Description

tape applicator

The invention relates to an adhesive tape applicator for applying an adhesive tape portion to an object, wherein the adhesive tape applicator is adapted to peel an adhesive tape end from an adhesive tape supply by relative motion of a movable portion and a stationary portion on the object, and apply it as an adhesive tape portion on the object.

Adhesive tape applicators are known in the form of adhesive tape rollers, which usually comprise a receptacle for an adhesive tape roll and a cutting edge for separating the adhesive tape. When operating such devices, the adhesive tape is usually grasped by hand, pulled off the adhesive tape roll in the desired length and separated from the adhesive tape roll by means of the cutting edge. The separated tape portion is then manually applied to an object. This procedure is not very comfortable, moreover, there is always the danger that the separated tape portion curls up or otherwise glued itself and thus unusable.

From the Japanese publication JP53-141736 seems to be taken from the figures, a hand-held device which is adapted to apply an adhesive tape portion by means of an automated, manual operation on a surface.

The published patent application DE 151 1481 also shows a device for dispensing and applying pressure-sensitive adhesive tape and is probably the closest prior art. This document discloses a hand-held device which peels off an adhesive tape end from an endless roll and applies it to a surface. The device comprises a rotatable punch element with 4 punches, wherein the adhesive tape end is perforated by arranged in the die surfaces spikes and deducted by the rotation of the punch member of the adhesive tape roll.

These known devices have a plurality of disadvantages in use, so that it is a possible object of the invention to propose modifications of such a device. The invention thus relates to a Klebebandaufbringvorrichtung and their preferred developments, as set forth in the claims, the following description and the accompanying drawings.

In the context of the invention, an adhesive tape application device is disclosed, which is suitable and / or designed for applying an adhesive tape section to an object. In particular, the adhesive tape applicator may also be referred to as an adhesive tape stamp or adhesive tape applicator. The adhesive tape of the adhesive tape portion is preferably formed as a pressure-sensitive adhesive tape, which is preferably withdrawn from an endless supply, in particular a roll. The adhesive tape can be coated or covered with adhesive on one or both sides. In particular, the adhesive tape-preferably also called a carrier-is transfer film and / or liner-free, that is to say without an additional liner or carrier tape which remains as waste. The tape portion is preferably as a one or both sides coated film, e.g. made of plastic or paper. Preferably, all of the contact surfaces of the tape applicator which contact adhesion-reducing surfaces, e.g., one or both sides of the adhesive tape, e.g. Surfaces with a low surface energy (Teflon) or with structures (e.g., corrugations, roughness, porosity, burls, grooves, etc.). The adhesive tape is particularly preferably designed such that it can in principle be pulled off in any desired length and / or is always designed to be constant in cross-section perpendicular to the longitudinal extent of the adhesive tape. The object can be of any desired design and is preferably freely selectable by the user and can be realized, for example, as two pieces of paper to be glued together.

The adhesive tape applicator can in principle be operated with external energy, but is preferably designed as a manually operated device. The adhesive tape applicator has a movable portion and a stationary portion placed on the object. In the course of movement, which is implemented by a movement of the movable portion relative to the stationary portion, an adhesive tape end is peeled off from the adhesive tape supply and applied as an adhesive tape portion on the object. The adhesive tape portion is separated from the adhesive tape supply prior to, during or after application of the adhesive tape portion on the object.

The adhesive tape applicator comprises an applicator which is formed and / or arranged to press the adhesive tape portion at an application position of the applicator on the object. The pressing can optionally be done by stamping and / or rolling and / or pressing. The applicator has at least one application surface for pressing of the tape section on the object.

In another, more preferred embodiment, the applicator undergoes a reversing and / or oscillating motion sequence, in particular the applicator is first pivoted in a direction of rotation and then pivoted back in the opposite direction. The swivel angle is preferably selected to be smaller than 360 °, in particular smaller than 200 °. Particularly preferably, the pivot angle is calculated around a pivot axis, which runs through the applicator.

Particularly preferably, the application device is designed as a stamp plate or bodies, which (r) allows a stamping of the adhesive tape portion on the object in a stamping direction, which is parallel or nearly parallel to the direction of movement of the movable portion.

