Description

Detailed Description of the Invention

The present invention relates to a tweezer which is provided with a tweezer having a pinching element for holding hair growing from the skin in a continuously clamped state and pulling the hair from the skin.

A tweezer of the type described in the first paragraph is known from US Pat. No. 4,575,902. The tweezer member of this known tweezer comprises a plurality of pinching discs which are fixed to the drive shaft and a plurality of pinning discs which are fixed between auxiliary pinching discs which are arranged between the pinching discs and are connected to the pinching discs. And a pinching plate. During rotation of the pinching disc, the pinching plate is clamped against the pinching disc by shifting the auxiliary shaft. The hair present between the pinching disc and the pinching plate is thus retained and pulled out of the skin by the rotation of the pinching disc and the pinching plate.

A drawback of this known plucker is that it is painful when the hair is pulled from the skin.

The object of the present invention is to provide a plucker of the type described in the first paragraph, which considerably reduces the pain that occurs when plucking hair from the skin.

To this end, the plucking device of the present invention is characterized in that the plucking device twists the bristles around the long axis of the plucking member before the plucking member pulls the plucking hair from the skin. The point is provided with a means to make.
By the use of the means, before hair is pulled out of the skin by the hair removing member, adhesion between hair roots and hair follicles where hair already grows and hair and capillary vesicles
Achieves partial or complete destruction of the adhesion between and. In this way, a considerable reduction in the required pulling force is achieved, so that the pulling of the skin during the pulling out of the hair, which is experienced as unpleasant, is suppressed as much as possible and a considerable reduction in the pain generated. Is achieved. Furthermore, the reduction in the required pulling force achieves a considerably reduced risk of hair breakage during plucking.

[0006] A special embodiment of the tweezers according to the invention is characterized in that the required pulling force and the optimum reduction of the associated pain are achieved, characterized in that the means for twisting the hairs are the tweezers. Is to fully twist the hair around the long axis of the hair at least 5 times before pulling the hair out of the skin.

Another embodiment of the tweezers of the present invention which provides a tweezer of simple and compact construction features:
The hair removing member has the means for twisting the hair.

The tweezers have at least two pinching elements which can be displaced relative to one another from the capture position to the pinching position, in which one pinching surface of one of the pinching elements is located. Located away from the pinching surface of other pinching elements,
Another feature of the tweezers of the present invention is that in the pinching position, the pinching elements exert a pinching force on each other via the pinching surface, in that the pinching surface of the pinching element is the pinching surface. The points are slidable relative to each other in position. The sliding movement of the pinching surfaces relative to each other in the pinching position twists the bristles clamped between the pinching surfaces in a practical and efficient manner.

A disk, in which a pinching element is rotatable with respect to the housing, extends perpendicularly to the deflation opening of the housing and is displaceable relative to each other from the capture position to the pinching position. A special embodiment of the tweezers according to the invention, which is formed by a pin-shaped element of the shape, is characterized in that the disk-shaped pinching element has at least temporarily different rotational speeds while in the pinching position. It is a point. The use of different rotation speeds results in the pinching surfaces of the pinching elements sliding on each other in the pinching position, and thus
It is achieved in a simple manner that the hair present between the pinching surfaces is twisted before being pulled out.

Another feature of the tweezers of the present invention is characterized in that one of the pinching elements is rotatably supported with respect to the housing and is axially shiftable. Is fixed to the drive shaft and the other pinching element is supported so as to be freely rotatable with respect to the housing. In the case of this embodiment, in which the temporary difference between the rotational speeds of the disk-shaped pinching elements is given in a simple manner, said pinching elements are brought into the pinching position by a shift movement of the drive shaft. When the pinching element, which is freely supported with respect to the housing, is rotated by the pinching element fixed to the drive shaft, the rotational speed of the pinching element differs temporarily after reaching the pinching position.

European Patent Publication EP-A1-0,
408, 038 is a tweezer having two pinching elements, one of which is driven by an electric motor and the other of which is rotatably supported with respect to the housing of the tweezer. Please note that it is disclosed. However, the specification and drawings of this patent application do not describe the rotational speed of the pinching element on the bearing side that is rotatable with respect to the housing.

A further embodiment of the tweezers according to the invention is characterized in that the pinching element, which is rotatably supported with respect to the housing, is cup-shaped and axial. It is elastically deformable. The use of a cup-shaped and elastically deformable pinching element results in a gradual increase of the pinching force between the pinching elements after reaching the pinching position, so that they can freely rotate with respect to the housing. A gradual increase in the rotational speed of the pinching element supported on the hair is achieved and the bristles are twisted a sufficient number of times around the long axis of the bristles.

