Device for producing bundles of hair or bristles (Dolls) from a hair or bristle band

The innovation relates to a device for producing Hair or bristle bundles (dolls) from a hair or bristle collar, with a perforated plate, in which the collar with the end on the root side and divided into a number of pupae corresponding to the number of holes, after which the root end of each pupa is solidified with a binder.

One such device is from US Pat. No. 3,136,582 previously known. In this case, after a support plate has been pulled away from the side, the bristles fall in the free pail onto a perforated plate and distribute themselves thanks to the wedge-shaped tapering upwards

Walls on the individual holes, in which the liquid ^! Synthetic resin is introduced. After solidification, the ι

ι puppets pulled out of the individual holes, which is why the | Perforated plate made of flexible material, in particular plastic.

As with this free fall device for dividing the federal government in pupae and for dipping the root ends into the liquid glue, only one's own gravity is available, this device is limited to relatively heavy bristles, but it fails with hair, especially during manufacture of dolls for fine hair brushes. Also could jbine desired contour of the pupae can only be achieved later mechanically by cutting, but with the valuable tips would be cut off and incurred as waste η.

Fine-hair brushes, on the other hand, are made by the brush maker in the grandfather-style Made by hand: the brush maker takes a bundle of hair from a hair band and compresses it a shaped sleeve with a correspondingly curved base in the desired contour and sets the hair bundle formed in this way the brush clamp, in which the hair bundle is held by gluing and clamping. Of course they are up this way, awkwardly hand-made fine-hair brushes are very expensive.

In contrast, the innovation is based on the task of creating a device of the type specified at the beginning, with which

a large number of hair or bristle bundles or dolls are to be produced at the same time. The aim is to divide the bundle into a number of bundles of hair or bristles, which are then shaped without damage and solidified on the root side with binding agent, so that they can then be ejected as finished brush puppets. In this way, hair dolls in particular, but also those that are easier to manufacture, should be ■? en bristle dolls can be produced cheaply in large numbers with relatively simple aids.

The solution to this problem is essentially that a continuously perforated perforated plate, on one of which at te (flag side) the walls between the holes each end in a vertex line with the flag side vertically guided downwards in relation to a hair or bristle collar holder into the root end of the collar can be lowered is, which waistband holder is provided with a horizontal bottom for resting the tips of the hair or bristles of the waistband is and can be brought into operative connection with an ultrasonic transmitter or vibration transmitter.

Instead of its own gravity with the previously known freefall device According to the innovation, ultrasound or vibrations will be used to split the bundle into bundles upon penetration applied in the perforated plate. In doing so, you are not limited to the bristles' own gravity, but rather you can adjust the intensity of the vibrations to the desired level. The structure or the

the structure of the hair and bristles is of great importance. ¹ uie hair is namely not smooth, but from single-Ib. Rc h / n th it: ipanmengesetzt and instruct err circumferential Un likewise; .- 'th, at particular barb-like approaches. Hiedruch 'is the friction between the individual hair relatively large, so that it is also relatively large simply acting resist mechanical forces.

Under the action of the ultrasound or the oohwichtungeii or vibrations according to the innovation, the federal government will be proportionate slightly pushed into the perforated plate =

namely / preferably with the new tion sgemä ssen device the hair is not applied from top to bottom r for the! perforated plate, rather, conversely, the perforated plate with its through holes is lowered from above onto the belt, with the bunch of hair on the bottom of the BundLalter rests on and vibrates or is ultrasound from there. The perforated plate is guided vertically and can freely lower itself under its own weight set accordingly.

The inner side wall of the collar holder is advantageous accordingly the conicity or i'orm of the hair to segregate the opening edge expanded towards. The individual IlaararLen, such as weasel, Marten and foal hair each have a characteristic, essentially conical shape, that is to say, a Haaibund conically tapered from the root to the edge or tip.

The fret holder expands accordingly on its bottom! the hair ends of the Federation to rest his Öffnungsra'ad 'out *

Furthermore, the side wall of the holder m * t runs axially, the grooves, grooves or grooves, whereby the adjacent hairs are guided axially and in turn those further inward Hair half in axial position.

