    The invention relates to a single-row straight brush comprising tufts of pressed bristles or inserted into tufts of a brush body.
    Tufts of individual bristles arranged in rows next to one another form the bristle area in straight brushes in the known manufacturing process, the pressing method also known as the bunching process. The tufts of bristles are pressed / inserted into pre-drilled blind holes and are anchored to the bottom of the blind hole bore with a wire loop or metal anchor. Since there must always be a technically required gap between the different forests for tufts, there are also visible gaps where the tufts of hair leave the body. These visible gaps between the tufts of hair close at the earliest at about 5 mm - 10 mm above the body due to the "growth" conic tufts of hair. If, for the end use, a completely opaque straight brush is necessary, at least one second row of tufts offset on the interstices should be inserted next to the first row of tufts to cover the intermediate spaces of the first row.
    Another known possibility is that as a brush body, for example, an extruded plastic profile with a lip of a height of about 10 mm is used to cover the interspaces between the tufts of bristles in the body. case of a stacking on a row.
    The problem underlying the invention is that in the case of single-row straight brushes, an opaque bristle area must be produced solely by the tufts of bristles by the pressing / bunching process.
    The solution to the problem according to the invention is that the brush body has a groove extending in the longitudinal direction of the brush body, connecting the bores for tufts or connecting to the tine introduction ends of the bores. for tufts.
    This groove extends in the region of the body surface centrally symmetrically through the tuft holes or is connected thereto, whereby the bristle material already widens laterally into the interior of the body. outer contour of the brush body and that the bristle material can get closer between the different tufts, so that an opaque bristle area without gap is formed outside the outer contour of the brush body.
    The groove may for example have in this case a width of about 30% to about 60% of the diameter of the tuft holes. The depth of the groove may be, for example, about 30% to about 50% of the tuft depth. The depth of tufa boring is usually twice the diameter of the boreholes. The width and depth of the groove are also a function of the pile material used and the diameter of the pile.
    It may be appropriate for the tuft holes to have an enlarged cross-sectional portion in the region of their insertion ends. As a result, the tufts of bristles may already expand somewhat in the enlarged cross-sectional area of the tufts, so that the height of the groove in which the remaining enlargement takes place to the overlap without gaps tufts of hair can be reduced.
    In this case, the tuft holes may have a stepped cross-sectional change.
    Alternatively, the tuft holes may have a conically tapering portion from the tuft insertion end toward the bottom of the tuft drill holes.
    The straight brush may have a brush body manufactured by an extrusion process. This allows the manufacture of straight brushes of any length or even straight brush strips having several meters long, a segment can be cut to length whenever desired.
    In this case, it is appropriate that the brush body provided with the groove is manufactured by the extrusion process. Because the groove is already formed during extrusion, no other operation with corresponding devices is required to introduce the groove into the brush body.
    Alternatively, the brush body may have a groove introduced by milling or by thermoplastic deformation.
    The groove may have a rectangular cross section or a rounded cross section at least in the region of the bottom of the groove.
    The invention also relates to a device for making a straight brush, comprising a drilling unit for drilling tufts and a pressing unit for pressing or inserting tufts of hair into tufts.
    The device according to the invention is characterized in that an extruder is provided to form the brush body provided with the groove. This allows the manufacture of the brush body without additional device to introduce the groove.
    An alternative embodiment provides that a unit is provided for introducing the groove into the brush body.
    In this case, the unit may be a milling unit or be designed to thermoplastically insert the groove into the brush body.
    The usual production speed is fully maintained with an additional milling unit between the drilling unit and the pressing unit. No additional material is needed for the product. A small portion of the usual amount of pile material is pressed into the groove within the brush body during the pressing operation, so that a continuous, fully opaque bristle area is formed from the upper edge of the brush body. Existing extrusion body profiles can also be used without change for this opaque stacking.
    To avoid in high-speed automatic stacking machines that, when drilling tufts holes in a brush body already provided with a groove, chips remain in the groove, it can be expected in the region of l Drilling unit of the doctor blades which are placed next to the piercing tool and along which the drilling chips can slide out of the groove outwards.
    The advantages obtained with the invention consist in particular in that it is possible to manufacture straight row brushes which are absolutely opaque by the pressing process / bunching process. Considerable savings in production costs and material costs can thus be obtained. A second row of tufts or a sealing lip in the brush body is not necessary.
    Exemplary embodiments of the invention are shown in the accompanying drawings and are described in more detail below.
