Abstract
Arranged inside a housing (33) of the inventive device (1) are a supply spool(2) for a carrier band (5) coated with the film (4), a winding spool (3) for accommodating the carrier band (5) separated from the film (4), and an application device (6) which diverts the carrier band (5). The application device (6) protrudes with an end (8) thereof, said end diverting the carrier band (5), out of the housing (33) and can pivot about the longitudinal direction of the carrier band (5) which is guided through and out of the housing (33). The carrier band (5) runs in an unsupported manner from the supply spool (2) to the application device (6). Despite the pivotability of the application device, there is virtually no risk of the film applied on the carrier band from being damaged or from being prematurely detached from the carrier band.
Description
A Dispenser for Transferring a Film from a Carrier Tape to a Substrate This invention relates to a dispenser for transferring a film from a carrier tape to a substrate comprising a housing in which a feed spool for a carrier tape coated with the film, a take-up spool for taking up carrier tape separated from the film and an applicator element re-directing the carrier tape are accommodated, the applicator element projecting from the housing at its end which re-directs the carrier tape and being designed to pivot about the longitudinal axis of the carrier tape guided out of the housing.
There are various known hand-held dispensers for transferring a film from a carrier tape to a substrate. The film disposed on the ribbon-like carrier tape can be an adhesive film or a masking composition for covering incorrect characterslsymbols applied to paper.
A dispenser of the type mentioned at the beginning is known from EP
0 656 308 B1. Two spools rotating in opposite directions are disposed in a housing, one forming the feed spool and the other the take-up spool. The carrier tape coated with the film is wound onto the feed spool, the film being applied to the outside of the carrier tape. The carrier tape travels from the feed spool located in the rear part of the housing to the applicator element over a pin-like tape guide and, at the applicator element, is re-directed over a V-shaped applicator lip. If the applicator lip is pressed onto a substrate, for example paper, and at the same time is moved in the plane of the substrate, the film separates from the carrier tape and adheres to the substrate.
After re-direction at the applicator lip, the carrier tape is guided back into the housing and passes over another pin-like tape guide onto the core of the take-up spool which is located in the front part of the housing.
The first of the two above-mentioned tape guides is required for the fresh as yet unused carrier tape because, on the one hand, the feed spool is located in the rear part of the housing and the take-up spool in the front part of the housing and, on the other hand, the two spools and the applicator element are arranged approximately in a straight line. When, after a certain period of operation, a relatively large amount of used carrier tape has collected on the take-up spool and the amount of carrier tape still present on the feed spool has become considerably smaller, the tape guide mentioned prevents the unused carrier tape from rubbing against the returning, used carrier tape and against the roll on the take-up spool and, by so doing, avoids damage to the film on the carrier tape and premature separation of the film from the tape. This is particularly important in the case of so-called correction rollers because, to ensure satisfactory operation, the film covering the incorrect characters/symbols has to be applied to the substrate without any cracks or gaps if the area to be corrected is to be completely covered.
The disadvantage of the known adhesive roller lies in the need to provide tape guides between the offwinding point of the feed spool and the applicator element. This is because the carrier tape is kinked fairly sign~cantly in the region of the tape guides and part of the film can separate from the carrier tape.
In conventional dispensers which are not provided with a pivotal applicator element, this disadvantage is of negligible, if any, significance in practice because the film is not exposed to any further stresses. However, if - as in the case of the dispenser according to EP 0 656 308 B1 - the applicator element is turned through a relatively large angle of up to 180°
about its longitudinal axis, the coated carrier tape is correspondingly twisted in the region between the first tape guide and the applicator element. The double stressing of the film by the tape guide and by twisting can lead to cracks in the film layer and to premature separation of parts of the film from the carrier tape.
Accordingly, the problem addressed by the invention was largely to eliminate the danger of damage to the film applied to the carrier tape or _ CA 02318824 2000-07-27 - . , premature separation thereof from the carrier tape in a dispenser of the type mentioned at the beginning.
According to the invention, the solution to this problem in a dispenser of the type mentioned at the beginning is characterized in that the carrier tape is self supporting from the feed spool to the applicator element.
