Patent

CA 2138994

The invention relates to a paper colouring apparatus for especially water colours or water-based inks, wherein a driven running paper web (1) is positioned around a turning roller (2) constituting the counter pressure roller for an inker (3) and, together with the latter, are included in a roller train (4) adapted to convey ink (8) from a reservoir (9) to the inker (3). One has aimed at transferring ink to the paper (1) in so small amounts that after-drying of the paper (1) becomes unnecessary. According to the invention, said roller train (4) is adapted to be driven by means of the running paper web (1) and comprises five or more rollers (2, 3, 5, 6, 7).

L'invention se rapporte à un appareil de coloration du papier conçu notamment pour les couleurs à l'eau ou pour les encres à base d'eau, dans lequel une bande de papier se déroulant (1) est positionnée autour d'un rouleau rotatif (2) constituant le rouleau à contre-pression d'un rouleau encreur (3) et qui, avec ce dernier, est incluse dans une série de rouleaux (4) adaptés pour transporter l'encre (8) d'un réservoir (9) vers le rouleau encreur (3). Le but est de transférer l'encre sur le papier (1) en de si petites quantités qu'un après-séchage du papier (1) ne s'avère pas nécessaire. Selon l'invention, cette série de rouleaux (4) est conçue pour être entraînée au moyen d'une bande de papier à déroulement (1) et comprend au moins cinq rouleaux (2, 3, 5, 6, 7).
