Definitions

  • the present invention relates to a device for continuously applying a coating layer on a strip of material circulating between two rotary cylinders bearing against one another, having a speed of rotation equal to the speed of movement of the strip and one of which is the applicator cylinder of the coating layer, of the type comprising a reserve containing a coating product, a first roller for continuously withdrawing from the reserve a metered quantity of product, means for drive the pick-up roller at a preset constant speed of rotation, and means for transferring the product picked up by the pick-up roller onto the applicator cylinder.
  • US-A-3 647 525 illustrates the prior art since it describes a device making it possible to apply a liquid or slightly viscous product to a moving strip, but which cannot be used satisfactorily for making coatings of thin with a very viscous product.
  • the present invention proposes to memorize this gap and, to do this, it relates to a coating device of the aforementioned type, which is characterized in that the transfer means comprise a second roller situated between the pick-up roller. and the applicator cylinder, which extends parallel to them but bears only against the applicator cylinder, and a third roller pressing against the pick-up roller and the second roller, the third roller being mounted idly while the second roller is rotated by means rotating it in the same direction as the pick roller.
  • the first roller continuously draws from the reserve a constant quantity of product which it directs towards the third roller.
  • the latter then carries with it the product which it receives from the first roller and directs it to the second roller.
  • the second roller drives the product it receives from the third roller and directs it towards the cylinder which applies it against one of the faces of the moving strip.
  • the layer of product deposited by the third roller on the second will be thinner as the latter will rotate faster than the first roller.
  • the speed of the first roller it is therefore possible to give the thickness of the layer of product transferred to the second roller, and therefore to the strip, a constant value which may be very low.
  • the coating device further comprises means for adjusting the pressure of the third roller on the first and second rollers.
  • This other arrangement makes it possible to act even more precisely on the thickness and the regularity of the layer of coating product deposited on the strip.
  • By properly adjusting the intensity of the pressure with which the third roller rests on the first and second rollers it is indeed possible to modify the amount of product that can be transferred from the first to the second roller and therefore to control with greater high accuracy the thickness and regularity of the layer deposited on the strip.
  • the third roller is carried at each of its ends by bearings supported by levers articulated on the axis of the first roller, each bearing being movable radially relative to the first roller under the action of a first pneumatic cylinder, while each lever is able to pivot around the axis of the first roller under the action of a second pneumatic cylinder.
  • the pneumatic cylinders make it possible to precisely measure the pressure exerted by the third roller on the other two.
  • At least one of the rollers it is also advantageous for at least one of the rollers to contain heating means. Indeed, when the coating product is highly viscous, it is thus possible to lower its viscosity so that its application on the strip can be carried out under the best conditions. Tests have shown that it is desirable to reduce the viscosity of the product around 2500 centipoises or 2.5 poiseuille (m- 1 - kg. S- ⁇ .
  • the third roller has a length equal to the width of the strip and is shorter than the other two rollers, the length of which corresponds to that of the cylinders for the passage of the material to be coated.
  • the coating product is thus applied to the second roller only over a length equal to the width of the strip. It follows that the maintenance or cleaning operations of the second roller and of the cylinder which bears against it thus become easier.
  • the reserve of product extends between the first roller and a roller immobilized in rotation and applied against the latter by adjustable clamping means.
  • adjustable clamping means By properly adjusting the clamping pressure exerted between the fixed roller and the first roller, it is of course possible to control the flow rate of the coating product withdrawn from the reserve.
  • the coating device which can be seen in the drawing makes it possible to apply a layer of product, for example an adhesive without solvent, on a strip of material 1 circulating at constant speed between two cylinders 2 and 3 resting on the 'one against the other and whose speed of rotation is equal to the speed of travel of the strip.
  • the strip 1 the tension of which is adjusted in a manner known per se, passes over a drive cylinder 4 located upstream of the cylinder 2 and between two driving cylinders 5 and 6 located downstream of the cylinder 2 and at which a another strip of material 7 is applied against the coated face of the strip 1.
  • the coating device comprises a reserve 8 containing the coating product, a first roller 9 associated with the reserve 8 for continuously withdrawing a metered amount of product therefrom, a second roller 10 pressing against the cylinder 3 and spaced from the cylinder 9, and a third roller 11 mounted idly, resting on the rollers 9 and 10.
  • a DC motor M i which is connected to a source not shown by means of a current controller V and a potentiometer P, is provided to drive the roller 9 with a preset constant speed of rotation.
  • a second direct current motor M 2 supplied by means of the variator V, makes it possible to drive the roller 10 with a constant rotational speed equal to the running speed of the strip 1.
  • the idler roller 11 is carried at each of its ends by bearings 12 mounted on levers 13 articulated on the axis of the roller 9.
  • Each bearing 12 is connected to the rod 14 of a pneumatic cylinder 15 carried by the corresponding lever 13 and can therefore move radially relative to the roller 9 when the jack 15 is actuated. It goes without saying that the actuation of the jacks 15 makes it possible to dose the pressure of the roller 11 against the roller 9.
  • each lever 13 is articulated at the free end of the rod 16 of another pneumatic cylinder 17 whose body is articulated on the frame 18 of the coating device.
  • the jacks 17 it is also possible to measure the pressure of the roller 11 on the roller 10.
  • the reserve of product 8 is limited laterally by the roller 9 and a roller 19 immobilized in rotation against the roller 9 by adjustable clamping means not shown.
  • the roller 19 is preferably mounted on free wheels thanks to which it can easily be brought into another immobilized position.
  • At least one of the rollers 9, 10 and 11 is also provided with heating means such as internal channels allowing the circulation of a heat transfer fluid.
  • heating means such as internal channels allowing the circulation of a heat transfer fluid.
  • the roller 11 has a length equal to the width of the strip 1 but is shorter than the rollers 9 and 10 which are as long as the cylinders 2 and 3.
  • roller 19 is preferably made of "Hypalon", while the roller 9 is made of chromed steel, that the roller 11 is made of elastomer, that the roller 10 is rubberized, that the cylinder 3 is made of steel and that cylinder 2 is rubberized.
  • the coating device it is possible to deposit on strips of very diverse materials, a very thin coating layer, even when the product to be deposited has a high viscosity. It suffices in fact to suitably adjust the speed of rotation of the roller 9 relative to that of the roller 10 and to judiciously dose the pressure that the roller 11 exerts on the rollers 9 and 10.
  • the coating device according to the invention can be used to deposit a layer of product on strips of different widths. It suffices to provide it with a roller 11 whose length is equal to the width of the strip to be coated. It can also function satisfactorily whatever the speed of travel of the strip 1. In this case, it suffices to act on the variator V so that the motor M 2 drives the roller 10 with a rotational speed. equal to the running speed and act on the potentiometer P to give the ratio of the speeds of rotation of the rollers 9 and 10, a determined constant value.
  • the coating device which has just been described is more particularly intended for applying a layer of a product such as a solvent-free adhesive on a strip circulating between two cylinders pressing against each other. It goes without saying, however, that it is not limited to this particular application and that it could also be used in the case where the coating product would be an ink and the strip of material would consist of a plate mounted on cylinder 2.
