The surface 29 C is the embodiment. Therefore, like components are closest to face 36. The adhesive tape 11 extends denotes digits that differ only through the prefix 1 over the surface 29 Λ, then 5 downwards. In the following, only the lower length of the surface 29 B and firmly around the two in between in the construction will be discussed,

One recognizes by the fact that when the button 17 is pressed down, io most from FIG. 12 that a pair of hanging hangers rotates the rotatable part 29 around a right tab 40 are provided, each at an angle in a counterclockwise direction, the corner edges hanging tab for a side wall of the housing 110. pass through an arc of 90 °, as indicated by Ver - The hanging straps are attached at point 41. The same as the FIG. 2 and 5 can be seen. The upper and lower ends of the same are curved and face 29 B then comes to the location of the surface 15 towards one another in order to form support shoulders 42, the 29 C and lies opposite the surface 36. The other surfaces of the rotatable part 29 that engage under the side parts 124 of the frame 123 will correspond. Twisted in the path of the side walls 120 of the shaft end, and there is a subsequent blow 119, intermediate areas in the form of pegs 30 are in engagement with the fork ends 34 when angular projections 43 are provided, which is released on the button 17, so that the spring 18 20 to show each other. When the shaft 116 is pressed down as far as the stop 19, the rotatable part 129 also lifts (FIG. 2). The frame 23 carries an elastic adhesive tape 111, which is cut off around the rotatable part by the joint tab 37, which engages successively on the pin 30 of the anvil 138 and the respective corner when the rotatable part is rotated,
To prevent rotation in the opposite direction, however, after completion of the cutting process. before the full quarter turn of the rotatable The pawl members 31 are dimensioned so that the part is completed, the side walls 120 do not engage the rotatable part 29 a full stroke the projection 43 and press the hanging tabs a quarter turn, and when a quarter turn apart by wedge effect. Once released, the spring tab 37 is not in 30 frame 123 then moves into a position for contact with a pin 30. This arrangement presses on a section of tape when the shaft allows the rotatable member 29 to come into rest is depressed. If this shaft tion with the surface 36 can be brought. The spacer part 25 rotatably carries a cylindrical suspension bracket 40 free again and the anvil 38 moves and is thus back with respect to the abutment 35, so that its shoulders 42 are back into the stand part 26 .

The blocks 44 are of the springs 28 until the band portion 114 has been pressed against the resilient material so that they have the anvil surface 36 pressed. 50 always in relation to the corner edges of the rotatable part 29 is to hold part 129 in a detachable manner so that the band is cut with retaining pins 39 with certainty from the band.

The operation of the holding bridges 111 C, which consist entirely of adhesive pins 39, consists in the fact that they can hang on the adhesive tape and contribute to the fact that the tape 11 engages and perforates this in order to limit its correct position on the rotatable part 129 the same occurs when the rotatable part 29 is moved, but the band section can easily be removed. In addition, the retaining pegs 39 in 65 can be separated when the rotatable part is effective in such a way that it comes out of the separated tape pushing position.

The three-arm 51 pivotally mounted at the point 52 and extends in the direction of the stop pin carries a roller 53 which sits on an axis 54 and 56 and enables a section of tape to be attached to the side part 224 via this. The arm has to be looped 60 sen and, without any resistance, on a curved path that passes through the rollers 245 and, as when pulling the tape through the holding 49, when the arm is pulled further out of its normal pin 239,

When the frame 223 is moved downwards, through its normal range and in and the rotatable member 229 is pivoted into the pressing position, the inoperative position which brings in 65 is prevented the one-way clutch 65 any-Fig. 13 is shown in dashed lines. On the arm 51 a train of the adhering to the rotatable part 229 a spring 55 is attached and in a certain made of tape, and the roller 49 can not be pulled down a row of openings 56 in the housing wall when the arm 51 the stop pin 58 be -

