Achse 21 hat ein vergrößertes Gewindeteil 22 und streifrollen 13 eine größere Umfangsgeschwindigkeit einen flachen Kopf 23 mit einem Schlitz 24. Sie reicht haben als die Vorschubrolle 8, wird dann, wenn der durch eine öffnung 25 der Wand 6 hindurch und vordere Teil des Klebestreifens an den Abstreifrollen endet in der Bohrung 14 der Abstreifrolle 13. Durch 13 haften bleibt, der Teil des Klebestreifens zwischen Anziehen einer auf dem Gewindeteil 22 sitzenden 5 der Vorschubrolle 8 und den Abstreifrollen 13 geMutter 26 und durch Pressen der Innenfläche des streckt. Da die Oberfläche der Abstreifrollen 13 je-Kopfes 23 gegen die Wand 6 wird die Achse 21 mit doch kleiner ist als diejenige der Vorschubrolle 8, der Wand 6 des Trägers 1 des Gehäuses verbunden. wird das auf den Lappen 16 haftende Ende des Ähnlich wie die Achse 21 hat die Achse 21' ein Ge- Klebestreifens von den Abstreifrollen 13 getrennt und windeteil 22' und einen flachen Kopf 23' mit einem io durch die Öffnung 20 in Richtung auf ein Messer 33 Schlitz 24', und sie reicht durch eine öffnung 25 in weiter transportiert. Wenn der Klebestreifen aus der der gegenüberliegenden Wand 6 und endet in der Öffnung 20 in gewünschter Länge ausgetreten ist, Bohrung 14 der gegenüberliegenden Abstreifrolle 13. wird mittels des Messers 33 das entsprechende Mit Hilfe einer auf dem Gewindeteil 22' sitzenden Stück des Klebestreifens abgeschnitten.

It is enough than the feed roller 8, if the through an opening 25 of the wall 6 and the front part of the adhesive strip to the Stripping rollers ends in the bore 14 of the stripping roller 13. By 13 sticking, the part of the adhesive strip between tightening a 5 of the feed roller 8 sitting on the threaded part 22 and the stripping rollers 13 ge nut 26 and by pressing the inner surface of the stretches. Since the surface of the stripping rollers 13 per head 23 against the wall 6, the axis 21 is still smaller than that of the feed roller 8, connected to the wall 6 of the carrier 1 of the housing. If the end of the sticking to the flap 16 is similar to the axle 21, the axle 21 'has a joint adhesive strip separated from the stripping rollers 13 and threaded part 22' and a flat head 23 'with an io through the opening 20 in the direction of a knife 33 slot 24 ', and it extends through an opening 25 in further transported. When the adhesive strip has emerged from the opposite wall 6 and ends in the opening 20 in the desired length, bore 14 of the opposite stripping roller 13, the corresponding piece of adhesive tape seated on the threaded part 22 'is cut off by means of the knife 33.
Nut 26 ', the axle 21' is firmly connected to the associated wall. according to the F i g. 1 to 3 can be used for the simple

Durch die Verwendung der Feder- oder an den Gehäuse des Klebestreifenausgebers festplatte 38 ist jedoch eine Verkleinerung der Rolle 8 klebt. Dies wird durch die Hilfsabstreifrollen 70 vermöglich, weil kein Schlupf zwischen Klebestreifen hindert, von denen der Klebestreifen ebenso wie von und Rolle entsteht. den Abstreifrollen 13 abgestreift wird.Associated with the feed roller 8 is a curved adhesive strip that is removed from the stripping rollers 13 by a spring plate 38 (FIG. 3), which is brushed for pressing the and exits from the opening 20, relative Adhesive tape to the tabs 9, 9 'which is feed length, and if the opening 20 in a vertical directional role 8 serves so that it adheres to it. If the device is relatively large, the adhesive tape can be removed from the the outer diameter of the feed roller 8 and the stripping rollers 13 hang down, as shown in FIG. 4 shows so Surface of the tabs 9, 9 'are large, the spring 30 that there is a risk of it curling up and / plate 38 is omitted. By using the spring or hard disk attached to the housing of the tape dispenser 38, however, is a downsizing of the roll 8 sticks. This is made possible by the auxiliary scraper rollers 70, because no slip prevents between adhesive strips, of which the adhesive strip as well as of and role arises. the stripping rollers 13 is stripped.

