The present invention relates to an apparatus and a method for applying an unfoldable

Adhesive frame, each of which is a reliable,

reproducible and material-saving formation of a dust-tight seal on an object. The invention further relates to an adhesive frame, which by means of such a device and such a method

is processable. The invention further relates to a system with an object and an adhesive frame arranged thereon.

Adhesive frames are used, among other things, around a

To seal the interior of an object against the ingress of dust. For example, adhesive-capable individual parts can be put together manually to form an adhesive frame. It is a challenge to precisely form a given position on an object and also a reliable one

Sealing also in corner areas of the adhesive frame

to provide.

It is an object on which the invention is based, in a simple and inexpensive manner, a precise,

To enable reproducible and material-saving formation of a dust-tight seal on an object.

The task is characterized by the characteristics of the independent

Claims resolved. Advantageous further developments are specified in the subclaims.

According to one aspect of the invention, a device for applying an adhesive frame comprises a foldable frame holder for holding the adhesive frame with a plurality of

Frame elements which are designed and coupled to one another in such a way that the frame holder can be transferred between a folded-in, first state and an opened-up, second state with a predetermined frame geometry by means of opening and folding about a folding axis. The

The device further comprises an object holder for receiving an object, which is pivotally coupled to the frame holder, so that the object holder relative to the frame holder by means of pivoting about a pivot axis between an open, first state and one

closed, second state is transferable. Means

Forming the second state of the frame holder, the positioned adhesive frame can be unfolded, and by forming the second state of the object holder, it is at a predetermined position on a surface of the

Applicable object.

By means of the device described is a

Application tool realizable, that on simple and

cost-effective way a precise and reproducible

Application of a foldable adhesive frame and thereby a precise and material-saving formation of a dustproof seal on an object enables. Such an application device enables opening and dispensing of a folded stamped part that is adhesive on both sides in the form of an adhesive frame.

Such an adhesive frame has, for example, an adhesive foam material and is covered on the underside and on the top with a protective layer. The adhesive frame has a plurality of elements that realize a folded adhesive frame in a first orientation. By unfolding the elements, a second one

State of the adhesive frame are formed, in which it is self-contained and has, for example, a square basic shape.

Such a device can be used with the device described

Adhesive frame as a coherent part geometry

can be applied to a desired position of an object with little effort and time. In this way, an inexpensive and reliable manufacture of a

Be contributed product, which comprises such an object applied with an adhesive frame. For example, the object to be sealed is a display glass pane which, when used in a multimedia device, enables reliable and positionally accurate dust sealing.

The use of fold-out or unfoldable

Adhesive frame can particularly affect one

Benefit material consumption. Compared to an adhesive die-cut frame that is punched as a whole, which, for example, results in a high level of material waste, material can be used with unfoldable

Adhesive frame can be reduced by 80 or 90%, for example. Compared to an adhesive frame composed of individual parts, the application of individual strips is time-consuming and generally does not enable a reliable dust-tight connection of the corners of the individual parts to one another.

By means of the device, folded adhesive frames can be reliably and gently stretched and attached to an object at a predetermined position in a precise and reproducible manner, so that a time and material-saving formation of a dust seal on the object and an associated product can be contributed.

For this purpose, the frame holder comprises a first folding mechanism, for example in the form of

Hinge elements, by means of which the individual

Frame elements can be spanned into a frame. In the first, folded-in state, the frame elements are aligned to receive the folded adhesive frame. By folding out the frame elements, the inserted adhesive frame is unfolded in a controlled manner. The

Frame elements are corresponding to the geometry of the

Adhesive frame designed to match, so that they essentially simulate the geometry of the folded adhesive frame in the folded state and the geometry of the unfolded adhesive frame in the unfolded state.

Unfolding the frame bracket from the first,

folded state in the second, unfolded state takes place by means of a movement about the folding axis, which is a rotary, pivoting and / or translational movement of individual

Includes frame elements. The folding axis represents an effective axis with respect to which individual ones

Move the frame elements when opening the frame bracket. If the frame elements are coupled to one another by means of hinge elements, the respective hinge elements have an associated axis of rotation about which the corresponding one

Frame element when forming the second state of the

Frame bracket is rotated. Unfolding the

The frame is mounted essentially in a plane perpendicular to the folding axis or the axes of rotation of the

Hinge elements. An inverse sequence of movements enables folding the frame elements and forming the first state of the frame holder. The frame holder can thus be reversibly extended and retracted and therefore enables the adhesive frame to be dispensed continuously.