According to the invention, therefore, there are no tape guide elements for the coated carrier tape between the feed spool and the applicator element.
Accordingly, kinking of the carrier tape by a tape guide element - with the adverse effects described above - no longer occurs. The twisting of the carrier tape which occurs during pivoting of the applicator element is not sufficient in itself to damage or prematurely separate the film.
Where the feed spool and the take-up spool are arranged in tandem, another embodiment of the invention is characterized in that the feed spool is situated nearer the applicator element than the take-up spool. In this way, there are a number of possible arrangements where the carrier tape is self supporting from the feed spool to the applicator element because it is not possible for the unused carrier tape to come into contact with the roll on the take-up spool.
However, the invention is not confined to dispensers with spools an-anged in tandem and also encompasses dispensers where the spools are arranged beside one another, i.e. coaxially or substantially coaxially.
A particularly slim and handy version of the dispenser according to the invention is characterized in that the two spools and the applicator element lie substantially in a line and the feed spool is located between the take-up spool and the applicator element.
In addition, in the above-mentioned embodiment where the feed spool and the take-up spool are an-anged in tandem and the feed spool is situated nearer the applicator element than the take-up spool, the film is disposed on the inside of the carrier tape wound onto the feed spool and the two spools rotate in opposite directions in operation. In this way, there is no possibility _ ' 4 whatever of the film of the unused carrier tape coming into contact with the used carrier tape travelling back into the housing. The contra-rotation of the spools in operation is to be found in many standard versions of such dispensers where the spools are directly coupled to one another, for example by gearwheels or a friction clutch.
However, gearwheels with a gearwheel in between may also be provided so that the two spools rotate in the same direction. In this case, it would not matter on which side of the carrier tape the film was disposed because contact between the outgoing carrier tape and the returning carrier tape is in no way possible with spools arranged in tandem. Accordingly, another advantageous embodiment of the invention is characterized in that the two spools rotate in the same direction in operation.
The film applied to the carrier tape can be further protected if the point at which the carrier tape is offwound from the feed spool lies substantially on the pivoting axis of the applicator element. In this case, the unused carrier tape is only stressed by the unavoidable twisting which it undergoes during pivoting of the applicator element, but not additionally by the change in direction from the self-supporting section to the section within the applicator element.
The dispenser according to the invention can be designed as a disposable article or as a refillable item. In the latter case, a gearwheel is associated with each spool, the gearwheels interengage to establish a driving connection between the spools and are disposed within the housing and a replacement cassette containing the two spools and the applicator element is designed to be inserted into the housing. A replacement cassette such as this is particularly environment-friendly because the amount of material it uses is small. In addition, carrier tapes of different width and with different film materials can be used in the same housing.
Although the dispenser according to the invention enables the applicator element to be pivoted through a very Large angle without damaging the film applied to the carrier tape, extremely large pivoting angles should be avoided because the correspondingly heavy twisting of the carrier tape could lead to film damage. In another embodiment, therefore, the applicator element comprises at least one stop co-operating with another stop in order to limit the pivoting angle. The pivoting angle should be limited to a value of at least 90°, preferably to a value of 135° and more preferably to a value of 180°.
Another preferred embodiment designed to prevent the film from being unintentionally applied to an unwanted substrate, for example the clothing of the user, is characterized by the provision of a part which can be moved into at least two positions and which, in the first position, covers the outermost end of the applicator element and, in the second 'position, uncovers this outermost end. When the dispenser is not in use, the part in question can be moved into the first position. To use the dispenser, it is moved into the second position.
The movable part preferably has another function. In this case, it is designed as an actuating element and is rotatably connected to the applicator element for its pivoting movement about the pivot axis.
In one particularly preferred embodiment, the movable part is tubular in shape and at least partly surrounds the applicator element.
One example of embodiment of the invention is described in detail in the following with reference to the accompanying drawings, wherein:

In all the drawings, the same reference numerals have the same meanings and, accordingly, may only be explained once.