A special embodiment of the tweezers of the invention, characterized in that there is a defined speed difference between the disk-shaped pinching elements, is characterized in that one of the pinching elements is fixed to the first drive shaft. And the other pinching element is fixed to a second drive shaft arranged coaxially with the first drive shaft, one of the two drive shafts being axially shiftable, The drive shaft can be driven at different speeds.

Another feature of the tweezers of the present invention having a simple and practical construction is that the two drive shafts can be driven by only one electric motor. .

A further embodiment of the tweezers of the invention, characterized in that the pinching element is formed by a pinching disc rotatable with respect to the housing, is characterized in that the two pinching discs are non-coaxial. The point is that they have an axis of rotation and are undulated in the circumferential direction and are engaged with each other by surfaces having different numbers of undulations, so that one of the two pinching disks can be driven. In this embodiment of the tweezer, only one of the pinching discs is driven and a constant speed difference between the pinching discs is achieved, which is defined by the difference between the number of surface undulations of the two pinching discs. .

At least 5 bristles around the long axis of said bristles
A special embodiment of the tweezers of the present invention is characterized in that a sufficient speed difference between the pinching discs to achieve a sufficient twisting is achieved is characterized in that one of the two pinching discs is the other pinching disc. One more swell than that.

[0019]

The invention will be described in more detail below with reference to the accompanying drawings.

The first embodiment of the tweezer of the present invention shown in FIGS. 1 to 3 is a housing 1 having a tweezer head 5.
And a hair removing opening 3 is provided in the hair removing head 5. In the tweezer head 5, there is a tweezer member 7 capable of exposing the skin to be tipped through the tweezer opening 3.

As shown in FIG. 1, the tweezers 7 are arranged in the tweezers 7 parallel to the tweezers openings 3 and in the bearing bushes 15 and 17 of the tweezers 5 in the journal 1.
A metal drive shaft 9 with a rolling bearing having 1 and 13 is provided. Many rigid pinching discs 19 made of metal have drive shafts 9
And the drive shaft 9 so as to extend perpendicularly to the hair removal opening 3 and
It is fixed to. The tufting member 7 further includes a large number of pairs of pin-shaped discs 21a and 21b having a cup shape. These discs are made of metal, are axially flexible and are arranged between rigid pinching discs 19 and they have annular pinching surfaces 23a, 23b as shown in FIG. 2b. It is provided. As shown in detail in FIGS. 2a and 2b, each pair of pinching discs 21a, 21b is fixed to a ball bearing 25 which is common to that pair, so that the pair of pinching discs 21a, 21b is removed from the plucking head 5. It is rotatably supported in the bearing support 27.

FIG. 1 further shows that the drive shaft 9 is provided with a gear wheel 29 which is connected to an output shaft 33 of an electric motor 35 via an intermediate gear 31. Further, a guide disc 37 is fixed to the drive shaft 9 so as to engage with a guide pin 39 which is arranged obliquely with respect to the drive shaft 9 and fixed to the housing 1. By the use of the guide disc 37 and the guide pin 39, the drive shaft 9 driven by the electric motor 35 has a combined rotational and translational movement during operation, which causes the journals 11, 13 to axially bear the bearing bush 15, Slide inside 17. The amount of translational movement of the drive shaft 9 is determined by the degree of inclination of the guide shaft 37 with respect to the drive shaft 9. The width B ₁ of the gear wheel 29 shown in FIG. 1 is such that the gear wheel 29 maintains engagement with the intermediate gear 31 over the entire stroke of the drive shaft 9.

In the central part of the tweezers 7 shown in FIGS. 1 and 2a, the pinching disks 21a, 21
b does not interlock with the pinching disk 19 rotated by the electric motor 35. The hair catching slots (the catching positions of the pinching discs 19, 21a, 21b) capable of introducing the hairs existing in the tufting opening 3 are provided between the pinching discs 19 and the pinching surface 23a of the pinching discs 21a and between the pinching discs 19 and It exists between the pinching surface 23b of the disk 21b. The pinching disks 21a and 21b do not normally rotate within the capture position.