    It is shown in fig. 1 a schematic structure of a conventional straight brush according to the state of the art, FIG. 2 a schematic structure of an opaque straight brush according to the invention, FIG. 3 is a perspective view of a brush body with a groove, FIG. 4 a schematic structure of a device for making a straight brush, FIG. A schematic longitudinal section of a brush body during drilling of tufts forcing, FIG. 6 a front sectional representation of the arrangement according to Figure 5, fig. 7 is a perspective view of a brush body with simple tuft holes, FIG. 8 the partially emptied brush body according to Figure 7 in a sectional representation, FIG. 9 is a perspective view of a brush body with stepped transverse sectional changes in the tuft holes, lafig. 10 the brush body partly empoilé according to Figure 9 in a sectional representation, lafig. 11 is a perspective view of a brush body with tufa bores having conically tapered portions of the tine introduction end toward the bottom of the tufa bores; and FIG. 12 the brush body partly empoilé according to Figure 11 in a sectional representation.
    Figure 1 shows in the upper part the section through a conventional straight row brush 11a as part of the pressing process / bunching process according to the state of the art. The gap marked by the circle 1 between the tufts of bristles 3 shows the region of non-opacity of the fiber zone. The brush body 2 is provided with tuft holes 4 of the blind hole type in which the tufts of bristles 3 are pressed.
    In the lower part of Figure 1, the brush body 2 and the tuft holes are shown in section and in view from above.
    Figure 2 shows in the upper section through a straight brush 11 according to the invention, produced with a groove 5, as part of the pressing process / bunching process.
    After drilling the tufted holes 4 of the terminal hole type, the groove 5 is inserted into the brush body 5 before the tufts of bristles 3 are pressed or inserted. The tufts of bristles 3 already rest in the groove 5 inside the brush body 2, so that a zone of bristles is formed in the opaque assembly and without gaps outside the brush body 2 .
    In the lower part of FIG. 2, the section through the brush body shows on the left the tufted holes 4 of the terminal-hole type with groove 5 and the groove radius 6 possible. Instead of the rounded contour, the groove 5 could also have a rectangular cross section. On the right, Figure 2 shows a top view of the brush body 2 with the groove 5 connecting the tuft holes 4 of the blind hole type.
    FIG. 3 shows a perspective representation of the brush body 2 with the groove 5 connecting the tufted holes 4 of the blind hole type.
    FIG. 4 shows the schematic structure of an automatic device 12, completed, according to the invention, by a milling unit 8, for the manufacture of a straight brush 11.
    The brush body 2 is progressively conveyed in the direction of the arrow 10 through the device 12. In this case, the brush body 2 passes first in front of the drilling unit 7 which drills the burr holes 4 terminal hole type. Subsequently, the brush body 2 with the already drilled turret bores 4 passes through the milling unit 8 which produces the groove 5. At the end of the process, the tufts of bristles 3 are pressed / inserted into the tufts bores 4 in the pressing unit 9.
    Figures 5 and 6 respectively show a brush body 2 when drilling tufts holes 4 with a drilling unit 7. The brush body 2 is already provided with a groove 5 before drilling. The brush body 2 can be made in particular by an extrusion process in which the groove 5 is directly formed at the same time so that a separate operation to introduce the groove 5 is not necessary.
    Next to the drill 13 of the drilling unit 7 are provided two scrapers 14 along which unrepresented drilling chips can slide and can be transported out of the groove outwards to prevent clogging of the groove 5 with drilling chips.
    Figure 7 shows the brush body 2 completely drilled, and Figure 8 shows the brush body 2 partially stacked in sectional representation.
    In the brush body according to Figs. 9 and 10, the tuft holes 4 respectively have a stepped cross-sectional change. The tufts of bristles 3 can in this case, as can clearly be seen in FIG. 10, already widen in the enlarged portion 15a of the tufts 4 so that the groove 5 can have a reduced height relative to the embodiment according to Figures 7 and 8.
    The same is true for the embodiment according to FIGS. 11 and 12 in which the tuft holes 4 respectively have a part 15b tapered in a tapered manner from the tuft insertion end towards the bottom of the drillings for tufts.
    In all the exemplary embodiments shown, the free edge of the brush body 2 which is formed by the upper edge of the groove 5 is each time above the tuft of bristles 3 adjacent to the intersection point so that a row of closed opaque tufts is obtained.
    The problem underlying the invention is to close the usual interstices between tufts of straight brush bristles to a row (packed) to obtain an opaque area of hair.
    This problem is solved by a groove connecting the tuft holes of the brush body. In this groove, the pile material can already deviate to the side of immediately adjacent tufts of bristles within the brush body. As a result, no gap between the tufts of bristles is visible from the body surface and the bristle area is opaque continuously.
    Such opaque straight brushes find use in many sealing functions in industry where it is necessary to seal in a flexible manner, for example to chips, dust, water spray or the incidence of light.