The object holder has corresponding properties.

To switch between the first and second state, the object holder comprises a swivel mechanism which represents a second folding mechanism. The object holder is so, for example, by means of a hinge element

stored that they up and around the pivot axis

can be closed. To hold an object, the object holder preferably has one or more holding elements which hold the object reliably and securely in a predetermined position relative to the frame holder. Alternatively or additionally, the

Frame holder have a swivel mechanism in order to be able to be moved in the direction of the object holder. The frame bracket and the

Object holder moves relatively towards each other and a precise and repeatable positioning of the object over, under or next to the unfolded adhesive frame is made possible.

According to a preferred development of the device, the frame holder has at least one fixing element which is designed to fix the adhesive frame to be applied in a predetermined position on the frame holder. A respective frame element preferably has at least one fixing element in order to ensure a particularly secure hold of the adhesive frame to be glued. The respective fixing element comprises, for example, an opening which extends through the respective frame element and which is fluidly coupled to a suction connection, so that the adhesive frame to be applied can be fixed in a predetermined position on the frame holder by means of a negative pressure provided by the suction connection. For this purpose, the device can comprise a vacuum pump which, connected to the suction opening, sets a predetermined negative pressure in the respective frame element, so that the adhesive frame placed on the frame holder is sucked in and thereby in its position

is reliably fixed. Everyone is preferred

Frame element assigned an intake opening, which the

Setting up a suction vacuum allows.

According to a particularly preferred development, the respective fixing element each has a recess which adjoins a respective opening in order for a

Suction force to provide an increase in the attack surface in relation to the adhesive frame. Such a recess is for example in the form of a milled pocket on one

Top of the respective frame element is formed, which is provided for receiving the adhesive frame. The recess can be designed as a long channel or slot. However, several recesses can also be provided on a respective frame element, each of which has one

suction opening is allocated. The frame holder preferably has at least one for each frame element

Fixing element with a separate vacuum supply.

According to a further development of the device, a respective frame element has a guide groove for receiving the adhesive frame to be applied. Such a guide groove enables easy and reliable positioning of the adhesive frame in or on the frame holder. A depth of the respective guide groove is useful and is designed to match the thickness of the adhesive frame to be applied.

In this way, a certain amount of supernatant is on the

Given frame elements placed on the adhesive frame, so that when applying the adhesive frame, the object can be reliably brought into contact with the adhesive frame.

According to a development of the device, the

Frame holder have a positioning element which is designed to position the adhesive frame to be applied in a predetermined manner relative to the frame holder. Such a positioning element is implemented, for example, as a dowel pin, which fits into a recess provided in the

Adhesive frame is insertable to allow easy alignment of the adhesive frame on the frame bracket. In this way, indexing of the collapsed

Adhesive frame take place before it is inserted into the guide grooves of the respective frame elements. This makes positioning particularly reliable and reliable

For example, the frame bracket can be three or four

Have frame elements which are designed to be pivotable or to be opened and closed. Apart from a folding mechanism by means of hinge elements, the

Also allow the device to be opened and closed by means of a scissor mechanism. In addition, the device or the frame holder can have five, six or more frame elements in order to specify an associated frame geometry and corresponding adhesive frames to unfold and apply reliably and precisely.

According to a further development, the device has an actuating element which is designed to operate the

To transfer frame bracket between the first state and the second state. The actuator is

for example as a pin-shaped projection on one

Frame element formed, which enables easy pulling out and pressing in of the frame holder. Such opening and closing can be done manually or can be realized by means of a corresponding drive. In addition, folding or swiveling the

Object holder can be carried out manually or automatically by means of an actuating element in order to switch between the first and the second state.

Providing, inserting and fixing the adhesive frame, pulling off existing protective layers, opening the frame holder and unfolding the adhesive frame, inserting and positioning an object in the

Object holder, swiveling, closing and pressing the object holder can be done manually, partially automated or fully automated, for example by means of robots and / or corresponding mechanical drives. The device then preferably comprises a control unit which carries out the individual steps for applying the

Checked adhesive frame on an object.