Particularly preferably, in the last phase of the application and / or the pressing of the adhesive tape portion on the object, a largely or completely linear movement of the applicator parallel to the direction of movement, wherein the stamp plate or stamp surface is aligned parallel to the ground and / or perpendicular to the direction of movement , In a preferred development or alternative of the invention, the adhesive tape stamp is dimensioned such that the stamp surface in the outermost storage position for depositing the adhesive tape section shows a projection with respect to the placement geometry and / or lower edge of the adhesive tape stamp with respect to the object, wherein the supernatant elastic and / or yielding the Aufsetzgeometrie is formed. By this elastic supernatant uniform contact pressure of the tape section is achieved even with troubled ground. The elasticity is preferably dimensioned such that the stamp surface and the placement geometry are flush when applying the adhesive tape portion on an object with a flat contact surface.

In a particularly preferred embodiment of the invention, the applicator has a pressing member for pressing and / or depositing the adhesive tape end on a Andrückbock. The Andrückbock can identify any shape and is defined by a pressure surface, - A -

on which the adhesive tape end is pressed or stored. In particular, the adhesive tape end is positioned with a side coated with the adhesive layer on the Andrückbock.

For definition purposes, it is stated that the free end of the adhesive tape or adhesive tape stock is referred to as an adhesive tape end, which is then separated as an adhesive tape section, so that a new adhesive tape end is formed at the separation point.

In a development of this embodiment, it is provided that the application device carries out the rotational and / or pivoting linear movement independently of the pressed-on and / or deposited adhesive tape end. Generally speaking, the applicator is not connected at least in phases to the adhesive tape supply.

In a particularly preferred embodiment of the invention, the pressing member is movable in the applicator, in particular pivotally mounted and thus formed as part of a pivoting device. This embodiment of the invention enables an active pressing and / or depositing the adhesive tape end on the Andrückbock.

In a preferred structural embodiment of the invention, the pressing member is moved via a control device in the stationary section, which is designed for example as a curved path and / or Nutenführung. Preferably, the Andrückbock is disposed in the movable portion or fixedly connected thereto.

In an alternative embodiment, the Andrückbock is movable and / or controlled, so that the Andrückbock active with a pressing force and / or pressing movement acts on the Andrückorgan to take over the adhesive tape end adhesive.

In a preferred embodiment of the invention, the application device has a clamping device which is moved in particular with the application device and which is designed for the particular non-destructive clamping of the adhesive tape end. The clamping or the clamping device is arranged in the adhesive tape applicator such that the tensile force for the removal of the adhesive tape from the adhesive tape supply via the clamping or the clamping device is transmitted or initiated on the adhesive tape. This embodiment dispenses in particular with damage to the adhesive tape by perforation or the like. Preferably, in this embodiment, the removal of the adhesive tape from the adhesive tape supply is effected via a rotation and / or pivoting of the applicator, wherein the adhesive tape end is fixed by the clamping device and in particular exclusively by the clamping device on the applicator.

In a preferred constructive implementation of the invention, the clamping device comprises a pivotable and / or hinged in a bearing device clamping body for clamping the adhesive tape end to the applicator. Preferably, the clamping body is formed as a bar, which extends over at least half the width of the adhesive tape. Preferably, however, the clamping bar extends over the entire width of the adhesive tape. In the intermediate space between the clamping body and applicator the adhesive tape end is arranged. Preferably, the clamping body is only on one side of the applicator, e.g. via an arm, hinged, so that from the other, open side during a loading operation, the tape can be pushed under the beam or the clamp body.

Preferably, the clamping device is designed so that the clamping body in the storage device can assume a stable and a metastable position. In the opened state, the clamping body is supported in a metastable manner and is preferably prestressed so that when the angle of the clamping body about its own pivot axis changes by a few degrees, e.g. in a range of 0 ° to 3 °, a triggering takes place and the clamping body automatically changes to the stable, closed position. In the closed position, the clamping body is pressed with bias on the applicator to effect the clamping. In a preferred structural realization, the bearing device of the clamping body is realized as a prism bearing, wherein the pivot point is arranged in tips of the clamping body, which are arranged on or in the applicator.

In an optional development of the invention, the clamping device on a control handle for manual switching between the two positions. The control handle is designed for example as an additional, in particular fluted tab.

