Hinge strip tapes have a continuous tractor perforations in the middle of the Heftstreifenbandes or belt, as described for example in DE 203 00 950 U1. The tape has to be put into operation by one

driven spiked roller are placed so that the spikes of the drive roller engage in the tractor holes of the Heftstreifenbandes and in this way transport the tape. A continuous adhesive film applied to the binding tape, which is protected by a masking tape, makes it possible to hold it at a later time

Document. The carrier or masking tape is usually returned and passed into a receptacle or just below the Heftstreifenvorrichtung.

The circumference of the spiked roller depends on the length of the respective stitching strips. For a given, for example, a half turn of the spiked roller exactly one stitching strip is advanced so that no different

Staple strip lengths can be processed.

On the Heftstreifen belt according to DE 2 238 118 A is an endless

Heftstreifenreihe with a variety of stitching strips in a row and on one side attached to the carrier tape self-adhesive, wherein the Heftstreifen belt is pressed to transport pinch rollers against drive rollers.

EP 0 864 442 B1 discloses an apparatus for applying tacked tabs to a non-perforated document having a supply roll, diverting means and a take-up roll employing a carrier sheet having a plurality of detachable elongate tentering strips, each of the tabs an adhesive part and a non-adhesive, perforated part. The filing strips are arranged on the carrier film transversely to its direction of travel. Applied marks on the carrier film characterize the pitch. These individual filing strips are pulled over a release edge and thereby separated from the carrier film. When detaching a tape, it is glued to a sheet so that the non-adhesive part protrudes above the sheet edge with the perforation. The empty carrier film, which forms waste, is removed via take-off rollers and then wound up on the take-up roll.

From DE 24 08 108 A1 individual records collection strips are known, the dry or pressure-sensitive adhesive layer is covered with a peelable cover or cover strips.

DE 86 16 122 U1 discloses a Einhefthilfsmittel from a strip blank whose one longitudinal half has perforations, and the second longitudinal half is provided with a, covered by a peelable cover sheet adhesive layer. For manufacturing reasons, and for the sake of appropriate

Storage The attachment aids can be tailored to multiple the actual usage length, and through perforations in

Utility length intervals are divided and rolled up on rolls. For use, the strip portions are simply torn from the roll and manually tacked to a single sheet by means of the adhesive layer.

Adhesive strips for unperforated foil or sheet material,

Figure 2 is an endless unwinding for use in the invention

Device and

Figure 3 shows a control device for controlling the inventive

Contraption. FIG. 1 shows a device according to the invention for applying adhesive strips to a document supplied, for example, by a paper-processing device, in which endless strip-fastening tapes are arranged on one

Roll receiving 1 are rolled up as a supply or unwinding such as a movie on a spool. From the roll holder 1, a roll-off belt 2, as described later, unwound by means of a take-up roll 17, wherein the

Abrollband 2, as shown in Figure 2, from an endless, one-sided with

Abheftlöchern 3 provided striping tape 4, a non-perforated side of the tape tab tape 4 covering, continuous adhesive layer or a

Adhesive film 5 and the adhesive film 5 covering carrier or cover strip 6 consists.

The Abrollband 2 is guided by the roller holder 1 to a first guide roller 7, so that the Abrollband 2 is above a tape guide 8. The

Abrollband 2 is further guided by the first guide roller 7 to a second guide roller 9 with a relatively small diameter at which the Abrollband 2 is separated into the endless perforated adhesive tape 4 with adhesive film 5 and the endless cover 6, characterized in that the Abrollband 2 a deflection of for example, should be subjected to at least 180 °. When the second deflection roller 9 wraps around, the less flexible adhesive tape 4 separates with adhesive film 5 from the endless cover tape 6.

The endless tacking tape 4 is now guided on a cutting device 10 with a first knife 11 over on a Andruckbalken 12, to which a second knife 13 of the cutting device 10 is mounted, the cutting operation with the first knife 11 by lifting the Andruckbalkens 12 by means of one of an eccentric drive 14 driven lifting ram 15 can be brought into engagement and thereby separated from the endless tacking tape 4 a stitching strip 16 at a dashed lines in Figure 2 shown section line 22 and further pressing the cut perforated stitching strip 16 further upward.

The recirculated from the second guide roller 9 cover 6 is added to the

Winding roller 17 passed where it by means of a rotation angle controlled winding motor 18 is wound, which ensures accurate positioning of the stitching strips 16 by means of a mounted on the Andruckbalken 12 sensor 19, as will be explained below.

Above the pressure beam 12 is a document guide 20 for unperforated foil or sheet material, such as a sheet of paper, a document, a folding plan or folded paper stack, hereinafter referred to as document 21, arranged. To this document 21, the cut perforated adhesive strip 16 is pressed by means of the Andruckbalkens 12 so that it adheres with its provided with the adhesive film 5, the Abheftlöchern 3 side of the document 21 and the side with the Abheftlöchern 3 over the edge of the document 21st protrudes, so that the filing holes 3 are exposed. The document 21 is simply to a guide rail of the device for applying adhesive strip on the

Document guide 20 transported to a stop, not shown.

