Definitions

  • the present invention relates firstly to a new continuous surface coating process, using a coating composition, of a sheet element such as a sheet of paper, cardboard, or synthetic material. . It also relates to a device allowing the implementation of this method.
  • the surface coating of a sheet element is a common practice in order to improve the qualities of the element, in particular in the case of paper or cardboard.
  • the coating is carried out in a known manner by depositing a coating composition on the sheet element driven in displacement, then by a spreading and smoothing action of the composition in order to obtain a layer thickness also constant as possible.
  • the spreading and smoothing operation is particularly delicate and has been the subject of extensive technical studies with the aim of seeking the elimination of any malformation in the appearance of the layer produced.
  • the present invention provides a new improvement in these coating methods. Indeed, the Applicant has detected that the coating techniques known up to now have a number of unfavorable consequences, on the one hand, at the level of sheet element and, on the other hand, at the level of the layer of material with which the sheet element is coated.
  • the object of the process according to the present invention is to eliminate the drawbacks mentioned above by reducing the contact time of the coating composition with the sheet element before the spreading and smoothing operation as much as possible.
  • the process can also be used for coating paper in a molten medium, that is to say for the application of hot-melt polymers, paraffins, waxes, hot-melt. It also allows carry out these coatings with the aid of pulverulent products subsequently fixed on the support by passage through an oven, for example if it is a hot-melt powder. Coating could also be carried out using foam products.
  • the method of the invention makes it possible to apply the coating composition either on one or on both sides of the sheet element.
  • the method according to the invention is preferably implemented using a known coating device, in particular as described in French patent n ° 2,359,650, in which the sheet element is circulated between two members, at least one of which is constituted by a smoothing blade subjected to a force urging it towards the second member which can be constituted either by a fixed reaction part, or by a roller on which the element is wound sheet, or again by a second blade arranged in opposition to the first blade.
  • the method according to the invention provides the optimum results.
  • the blade moves away from the sheet element from its zone in contact with the latter.
  • the process according to the invention consists, in its general appearance, of injecting the coating composition directly into the corner formed between the blade and the sheet element and as close as possible to the contact zone between the blade and the leaf element.
  • the fact of injecting the composition in the immediate vicinity of the coating area has the additional advantage of maintaining, within the composition, a state of shear which keeps it fluid until it passes under the blade, thus ensuring a more efficient and homogeneous smoothing and consequently a significantly improved coating quality.
  • An important aspect of the invention further lies in the fact that the sheet element is displaced in movement over at least part of its trajectory substantially vertically from bottom to top and that the coating composition is injected also in a direction oriented from bottom to top.
  • This particular arrangement makes it possible to ensure good regularity of the deposition of the coating composition over the entire width of the sheet element while ensuring efficient evacuation of any excess of said composition, without risking seeing form a reserve as would be the case if the injection proceeded from top to bottom with the sheet element scrolling in the same direction.
  • the composition is applied in a manner known per se, by an injector, the outlet orifice of the latter being placed, according to the invention, at or in the immediate vicinity of the contact zone (or smoothing) between the sheet element and the smoothing blade.
  • the outlet of the injector arranged naturally upstream of this zone with respect to the direction of travel of the sheet element, or located at a distance from the outer edge of the blade, as short as possible according to the mechanical requirements imposed by the scrolling of the sheet element and the structure of the injector and oriented towards the top of the angle formed by the blade and the sheet.
  • the invention also relates to a device for coating a sheet element which comprises, in a known manner, a system for continuously guiding and scrolling the sheet element, a means for depositing a coating composition on at least one of the faces of the sheet element, and two members between which the sheet element circulates and at least one of which exerts pressure on the sheet element in order to spread and weave the coating composition , said member being a blade, one end of which is applied against the sheet element and the other end of which is separated from it, the device being characterized in that the means for depositing the coating composition is an injector, the outlet port is directed to the top of the angle formed between the sheet member and the blade.
  • the means for depositing the coating composition is an injector, the outlet port is directed to the top of the angle formed between the sheet member and the blade.
  • the blade will be formed by a flexible and thin blade which is elastically deformable and whose free end in contact with the sheet element will be associated with a pressure member ensuring the flatness of the end. of the blade in contact with the sheet member and its parallelism with said sheet member.
  • the pressure member may consist of a tube containing a fluid under pressure.
  • the pressure member consists of an elastic counter blade, which may be less flexible than the smoothing blade, located outside the smoothing blade, relative to the sheet element, and the free end of which presses on the smoothing blade at the point of contact between said smoothing blade and the sheet element.

  • a flexible blade 8 On one of the edges of the slot is fixed the stationary end of a flexible blade 8, the free end of which is elastically biased in abutment against the sheet 1, downstream of its fixed end in the direction of travel of the sheet, by virtue of the bending of said blade whose convexity is turned towards the roller 2.
  • the arrangement is such that the free end 9 of the blade tangent the curvature of the roui.
  • a pneumatic tube 10 mounted on the body 4 by means of a support 10a (holding the tube over its entire length) exerts pressure over the entire length of the end 9 of the blade.
  • the tube is connected to a source of pressurized air for example, which makes it possible to regulate the pressure exerted on the blade.
  • the fixed end of the blade is spaced from the sheet element and the blade forms a wedge with the latter 11.
  • the edges of the slot 7 formed in the box are inclined, from the inside to the outside, in the direction of travel of the sheet element so that they guide, in the direction of arrow 12, the composition leaving under pressure from the chamber 5 towards the corner 11 formed between the blade and the sheet element.
