur; produire un flux du composé de la pâte de jointoyage utilisant la pression d'air; combiner le flux du composé de la pâte de jointoyage avec le flux de fibres cellulosiques et appliquer les flux combinés sur une partie préétablie de l'installation à cloisons sèches faisant l'objet de l'opération de finition.