Fachdem now. the federal government with the device according to the innovation in

If a large number of bundles is divided up, the individual bundles could now be further processed in a conventional manner; It is of great advantage, however, that the bundles remain in the perforated plate, can, in a further development of the innovation, be given a vriinschleine contour and can then be solidified on the root side with iodine. Only then, when ready ^| uppen ^J they are ejected from the perforated plate "For this purpose is first proposed that the perforated plate is lowered with its root side to a mold pin plate on which the holes are arranged according to Porinstifte, sized free, upper ends of the desired The contour of the brush puppets has been reshaped, which form pin plate? is also in operative connection with an ultrasound or vibration transmitter. Under the influence of the ultrasound, the individual hairs of each doll can be shifted relatively easily in relation to one another, so when inserting the Eorxiis pins into the holes of the perforated plate, i.e. into the worm

Zelenden of the dolls the corresponding shape is reshaped at the tip or flag side. Under lighter working conditions one could do without the ultrasound.

The shaped pins are expediently roughened, grooved or stepped, to prevent the hair from sliding sideways.

It is also advantageous to have an upper guide plate a large number of pointed mandrel o can be lowered onto the hair band.

In order to be able to fix or solidify the shaped dolls with the same device, in particular by means of the perforated plate, is According to the innovation it is further proposed that a heatable plate with a horizontal top side for receiving a liquefied Binder layer (adhesive plate) is provided, opposite which the perforated plate with the root side ahead is lowerable. This lowering preferably takes place in two stages: First so far that the root side meets the upper side the adhesive layer touches »The adhesive now penetrates due to capillary force into the root ends of the pupae, so that the Dolls are fixed or solidified in the desired shape after the solidification or hardening of the binding agent. After this The perforated plate can then be lowered down to the top of the adhesive plate, with the remaining binder up to squeezed sideways onto a thin film.

According to the innovation, an ejector plate is also provided, on which according to the perforated plate ejector pins are arranged, which are staggered in length in such a way that the dolls are not all at the same time, but in groups are ejected one after the other. Duron this lateral staggering of the ejection process, even very large perforated plates can be freed from the solidified pupae without the permissible load is exceeded.

Schliesslinh also suggests that a correspondingly perforated scraper plate rests on the ejector plate so that it can be removed. The adhesive film remaining under the perforated plate during the gluing process has the tendency to get between the ejectors when it is ejected. pin on the ejector plate. These individual i'ilme would quickly build up into a thick layer, which would gradually render the pens ineffective. Using the stripper plate, the \

PiIm simply stripped from the ejector plate or the pins will.

Finally, it is suggested that it be vertical two or more workstations offset at an angle for consecutive Work processes are provided, which can be stepped from one workstation to another according to Üevolverart are * In this way, the entire manufacturing process with its various kind of steps can be automated. There the hair or dolls remain in the perforated plate during the entire manufacturing process, the automatic

matic device relatively simple.

i'ig. 7 shows a schematic plan view of a revolver switchable Device according to the innovation with four work stations.

In the device according to FIG. 1, the hair band 1 is introduced into a perforated plate 3 with the root end 2 first and thereby divided into a corresponding number of hair bundles; during the further processing operations, namely the shaping in the

ι device according to Fig. 3 or> \, solidification in the pre \ direction in FIG. 3, the hair bundles remain in the orifice plate, "until finally by the apparatus according to Fig. 6 are ejected ais final formed and solidified dolls.

At the beginning, the hair bundle 1 to be processed is first entered into the bundle holder 4. The collar holder 4 has essentially the shape of a cup with upwardly tapering Wanaungi and a circumferential flange on the underside or on the bottom. The inner wall 5 widens up to the opening edge; with a conicity corresponding to the shape of the hair. For lateral guidance of the hair, grooves are provided on the inner wall 5. This collar holder 4 is inserted into a recess in a support plate 6. The support plate 6 with the collar holder 4 can be lowered along vertical guide pins 7 against spring pressure 8. In the lowered position, the support plate 6 comes into contact with ultrasound transmitters or sonotrodes 9 of an ultrasound generator 10 kept in contact with the sonotrodes 9.

