An apparatus (10) is provided for permitting a substantially continuous flow of drywall compound (13) to a wallboard joint. The apparatus includes a delivery tube (12) for delivering drywall compound completely therethrough. The delivery tube has a first end connected to a drywall compound supply assembly (20, 22, 26) fed directly by a source (32) of pressurized drywall compound. The delivery tube also has a second end opposite the first end in communication with a drywall compound dispensing head (51). A normally closed, pressure sensitive valve arrangement (36) is interposed between the second end of the delivery tube and the dispensing head for controlling the starting and stopping of drywall compound flow between the delivery tube and the dispensing head.
L'invention concerne un appareil (10) permettant un écoulement sensiblement continu d'un composant de mur sec (13) dans un joint de panneau mural. Cet appareil comprend un tube de distribution (12) pour distribuer, de manière complète, un composant de mur sec à l'aide de ce dernier. Le tube de distribution présente une première extrémité reliée à un assemblage de fourniture de composant de mur sec (20, 22, 26) alimenté directement par une source (32) du composant de mur sec pressurisé. Ce tube de distribution présente également une seconde extrémité opposée à la première extrémité, en communication avec une tête de distribution de composant de mur sec (51). Un agencement de vanne sensible à la pression (36), normalement fermé, est intercalé entre la seconde extrémité du tube de distribution et la tête de distribution pour commander le départ et l'arrêt de l'écoulement de composant de mur sec entre le tube de distribution et la tête de distribution.
