Definitions

  • the present invention concerns a method for manufacturing brushes.
  • this method consists of the combination of at least four steps, namely laterally separating fibre bundles from a number of loose fibres by means of a fibre bundle remover which is provided with a recess in which fibres can be gathered when the recess passes a , fibre magazine; gradually providing the above-mentioned fibre bundles in the above-mentioned support in a mechanical manner; transferring, by means of the support, the fibre bundles provided therein to a holder by means of a mutual positioning between each respective fibre bundle and the opening in which it has to be provided, and by subsequently pushing the separate fibre bundles in the longitudinal direction in the above-mentioned openings; and fixing the fibre bundles in the brush body, or at least in a part of the brush body, by means of this holder.
  • This known method is very suitable for applying fibre bundles in a brush body, and it enables us to manufacture brushes in a simple manner in many varieties as far as thickness of the fibre bundles, colour of the fibres, etc. are concerned.
  • a disadvantage of this method is that it is not suitable for manufacturing brushes with fibres having a pointed head.
  • the method is only applied to fibres having a total length of 8 to 13 mm, whereby the pointed heads may be 4 to 8 mm long.
  • the present invention aims to remedy the above-mentioned and other disadvantages.
  • the invention concerns a method for manufacturing brushes according to the steps as claimed in claim 1.
  • An advantage of this method according to the invention is that, when fibre bundles are applied in the support, as well as when transferring the fibre bundles from the support to a holder, one always pushes in the same direction, namely on one far end of the fibres, which makes the method suitable for manufacturing brushes with sharp brush hairs.
  • FIG 1 schematically represents the method according to the invention for manufacturing brushes, whereby the method comprises the following steps:
  • the fibre bundle remover 12 is preferably some 0.5 to 2 mm thick, and the fibres 1 are 20 to 22 mm long, such that the cylindrical part of the fibres 1 is sufficiently long to hold the fibres 1.
  • the fibres 1 can for example be made of polyester or polyamide.
  • Figure 3 schematically represents how the separated fibre bundles 4 are provided in the openings 5 of the support 6 by appropriately positioning these fibre bundles 4 opposite the openings 5 concerned and by subsequently pushing these fibre bundles 4 axially in the openings 5 concerned, for example by means of a punch 14.
  • the above-mentioned punch 14 exerts its pressure force on the fibre bundles 4 at the base end 2 of the fibres 1.
  • the openings 5 in the support 6 continue from one side of the support 6 to the other side.
  • Figures 4 to 6 schematically represent an embodiment whereby a support 6 filled with fibre bundles 4 is provided up to a holder 7 by means of transfer means which are not represented in the figures, and whereby on the other side of the support 2 is provided a device 9 designed to transfer the fibre bundles 4 from the support 6 into the holder 7.
  • said device 9 consists of push-out pins 15, fixed on a common support 16 according to a pattern which corresponds to the pattern of the openings 5 in the support 6.
  • a fibre guide 17 is provided in the given example of figures 4 to 6 between the support 6 and the holder 7 which makes it possible, for example, to join certain fibre bundles 4 or to move them in a diagonal direction.
  • such a fibre guide 17 could also be used to guide the fibre bundles 4 in such a manner that they end up in the brush body 10 at a certain angle.
  • one and the same support 6 can be used for manufacturing brushes with all sorts of different fibre patterns.
  • a subsequent step F of the method then consists of connecting the fibre bundles 4 to a brush body 10.
  • fibre bundles 4 protruding from the holder with their base ends 2 in the course of a thermal treatment, by fusing them together for example, or by welding them in a base 30, as will be further discussed.
  • the fibre bundles 4 can be removed from the holder 7 to be possibly worked into a brush body 10 at a later stage, for example also by means of injection-moulding or simply by means of gluing or the like.
  • Figures 8 to 15 represent the successive steps of an alternative method according to the invention for manufacturing a brush.
  • the first steps of this alternative method are analogous to the above-described method, whereby fibre bundles 4 are separated from an amount of loose fibres 1 and are provided in the openings 5 of a support 6 by exerting a pushing force, for example by means of a punch 14, on the base ends 2 of the fibres 1.
  • a device 24 consisting of a series of push-out pins 25 provided on a support 26 whereby the tips 27 of the push-out pins 25 are aligned in relation to each other according to the above-mentioned profiling.
  • the fibre bundles 4 can be simultaneously pushed out of the first support 6 into the second support 22, whereby the fibre bundles 4 still protrude out of the second support 22 over a certain length 28 with their base ends 22, as a function of the profiling of the push-out pins 25, as is represented in figure 11 .
  • a subsequent step then consists, as is represented in figures 11 and 12 , of cutting off the parts 28 of the fibre bundles 4 protruding from the second support 22 by means of a knife 29.
  • step E whereby the fibre bundles 4 are pushed out of a support, in this case the second support 22, into a holder 7, as is represented in figures 13 to 15 .
  • the fibre bundles 4 can then be fixed to the above-mentioned base 30, for example in the course of a thermal treatment, after which the base 30 and fibre bundles 4 can be worked in a brush body 10 as a whole.
  • fibre bundles 4 it is also possible to keep the fibre bundles 4 together by forming a base in a mould by means of injection-moulding, whereby the fibre bundles are embedded in this base during the injection-moulding.
  • this base with the fibre bundles can then be worked in a brush body 10, for example also by means of injection-moulding, gluing or the like.