For example, vacuum control can also be used to fix the adhesive frame to the frame holder by means of a

electronic control. Adhesive frames can be provided in the form of stamped parts, for example as a material web with a variety of adhesive frames,

are automatically fed to the frame holder. In doing so, individual adhesive frames can be laid along predetermined

Perforations are separated from each other and / or the

The device further comprises a cutting unit, which makes it possible to separate a leading adhesive frame from a subsequent one. If, for example, the adhesive frame is placed upside down in the frame holder, an automated removal of a base liner, which is a

Protective layer forms for example on an adhesive bottom of the adhesive frame, done automatically. In addition, application of the adhesive frame to the object, for example a display, a housing or a lid, can also be carried out automatically.

According to a preferred development, the device comprises a pressing mechanism, which is designed to provide a predetermined one in the second state of the frame holder and the second state of the object holder

Exercise frame bracket. In this way, a

reliable pressing or contacting of the adhesive frame to be applied and the object can be realized. Such pressing can be done manually, for example, by applying pressure along the object or

Object holder in the direction of the unfolded

Adhesive frame done. Alternatively or additionally, the device can comprise a stamp element which is attached to the

The geometry of the unfolded adhesive frame and / or the opened frame holder is adapted, for example, to enable automated pressure application. Furthermore, an automated detachment of a covering liner can be provided, which for example according to the previous one

Alignment of the adhesive frame described forms a protective layer on an adhesive top of the adhesive frame, are performed. In addition, the device can be further configured to enable further processing of the object provided with the adhesive frame. For example, the object can be attached manually or automatically to another component with the adhesive frame in order to form an end product or part end product.

The device described enables a reproducible, positionally accurate and effortless application of a

unfoldable adhesive frame on an object and thereby forming a dustproof frame with closed corners, which enables a geometrically precise alignment and also makes a contribution to material and cost savings in comparison to completely punched adhesive geometries.

According to a further aspect of the invention, a

Method for applying an unfoldable

Adhesive frame providing a folded one

Adhesive frame and positioning the folded

Adhesive frame on a foldable frame holder with a plurality of frame elements which are designed and coupled to one another in such a way that the frame holder is opened and closed about a folding axis between a

folded, first state and an opened, second state with a predetermined frame geometry can be transferred. The method further comprises unfolding the frame holder about the folding axis and thereby forming the second state of the frame holder and Unfold the positioned adhesive frame. The

The method further comprises inserting an object into an object holder which is pivotally coupled to the frame holder, so that the object holder relative to the frame holder by means of pivoting about a pivot axis between an open, first state and one

closed, second state is transferable. In addition, the method includes pivoting the object holder about the pivot axis relative to the frame holder and thereby forming the second state of the object holder and

Positioning the object relative to the adhesive frame and arranging the unfolded adhesive frame at a predetermined position on a surface of the object by means of predetermined pressure on the object and / or the adhesive frame.

Using the method described, a

unfoldable adhesive frame easily and precisely arranged on an object and a reliable and

cost-effective sealing of an interior area against dust can be formed. The procedure described is

in particular by means of one of the previously described

Embodiments of the device can be carried out. Therefore, if applicable, all described properties and features of the device for applying an adhesive frame are also disclosed for the method for applying an adhesive frame and vice versa.

According to a preferred development, the method comprises fixing the adhesive frame in a predetermined position on the frame holder by forming a vacuum and sucking the adhesive frame onto the frame holder by means of one or more fixing elements of a respective one Frame element of the frame holder, which in each case comprises an opening which extends through the respective frame element and is fluidly coupled to an intake connection.

According to a further preferred development of the method, the arrangement of the adhesive frame on the surface of the object comprises pressing the object and the adhesive frame relative to one another by means of a pressing mechanism and

Applying a predetermined contact pressure to the object and / or the adhesive frame. Pressing takes place, for example, by exerting pressure on the object holder in the direction of the opened frame holder.

In addition, the method can further pivot the object holder about the pivot axis relative to the

Include frame bracket to the first state of

Training object holder. The method can further include removing the object with the applied adhesive frame from the object holder. For example, the

Object holder by swiveling about 90 ° from a vertical, first state to a horizontal, second state in which the with the

Surface of the object to be provided in the adhesive frame

Essentially parallel to a main plane of extension of the opened frame holder and the open one

Adhesive frame is located. Alternatively, the object holder can also form a first state at a different angle, so that, for example, only a pivoting of 60 ° or 45 ° is required to achieve the described one

Form alignment in the second state. A method for applying an adhesive frame can be carried out, for example, as follows: A material strip with a laminated adhesive frame is deposited manually, semi-automatically or fully automatically onto the device or onto the folded-in frame holder. About one

Position aids, an X / Y position of the adhesive frame is specified relative to the frame elements. The adhesive frame is made by hand, semi or fully automatically

provided guide grooves of the frame elements inserted. The adhesive frame is held in the guide grooves by means of a milled pocket and connected suction openings.

