    Abstract: Se presenta un método y un aparato para revestir simultáneamente capas delgadas multiples de fluidos relativamente viscosos, incluyendo adhesivos sensibles a la presion (PSAs), sobre un sustrato en movimiento. El método de la presente invencion comprende el ajuste de los gradientes de presion en la region de la interfaz entre los dos flujos confluentes para evitar la recirculacion. En particular, el gradiente de presion a lo largo del borde medio se regula de tal manera que no sea excesivamente positivo, para posicionar la línea de separacion entre el flujo superior y el flujo inferior en un punto particular en los bordes de troquelado, mejorado así un flujo estable. En el aparato de la presente invencion, se forma una configuracion de escalon en los bordes de troquelado de tal manera que el borde corriente abajo se aleja del sustrato en la direccion de desplazamiento del sustrato. En otro aspecto de la presente invencion, el gradiente de presion en varias ubicaciones en la perla es controlado mediante el achaflanado de los bordes corriente arriba y corriente abajo. En un aspecto adicional de la presente invencion, las viscosidades de los dos líquidos en proceso de aplicacion corresponden a esfuerzos cortantes para promover una buena calidad de revestimiento.

    Abstract: Un método y aparato de revestimiento con troquel que incluye un troquel (100, 150, 220) que tiene una barra inicial (104, 154, 226), con una saliente inicial, una barra central, una barra posterior (108, 158, 232) con una saliente posterior, y una barra de vacío (110, 160, 224). La saliente inicial se forma con un reborde, la primera barra multiple se forma como un filo agudo. La forma del reborde se conforma a la forma de la superficie que es revestida. Al cambiar por lo menos una de las dos alturas H, la proyeccion O y la convergencia C se puede mejorar en desempeño o funcionamiento de revestimiento. El troquel puede tener una superficie de deslizamiento (236, 244) y el fluido de revestimiento puede salir del troquel desde el conducto y deslizarse a lo largo de la superficie de deslizamiento para formar un lecho de revestimiento continuo entre el filo agudo de la barra multiple, la saliente de troquel inicial y la superficie que es revestida. El troquel puede incluir varios conductos para revestir capas multiples.

    Abstract: A longitudinally striated coating on a strip article is produced by advancing the article past an open side of an otherwise-enclosed trench (26) so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the open side of the trench, to keep the trench completely filled and to deposit a layer of coating material on the moving surface of the article. Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials. With delivery of concurrent flows of the two coating materials at each of plural localities spaced along the trench, positional and other variations of the striations can be achieved by varying the relative total flows delivered at different ones of these localities, for example to create a simulated woodgrain pattern.

    Abstract: In the coating of a strip article of indeterminate length, wherein the article is continuously advanced lengthwise past a dam while liquid coating material is supplied to a major surface of the article ahead of the dam, the article is passed through a gap of extended length immediately beyond the dam, the gap being defined between uniformly spaced walls one of which faces the article surface bearing the coating material. The spacing between the gap walls is equal to the thickness of the strip article plus a desired wet thickness of the layer of coating material. Coating material of different colours or shades may be supplied to different portions of the strip surface for producing coatings of varied patterns.

    Abstract: A method and apparatus for simultaneously coating multiple thin layers of relatively viscous fluids, including pressure sensitive adhesives (PSAs), onto a moving substrate. The method of the present invention comprises the adjustment of the pressure gradients in the interface region between two confluent flows so as to avoid recirculation therein. In particular, the pressure gradient along the middle lip is regulated so as to not be excessively positive, in order to position the separating line between the top and bottom flows at a particular point on the die lips, thus enhancing stable flow. In the apparatus of the present invention, a step configuration is formed on the die lips so that the downstream lip steps away from the web in the direction of web travel. In another aspect of the invention, the pressure gradient at various locations in the bead is controlled by beveling the upstream and downstream lips. In yet a further aspect of the present invention, the viscosities of the two liquids being coated are matched at therelevant shear rates to promote good coating quality.

    Abstract: A coating apparatus wherein the coating is made by a coater 1' while a support 2 is carried in a non-contacting manner by a gas jetted from a gas jetting device 3' towards the support 2. The gas jetting device 3' has a hollow housing into which the gas is introduced from a gas source, the wall of the housing adjacent to the support 2 being provided with a plurality of gas jetting nozzle ports 10 through which the gas is jetted towards the support 2, each gas jetting nozzle port 10 having a throat portion 10a presenting a minimum cross-sectional area inwardly spaced from the outer surface 9 of the wall of the housing and an enlarged outlet portion 10b presenting a comparatively large diameter and opening in surface 9 of the wall. The ratio of port area is adjusted in such a manner that the rate of jetting of the gas from unit area of the outer surface 9 of the gas jetting device 3' becomes smaller as the width of the support 2 is increased.