Starting from the central portion shown in FIGS. 1 and 2a, the drive shaft 9 further rotates and translates so that the pinching disc 19 becomes a pinching disc 21.
It contacts the pinching surface 23a of a. A pinching force is then created between the pinching surface 23a and the pinching disc 19 by elastic deformation of the pinching disc 21a. The difference in rotational speed between the pinching discs 19 and 21a becomes maximum at the moment when the pinching disc 19 contacts the pinching disc 21a. The difference between these rotational speeds is that the drive shaft 9 further rotates and translates, and the pinching disc 21a moves to the pinching disc 1a.
As it rotates with 9, it disappears in a short time. During a short period of time when there is a speed difference between the pinching disks 19 and 21a, the pinching disk 19 and the pinching surface 23
The bristles that lie between a and a are twisted several times around the long axis of these bristles. The hair twisting between the pinching disks 19 and 21a is shown diagrammatically in FIG. When the drive shaft 9 reaches the end of its stroke in the axial direction, the pinching disk 19 and the pinching surface 23
The pinching force with a reaches a maximum and the twisted hairs present between the pinching disc 19 and the pinching surface 23a are pulled out of the skin by the rotation of the drive shaft 9. Subsequently, the pinching disc 21a is separated from the pinching disc 19 again, and the pinching disc 21a
Is returned to the stable point in a short time due to friction in the ball bearing 25. The process described above uses the pinching disk 19
Is repeated when the pinching disk 21b is subsequently contacted.

Pinching disks 19 and 21a, 21b
It is clear from the above that hairs clamped between and are twisted around their long axis before being pulled out of the skin. By twisting the hair, the adhesion between the hair root and the hair follicle, where hair grows, is destroyed, and the adhesion between the hair and the capillary tube is partially or completely destroyed. This considerably reduces the force required to pull the hair out of the hair follicles and capillaries. On the other hand, the skin is less likely to be pulled during the pulling out of the hair, so that the pain caused by the pulling out of hair is considerably reduced. On the other hand, the risk of hair breakage during plucking (which means that the roots remain in the hair follicles and the hair continues to grow) is considerably reduced and the plucker gives good plucking results. Note that the test results show that hair twisting itself does not cause any particular pain.

Experiments have shown that the required pull-out force is substantially halved when the hairs are fully twisted at least 5 times around their long axis before being pulled out. In the case of the hair remover of the first embodiment, the number of times the hair is twisted is determined by the axial bending strength of the pinching disks 21a and 21b and the axial stroke of the pinching disk 19. When the axial bending strength of the pinching disks 21a and 21b is small, the pinching force generated in the pinching position is small,
Since the speed difference between the pinching disc 19 and the pinching discs 21a, 21b in the pinching position is maintained for a long period of time, the hairs are twisted multiple times around their long axes. It is possible to optimize the relationship between the number of times the bristles are twisted and the pinching force by a desired selection of the bending strength in the axial direction of the pinching disks 21a and 21b. In addition, by using a pinching disc that is flexible in the axial direction, it is possible to realize that the operation of the tweezers is hardly affected by the dimensional inaccuracy or the like that occurs during manufacturing of the tweezers.

In the embodiment of the tweezers shown in FIGS. 1 to 3, the tweezers 7 have means for twisting the tweezers, so that the tweezers 5 can be made compact. As will be apparent from the following description, in the case of the second embodiment of the tweezers shown in FIGS. 4 to 6, in addition to the tweezers 7, means for twisting the hair is provided.

The hair removing device shown in FIGS. 4 to 6 also has a housing 1 having a hair removing opening 3 provided in a hair removing head 5, through which the skin to be hair removed is exposed to the hair removing member 7. To do. The tweezers 7 are partially the same as the tweezers 7 of the first embodiment shown in FIGS. 1 to 3, so only the different characteristics will be explained below.

The tweezers of the second embodiment is provided with tweezers 7
In addition, the metal auxiliary is arranged parallel to the drive shaft 9 and is rotatably supported by the journals 43 and 45 in the bearing bushes 47 and 49 of the tweezer head 5 so as to be movable in the axial direction. It has a shaft 41. The auxiliary shaft 41 has an annular groove 53 provided in a plane that intersects the auxiliary shaft 41 and the drive shaft 9.
It has the guide disk 51 which has. The guide disc 51 is engaged by a groove 53 with a coupling disc 55 mounted on the drive shaft 9. This connecting disc is fixed to the drive shaft 9 so as to extend perpendicularly to the drive shaft 9, whereby the drive shaft 9 is axially connected to the auxiliary shaft 41. Furthermore, on the auxiliary shaft 41, on the one hand, the gear wheel 5 of the drive shaft 9
A gear wheel 57 is provided which is engaged with the gear wheel 9 and is connected to the output shaft 61 of the electric motor 63 on the other hand. A guide disc 65, which is arranged obliquely with respect to the output shaft 61 and is engaged with the guide disc 51 of the auxiliary shaft 41, is also fixed to the output shaft 61. Due to the use of the coupling disc 55 and the guide disc 65, the drive shaft 9 and the auxiliary shaft 41 have a combined rotational and translational movement, the translational movements being synchronized.