Likewise guided vertically by the guide pins 7 by means of the bores 14, the perforated plate is lowered and placed on the upper side, that is, the root side of the hair bundle 1. The individual holes 16 of the perforated plate 3 go through the entire thickness by and extend to the bottom in Fig. 1

Page (hereinafter flag page). The correspondingly thinning Walls between the individual holes do not end in sharp edges, but are rounded, run thus in apex lines surrounding a hole each. To this In a funnel-shaped manner, the hair is guided into the individual holes. In particular, the hair is not split And split hairs are not torn open any further, but are either divided into one or the other two adjacent holes. A circumferential funnel 17 is used for lateral guidance of the hair band 1.

The perforated plate 3, which is equipped with bundles of hair in FIG. 1, is turned over by 180 ° and inserted into the shaping device according to FIG. 3. The perforated plate 3 is thus with the root side pointing upward in FIG. 1 downwards onto a pin plate 20 lowered. The pin plate 20 is provided with pins 21 corresponding to the perforated plate 3, a free upper end is shaped according to the contour of the dolls.

When the perforated plate 3 is placed on the shaped pin plate 20 penetrates a form pin 21 each into a hole 15, the

j individual hair bundles are brought into the appropriate shape.

This deformation now also takes place under action of ultrasound. For this purpose, the shaped pin plate 20 is in turn inserted into a base plate 22, which compared to the ultrasonic transducers 23 of an ultrasonic generator 24 can be lowered, similar to FIG. 1, by means of pins 25

vertically guided against spring pressure 26. The ultrasonic generator is from a cover 2? surround. The perforated plate is in turn guided vertically with its guide holes 14 on the Guide pin 2 ^, which is also used to guide a upper guide plate 28 are used. The upper guide plate 28 has a large number of pins on its underside, which penetrate into the hair band when the guide plate 28 is lowered and guide the individual hairs to the side. Fig. 4 shows four different shaped pins 21a, b, c, d for different brush shapes. It is important that the formative Tip of the pins 21 is not smooth, but roughened with grooves or is provided or graduated. This roughened upper side is denoted by 29 in FIG. 4. It becomes a Slipping of the hair downwards or to the oeite avoided.

The perforated plate 3 is now again entered with the root side down into the device according to FIG. 5 in order to solidify the hair bundles formed according to FIG. 3 with binding agent on their root side. For this purpose, an adhesive plate 30 with a flat, horizontal surface 31 is provided. This upper side 31 is sunk into the plate 30 in FIG. 5 in order to obtain a rotating hand 32, which, however, is not inevitable. Liquid resin is applied in a thin layer 33 to the flat upper side 31. The desired viscosity of the binder layer 33 is set by means of a heating device 34. The orifice plate 3 is now \ lowered onto the binder layer 33 such that their

Due to the Kapillarkrt-ft now J he eingesaugt- liquid adhesive in d \ e root sides of the hollows The remaining The remaining adhesive is squeezed off by completely lowering the perforated plate 3 to the side "

After sufficient stabilization, the pupae are removed from the individual holes 15 of the perforated plate 3 by means of the device after i'ig. 6 ejected. To this end is on a solid. Base plate 35 is an ejector plate 36 placed on the their top with the holes corresponding Aussoosüorstifte 37 is provided. It is essential that the ejector pins 37 are not all of the same length, but are staggered in length in groups.

When lowering the hotplate 3, the longest come first and then one after the other shorter ejector pins in action, so that the groups are ejected accordingly. Through this division of the ejection process in groups one after the other, the required Krai'u limited to the permissible level.

How finally I) ¹ Ig. 7 schematically shows, individual workstations can be arranged at an angular offset around a vertical rotating column. A vertical column 39 is mounted on a corresponding machine frame or table 38, around which a

Slewing ring 40 with four arms 41 is rotatable. At the end of each arm 41, a work station or a holder for a perforated plate 3 is provided. This turntable with arms 41 can then be advanced from one work station to the next. For example, in the station 42 a perforated plate 3 ^m i 't a fresh hair collar is charged. In the' next following station 43 a hair collar is in each case formed by means of a mold apparatus according to FIG. 3. In the now folgen4 the workstation 44 is in each case a perforated plate 3 ^m ^^ The hair bundles previously formed in the station are cast and solidified with binding agent according to the device according to Fig. 5. At the next station 45, the solidified dolls are ejected from the perforated plate with a device according to 1'ig.