The dispenser 1 shown in Figs. 1 and 2, of which the component parts in this example are made of plastic, comprises a housing 33 with a first half 22, a second half 23 and an applicator element 6 partly projecting from the housing, the projecting part of the applicator element 6 being partly situated within the actuating element 26 in the assembled state.
Arranged in the two halves 22, 23 of the housing 33 are a feed spool 2 and a take-up spool 3 for a carrier tape 5. The as yet unused carrier tape is accommodated on the feed spool while the used carrier tape 5 is wound onto to the take-up spool 3. The carrier tape 5 is coated, for example, with a correcting film and is guided from the feed spool 2 out of the housing around the applicator element 6, the film 4 being transfer-ed to a substrate (Figs. 6A to 6C), and finally back into the housing to the take-up spool 3.
The feed spool 2 consists of an annular spool core 13 with a flange 12.
The annular spool core 13 is mounted on a hub 16 consisting of flexible pins 17 and is frictionally held by the pins 17. The pins 17 form part of a gearwheel 18 which is rotatabiy mounted ,through its hub 16 on a ring 20 which projects from the inner wall of the first half 22 of the housing 33 into the interior of the housing and which is integral with that half 22 of the housing.
The take-up spool 3 also consists of an annular spool core 15 with a flange 14 which, in contrast to the flange 12 of the feed spool 2, is in the form of a gearwheel 19. The spool core 15 of the take-up spool 3 is mounted for rotation on a ring 21 which is also integral with the first half 22 of the housing 33 and projects inwards from its inner wall into the housing.
In the assembled state, the gearwheels 18,19 are arranged in such a way that their teeth interengage. Accordingly, when the gearwheel 18 turns through the offwinding of the carrier tape 5 from the feed spool 2, the take-up spool 3 also turns so that the used carrier tape 5 - appropriately guided - is wound onto the take-up spool 3.
In use, the diameter of the roll on the feed spool 2 becomes smaller and the diameter of the roll on the take-up spool 3 larger. To ensure that the carrier tape 5 remains under tension without being overly pulled, the ratio between the rotational speeds of the feed spool 2 and the take-up spool 3 has to be inverted in the same way as the ratio between the respective roll diameters. To this end, a slipping clutch known per se is provided between the spools 2 and 3. In the present example, this slipping clutch consists of the compression joint between the inside of the annular spool core 13 and the flexible elastic pins 17 of the hub 16.
The applicator element 6 projects from the housing 33 through an opening 34 and consists of a flat intermediate part 7 with a tape guide which terminates at an applicator lip 8 with a sharp edge. The intermediate part 7 is arranged within and fixedly connected to a hollow half-cylinder 9. Arranged on the outside of the hollow half-cylinder 9 are annularly encircling, projecting fillets 10 which, in the assembled state of the dispenser 1, engage in grooves 11 on the inside of the opening 34 and are freely movable in relation to those grooves 11. In this way, the applicator element 6 can be pivoted about the axis A A (Figs. 1 and 2) relative to the housing 33. The axis A A runs substantially in the direction of movement of the carrier tape 5 between the spool and the applicator lip 8 and between the applicator lip 8 and the take-up spool 3.
The pivoting movement of the applicator element 6 about the axis A A
is limited in both directions by stops 39 (Figs. 2 and 4) on the inside of the two housing halves 22, 23 and a projection 40 on the outside of the hollow half-cylinder 9 corresponding to the stops 39 (Figs. 2, 3A and 3B). The _ angular interval between the two stops 39 is so large that the pivoting angle of the applicator element 6 can be more than 90°. In the illustrated embodiment, the stops 39 are diametrically opposite one another so that the applicator element 6 can even be pivoted through an angle of 180° and the film 4 applied to the carrier tape 5 can be transferred to the substrate 32 in opposite directions.