Die Bahn des Klebestreifens verläuft von einem 35 F i g. 5 zeigt eine weitere Ausführungsform der ErPunkt auf der horizontalen Achse der Klebestreifen- findung, wobei der Antrieb der Abstreifrollen 13 rolle 7 um eine Zwischenrolle 40, dann um die Vor- unterschiedlich gegenüber der Ausführungsform nach schubrolle 8 zur Öffnung 20 des Gehäuses, wie in den F i g. 1 bis 3 ausgebildet ist.

Um eine rückwärtige Drehung der 40 durch ein Ritzel 82 bewirkt, das in die Außenver-Vorschubrolle 8 zu verhindern, ist eine Nase 39 vor- zahnung 15 der Abstreifrollen 13 und in eine Außengesehen, die von der Seite her in die Flanken der verzahnung 81 am Umfang eines Ansatzes mit geLappen 9 eingreift. ringerem Durchmesser der Vorschubrolle 80 eingreift.The path of the adhesive strip runs from a 35 F i g. 5 shows another embodiment of the ErPunkt on the horizontal axis of the adhesive strip invention, the drive of the stripping rollers 13 roll 7 around an intermediate roll 40, then around the front differently compared to the embodiment after Push roller 8 to opening 20 of the housing, as shown in FIGS. 1 to 3 is formed. The coupling between F i g. 1 is shown. The intermediate roller 40 is on a see feed roller and stripper rollers is here Axle 41 mounted. A backward rotation of 40 is effected by a pinion 82 which is inserted into the external feed roller 8, a nose 39 is pre-toothed 15 of the stripping rollers 13 and seen in an outside, from the side into the flanks of the toothing 81 on the circumference of an approach with gel flaps 9 intervenes. smaller diameter of the feed roller 80 engages.

Adhesive tape dispensers of the type mentioned are central bores 12. The stripping rollers 13 are on knows. In these adhesive tape dispensers is their outer periphery with tabs 16 and on one Size of the contact area between the adhesive 45 lug of reduced diameter with an outer strip and the stripping rollers about the same as the toothing 15 provided with the internal teeth between the adhesive strip and the feed roller, voltage 11 of the feed roller cooperates. the as a result, too much tension on the adhesive attachment with a reduced diameter is often in one piece streak is exerted, which can lead to tears. with the rest of the body of each stripping roller 13 out-further lie in the known devices that 50 forms, and it has a central bore 14. the Diameter of the stripping rollers in the size of the sum of the circumferential surfaces of the tabs 16 of the Feed rollers, as a result of which this known adhesive stripping roller 13 is now smaller than that of the cloth 9 Strip dispensers become bulky and unwieldy. and 9 'of the feed roller 8. Furthermore, the

The invention is therefore based on the object, the knife of the stripping rollers 13 smaller than that of the To create an adhesive tape dispenser, which has a feed roller 8. The stripping rollers 13 are thus on one side is handy and compact and with the other, that its outer diameter, if the front a tearing or tearing of the sticky stick roller and the stripping rollers assembled together fens between the feed roller and the stripping roller, somewhat over the outer circumference of the feed forges will. roll 8 survives. According to the invention, this is achieved by the circumferential speed of the stripping rollers 13 being greater than that of the Vordaß the diameter of the scraper rollers is smaller, pusher roller 8.

The area between the stripping rollers and the adhesive strip around axes 21 and IM in the vicinity of the opening is smaller than that between the front 20 and above the center point of the feed roller and the adhesive strip. 65 roll 8, but within the circumference of the latter, expediently, the stripping rollers are rotatably mounted. The stripping rollers 13 are connected downstream with the additional auxiliary stripping rollers, whereby the feed roller 8 is prevented by means of the external toothing 15, that longer from the adhesive strip and the internal toothing II and II 'are connected. the