In a supplementary development of the invention, the clamping device, in particular the clamping body, and the Andrückbock at least temporarily interlocking areas, so that the adhesive tape end can be transferred from the Andrückbock to the clamping body. In particular, clamping body and Andrückbock are geometrically formed so that temporarily overlapping and / or toothed gripping the tape end is given. In this way, the transfer of the adhesive tape from the Andrückbock to the clamping body and thus configured to the applicator functionally reliable. In a further development of the invention, the application device comprises a first cutting device and the stationary section comprises a second cutting device, wherein the first and second cutting device are formed together to separate the adhesive tape section from the adhesive tape roll. To implement the separation process, an interaction of the first and the second cutter is required. The separation is preferably accomplished by shearing, with the adhesive tape held in place in the separation zone perpendicular to the cutters to prevent squeezing of the tape between the cutters.

With the aim of further increasing the reliability, it is preferably provided that the first and / or the second cutting device is suspended and / or mounted elastically and / or elastically perpendicular to the cutting direction. As a result, the advantage is achieved that set the correct cutting positions of the cutting devices automatically. In particular, the cutting devices are arranged at an angle to one another in such a way that a shearing separation of the adhesive tape results, the shearing initially starting from a first point on the adhesive tape and then continuing through the adhesive tape.

It is particularly preferably provided that the second cutting device is arranged offset relative to the first cutting device in the cutting position toward the center of the applicator. Due to the fact that, in the cutting position, the second cutting device is positioned between the first cutting device and an adjacent plate edge of the application device, it is achieved that the adhesive tape is optimally prepared during the separation. Thus, this structural design also serves to increase the reliability of Klebebandaufbringvorrichtung.

With the aim of avoiding malfunction or the like of the adhesive tape applicator in the event that the adhesive tape application process is not completed, it is preferably provided that a retraction securing is integrated between the stationary and movable portions, which retracts the movable portion only after the Applying the adhesive tape section on the object and / or allowed after the bottom dead center and / or after the completed pressing movement. This withdrawal protection is represented, for example, by a trajectory with a way out, a way back and two connecting change points, the way out is formed with a detent, which holds the movable portion in premature relief before the lower change and / or reversal point in the current position ,

A preferred embodiment of the adhesive tape applicator thus relates to an embodiment in which the applicator operates oscillating and / or reversing and the Applicator having as functional components a clamping device, a Andrückorgan, a stamp surface and a cutting device.

In a preferred embodiment, the movable section is connected and / or covered with a lid, which at the same time functions as a control panel. Preferably, the cover overlaps the stationary portion, so that a risk of injury is prevented by pinching in the operation of Klebebandaufbringvorrichtung. It is preferably provided that for a change of the adhesive tape supply, in particular the adhesive tape roll, the lid is detachably and / or separably formed by the body of the adhesive tape applicator.

Preferably, the movable portion has a pivot joint, which is designed, after removal of the lid, a partial section of the movable portion with the roller and optionally supplementary with the applicator to swing, to facilitate the change of the tape supply, in particular the roll of adhesive tape.

For the return of the movable portion of the pressing position of the applicator is preferably an elastic means, in particular a coil spring, is provided, which is stretched in the manual operation of the Klebebandaufbringvorrichtung and due to the stored energy, the movable portion returns to the initial position. The elastic device is in particular designed so that in the normal rest position this has a certain bias sufficient to push out the movable portion with spring force so far when the lid is open, that a pivoting of the portion of the movable portion is made possible.

Further features, advantages and effects of the invention will become apparent from the following description of a preferred embodiment of the invention. Showing:

1 shows an adhesive tape stamp 1 as an embodiment of an adhesive tape applicator according to the invention in a frontal view from the front. The adhesive tape stamp 1 is placed on an object 2, which is to be provided with an adhesive tape section 3 (FIG. 2).

The adhesive tape stamp 1 in FIG. 1 is in the rest position and shows an upper housing part 4, which can be gripped and operated by one hand (not shown) during the operation of the adhesive tape stamp 1. When the adhesive tape stamp 1 is actuated, the housing upper part 4 is moved relative to a housing lower part 5 which is stationary on the object 2 is arranged, moved. The stamp or movement direction is shown in the figure 2 with an arrow 6.