According to the invention, the applicator element 6 is mounted for free rotation in the opening 34 of the housing 33. The applicator lip 8 thus always adapts itself automatically to the position of the substrate 32. However, the applicator element 6 may also be wedged in the opening 34 so that friction forces have to be overcome whenever the applicator element 6 is turned relative to the housing 33. To this end, it is of advantage to provide an actuating element 26 co-operating with the applicator element 6. At one end, the actuating element 26 comprises a hollow half-cylinder 27 which, in the assembled state, forms a whole cylinder with the hollow half-cylinder 9 of the applicator element 6 and, in this way, establishes the drive connection between the actuating element 26 and the applicator 6, as is apparent in particular from Figs. 3A and 3B. The actuating element 26 is hollow and, at its other end, has an opening 28 through which the applicator lip 8 of the applicator element 6 can project in the assembled state. By means of the _ CA 02318824 2000-07-27 annular ribbed grip part 29 arranged on the outside, the actuating element 26 and hence the applicator element 6 can readily be turned into the desired position.
In its axially extending cut surtaces 41, the hollow half-cylinder 27 of the actuating element 26 comprises openings 42 in which engage - in the assembled state - projections 43 which are chamfered one side and which project from the axially extending cut surtace 44 of the hollow half-cylinder of the applicator element 6. The cut surfaces 41 of the actuating element 26 are chamfered at their ends so that the actuating element 26 can readily be pushed into the opening 34 of the housing 33, the chamfered ends of the cut surfaces 41 sliding over the chamfered projections 43 of the applicator element 6 until the projections 43 engage in the openings 42. Since the openings 42 are longer axially than the projections 43, the actuating element 26 is axially displaceable relative to the applicator element 6. Accordingly, the actuating element 26 can be axially displaced from the operating position, in which it is pushed into the housing 33 (Figs. 3B and 4) and the applicator lip 8 of the applicator element 8 projects from the opening 28, outwards in the direction of the arrow 38 (Fig. 3B) into the inoperative position (Figs. 3A, and SB) in which the entire applicator lip 8 is situated within the actuating element 26. In this state, the actuating element 26 acts as a protective cap for the applicator lip 8 of the applicator element 6 when the dispenser 1 is not in use. The adhesive or correcting film 4 is thus prevented from being unintentionally transferred from the carrier tape 5 to an unwanted substrate, for example the clothing of the user.
The assembly of the dispenser is explained in the following. To this end, the feed spool 2 is placed on the gearwheel 18 and wedged tight with the hub 16. The carrier tape 5 is guided around the applicator element 6.
The feed spool 2 together with the gearwheel 18 and the take-up spool 3 are fitted onto their respective rings 20, 21 - forming the rotation axes -in the first half 22 of the housing and the applicator element 6 is inserted into the opening 34. The carrier tape 5 is self-supporting between the offwinding point of the feed spool 2 and the intermediate part 7 of the applicator element 6 but is guided over a tape guide pin 35 between the applicator element 6 and the take-up spool 3. Finally, the second half 23 of the housing provided on its inside with projecting pins 24 is fitted onto the first half 22 and wedged in place by insertion of the pins 24 into corresponding openings 25 and wedging therein. Finally, the actuating element 26 is pushed over the applicator element 6 into the opening 34 of the housing 33.
The two halves 22, 23 of the housing 33 each have a depression 31 for the thumb 36 of the (left-handed or right-handed) user. The second half _ 23 of the housing additionally has an opening 30 through which the user is able to tell how much coated carrier tape 5 is still present on the feed spool 2.
The point at which the carrier tape 5 is offwound from the feed spool (the "offwinding point") is substantially colinear with the pivot axis A A of the applicator element 6. According to the invention, there is no tape guide between the feed spool 2 and the applicator element 6 so that the applicator element can be pivoted through a large angle. In the illustrated embodiment, the applicator element 6 can be pivoted without difficulty through about 180°
so that the dispenser 1 can be used in two opposite directions, i.e. to the right (Fig. 6A) and to the left (Fig. 6C), and is therefore suitable both for right-handed and for left-handed users. In addition, the dispenser 1 can be used in any position lying between those two positions, as shown for example in Fig. 6B.
In the illustrated embodiment, the carrier tape 5 is coated with a correcting film 4 with which handwritten or printed characterslsymbols can be covered.
