Definitions

  • the present invention concerns a method for manufacturing brushes.
  • the fibers are provided in the openings by means of a support plate with passages that are mutually arranged according to a certain pattern, whereby fiber bundles can be provided in these passages that are to be placed in a brush body.
  • fiber bundles are laterally separated from at least one amount of loose fibers, after which the fiber bundles are provided step by step in the above-mentioned support in a mechanical manner.
  • Prolonging the contact time between the stamp and the fiber bundles is particularly disadvantageous to the production capacity, whereas developing stamps with an exact profile is expensive and disadvantageous to the flexibility of the method, since a separate stamp must be made for each type of brush in this case.
  • the present invention aims to remedy the above-mentioned and other disadvantages.
  • the invention concerns a method for manufacturing brushes as defined in claim 1.
  • the present invention is advantageous in that the fiber bundles are cut at length as a function of their desired profile, according to which they have to be anchored in the holder or in the brush body, and as a function of their composition, such that, when melting the far ends of the fiber bundles, there is always an appropriate amount of fiber material in order to obtain a good melting of the far ends, such that the anchoring of the fibers in the brush body or in the holder is always of good quality.
  • the present invention also concerns a device for manufacturing brushe as defined in claim 6
  • the mutually movable pens are formed by two different sets of pens, and whereby the pens are positioned according to a different profile with their free far ends.
  • Figure 1 schematically represents a method for manufacturing brushes whereby, for the supply of fibers, use is made of a device 1 with at least one support plate 2 which is provided with openings 3 which are mutually arranged according to a specific pattern, whereby fiber bundles 4 can be collected in this support 2 that need to be provided in a brush body 5.
  • This method further mainly consists of the combination of at least four operational steps, a first step 6 in which the fiber bundles 4 are separated from at least one amount of loose fibers 7; a second step 8 which consists in filling the support 2 with fiber bundles 4; a third step 9 which consists in transmitting the fiber bundles 4 provided in said support plate to a holder 10 by means of the support 2; and a fourth step respectively, in which the fiber bundles 4 are fixed in the brush body 5 or a part thereof by means of the holder 10.
  • Figures 2 to 6 represent a part of the device 1 in greater detail which makes it possible to transfer the fiber bundles 4 to the holder 10.
  • this part of the device 1 contains the above-mentioned support 2 and the transmission means 11.
  • the support 2 is preferably composed of an actual support 12 and a guiding plate 13 for fibers.
  • the guiding plate 13 for fibers is provided with openings 14 which are arranged according to a pattern on one side which corresponds to the pattern of the openings 3 in the actual support 12, whereas the same openings are arranged according to a pattern on the other side of the guiding plate 13 which corresponds to the pattern in which the fiber bundles 4 must be fixed in the brush body 5.
  • the transmission means 11 in this case consist of a base 15 and a guiding plate 16 in which are provided different passages 17, 18 which are arranged according to a pattern that corresponds to the openings 3 in the actual support 2.
  • each of the passages 17 in the base is provided a pen 19 which can be axially moved in the passage 18 concerned of the guiding plate 16.
  • At least one of the above-mentioned pens 19 can be moved in the base according to an axial translation, or at least one of the pens 19 has a variable length, and the device comprises means which are not represented in the figures which make it possible to accurately check the position of the pens 19.
  • the aforesaid part of the device preferably contains a knife 20 which, when operational, can move over the side wall of the guiding plate 13 for fibers that is directed away from the actual support, as well as means which make it possible to make the material out of which the fibers are made melt.
  • these heating means consist of a stamp 22 in a heat-conducting material which is electrically heated.
  • the guiding plate 13 for fibers is placed against the actual support 12 filled with fiber bundles 4, while the pens 19 are being positioned according to a desired intermediary profile.
  • profile is meant here the mutual position of the fiber bundles in an axial direction, whereby the desired profile is the position of the fiber bundles 4 after they have been fixed in the holder of the brush body 5.
  • the intermediary profile and the desired profile are preferably different.
  • This intermediary profile depends on the desired profile in which the fiber bundles 4 must be provided in the brush body 5, and it is designed to obtain a relatively uniform distribution of fiber material on the side of the holder 10 or the brush body 5 where the far ends of the fiber bundles are melted so as to anchor the fiber bundles 4 in the holder 10 or the brush body 5.
  • the intermediary profile is such that the fiber bundle with the largest number of fibers will be pushed further out of the support 2 in case the pens 19 have an intermediary profile.
  • the holder 10 is positioned against the guiding plate 13 for fibers, whereby the openings 14 in the guiding plate 13 are situated opposite openings 21 in the holder 10.
  • one or several of the pens 19 are axially moved in relation to each other in the base 15, until these pens 19 are situated in the desired profile in which the fiber bundles 4 must be provided in the brush body 5, after which the basis 15 of the transmission means 11 is moved over a certain distance towards the support 2, such that the fiber bundles 4 are pushed over a desired distance through the openings 21 in the holder 10.
  • the far ends of the fiber bundles 4, which protrude through the openings 21 in the holder 10, are heated by means of the stamp 22 or the like, such that the above-mentioned far ends melt together and thus, after having solidified again, form an anchoring for the fiber bundles 4.
  • the holder 10 can be fixed in the known manner in the brush body or in a part thereof.
  • the far ends of the fibers must not necessarily be cut off on one side of the guiding plate 13 for fibers, but that they can just as well be cut off on the surface of the actual support 12 against which the guiding plate 13 for fibers is provided, or that the shortening can take place when the fiber bundles 4 have been provided in the holder 10 according to the intermediary profile.
  • the fibers must not necessarily be anchored in a holder 10 either, but that they can be anchored just as well directly in the brush body 5.
