Definitions

  • the present invention concerns a brush and a method for manufacturing such a brush.
  • the invention concerns a rotating brush for brushing a pavement surface, which brush, as is known, is suspended under a vehicle, such that, as a result of the movement of the vehicle and the rotation of the brush, a large surface of the pavement can be treated in a short time by means of such a brush.
  • rotating brushes designed to be implemented when carrying out heavy brushing operations, for example for brushing loose, brushing away respectively, weeds growing from out of the road surface, as well as for brushing away grass and weeds growing rank as of a roadside or the like over the edge of a road surface.
  • a first disadvantage consists in that they may come loose and/or tear at the top end where they are fixed, as a result of which the desired effect is lost.
  • a major disadvantage is that such brushes are relatively expensive as they require a large number of assembly operations, among others because the above-mentioned cases have to be slid one after the other over the bundles of fibres and then have to be separately fixed.
  • US 4.144.610 discloses a bristle of a sweeping device for use in maintaining railroad rails, which bristle is attached to a flex-limiting plate by means of a clamp which is screwed against said plate and SE 0.451.607 discloses a weed removal brush which is provided with a number of brushes each of which is clamped in a brace by means of a screw and the brace is suspended on a plate by means of a hook attachment.
  • Such devices contain a lot of corners and spaces wherein dirt and moisture can accumulate, leading to corrosion problems.
  • the present invention aims a brush which is more efficient, both from a point of view of its construction and from a point of view of the manufacturing, than the embodiments known until now, and whereby, in particular, also the above-mentioned disadvantages are excluded.
  • the invention concerns a brush according to claim 1
  • a coating is meant a casing according to the invention which, as will become clear from the preferred embodiments described hereafter, fits tightly around the bundle of fibres, as opposed to the conventional cases which fit loosely over the bundles of fibres with a play of a few millimetres.
  • this casing is also made such that it offers sufficient resistance in order to prevent an undesired, considerable unravelling.
  • fibre twines or cables which are already coated and which are possibly available on the market can be taken as a basis, which only remain to be detached at the required lengths.
  • fibre twines for example twisted cables
  • fibre twines can be taken as a basis which are especially provided with a coating in order to realise the aforesaid brush and which are then, as mentioned above, cut to pieces of the required length.
  • the coating is made of plastic, in particular plastic which has cured around the bundles of fibres or the fibre twine out of which these bundles of fibres have been made, such that a good adhesion between the coating and the fibre twine is automatically obtained.
  • the coating may consist of a shoe-like structure, woven or wrapped around the bundles of fibres, made of any suitable material whatsoever, for example made of thin metal wire.
  • the invention is in the first place meant for rotating brushes with bundles of fibres which consist as such of metal, in particular plaited, twined or twisted cable parts, it is not excluded to apply it in combination with bundles of fibres which are made as such of another material than metal.
  • the bundles of fibres are contained in holders which are in turn fixed to a part of a brush body.
  • This fastening preferably takes place by providing the holders through openings in the aforesaid part of a brush body and by welding them in these openings.
  • the aforesaid fastening offers several advantages, namely that it is rigid, that the holders, by sticking them in the holes, automatically take up the right position, such that the use of jigs for positioning the holders during the welding can be excluded, and that the holders can be welded quicker and more easily to the brush body, such that this results in an additional reduction of the production time.
  • the present invention also concerns a method for manufacturing a such brushes, characterised in that, for the formation of the bundles of fibres of this brush, a coated fibre twine can be taken as a basis, preferably a plasticised fibre twine, and more in particular a plasticised twined or twisted steel cable, of which pieces at the length of the fibre bundles concerned are detached, in particular cut off; and in that, subsequently the bundles of fibres are provided in bush shaped holders at one far end, with which they are in turn fixed to a part of a brush body.
  • a coated fibre twine can be taken as a basis, preferably a plasticised fibre twine, and more in particular a plasticised twined or twisted steel cable, of which pieces at the length of the fibre bundles concerned are detached, in particular cut off; and in that, subsequently the bundles of fibres are provided in bush shaped holders at one far end, with which they are in turn fixed to a part of a brush body.
  • This method is particularly efficient, for it excludes the conventional time-consuming operation of applying and fixing separate cases. Moreover, the bundles of fibres do not have to be provided with a coating one after the other.
  • the coated fibre twine which is taken as a basis to form bundles of fibres, may consist of a product which is available on the market, or it can be especially made beforehand in view of the invention.
  • a continuous fibre twine or cable is first provided with a coating and then divided in pieces of the required length.
  • the coating can be applied in any way whatsoever, for example by extruding a plastic covering around the fibre twine or cable, by wrapping a plastic strip around the fibre twine and by fusing it around the fibre twine by means of heat, by applying one or several plastic shrinkage shoes around the fibre twine, etc.
  • the known brush 1 represented in figures 1 to 3 mainly consists of a part of a brush body 2 on the one hand, in this case a plate, which can be fixed to a rotating part 4 attached to a vehicle by means of fasteners 3, in this case bolts, and of bundles of fibres 5 on the other hand.
  • the bundles of fibres 5 consist of lengths of twined steel cable which are clamped in holders 6 at their top ends, which are in turn welded to the lower side of the part of the brush body 2.