In the illustrated embodiment, the danger of the film 4 applied to an -exceptionally - loose carrier tape 5 rubbing on parts arranged within the housing 33 and thus suffering damage is eliminated on the one hand by _ CA 02318824 2000-07-27 positioning the feed spool 2 very close to the applicator element 6 and, on the other hand, by winding the carrier tape 5 onto the feed spool 2 in such a way that the film 4 is directed towards the spool core 13 of the feed spool 2.
The invention is not of course confined to this embodiment. Thus, according to the invention, the two spools 2, 3 and the applicator element 6 may be parts of a replaceable cassette inserted into the housing 33. in this case, the gearwheels 18,19 can be fixedly arranged in one of the two halves of the housing 33. In addition, the two spools 2, 3 may be arranged beside one another and not - as in the illustrated embodiment - one behind the other.

There are various known hand-held dispensers for transferring a film from a carrier tape to a substrate. The film disposed on the ribbon-like carrier tape can be an adhesive film or a masking composition for covering incorrect characterslsymbols applied to paper.

0 656 308 B1. Two spools rotating in opposite directions are disposed in a housing, one forming the feed spool and the other the take-up spool.

In all the drawings, the same reference numerals have the same meanings and, accordingly, may only be explained once.
The dispenser 1 shown in Figs. 1 and 2, of which the component parts in this example are made of plastic, comprises a housing 33 with a first half 22, a second half 23 and an applicator element 6 partly projecting from the housing, the projecting part of the applicator element 6 being partly situated within the actuating element 26 in the assembled state.
Arranged in the two halves 22, 23 of the housing 33 are a feed spool 2 and a take-up spool 3 for a carrier tape 5. The as yet unused carrier tape is accommodated on the feed spool while the used carrier tape 5 is wound onto to the take-up spool 3. The carrier tape 5 is coated, for example, with a correcting film and is guided from the feed spool 2 out of the housing around the applicator element 6, the film 4 being transfer-ed to a substrate (Figs. 6A to 6C), and finally back into the housing to the take-up spool 3.
The feed spool 2 consists of an annular spool core 13 with a flange 12.
The annular spool core 13 is mounted on a hub 16 consisting of flexible pins 17 and is frictionally held by the pins 17. The pins 17 form part of a gearwheel 18 which is rotatabiy mounted ,through its hub 16 on a ring 20 which projects from the inner wall of the first half 22 of the housing 33 into the interior of the housing and which is integral with that half 22 of the housing.
The take-up spool 3 also consists of an annular spool core 15 with a flange 14 which, in contrast to the flange 12 of the feed spool 2, is in the form of a gearwheel 19. The spool core 15 of the take-up spool 3 is mounted for rotation on a ring 21 which is also integral with the first half 22 of the housing 33 and projects inwards from its inner wall into the housing.
In the assembled state, the gearwheels 18,19 are arranged in such a way that their teeth interengage. Accordingly, when the gearwheel 18 turns through the offwinding of the carrier tape 5 from the feed spool 2, the take-up spool 3 also turns so that the used carrier tape 5 - appropriately guided - is wound onto the take-up spool 3.
In use, the diameter of the roll on the feed spool 2 becomes smaller and the diameter of the roll on the take-up spool 3 larger. To ensure that the carrier tape 5 remains under tension without being overly pulled, the ratio between the rotational speeds of the feed spool 2 and the take-up spool 3 has to be inverted in the same way as the ratio between the respective roll diameters. To this end, a slipping clutch known per se is provided between the spools 2 and 3. In the present example, this slipping clutch consists of the compression joint between the inside of the annular spool core 13 and the flexible elastic pins 17 of the hub 16.
The applicator element 6 projects from the housing 33 through an opening 34 and consists of a flat intermediate part 7 with a tape guide which terminates at an applicator lip 8 with a sharp edge. The intermediate part 7 is arranged within and fixedly connected to a hollow half-cylinder 9. Arranged on the outside of the hollow half-cylinder 9 are annularly encircling, projecting fillets 10 which, in the assembled state of the dispenser 1, engage in grooves 11 on the inside of the opening 34 and are freely movable in relation to those grooves 11. In this way, the applicator element 6 can be pivoted about the axis A A (Figs. 1 and 2) relative to the housing 33. The axis A A runs substantially in the direction of movement of the carrier tape 5 between the spool and the applicator lip 8 and between the applicator lip 8 and the take-up spool 3.