As shown in FIG. 4, the auxiliary shaft 41 has an auxiliary disk 67 made of synthetic rubber for each pair of pinching disks 21a, 21b.
At the center position of the tufting member 7 and the auxiliary shaft 41 shown in FIGS. 4 and 5a, each auxiliary disk 67 is in contact with the pinching disks 21a and 21b (see FIGS. 5a and 5b). ), Pinching disk 21
Rotation is given to a and 21b by an auxiliary disk 67. There is a speed difference between the pinching discs 21a, 21b and the pinching disc 19 which depends on the number of teeth of the gear wheels 57 and 59 and the diameter ratio between the disc 67 and the pinching discs 21a, 21b. It is determined.

In the central part of the drive shaft 9 and the auxiliary shaft 41 shown in FIGS. 4 and 5a, the pinching discs 19, 21a, 21b are in the catching position and the bristles present in the plucking opening 3 are of the pinching disc. It is possible to go in between. Starting from the central position, the pinching disc 19 is moved to the pinching disc 21 based on the rotation and translational movements of the drive shaft 9 and the auxiliary shaft 41.
After contacting the pinching surface 23a of a, pinching force is formed between the pinching disk 19 and the pinching surface 23a on the basis of elastic deformation of the pinching disk 21a. The width B ₂ of the auxiliary disc 67 shown in FIG. 4 is chosen such that the auxiliary disc 67 continues to hit the pinching disc 21b even at the moment when the pinching disc 19 contacts the pinching disc 21a. Therefore, the speed difference between the pinching disks 19 and 21a is maintained at that moment as well (see FIG. 6a). Auxiliary disk 67
Does not leave the pinching disc 21b until the pinching force between the pinching discs 19 and 21a is partially formed (see FIG. 6b). In this way it is achieved that the speed difference between the pinching discs 19 and 21a is maintained in the pinching position for a defined period, so that the pinching disc 19 and the pinching surface 23
The number of times the bristles clamped during a are twisted around their long axis is precisely determined. At the moment when the auxiliary disk 67 separates from the auxiliary disk 21b, the pinching disks 21a and 21b are affected by the rotation of the pinching disk 19. At this time, the pinching force reaches the maximum value and the twisted hair rotates the drive shaft 9. Is pulled out of the skin by. The auxiliary disk 67 is
Before the pinching disc 21a becomes affected by the pinching disc 19, the pinching disc 21b
Will be contacted again. The drive shaft 9 and the auxiliary shaft 41 then enter the central position again, after which the pinching disc 19 is followed by the pinching disc 21.
This operation is repeated until b is contacted.

In the case of the hair removing device of the second embodiment described above,
The number of times the bristles are twisted around their long axis is determined by the speed difference between the width B ₂ of the auxiliary disc 67 and the pinching discs 19 and 21a, 21b, so that the bristles have a long axis. The number of times twisted around can be optimized at the design stage of the tweezers by properly selecting the width B ₂ and the speed difference. Furthermore, it is clear from the above description that the means for twisting the bristles comprises an auxiliary shaft 41 with an auxiliary disc 67 in addition to the buffing member 7 of the second embodiment.

The third embodiment of the plucking device of the present invention shown in FIG. 7 is also provided with a plucking opening 3 provided in the housing 1 and the plucking head 5 of the housing 1. The skin is exposed to the plucking member 7 through the plucking opening 3, which has a first rigid metal pinching disc 69 having an annular pinching surface 71 and an axially flexible annular pinching surface 75. A second metal pinching disc 73 is provided. The first pinching disc 69 is fixed on a first metal drive shaft 77 which is rotatably supported by journals 79 and 81 in bearing bushes 83 and 85 of the tweezer head 5. The second pinching disc 73 is coaxially fixed on a second hollow metal drive shaft 87 provided on the first drive shaft 77. The second drive shaft 87 is movable in the axial direction along the first drive shaft 77 and rotatable about that axis.