An upper cover of the adhesive frame can be pulled off, so that an adhesive surface of the adhesive frame is open at the top. The folded adhesive frame is by means of the hinged frame holder and the associated

mechanical folding mechanism, which for example comprises two or more hinges, opened to a stretched adhesive frame. Thus, the adhesive frame is available as a stamped part in its final geometry to be applied.

An object is inserted and positioned in a receptacle attached to the object holder. About a second

Folding mechanism, which enables the object holder to be pivoted about the pivot axis, the object is pressed onto the opened and ready-to-stick adhesive frame. A reproducible contact pressure over the entire frame surface of the adhesive frame is ensured by means of a mechanism that is based on pneumatics or hydraulics and / or has a servo motor. The second folding mechanism therefore has a comparable effect to that of a waffle iron and presses the object and the adhesive frame together. The second can follow Folding mechanism again by a predetermined angle

pivoted and thus the object holder can be opened again to release a removal of the object applied with the adhesive frame.

According to a further aspect of the invention, a

Adhesive frame a plurality of elements such

Adhesive frame can be converted from a folded, first state into an unfolded, second state with a predetermined adhesive frame geometry, the plurality of elements being set up in such a way that the

Adhesive frame in the second state along one

Main extension plane can be formed in a self-contained manner and has elongated frame sections which extend in at least three different directions with respect to their respective elongated extent.

Such an adhesive frame points in the complete

unfolded and self-contained state in

Mainly triangular, pentagonal or polygonal basic shape. Conventional square frame geometries, such as

Rectangular, square or route-like geometries have four sides or four frame sections with only two different directions of propagation. By means of the previously described device and the previously described method, however, triangular as well as quadrangular, pentagonal and polygonal frame geometries of an adhesive frame can be processed and applied to an object as desired.

The adhesive frame has, for example, a foam material with an adhesive bottom and an adhesive Top, which are each protected by a cover layer. The adhesive frame is in particular designed to relieve tension between the object and a component arranged opposite the object with respect to the adhesive frame

balance. Alternatively, the adhesive frame can also be designed as an adhesive tape which is double-sided

Gluing enables.

The adhesive frame can be designed with a closed or open structure, each of which enables a self-contained adhesive frame to be unfolded and clamped. In an open structure, for example, three elements are coupled to one another in series, which can be converted into a second state and a triangular one

Form the adhesive frame. In the case of a closed structure, the existing elements are coupled to one another in such a way that, even in the folded, first state, they form a self-contained material strip which is used for

Forming the second state of the adhesive frame is predetermined stretched.

For example, the adhesive frame can also have six or more sides and dispensing a hexagonal one

Allow adhesive frame. However, the device and the method can also be used to apply a square or rectangular adhesive frame. The individual parts or the elements of the adhesive frame are for

Example on a liner or a carrier layer

fixed in position in order to be brought into the specified final geometry by means of the application device. Also

Contour distorted geometries, contiguous and not

can be provided together as an adhesive frame, for example, to realize non-rectangular or asymmetrical geometries, such as a trapezoid.

According to a further aspect of the invention, this comprises a system, an object and an embodiment of the previous one

Embodiment of a device 1 for applying an adhesive frame 40, 50 to an object 60. The device 1 comprises a foldable frame holder 10 for receiving the adhesive frame 40, 50 with a plurality of frame elements 11, 12, 13 and 14, which are designed and coupled in this way are that the frame bracket 10 by opening and folding about a folding axis KA between a

folded, first state and an opened, second state with a predetermined frame geometry can be transferred (see Figures 2A-2C).

The device 1 further comprises an object holder 20 for receiving the object 60, which is pivotable about one

Pivot axis SA is coupled to the frame holder 10 by means of a coupling unit 24. The object holder 20 is relative to the frame holder 10 by pivoting around the Pivot axis SA can be transferred between an open, first state and a closed, second state, so that the adhesive frame 40, 50 can be unfolded by means of forming the second state of the frame holder 10 and by means of

Forming the second state of the object holder 20 can be applied at a predetermined position on a surface of the object 60.