  • These holders are bush-shaped and have a top end 8 which is cut slantwise in relation to their longitudinal axis 7, such that, when they have been welded under the part of the brush body 2, they will extend at an angle, as represented.
  • the bundles of fibres 5 are each provided with a casing formed of a plastic case 9 slid over each bundle of fibres 5 concerned.
  • the inner diameter of these cases is a few millimetres larger than the average diameter of the bundles of fibres 5.
  • the cases 9 are fixed as they are slid with their top ends over the accompanying holder 6, and as they are fastened by means of a straining ring 10, usually in the shape of a ring pressed around it.
  • This known embodiment of a brush 1 has several disadvantages, as explained in the introduction.
  • This brush 1 is built in an analogous manner as those of figures 1 to 3 from a part of a brush body 2 and bundles of fibres 5 provided in holders 6 attached to it.
  • the invention is special in that the casing of the bundles of fibres 5 is no longer formed of a separate case 9, but of a coating 11 formed directly around every bundle of fibres 5, in this case made of plastic, preferably a somewhat flexible plastic.
  • the bundles of fibres 5 preferably consist of metal, in particular lengths of twined cable, composed of twined cable parts 12, in this case seven in number, which are each composed of bundles of thin steel wire 13. It is clear that the bundles of fibres 5 can have different diameters, but in practice they will usually have a diameter of 1 to 4 cm.
  • the coating 11 may consist of plastic cured around the bundles of fibres 5 and which thus fits closely to the outer side of these bundles of fibres 5. In combination with these bundles of fibres 5 which consist of a twined cable part, as represented in figures 4 to 8 , this offers the advantage that the plastic coating 11 is particularly well anchored around the actual bundle of fibres 5, as this plastic reaches into the deeper parts 14 situated on the outer perimeter.
  • the bundles of fibres 5, together with the part of the coating 11 which is situated there, are contained in the holders 6, in particular they are clamped therein as these holders 6 are pressed together around the coated bundles of fibres 5.
  • this coating 11 can possibly be removed at the top end of every bundle of fibres 5 concerned, although this is not necessary in practice.
  • the holders are also provided with a far end 8 extending slantwise in relation to the longitudinal axis 7, with which these holders 6 are welded onto the lower side of the part of the brush body 2.
  • Figures 9 to 11 represent an embodiment whereby not only a casing in the shape of a coating is used, but also, thanks to the specific nature of the fastening of the holders 6 to the part of the brush body 2, a construction is obtained which makes it possible for the brushes 1 to be manufactured in a shorter time.
  • the holders 6 are hereby fixed to the part of the brush body 2 as these holders 6 are provided through openings 15 in this part of the brush body 2 and are welded in these openings 15, for example by means of each time two seals 16-17.
  • the holders are placed in openings 15, they are solidly anchored in the part of the brush body 2.
  • the seals 16-17 can be provided on the back side 18 of the part of the brush body 2, where there is more freedom of movement to perform welding operations, as a result of which they can also be performed by a welding robot, which is very time-saving. In practice, however, this is practically impossible in the embodiments from figures 1 to 8 .
  • the bundles of fibres 5 extend together with their coating 11, preferably only through a part of the holders 6, such that the coated bundles of fibres 5 only extend with their top ends up to a distance D under the seals, among others 16-17, with which the holders 6 are welded to the part of the brush body 2.
  • this plastic ends up in the immediate vicinity of the seals concerned, so that any melting and evaporating of plastic, and any possible development of harmful vapours during the welding is minimised or excluded.
  • Figure 12 schematically represents a number of steps of the given method which is preferably applied to realise the aforesaid brushes 1 of the invention.
  • a continuously coated fibre twine 20 is taken as a basis to form coated bundles of fibres 5, in particular a plasticised fibre twine 20, such as a plasticised twined steel cable, and pieces 21 thereof are detached at the length of the bundles of fibres 5 to be realised, in particular cut off.
  • these pieces 21, which form the bundles of fibres 5 as such, as indicated in step B, are provided with one end in a bush-shaped holder 6, after which these holders 6, as indicated in step C, are pressed together around the coated bundles of fibres 5, as a result of which the latter are fixed in the holders 6.
  • the bundles of fibres 5 fixed in the holders 6 are fixed to a part of a brush body 2 by means of the holders 6, for example welded underneath it, as in the embodiment from figures 4 to 8 , or they are for example welded in openings 15, as in the embodiment from figures 9 to 11 .
  • bundles of fibres 5 according to the invention whose casing consists of a coating 11, and not of a separate case, can also be used in other embodiments of brushes whereby the bundles of fibres 5 are for example connected to the part of the brush body 2 in another manner than by means of holders 6, or whereby the bundle of fibres 5, together with the accompanying holders 6, can be connected to the part of the brush body 2 in a detachable and replaceable manner.
  • the coating 11 has the same purpose and working principle as the known cases 9.
  • the coating 11 is also meant to keep the fibres of the bundles of fibres 5 together and to counteract their unravelling or an undesired deformation of the far ends of the bundles of fibres 5. While in use, the coating 11 will wear together with the bundles of fibres 5.
  • the material of which the coating 11 is formed must not be exclusively situated on the outside of the bundles of fibres 11.
  • the material of which the coating 11 is formed must not be exclusively situated on the outside of the bundles of fibres 11.