The housing upper part 4 is formed in a cross-section perpendicular to the direction of movement 6 in the coarse form as a rectangle and encompasses and / or engages over the slightly smaller in cross-section housing base 5, so that the operation of the adhesive tamping 1 is done without risk of injury to the user. The arrangement of the upper housing part 4 and the lower housing part 5 may also be referred to as upside-down arrangement.

By actuating the adhesive tape stamp 1, the adhesive tape section 3, which is shown in dashed lines in FIG. 2, is pressed onto the object 2. The extension of the adhesive tape section 3 is aligned approximately perpendicular to the direction of movement 6. However, FIG. 2 shows the adhesive tape stamp 1 only shortly before the deposition of the adhesive tape section 3, which is why it is also shown in dashed lines.

Figures 3 and 4 show the Klebstabstempler 1 in the same state as in Figures 1 and 2, but from the other side in an open or partially cut representation.

In the region of the upper housing part 4, an adhesive tape roll 7 is rotatably mounted, from which an adhesive tape 8 is removable. The adhesive tape 8 is designed as a so-called pressure-sensitive adhesive tape and in this example is coated on one side with an adhesive.

Roughly illustrated, the adhesive tape 8 runs from the adhesive tape roll 7 to a plate body 9 - also called a plate housing - on which it is clamped in the rest position of the adhesive tamping device 1 shown in FIG.

When transferring from the rest position in Figure 3 in the stripping position of Figure 4, the plate body 9 is linearly displaced in the stamping direction 6 and at the same time pivoted about a arranged in the plate body 9 plate axis 10 by nearly 180 °. By pivoting the tape 8 is stretched over a stamping surface 1 1, which is arranged on the plate body 9, and subsequently placed on the object 2 in the region of the clamped adhesive tape end on the object 2 and - at a completion of the 180-degree pivoting - Unrolled on the object 2 or stamped and pressed. As will be explained below, the adhesive tape 8 is separated at an appropriate location, so that, as a result of the movement, the adhesive tape portion 3 is pressed onto the object 2 separated from the adhesive tape 8.

In order to explain the exact functioning of the adhesive tape stamp 1, illustrations are used below in which regions or parts of the adhesive tape stamp 1 are graphically suppressed.

Thus, FIG. 5 shows, in a schematic three-dimensional view, only the upper area with the upper housing part 4 in the opened adhesive tape stamp 1, in which a slider 13 is arranged. The slider 13 is displaced together with the upper housing part 4 in the stamping direction 6 when the adhesive tape stamp 1 is actuated. It comprises a roller receptacle 14 for receiving the adhesive tape roll 7, carries a tape deflection roller 15 for deflecting the adhesive tape 8 and the plate axis 10, about which the plate body 9 is pivoted upon actuation. The band deflection roller preferably has an adhesion-reducing surface for the use of double-sided coated adhesive tape. Upper housing part 4, slide 13, plate axis 10 and thus plate body 9 perform the same linear motion during actuation, wherein the plate body 9 is pivoted back and forth during the linear movement.

As a further functional elements of the slider 13 carries a ready-holding frame 16 - also Andrückbock called - with a ribbed surface 17 for adhesive storage of the adhesive tape 8 and a socket-side, toothed gripping contour 18, whose function will be discussed later. Opposite is in the slide 13, a cylindrical pin each formed on both sides as a pivot axis 19. As is apparent from Figures 3 and 4, a pivot joint body 20 is pivotally mounted on the pivot axis 19.

6 shows the lower housing part 5 of the adhesive tape stamp 1 together with the one-piece swivel joint body 20. As can be seen from this illustration, the swivel joint body 20 has two receptacles 21 for the cylindrical pins of the swivel joint axis 19 (not shown). In the direction of movement 6 extending from the pivot joint body 20 guide webs 22, which are guided positively in complementarily shaped guideways 23 in the lower housing part 5, so that there is a linear guide for the pivot joint body 20 in the lower housing part 5.

In the central portion of the pivot joint body 20, a spring receptacle 24 is provided, which is open in the direction of movement 6 down and receives a coil spring 25, which against the lower housing part 5 is supported. To guide the spring 25 and optionally as an end stop of the adhesive tape stamp 1 a mandrel 26 is integrally formed on the lower housing part 5, on which the coil spring 25 is attached. The coil spring 25 carries out the task to build up a counter force in the operation of the adhesive tape stamp 1 and after pressing the adhesive tape section 3 on the object 2 due to a stored spring energy, the housing upper part 4 with the slider 13 automatically returned to the starting position.

