Definitions

  • the present invention relates to a coating agent for applying a material to a substrate, comprising a rotatably storable cylindrical roller.
  • Such application means in the form of a roller for applying a material to a substrate, in particular for applying liquid to pasty deposits on a substrate, are known from the prior art.
  • Such coverings may, for example, have many different types of screeds for building any type of indoor and outdoor flooring, for example synthetic resin, plastics, cement, mastic asphalt, and others.
  • the present invention is therefore based on the object to alleviate at least one of the disadvantages listed above.
  • the present invention has for its object to provide a contract agent, which allows a complaint-free order and is easy to handle.
  • a coating means of the aforementioned type is proposed, which is developed such that the lateral surface of the roller has at least one coil extending inwards in the lateral surface.
  • the helix causes a quasi-induced, automatic forwarding of the order material on one side, thus the force required for the operator is reduced because not all the excess application material has to be pushed in front of the roller.
  • the support surface Due to the special shape of the lateral surface, the support surface is raised to the ground and thus the roller rolls off better and does not slip over the ground. On the other hand, it is prevented by the induced sideways conveying the excess application material that the roller runs on the otherwise jammed before the roll material or slip over. Due to such slipping, otherwise the job would become unusable due to the abruptly increasing layer thickness and would have to be repeated.
  • a helix in the context of the present invention is understood to mean a curve which winds with a slope around the mantle of a substantially cylindrical body.

  • a recess may be designed as a blind hole to receive a stub axle. Both opposite end faces may each have such a blind hole to engage from both sides with a suitable device according to the roll and to be able to roll it on a substrate.
  • the recess can also be designed as a through hole for the passage of an axle. Further possible embodiments are described below.
  • a pitch of the helix in the areas between 1-100mm, preferably 2-70mm, more preferably 5-15mm, can be realized.

  • a sectionally different pitch height you can achieve different sideways conveying speeds of the order material.
  • the helix has a different pitch in sections.
  • desired conveying effects and an optimal adaptation to the behavior of the order material can be achieved.
  • more application material will usually be incurred, which has to be conveyed to the side. This can be compensated for with a different pitch of the helix in the middle region of the roll compared to the edge region.
  • the helix on the left and / or right running, or a combination of both realized one can influence the sideways promotion of the application material directionally.
  • the layer thickness of the application material can be determined.

  • the surface area of the negative form of the helix may preferably be in the range of 1-150 mm 2 , preferably 1.5-70 mm 2 , particularly preferably 2-40 mm 2 , and directly influences the application rate of the application material, whereby an adjustment to the viscosity of the Order material can be realized.
  • At least one longitudinal groove extending in the longitudinal axial direction of the roller is arranged on the lateral surface of the roller.
  • a longitudinal groove is understood to mean a groove in the lateral surface which extends parallel to the longitudinal axis of the roller.
  • a multiplicity of, preferably equidistantly distributed, longitudinal grooves can be applied or incorporated on the lateral surface.
  • the proposed longitudinal groove or longitudinal grooves can further improve the sideways conveying of the application material and / or increase the quality of the order.
  • the longitudinal grooves also prevent the roller from floating on the application material.
  • longitudinal grooves increase the Adhesion of the roller to the substrate and prevent unwanted slippage of the roller.

  • Advantageous embodiments of the invention which have the above-mentioned cones on the lateral surface of the roller, show the advantage that when applied a taching effect can be set in the processed application material.
  • a taching effect can be set in the processed application material.
  • a particularly favorable venting effect in the application material can be achieved.
  • the application material is aerated and it forms for a short time (immediately after pulling out the pin and before the flow of the material) the peg preformed channels through which air trapped in the application material can escape. Even so, a particularly good and perfect order can be achieved.
  • a concrete, preferred embodiment comprises a roller having a length of 400-500mm, preferably 450mm.

  • the outwardly directed corners of the pins are further rounded. If an embodiment of the application agent according to the invention is used which has cones on the lateral surface of the roller, the following effect could, if appropriate, be observed with a few special application materials. When rolling the roller in or over the application material outwardly facing corners or side edges of said pin could tend due to their shape and the surface tension of the processed material that "take along" order material or entrain upwards. Thus, the application material could possibly be pulled thread-like from the corners of the pin from the job until the formed thread breaks and the material falls back onto the substrate. The result could be point-shaped imperfections in the job, which may no longer be completely leveled by flowing. The rounding of the pins proposed here prevents such adhesion or favors an early detachment of the application material from the pins and thus favors a particularly uniform and error-free application.

  • the longitudinal grooves can also be configured continuously.
  • the cross-sectional surfaces of the helix and / or of the longitudinal grooves in such a way that the surface widens in the direction of the outer side of the roll, and preferably widens with a convex, possibly circular curvature. This can result in particularly good rolling properties of the roller. Furthermore, sensitive surfaces are not damaged because the roller has no sharp edges, corners or tips that could touch the ground.
  • the helix and / or the longitudinal grooves can, according to a further advantageous embodiment, be formed by means of a milling head with a substantially convex cross-sectional area, optionally with a cylindrical lower end.
  • a helix and / or longitudinal grooves can be produced with a cross-sectional shape discussed in the preceding section.
  • a simple wear indicator or a wear indicator is realized in order to recognize when the roller no longer applies the desired thickness of the material. As soon as the web terminates together with the lateral surface of the roller, the user immediately recognizes that the wear limit of the roller has been reached and the desired thickness of the application layer is no longer guaranteed from then on. In this case, the roller must be replaced or reworked if necessary.
  • longitudinal grooves and / or the helices may optionally have one or a plurality of interruptions of the longitudinal grooves of lesser depth.
  • These webs can serve as an indication of the state of wear of the roller (namely as wear indicators).

This effect also causes not the entire application material has to be pushed in front of the roller 10, but passes the Surplus to one side. This creates only an overflow track.
  • Advantageous formations (in particular helix 14 and / or longitudinal grooves 20 and / or, particularly preferred, pin 24) of the lateral surface 12 also cause a distribution and a daching and venting of the application material. Furthermore, so unevenness of the ground are compensated, since the roller spans by its span recesses of the ground and at these points automatically more application material remains lying, which fills the unevenness. After completion of the work iA cleaning of the roller 10 is generally necessary.