Demzufolge bewirkt die Abwärtsbewegung des Rahmens 223, daß das Band direkt von der Rolle abgezogen und die abgezogene Länge in einer Schleife über die Rolle 53 gelegt wird, wenn diese durch die Feder 55 in die angehobene Stellung zurückgebracht wird, wobei die abgewickelte Länge wenigstens gleich der Länge der Oberfläche des drehbaren Teils 229 ist.has touched. Accordingly, the downward movement of the frame 223 causes the tape to be withdrawn directly from the roll and the withdrawn length to loop over the roll 53 when it is returned to the raised position by the spring 55, the unwound length being at least equal to that Length of the surface of the rotatable part 229 is.

Bänder, die nicht leicht reißen, lassen sich nicht so leicht durch die Haltezapfen 239 lochen wie leicht brechende Bänder, und wenn sie über die Rolle 53 geschleift werden, würde kein genügender Widerstand vorhanden sein, um eine Bandbemessungsicherzustellen. Aus diesem Grunde werden schwerreißende Bänder über die Rollen 49 und 245 geleitet, wobei die Rolle 53 sich in ihrem normalen Bereich befindet und nicht gebraucht wird, so daß die Vorrichtung in der gleichen Weise wie die in den F i g. 10 bis 12 beschriebene Vorrichtung arbeitet.Tapes that do not tear easily are not as easily pierced by the tabs 239 as easily broken tapes, and when looped over the roller 53 there would not be sufficient resistance to ensure tape sizing. For this reason, heavily tearing tapes are passed over rollers 49 and 245 , with roller 53 in its normal range and not being used, so that the device can be operated in the same manner as that in FIGS. 10 to 12 described device works.

Gewisse Teile der dritten Ausführungsform sind nicht beschrieben, etwa die Teile 214, 216, 218, 219, 220, 225, 226, 230, 231, 235, 238 usw., da diese Teile im wesentlichen den entsprechenden Teilen inCertain parts of the third embodiment are not described, such as parts 214, 216, 218, 219, 220, 225, 226, 230, 231, 235, 238 etc., since these parts are essentially the corresponding parts in

Als Beispiel für besondere Verwendungszwecke sei die Verwendung von Klebeband zum Anbringen eines Gegenstandes, beispielsweise eines Bleistiftes, auf irgendeiner Oberfläche, etwa einer Schaukarte, angegeben. Für derartige Zwecke sind besondere drehbare Teile erforderlich, wobei etwa bei der Vorrichtung nach den Fig. 19 und 20 ein drehbares TeilAn example of special uses is the use of adhesive tape for attachment an object, for example a pencil, on any surface, such as a map, specified. For such purposes, special rotatable parts are required, such as in the device 19 and 20, a rotatable part

66 vorgesehen ist, welches querverlaufende Kanäle66 is provided which transverse channels

67 in jeder Oberfläche aufweist. Jeder Kanal 67 ist so bemessen, daß er den Gegenstand aufnehmen kann, wenn die Oberfläche das Band gegen die gewünschte Hache drückt, und der Kanal kann mit einem Einsatz versehen sein, etwa einem Schaumgummieinsatz 68.67 in each surface. Each channel 67 is sized to receive the item can, when the surface presses the tape against the desired Hache, and the channel can with an insert, such as a foam rubber insert 68.

Die Vorrichtung nach der Erfindung ermöglicht also ein betriebssicheres Aufbringen von druckempfindlichem und/oder wärmeempfindlichem Klebeband. Dabei wird das Vorrücken und Abschneiden des Klebebandes so ausgeführt, daß es nicht an der Vorrichtung haftet. Dies wird im wesentlichen durch eine besondere Halteeinrichtung gewährleistet.The device according to the invention thus enables an operationally reliable application of pressure-sensitive and / or heat sensitive adhesive tape. This involves advancing and cutting The tape is designed so that it does not adhere to the device. This is essentially done through a special holding device guaranteed.
