Definitions

  • the invention relates to a method for structuring the surface of profiles, floor coverings and the like semi-finished products by brushing.
  • the object of the invention is to provide a method for structuring the surface of semi-finished products made of wood substitute materials, for example plastics, wood-plastic composites or the like, in which a typical longitudinal grain of a wood is simulated.
  • the brushing expediently takes place, for example, in the course of an extrusion line, in particular in-line, alternatively, for example for small series, by means of suitable feed units which should ensure a constant but adjustable feed.
  • the number of axially comparatively narrow brushes spaced apart in a row essentially depends according to the width of the surface to be processed. If a large number of brushes of the same type are used, the axial spacing of these brushes is selected to be slightly smaller than the axial dimension of the brush itself. This enables the brushes to overlap with those of a second row following in the transport direction in a simple manner. If further rows of brushes are provided, the distance between the individual brushes in a row can be increased accordingly.
  • the axes of rotation of the brushes are aligned parallel and transversely to the direction of transport, the brushes of each row being expediently arranged on a common axis of rotation and can also be driven together.
  • An image of the surface structuring that largely corresponds to the natural grain of wood is further achieved by the measure that during brushing a brush surface completely engages at least one, preferably all, of the brushes in the surface of the semi-finished products.
  • the bristles of a subsequent brush which axially overlap with a front brush, engage between the grooves introduced by the bristles of the front brush.
  • striations lying next to one another are created offset, the striations being quite recognizable in isolated cases.
  • the arrangement of brushes next to one another further enables, in particular, brushing according to the invention the side bristles of the brushes are allowed to spread apart without support.
  • the radially outer side bristles in particular will migrate axially outward, as a result of which the grooves move apart in the transport direction when the brush is rotated, so that no parallel grooves form as a pattern of grain.
  • the relative speed between the brush surface and the surface to be machined is between 10.0 m / s and 15 m / s. This corresponds approximately to a speed of a brush of approximately 25 cm in diameter between 800 revolutions per minute to 900 revolutions per minute at a feed speed between 1 m / s and 2 m / s.
  • a brush surface essentially becomes one during brushing 'Form the cylinder surface, ie have an axially parallel surface line in a radial view. This can be achieved, for example, by trimming a brush or by inserting bristles of different lengths, and here in particular longer side bristles. Regardless of whether the bristles are smooth or wavy.
  • a device for carrying out the method, in which brushes are spaced apart in a row next to one another and in a further row in the transport direction, transverse to a transport direction of the semifinished products, and in which the brushes are set in a row and overlapped in a row in successive rows are, the axes of rotation of the brushes are aligned parallel and transverse to the direction of transport.
  • Fig.l in a plan view an arrangement of brushes over a semi-finished product
  • FIG. 3 shows a top view of the structuring of a surface of a semi-finished product.
  • FIG. 1 shows a top view of the arrangement of two brushes 1, 2 in a first row 3, which are arranged on a common axis of rotation 4 according to arrow 5 rotating against the transport direction according to arrow 6 of a semi-finished product 7.
  • the brushes 1, 2 are spaced apart and the resulting gap 8 becomes a brush 9 in here a row 10 following in the transport direction 6 of the first row 3 is closed, the adjacent side bristles of the brushes 1, 2 and those of the brush 9 overlapping.
  • the brush 9 rotates according to arrow 11 with the same direction of rotation as the brushes 1, 2 about the axis of rotation 12 against the transport direction 6.
  • the surface 13 of the semifinished product 7, in particular made of a rot-proof material, is not processed over its entire width, which is nevertheless possible.
  • these side bristles 14, 15 can preferably also migrate axially more than centrally arranged bristles and thereby introduce comparatively strongly curved grooves 20, 21 into the surface 13, compare Figure 3.
  • brushes 1, 2, 9, here in an example here in two rows 3, 10 in the transport direction 6 one behind the other allows bristles of the brush 9 on the edge, which overlap those of the brushes 1, 2, between those of the brushes 1, 2 intervene generated grooves.
  • FIG. 2 further shows that the brush surface 24 forms a cylindrical surface. This can be achieved, for example, by suitable trimming. Furthermore, the method according to the invention is independent of whether the brush, as shown, has a corrugated or a smooth wire trim or, if necessary. Wire mixtures. This will be determined regularly by the material to be structured.
  • the cylindrical outer surface 24 of the brush 16 ensures, even at the preferably low speeds, that as far as possible all the bristles come into engagement.
  • a typical speed for such a brush 16 with a diameter of 25 cm is between 800 and 900 revolutions per minute.

Abstract

Procédé de structuration de la surface de profilés, de revêtements de sols et de produits semi-finis analogues à l'aide de brosses, selon lequel des brosses (1, 2, 9) sont placées transversalement à un sens de transport (6) des produits semi-finis (7), les unes à côté des autres à une certaine distance dans une première rangée (3) et en suivant dans le sens de transport (6), dans des rangées supplémentaires (10), les brosses (1, 2, 9) de rangées successives (3,10) étant décalées en face d'un intervalle (8) et placées de manière chevauchante. Les axes de rotation (4, 12) des brosses (1, 2, 9) sont orientés parallèlement les uns aux autres et transversalement par rapport au sens de transport (6), et le brossage de la surface (13) d'un produit semi-fini (7) est effectué contre le sens de rotation (5, 11) des surfaces de brosses.