In the figure 6, two latching hooks 27 can be seen for the housing lock, which are integrally angefromt to the lower housing part 5, the lugs are turned outwards and which are designed to lock the upper housing part 4. When moving back the upper housing part 4 by the spring force of the coil spring 25, the upper housing part 4 is pushed so far against the direction of movement 6 until it engages with the latching hooks 27 in corresponding projections of the upper housing part 4.

As is apparent in particular from Figure 5, the upper housing part 4 corresponding to the latching hooks 27 unlocking 28, which are formed as tabs formed on one side and the actuation of the locking hooks 27 can be unlocked so that the upper housing part 4 are deducted from the lower housing part 5 can.

After the description of the main components of the adhesive tape stamp 1, the movement sequence of the adhesive tape stamp 1, beginning with the rest position in FIG. 3, will be described below:

Returning to FIG. 3, this shows the plate body 9 with a stamp surface 1 directed against the direction of movement 6. The adhesive tape 8 is deflected over the band deflection roller 15 and is clamped by means of a clamping bar 29 to an end face 30 of the plate body 9. The clamping bar 29 and / or the end face 30 is preferably, in particular when using double-sided adhesive tape, provided on the contact surface with the adhesive tape 8 with a adhesion-reducing surface. The rest position is the starting position for the operation, wherein the slide 13 is at a top dead center.

The coil spring 25 is under a residual stress to move the slider 13 after removal and unlocking of the upper housing part 4 for a replacement of the adhesive tape roll 7 and a tilting over the pivot axis 19 upwards. The limitation and the hold of the upper housing part 4 relative to the lower housing part 5 is effected by the latching hooks 27. The free adhesive tape end 12 is free to the ready-holding block 16 or arranged largely free to this. Upon actuation of the adhesive tape stamp 1 in the direction of movement 6, the plate body 9 is set in a pivoting movement about the plate axis 10, wherein adhesive tape 8 is pulled off the adhesive tape roll 7. To increase the reliability of the adhesive tape 8 is deflected defined by the Bandumlenkrolle 15. The clamping bar 29 clamps the adhesive tape end 12 against the end face 30 of the plate body 9.

FIG. 4 shows the adhesive tape stamp 1 when the adhesive tape 8 is pressed onto the object 2, wherein the adhesive tape 8 is already placed in the region of the adhesive tape end 12 on the object 2 in the region of a plate edge 31 of the plate body 9.

After or during placement of the clamping bar 29 is released from the end face 30, so that the clamped adhesive tape end 12 is released. The plate angle of the stamp surface 1 1 to the surface of the object 2 is in the illustrated embodiment 1 1 °, wherein in alternative embodiments, a range of 0 ° -20 ° can be used.

While the upper housing part 4 is moved further in the direction of movement 6, the plate body 9 completes the 180 ° pivoting, the following actions taking place simultaneously or almost simultaneously:

The clamping bar 29 is opened further and releases the clamped adhesive tape end 12 completely. A cutting device 32, which will be explained in more detail later, separates the adhesive tape 8 by means of a shear in the region of the opposing plate edge 33. A pressing member 34 presses the newly formed tape end 35 in the direction of the ready-holding block 16 and places or glues the new adhesive-tape end 35 to the ready-holding bracket 16. The pressing member 34 is preferably, in particular when using double-sided adhesive tape, provided at the contact surface with the adhesive tape 8 with a adhesion-reducing surface.

In the state of the adhesive tape stamp 1 shown in FIG. 7, the adhesive tape section 3 is pressed onto the object 2 and released. Preferably, the stamping surface 1 1 is provided for pressing the adhesive tape portion 3 on the object 2 with an elastic and / or resilient coating to distribute the pressure during pressing.

After successfully depositing, stamping and / or pressing the tape portion 3 on the object 2, the operating force of the operator is withdrawn and the slider 13 against the operating direction 6 by the spring force of the coil spring 25 together with the upper housing part 4 postponed. The clamping bar 29 is opened to release the tape portion 3. The new free end of the tape 35 is stored on the provisioning stand 16, so that the plate body (9) is unconnected with the adhesive tape 8 in this state.

