Abstract
(DE)
Der Streichrandbegrenzer für eine Kurzverweilzeit-Streicheinrichtung zur Beschichtung laufender Warenbahnen (2), insbesondere auf Papier, dichtet seitlich an beiden Enden eine zwischen Stauwand (4) und Rakelelement (3) gebildete Beschichtungskammer für Streichmasse ab. Die sich auf die Papierbahn ausbildende Auftragszone (12) wird dabei an den Rändern jeweils durch das Formatblech (8) des Streichrandbegrenzers flächig abgedeckt. Der Formatblechhalter (7) ist fest mit dem Dichtklotz (5) verbunden und ragt über die Stauwand (4) nach außen. Der Dichtklotz (5) hat auf der vom Formatblech (8) abgewandten Seite wenigstens eine Vertiefung (11), die durch einen Kanal (13) mit einer Wasserzufuhr (20) verbunden ist. Zwischen Formatblech (8) und Dichtklotz (5) bildet sich ein schmaler, 1 bis 3 mm breiter Dichtspalt (15), wobei das durch die Vertiefung (11) in den Dichtspalt (15) eingeführte Wasser ein Druckpolster erzeugt und das Formatblech (8) flächig an die Papierbahn anpreßt.
(EN)
The invention concerns a painting edge limiter for a painting arrangement with a short residence time for coating continuous material (2), in particular paper. This edge limiter seals laterally at both ends a coating slip chamber which is formed between the barrier wall (4) and doctor blade element (3). The application zone (2) which builds up on the paper web is thus covered flat at each edge by the formatting plate (8) of the painting edge limiter. The formatting plate holder (7) is rigidly connected to the sealing block (5) and projects outwards over the barrier wall (4). On the side remote from the formatting plate (8), the sealing block (5) has at least one depression (11) which is connected to a water supply (20) by a channel (13). A narrow sealing gap (15), 1 to 3 mm wide, is formed between the formatting plate (8) and the sealing block (5). The water introduced through the depression (11) into the sealing gap (15) generates a pressure pad and urges the formatting sheet (8) flat against the paper web.
(FR)
Appareil limiteur latéral pour dispositif d'enduction à court temps de contact, pour l'enduction d'une bande continue de matière (2), notamment de papier, obturant hermétiquement latéralement, à ses deux extrémités, une chambre d'enduction de la matière à appliquer, formée entre une paroi de retenue (4) et une raclette (3). La zone d'application (12) formée sur la bande de papier est ainsi recouverte, à plat, à chaque bord, par la lame de formatage (8) du limiteur latéral. Le support (7) de ce limiteur est relié rigidement à un bloc d'étanchéité (5) et est en saillie vers l'extérieur, au-dessus de la paroi de retenue (4). Le bloc d'étanchéité (5) présente, sur le côté opposé à la lame de formatage (8), au moins une cavité (11) reliée, par un canal (13), à une arrivée d'eau (20). Entre la lame (8) et le bloc (5), il se forme un intervalle étroit d'obturation (15), de 1 à 3 mm de largeur, l'eau parvenant dans cet intervalle (15), par la cavité (11), produisant un rembourrage sous pression et appliquant, par pression, la lame de formatage (8) à plat sur la bande de papier.