To load the device, the easily loaded endless unwinding belt 2 with perforated tape strip 4, continuous adhesive film 5 and masking tape 6 is threaded from the roller mount 1 to the pulleys 7 and 9 and only the

Masking tape 6 attached to the take-up roll 17. By turning in

Arrow direction by means of the winding motor 18 is now effected on the masking tape 6, the entire drive of the adhesive tape 4. By precise control of the winding motor 18 now any dimension of the stitching strip 16 can be achieved.

FIG. 3 shows a central control device 23, which is connected to the eccentric drive 14, the winding motor 18 and the sensor 19. In the control device, for example, the distance between the individual filing holes 3 is different

Hinge strips 4 stored. Thus, it can be detected via the sensor 19, which stitching strip 16 is provided on the roll receptacle 1, for example a DIN-Heftstreifen with 80 mm hole spacing or a Scandinavian stitching strip with 112 mm hole spacing.

From the sensor 19, the central control device 23 also receives the signal that signals the first filing hole 3. Thereafter, the control device 23 controls the rotation-angle-controlled winding motor 18 for positioning the stitching tape 4, until the second Abheftloch 3 is detected by the sensor 19. Then can by means of

Actuation of the lifting ram 15 can be raised by activating the eccentric drive 14 of the pressure bar 12 with the cutting device 10. The

Cutting device 10 cuts the stitching strip 16 in the required length at the cutting line 22 and the pressure bar 12 presses the stitching strip 16 against the document 21st

The idea underlying the invention is to design a stitching strip device such that different types of stitching strip strips but also different desired lengths of stitching strips can be automatically recognized and processed.

In the automatic stapling device according to the invention as in the prior art, an endless unwinding belt 2 with tacking tape 4, with

continuous adhesive film 5 and masking tape 6 used by the individual

Heftstreifen 16 are separated. The feed of the tape Heftstreifenes 4 is realized via the winding of the cover strip 6. For this purpose, the take-up roll 17, in which the cover strip 6 is clamped, by means of the rotational angle controlled

Winding motor 18 driven and wound so the cover 6. This

Winding the cover 6 takes over the same time the feed of

Hinge strip tape 4.

In contrast to the known automatic Heftstreifenvorrichtungen the tape feed is no longer realized via a driven spiked roller, but on the active controlled winding the existing cover strip 6 by a corresponding take-up reel 17. The winding roller 17 is driven by the rotation angle controlled winding motor 18, which ensures accurate positioning of the stitching strip 16. So on the one hand different

Heftstreifenarten and lengths are transported and on the other hand, the Traktorlochung is saved in the production of the Heftstreifenbänder 4. The feed is controlled via the sensor 19, which is under the pressure bar 12th

is arranged, that the individual Abheftlöcher 3 of the stitching strip 16 are detected. This sensor 19 thus assumes four important functions:

1. By detected by the sensor 19 distance of the individual Abheftlöcher 3 can be determined which stapling strip 16 is present. In this case, e.g. both a DIN-Heftstreifen with 80 mm hole spacing or a Scandinavian Heftstreifen with 112 mm hole spacing as a 2-hole punch, as well as a

Heftstreifen with hole intervals, as with 3-fold perforations or 4-fold

Punching given are to be recognized.

2. By detecting the Abheftlöcher 3 by means of the sensor 19, the exact cutting position can be determined so that the cut by the cutting device 10 of the tape strip 4 Heftstreifen 16 always the

required length (e.g., 2-hole or 4-hole). As a rule, 4-hole punching on the document 21 is realized by the application of two shorter stitching strips with 2-fold perforation, for the sole reason of saving the adhesive tape.

3. It can be recognized whether, after the joining operation, the stitching strip 16 has also been glued to the document 21 or has remained lying on the pressure bar 12.

4. The rising by increasing the diameter of the wound cover strip 6 on the take-up roll 17 feed rate of the stitching strip 16 can be determined by recognizing the individual Abheftlöcher 3 and

be compensated.

Furthermore, on the wound reel diameter and / or the

Feed rate can be determined how many strips of tape have already been processed by the role, and thus how many stitching strips are still present on the roll.

The easily inserted Abrollband 2, in the longitudinal direction one behind the other as a continuous strip material with endless tack tape 4, continuous

Adhesive film 5 and masking tape 6 is designed, is supplied as a roll and enough for more than 1500 documents. By the active motor-driven winding of the existing cover strip 6 by means of the corresponding take-up roll 17, a definable feed of the adhesive tape 4 is effected. The subdivision of the stitching strips 16 is sensed via the Abheftlöcher 3.

The liberated from the cover 6 stitching tape 4 is transported by the train on the cover strip 6 by means of the motor-driven take-up reel 17 on the Andruckbalken 12 with the cutting device 10 and the stroke of Andruckbalkens 12, the tape strip 4 is severed at the cutting line 22 and the stitching strip 16 is formed. By sensory detectable distance of the Abheftlöcher 3 can be used different types of stitching strips. The required evaluation of the stitching strip detection, cutting positioning and adaptation of the

Feed rate takes over the central control unit 23.

In addition, by the winding of the cover strip 6 this space saving and not disturbing collected and then can be easily disposed of.