During the backward or upward movement of the plate body 9 pivots back in the opposite direction, thus undergoing the pivoting of 0-180 ° in the opposite direction, i. from 180 ° -0 °.

In FIG. 8, the adhesive tape stamp 1 is shown shortly before returning to the rest position according to FIG. 3, with the plate body 9 being almost completely swung back. In this state, the clamping bar 29 is fully opened and the new adhesive tape end 35 is adhered to the ready-holding block 16. The new adhesive tape end 35 projects beyond the ready-holding bracket and projects into a region between the clamping bar 29 and the end face 30 of the plate body 9. Subsequently, the new strap end 35 is caught by the clamping bar 29 and pressed against the end face 30 of the clamping bar 29 by a snapping movement of the clamping bar 29 Plate body 9 clamped. In this case, the new adhesive tape end 35 is removed from the ready holding block 16. In order to make the transfer of the new adhesive tape end 35 functionally secure from the ready-holding bracket 16 to the clamping bar 29, an end section 36 facing the clamping bar 29 and the edge of the clamping bar 29 facing the end section 36 are provided with interlocking contours, in this case toothings to allow overlapping gripping. After the capture of the new adhesive tape end 35, the adhesive tape stamp 1 returns to its rest position according to FIG.

Figures 9 and 10 respectively show the plate body 9 in a schematic three-dimensional representation, wherein in Figure 9, the clamping bar 29 is spaced from the end face 30 of the plate body 9 and thus arranged non-clamping. The figure 10, however, shows the clamping bar 29 clamped against the end face 30.

The clamping bar 29 is attached on one side and in one piece via a clamping arm 37, so that the gap between the clamping bar 29 and end face 30 is freely accessible from the opposite side. In this way it is easy to insert an adhesive tape 8.

Also integrally connected to the clamping bar 29 and the clamping arm 37 is a bearing portion 38 which is mounted in a bearing cup assembly 39 of the plate body 9 via a prism support 40. For this purpose, the bearing portion on both sides in each case a prism end 41 with a tip and two adjoining edges, wherein the clamping bar 29 is a pivotable mounting of the clamping bar 29 on the tips of the prism ends 41 very is implemented with low friction. The edges of the prism end 41 each define an end stop in the bearing cup assembly 39.

A spring element 43 in the form of a prestressed leaf spring presses the movable part of the prism bearing 40 against the bearing cup arrangement 39 in the plate body 9. The spring element 43 biases the clamping bar 29 in such a way that it can assume two stationary positions, the prism bearing 40 being asymmetrically bistable is.

The open position of the clamping bar 29 shown in FIG. 9 is metastable, so that a slight pivoting movement about the tips 42 is sufficient to cause the clamping bar 29 to snap shut. By contrast, the position of the clamping bar 29 shown in FIG. 10 is stable, the clamping bar 29 being actively pressed onto the end face 30 by means of the spring element 43.

In order to facilitate manual insertion of the adhesive tape 8, the prism support 40 has an actuating beam 44 arranged parallel to the clamping beam 29 with an actuating portion 45. By pressing the actuating portion 45, the prism support 40 can move from the position in FIG. 10 to the metastable position of FIG 9 are led. The control of the prism storage 40 results from an interaction of the plate body and clamping bar side control pins with control devices in the housing base 5 and / or the slider 13, in which controls and / or control surfaces, in particular control grooves are introduced. The clamping of the clamping bar 29, for example, by pressure on a control pin of a control surface of the slider 13. The spring element 43 is inserted biased and generates the contact pressure.

Figures 1 1 and 12 also show the plate body 9 in a schematic three-dimensional representation, in which case, however, the emphasis is placed on the pressing member 34. The pressing member 34 is also formed like a bar and pivotally received in the plate body 9. FIG. 11 shows the pressing member 34 in a pivoted-back position and in FIG. 12 in a pressing position. As an alternative to the pivoting receptacle shown, the free end of the tape 35 can be pressed against the slide-side stand holding block 16 after the cut by plate-body-side rotatable and / or linearly movable and / or resiliently pressing members, so that it adheres there with sufficient position accuracy and stability.

The control of the Andrückorgans 34 is transmitted by means of a housing-side control cam on one or two control cam 46 of the Andrückorgans 34.