The tweezer head 5 is further provided with journals 91 and 93 in bearing bushes 95 and 97 of the tweezer head 5.
It has an auxiliary shaft 89 rotatably supported by. The auxiliary shaft 89 has a first gear wheel 99 that is adjacent to each other and is engaged with the gear wheel 101 of the first drive shaft 77, and a second gear that is engaged with the gear wheel 105 of the second drive shaft 87. Wheel 10
3 and a drive pulley 107 connected to the output shaft 111 of the electric motor 113 via a belt 109. Gear wheels 99, 101, 103 and 1
The transmission ratio between 05 is between the first and second pinching discs 6
9 and 73 are configured to be driven by electric motor 113 at different rotational speeds during operation.

The guide disk 115 is obliquely arranged and fixed to the second drive shaft 87.
The guide disk 115 is engaged with a guide pin 117 fixed to the hair removing head 5. Guide disk 1
The use of 15 and the guide pin 117 causes the second drive shaft 87 to have a combined rotational and translational movement, which causes the second pinching disc 73 to move axially between the first pinching disc 69 and the capture position. Displaced, where a hair capture slot exists between the pinching discs 69 and 73 and the capture position and the pinching discs 69 and 7
3 applies a pinching force to each other via the pinching surfaces 71 and 75 on the basis of the elastic deformation of the second pinching disk 73.

In the case of the tweezers shown in FIG. 7, a constant speed difference is obtained between the pinching disks 69 and 73 during operation. Bristles that enter between the pinching surfaces 71 and 75 through the plucking openings in the catching positions of the pinching disks 69 and 73 are twisted between the pinching surfaces 71 and 75 after they reach the pinching position and twisting continues. Is pulled out of the skin while doing. Note that the speed difference between the pinching disks 69 and 73 need not be particularly large. The average hair diameter is 0.
1mm, pinching surface 7 at the pinching position
With a mutual shift of 1 and 75 of 1-2 mm, it is quite possible to twist the hairs a few times around their long axis. Pinching discs 69 and 73
A suitable speed difference between the gear wheels 99, 101, 1 is
It can be achieved in a simple way by proper choice of the transmission ratio between 03 and 105. Since the speed difference between the pinching disks 69 and 73 required for the pinching position is small, the pinching surfaces 71 and 75
The pinching surfaces 71 and 75 experience less wear during stable operation of the plucker while no hair is present between them.

In the case of the tweezers shown in FIG. 7, the constant speed difference between the pinching disks 69 and 73 is realized by driving the two pinching disks 69 and 73 at different rotational speeds. . The fourth embodiment of the tweezers according to the invention, shown in FIGS. 8 and 9, comprises two pinching discs with successively different rotational speeds, as will be clear from the description below. However, in this embodiment, only one of the two pinching discs is driven and the other pinching disc is rotated by the rotation of the driving pinching disc.

Similar to the tweezers described above, the tweezers shown in FIGS. 8 and 9 have a tweezer opening 3 provided in the tweezer head 5 of the housing 1 and include a tweezer member 7.
It has a housing 1 which allows access to it.
The tufting member 7 has a first rigid metal pinching disc 119 having a pinching surface 121 extending along the circumference of the pinching disc 119 and a pinching surface 125 extending along the circumference of the pinching disc 123. Two rigid metal pinching disks 123 are provided. The pinching disks 119 and 123 have the same diameter and the pinching surfaces 121 and 125 face each other. The first pinching disc 119 is fixed to a metal drive shaft 127 which has its rotary bearing in a bearing bush 129 of the housing 1. The drive shaft 127 is approximately 1 with respect to the plucking opening 3.
Positioned at an angle of 0 °, it is provided with a geared pulley 131 driven by an electric motor 135 which is positioned in the housing 1 via a toothed belt 133. As FIG. 8 shows, the second pinching disc 123 is mounted on a bearing shaft 137 which has its rotary bearing in a bearing bush 139 of the housing 1 and which, like the drive shaft 127, is substantially with respect to the tufting opening 3. It is positioned at an angle of 10 °. As a result, pinching disks 119 and 123 have non-coaxial rotations 141 and 143. The second pinching disc 123 is axially movable along the bearing shaft 137, and the second pinching disc 12 is attached to the bearing shaft 137.
Means 3 are provided for locking the bearing shaft 137 in the rotational direction (not shown in FIGS. 8 and 9). A spiral spring 149 is provided on the bearing shaft 137 between the flange 145 fixed to the bearing shaft 137 and the collar 147 of the second pinching disc 123. This spring presses the second pinching disc 123 against the first pinching disc 119 so that the pinching surfaces 121 and 125 exert a pinching force on each other near the plucking opening 3.

