Title (EN) IMPROVEMENTS IN JET STRIPPING APPARATUS
(FR) AMELIORATIONS APPORTEES A UN APPAREIL D'ELIMINATION PAR JET
Abstract:
(EN) A flow diversion device for a gas jet stripping apparatus is used to minimise edge build up when coating a moving strip. The device includes a baffle (17) having a first portion (18) extending longitudinally of the moving strip (4) and adjacent the strip, a second portion (19) extending from the first portion diverging away from the edge of the strip and a gas supply duct (20) communicating with the strip side of the baffle (17) for providing gas to at least second portion (19) of the baffle. It is preferred that the gas from the duct (20) is supplied with a velocity component in the counter direction of travel of the moving strip.
(FR) On utilise un dispositif de déviation de flux pour un appareil d'élimination par jet de gaz pour minimiser l'accumulation sur les bords lorsque l'on enduit une bande en mouvement. Le dispositif comporte une chicane (17) présentant une première partie (18) s'étendant longitudinalement par rapport à la bande en mouvement (4), de manière adjacente par rapport à cette dernière, une deuxième partie (19) s'étendant depuis la première partie et divergeant du bord de la bande et un conduit d'alimentation en gaz (20) communiquant avec le côté bande de la chicane (17) pour envoyer du gaz à au moins la deuxième partie (19) de la chicane. Le gaz provenant du conduit (20) présente de préférence une composante de vélocité à contre-sens par rapport au sens de déplacement de la bande en mouvement.