The plate body 9 thus combines a plurality of functions and is an actor in the adhesive tape stamp 1. The pressure of the operating movement is with the plate body 9 in a Swivel movement translated. The drive is via a modified gear segment 53 for the pivoting movement and a pin-in-groove guide for the phase of placement. The plate body 9 forms a structure or housing and accommodates the other mechanical functional elements shown.

Figures 13 and 14 illustrate the transfer of the free adhesive tape 35 shortly before returning to the rest position of the Klebstempelstemplers 1. The ready-holding frame 16 has in the end portion 34 two teeth 47, whereas the clamping bar 29 has two complementarily formed edge recesses 48. When catching the new adhesive tape end 35 by the clamping bar 29, the clamping bar 29 snaps past the ready-holding block 16 so that the edge cut-outs 48 are penetrated by the teeth 47. The new adhesive tape end 35 adhering to the holding stand 16 also adheres to the teeth 47, so that it can be reliably removed from the clamping bar 29 by the overlapping area. FIG. 14 shows the clamping bar 29 in the clamping position.

The shear movement for separating the adhesive tape 8 will be explained with reference to FIG. The cutting device 32 comprises a first cutting edge 49, which is fastened to and / or moved with the plate body 9, and a second cutting edge 50, which is arranged in the housing lower part 5. The second cutting edge 50 is rigidly arranged, the first cutting edge 49 is - as is also apparent, for example, from Figures 1 1 and 12, elastically suspended and particularly preferably formed integrally with the spring element 43. The first cutting edge 49 has a catching extension 51, which is bent away from the plate body 9 with respect to the cutting edge 49. In a further continuation in the direction of movement 6 of the Fangfortsatz 51 catches the second cutting edge 50 a. Due to the bending of the catch extension 51, the first cutting edge 49 is pressed elastically away from the plate body 9 so that the second cutting edge 50 is inserted between the plate body 9 and the first cutting edge 49. In this way, the adhesive tape 8 is held almost perpendicular to the cutting edges 49, 50. The first cutting edge 49 and the second cutting edge 50 are optionally formed at an oblique angle to one another and / or with a beveled cutting path, in order to allow shearing of the adhesive tape 8. Viewed from an abstract perspective, the adhesive tape 8 bridges a plate-body-side channel in the stamp face 1 1 during the separation, which runs transversely to the band direction and which is bounded laterally by the first cutting edge 49. In this imaginary channel, the second cutting edge 50 dives in the course of the separation. The arrangement of the sheaths 49 and 50, the risk of crushing the adhesive tape 8 and thus an incomplete separation is reduced. The control of the cutting process results from the superposition of pivotal and linear movement of the plate body 9 or during the linear residual stroke (see Figure 19). A not completed downward movement during pressing in the direction of arrow 6 to the bottom dead center requires a controlled handling to give the device reliability in case of incorrect operation or to increase the disturbance immobility. Optionally, therefore, the adhesive tape stamp 1 on a retraction protection, which prevents premature termination of the pressing / Ablegvorgangs an uncontrolled operating condition. The retraction assurance is designed so that an upward movement of the slider 13 is possible only on reaching and / or in the region of the bottom dead center / reversal point. A spring back up before reaching the bottom dead center is prevented by the return protection. Through them, the slider 13 remains near the point of discharge and thus freezes the movement. In a preferred implementation, the retreatment shows a two-way guideway with two change and / or reversal points. A pivot hinge side guide pin is designed as a resilient hook, in particular latching hooks. In the downward movement of the hook passes through a provided with latching rail. At the bottom dead center of the stroke, the hook goes out / steers and jumps into an untoothed guideway. During the upward movement of the slider, he passes through this track to near top dead center. At top dead center, the hook is deflected by a suitable shape of the control cam and brought to the starting point of the downward trajectory. At rest, he is relaxed. The latching steps are oriented so that an upward movement of the hook is prevented in the latched rail provided. In another possible embodiment, the principle is conversely structurally executable, that is, the hook is disposed on the lower housing part 5 and the locking rail on the pivot slide.