The object holder 20 furthermore has a receiving unit 21 and a plurality of holding elements 22, which hold the object 60 in a reliable, safe and stable manner

allow predetermined position. The receiving unit 21 forms, for example, an open or closed rear wall for the object 60. The holding elements 22 can also be designed to be continuous or in one piece and form an upwardly open holding frame.

Terms such as "top", "bottom", "above", "below" or "top" and "bottom" refer to a possible alignment of the device 1, as illustrated for example in FIG. Accordingly, FIGS. 1A and 1B show exemplary views from above and FIG. IC shows an exemplary frontal view.

The device 1 or the frame holder 10 has a plurality of fixing elements 16, which are each designed to be applied

Fix adhesive frame 40, 50 in a predetermined position on the frame holder 10. According to the illustrated

Exemplary embodiment in FIGS. 1A and 1B, a respective frame element 11, 12, 13, 14 each has several

Fixing elements 16 to ensure a particularly secure hold of the adhesive frame 40, 50 to be glued. A respective fixing element 16 comprises one

Opening 18, which extends through the respective frame element 11,

12, 13, 14 and which is fluidly coupled to a suction connection 32, so that the adhesive frame 40, 50 to be applied can be fixed in a predetermined position on the frame holder 10 by means of a vacuum provided by the suction connection 32 (see FIG. IC). For example, each frame element 11, 12, 13, 14 each has a suction connection 32 which is coupled to a vacuum pump in order to set a predetermined negative pressure in the respective frame element 11, 12, 13, 14.

The respective openings 18 of a frame element 11, 12, 13, 14 are, for example, as indicated in FIG. IC, in each case by means of a channel or a channel system with the

associated suction port 32 coupled so that the adhesive frame 40, 50 placed on the frame holder 10 can be sucked in and thereby reliably fixed in position.

A respective fixing element 16 has, in addition to the opening 18, a recess 17 which adjoins the respective opening 18 in order to provide a suction force

To provide enlargement of the attack surface with respect to the adhesive frame 40, 50. Such a recess is for

Example in the form of a milled pocket on an upper side of the respective frame element 11, 12, 13, 14, which is provided for receiving the adhesive frame 40, 50 (see FIG. 2C). The respective recess 17 forms an elongated recess on the top of the respective

Frame elements 11, 12, 13, 14. Thus, each preferably has Frame element 11, 12, 13, 14 a plurality of fixing elements 16 with a separate vacuum supply.

In addition, a respective frame element 11, 12, 13, 14 has a guide groove for receiving the one to be applied

Adhesive frame 40, 50 on. Such a guide groove enables simple and reliable positioning of the

Adhesive frame 40, 50 on or in the

Frame bracket 10. Preferably, a depth of

The respective guide groove is designed to match the thickness of the adhesive frame 40, 50 to be applied, so that there is a certain protrusion of the adhesive frame 40, 50 placed on the frame elements 11, 12, 13, 14 in order to allow the adhesive frame 40, 50 to be applied easily and reliably to contribute to object 60. With reference to Figure IC is according to the supernatant described in the respective

Guide groove introduced adhesive frame 40, 50 then to

For example, an upper edge of the adhesive frame 40, 50 is formed above an upper edge of the frame holder 10

or arranged (see also Figure 4C).

In addition, the device 1 has a positioning element 31 which, as a positioning aid, enables the adhesive frame 40, 50 to be positioned in a predetermined manner in relation to a clamping plane of the frame holder 10. The

Positioning element 31 is, for example, as shown in FIG. 1A, laterally spaced as a dowel pin

Frame bracket 10 arranged to a position for the adhesive frame 40, 50 to be applied relative to the

Frame holder 10 specified. Such a pin-shaped element can be provided in a recess provided in the adhesive frame 40, 50 or in one of the adhesive frame 40, 50

associated cover and / or base liners are introduced, to enable easy alignment of the folded adhesive frame 40, 50 on the frame holder 10 and insertion into the guide grooves. According to an alternative embodiment of the device 1, the

Positioning element 31 can also be arranged on the frame holder 10, for example in an end region of the second frame element 12.