As shown in FIGS. 8 and 9, the pinching surfaces 121 and 125 have circumferentially undulating surfaces on which the pinching disks 119 and 123 engage each other under the influence of a mechanical helical spring 149. Is provided. The number of waviness of the first pinching disk 119 is 5
The number of waviness of the second pinching disk 123 is six. Due to the difference in the number of undulations between the first pinching disc 119 and the second pinching disc 123, the second pinching disc 123 is in operation
It rotates at a speed slower than 9.

As can be seen from FIGS. 8 and 9, the hair-capturing slot lies between the two pinching discs 119 and 123 over the part of the plucking opening 3, in which slot it lies. Hair can enter. Figure 9
The bristle capture slot, as shown in more detail in FIG. 3, includes a pinching surface portion 153 of the pinching disk 119 and a pinching surface portion 155 of the pinching disk 123.
Is formed by a space 151 existing between and, which is substantially parallel to the pinching surface portion 153. Starting from the position of the pinching discs 119 and 123 as shown in FIG. 9, the pinching surface portions 153 and 155 contact each other based on the rotation of the pinching discs 119 and 123 in the direction shown in FIG. This clamps the bristles present between the pinching surface portions 153 and 155 and twists them around the long axis of these bristles under the influence of the speed difference between the pinching disks 119 and 123. These hairs are then pulled out of the skin by the rotation of pinching disks 119 and 123.

In the case of the plucking device of FIGS. 8 and 9, the number of hairs twisted about their long axis is determined in particular by the number of undulations of the two pinching surfaces 121 and 125. The speed difference is created between the two pinching discs 119 and 123, which means that when the difference in the number of undulations between the two pinching surfaces 121 and 125 is 1, the hair is rotated around its long axis. Sufficient to completely twist 5 times. A further advantage of this tweezer is that it can be operated several times during one revolution of the pinching discs 119,123. This is because the parallel pinching surface portions 153 and 155 of each pair of cooperating undulations through the plucking opening 3 contribute to the plucking process.

It should be noted that the means present for twisting the bristles are incorporated in the buffing member 7 in the case of the first, third and fourth embodiments described above. However, the present invention is not limited to the tweezers in which the means for twisting the bristles is incorporated in the tweezers 7. Therefore, the second embodiment of the tweezers described above is a pinching element 19, 21.
In addition to the buffing member 7 having a and 21b, it further has means for twisting bristles (auxiliary shaft 41 having an auxiliary disk 67). In addition to this, in addition to the tweezers, the twister is provided with another twist member, and a mechanical connection for connecting the functions of the twister and the tweezers to each other is provided. It is also possible to completely separate the hair removing function. However, this generally complicates the structure of the tweezers.

The bristles are preferably twisted by the plucker at least five times completely about their long axis to achieve the appropriate reduction in pulling force required. Also note that if the hair is twisted a smaller number of times, much of the reduction in pulling force and the resulting pain has already occurred. It should be noted that if the bristles are twisted about their long axis more than four times, an increase in the pulling force of the bristles in the pulling direction is found to occur. The risk of hair breakage during pulling on the hair can be further reduced as a result of this increase.

It should also be noted that the pinching elements in the embodiments described above are formed by pinching disks. However, the present invention is not limited to tweezers having disc-shaped pinching elements, but other types of pinching elements such as those disclosed in French Patent 667,265 or disc-shaped pinching elements having windows. It also includes a tweezer provided with a cooperating pinching element. Further, the present invention may be applied to a tweezer provided with a pivotable pinching disc instead of shifting the pinching disc in the axial direction. However, in the case of this type of deplucker, one would generally have to use a more complex configuration of the pinching disc drive.

In the case of the second embodiment of the tweezers, it is also possible to use an auxiliary disc 67 which can be driven transversely to the drive shaft 9 instead of the axially offset auxiliary disc 67. Is. This can be achieved, for example, by providing the auxiliary disk 67 eccentrically with respect to the auxiliary shaft 41.

Finally, it should be noted that the tweezers according to the third and fourth embodiments each have only two pinching discs. In general, adding multiple disks axially in these tweezers is technically far from simplification. However, in the case of these tweezers, it is possible to arrange many tweezers 7 identical to each other.