Finally, FIG. 16 illustrates the replacement process of the adhesive tape roll 7. For a change, the upper housing part 4 is first unlocked and completely removed by actuation of the unlocking elements 28. In a next step, the slider 13 is pushed out by the spring force of the coil spring 25 so far against the direction of movement 6, that the slider 13 can be pivoted relative to the pivot joint body 20, for example by an angle of about 60 ° or in a range of 20 ° to 90 °. In this state, the clamping bar 29 can be opened by actuation of the actuating portion 45 and a new adhesive tape roll 7 is inserted and the free adhesive tape end 35 are properly positioned. After snapping the clamping bar 29, the slider 13 can be pivoted back again and pushed into the lower housing part 5. On the clamping bar 29 may optionally be arranged a cutting contour, which allows cutting, separating or tearing off the adhesive tape 8 after inserting the new adhesive tape roll 7. After placing and locking the upper housing part 4 of the adhesive tape stamp 1 is then ready for use again. FIG. 17 shows, in a schematic three-dimensional representation, the housing lower part 5 in a partially cut-out form in order to illustrate the control elements for controlling the plate body 9 and the further movable components. In the illustration, the front wall is graphically suppressed. In the figure 17, the mandrel 26 for receiving the coil spring 25 and the guideways 23 can be seen. Approximately in the middle of the back of the housing base 5, a main control element 52 is integrally formed, which cooperates with a gear segment 53 which is formed on the plate body 9, or arranged (Figures 9 and 10). The main control element 52a has a lateral open guideway 54, which in the direction of movement 6 in the course initially shows a recess which terminates in a ramp-like trajectory. The gear segment 53 is asymmetrical in plan view and has a central main tooth 55, which engages in the guide track 54. In the bottom region of the housing lower part 5, a plate cam control path 56 for controlling the plate cam 57 (Figures 9 and 10) is arranged, whose function will be explained with reference to the following figures. Laterally next to a further control track 58 is arranged to control the Andrückorgans 34, which cooperates with the control cam 46.

On the front of the lower housing part 5, a corresponding main control element 52b can be seen, which is integrally formed on the graphically suppressed front wall and meshes with a second gear segment 53 of the plate body 9. The front main control member 52b carries a longer guide than the rear main control member 52a, in which the guide track 54 merges with the disc cam control path 56.

FIG. 18 shows the adhesive tape stamp 1 with partially suppressed components in one phase, wherein the plate angle of the plate body 9, in particular the stamp surface 1 1, occupies approximately a 45 ° angle to the ground. In this phase, the plate cam 57 runs on the plate cam control path 56, wherein the control cam track occupies an angle of approximately 40 ° to the ground.

In FIG. 19, the plate cam 57 has reached one end of the plate cam control path 56, so that the plate cam 57 subsequently moves parallel or nearly parallel to the direction of movement 6 in the direction of the substrate. This embodiment is exemplary for the implementation of a mechanism that makes it possible that in the last phase of depositing the adhesive tape section 3 on the ground a linear lifting movement of the die surface 1 1 takes place. The stamp surface 1 1 is aligned parallel to the ground. By this linear and parallel to the direction of movement 6 aligned movement is a uniform pressing of the adhesive tape portion 3 allows on the ground. In this lifting movement of the clamping bar 29 has the Kiebebandabschnitt or the free adhesive tape end 12 completely released. Finally, in FIG. 20, an overpressing of the adhesive tape stamp 1 is shown, wherein in the absence of a substrate, the stamp surface 1 1 would project beyond the contact surface 57 of the adhesive stamp 1. This embodiment has the advantage that, in the case of an elastic design of the stamping surface 11 or its lining, the adhesive tape section 3 can also be applied to a turbulent substrate, the irregularities in this example being compensated for by the elasticity of the coating. For the implementation of this supernatant but several, any options are conceivable: On the one hand, an elastic plate-side Andrückfläche can be used. Alternatively or additionally, the mechanical components, in particular the control elements, can be dimensioned in such a way and made elastic that they allow the overpressing. Another alternative or supplement is to make feet or Aufsetzgeometrien for placing the adhesive Tampers 1 on the ground elastic so that they yield under pressure and allow the supernatant.

In addition, it should be noted that at least one of the end faces of the clamping bar 29 has control elements for the clamping bar control. Preferably, these are mounted on dsm clamp arm 37. They work in conjunction with control elements in the housing base 5 and the slide 13. The controls are formed in a suitable geometry and cause the opening and closing of the clamp.