In addition, the device has an actuating element 19 which is designed to transfer the frame holder 10 between the first, folded-in state and the second, unfolded state. For example, as shown in FIG. 1A, the actuating element 19 is designed as a pin-shaped element on the frame element 13, which faces away from the object holder, and enables the frame holder 10 to be simply pulled out in a direction away from the object holder 20 when it is in the first, open state. A corresponding one

Folding the frame bracket 10 is done inversely to the

Unfold in one direction towards the object holder 20 in relation to its first, open state. Such opening and closing can be done manually or automatically by means of an appropriate mechanism and an actuator.

Figures 2A to 2C each show

schematic top view of an embodiment of the retractable and foldable frame holder 10 of the device 1 in

different states. FIG. 2A illustrates the first folded state, in which the four frame elements 11, 12, 13, 14 are arranged parallel to one another. A

Unfold the frame bracket 10 from the first,

folded state in the second, unfolded state takes place by means of a movement about the folding axis KA by pulling on the actuating element 19 along the indicated direction.

The folding axis KA represents an effective axis with respect to which individual frame elements 12, 13, 14 move when the frame holder 10 is opened. 1A to IC shown in FIGS

Device 1 is the frame holder 10 by means of

Frame element 11 and the coupling unit 24 with the

Object holder 20 connected. Thus, the frame element 11 does not move with respect to the folding axis KA when

Clamping the frame holder 10 and forming the second state. The further frame elements 12, 13, 14 perform a movement about the folding axis KA, which rotates,

Includes pivoting and / or translational movement.

The frame elements 11, 12, 13, 14 are coupled to one another, for example, by means of hinge elements which have an associated axis of rotation and an opening and closing of the

Allow frame bracket 10. According to FIG. 2B, the frame holder 10 is opened by the frame elements 12 and 14 rotating about the axis of rotation of the frame

Swivel and / or translational movement within the

Clamping level of the frame bracket 10 and remains aligned parallel to the frame member 11. In an alternative embodiment of the device 1 or the

The frame holder 10 can, for example, also make the frame element 11 move with respect to the folding axis KA, if the frame bracket 10 is complete, for example

pivotable via the coupling unit 24 with the

Object holder 20 is coupled. Frame holder 10 and object holder 20 are each set up and

coupled to each other that by forming the

a predetermined positioning of the adhesive frame 40, 50 and the object 60 relative to one another is made possible in the respective second states.

The frame holder 10 is opened essentially in a plane perpendicular to the folding axis KA or

Axes of rotation of the hinge elements, which represents an unclamping plane of the frame holder 10 and a main plane of extension of the unfolded adhesive frame 40, 50.

FIG. 2B shows an intermediate state of the frame holder 10 between the first, folded-in state according to FIG. 2A and the second, completely unfolded state according to FIG. 2C. An inverse sequence of movements enables the frame elements 11, 12, 13, 14 to be folded in and the first state of the frame holder 10 to be formed. The frame holder 10 can thus be reversibly extended and retracted and therefore enables adhesive frames 40, 50 to be dispensed continuously.

In addition, adjacent frame edges 15 of the respective frame elements 11, 12, 13, 14 are on top of one another

coordinated so that a simple opening and closing

Folding of the frame bracket 10 is made possible and the frame bracket 10 by transferring it into its second

Condition allows a desired unfolding of the applied adhesive frame 40, 50. It is not absolutely necessary that the respective frame edges 15 in the second state of the frame holder 10 according to FIG. 2C

contact each other and finish flush. A Reliable and stable base for the adhesive frame 40, 50 can also be formed with frame edges 15 spaced apart from one another.

FIGS. 3A and 3B show an exemplary embodiment of a foldable adhesive frame 50 which has four elements 51, 52, 53 and 54 which can be stretched to form a rectangular adhesive frame 50. In the first, folded state according to FIG. 3A, the adhesive frame 50 has a closed structure in which the four elements 51-54 are coupled to one another by means of coupling points 58 and form a coherent material strip. The respective elements 51-54 are designed with respect to their mutually adjacent edges 57 such that a second,

unfolded state of the adhesive frame 50 can be formed with a square basic shape according to FIG. 3B.

Such an adhesive frame 50 is formed, for example, in one piece by means of punching from a material strip provided, by punching out an inner region and arrow-shaped recesses in order to form corresponding edges 57 of the adhesive frame 50.