The pivoting movement of the applicator element 6 about the axis A A
is limited in both directions by stops 39 (Figs. 2 and 4) on the inside of the two housing halves 22, 23 and a projection 40 on the outside of the hollow half-cylinder 9 corresponding to the stops 39 (Figs. 2, 3A and 3B). The _ angular interval between the two stops 39 is so large that the pivoting angle of the applicator element 6 can be more than 90°. In the illustrated embodiment, the stops 39 are diametrically opposite one another so that the applicator element 6 can even be pivoted through an angle of 180° and the film 4 applied to the carrier tape 5 can be transferred to the substrate 32 in opposite directions.
According to the invention, the applicator element 6 is mounted for free rotation in the opening 34 of the housing 33. The applicator lip 8 thus always adapts itself automatically to the position of the substrate 32. However, the applicator element 6 may also be wedged in the opening 34 so that friction forces have to be overcome whenever the applicator element 6 is turned relative to the housing 33. To this end, it is of advantage to provide an actuating element 26 co-operating with the applicator element 6. At one end, the actuating element 26 comprises a hollow half-cylinder 27 which, in the assembled state, forms a whole cylinder with the hollow half-cylinder 9 of the applicator element 6 and, in this way, establishes the drive connection between the actuating element 26 and the applicator 6, as is apparent in particular from Figs. 3A and 3B. The actuating element 26 is hollow and, at its other end, has an opening 28 through which the applicator lip 8 of the applicator element 6 can project in the assembled state. By means of the _ CA 02318824 2000-07-27 annular ribbed grip part 29 arranged on the outside, the actuating element 26 and hence the applicator element 6 can readily be turned into the desired position.
In its axially extending cut surtaces 41, the hollow half-cylinder 27 of the actuating element 26 comprises openings 42 in which engage - in the assembled state - projections 43 which are chamfered one side and which project from the axially extending cut surtace 44 of the hollow half-cylinder of the applicator element 6. The cut surfaces 41 of the actuating element 26 are chamfered at their ends so that the actuating element 26 can readily be pushed into the opening 34 of the housing 33, the chamfered ends of the cut surfaces 41 sliding over the chamfered projections 43 of the applicator element 6 until the projections 43 engage in the openings 42. Since the openings 42 are longer axially than the projections 43, the actuating element 26 is axially displaceable relative to the applicator element 6. Accordingly, the actuating element 26 can be axially displaced from the operating position, in which it is pushed into the housing 33 (Figs. 3B and 4) and the applicator lip 8 of the applicator element 8 projects from the opening 28, outwards in the direction of the arrow 38 (Fig. 3B) into the inoperative position (Figs. 3A, and SB) in which the entire applicator lip 8 is situated within the actuating element 26. In this state, the actuating element 26 acts as a protective cap for the applicator lip 8 of the applicator element 6 when the dispenser 1 is not in use. The adhesive or correcting film 4 is thus prevented from being unintentionally transferred from the carrier tape 5 to an unwanted substrate, for example the clothing of the user.
The assembly of the dispenser is explained in the following. To this end, the feed spool 2 is placed on the gearwheel 18 and wedged tight with the hub 16. The carrier tape 5 is guided around the applicator element 6.
The feed spool 2 together with the gearwheel 18 and the take-up spool 3 are fitted onto their respective rings 20, 21 - forming the rotation axes -in the first half 22 of the housing and the applicator element 6 is inserted into the opening 34. The carrier tape 5 is self-supporting between the offwinding point of the feed spool 2 and the intermediate part 7 of the applicator element 6 but is guided over a tape guide pin 35 between the applicator element 6 and the take-up spool 3. Finally, the second half 23 of the housing provided on its inside with projecting pins 24 is fitted onto the first half 22 and wedged in place by insertion of the pins 24 into corresponding openings 25 and wedging therein. Finally, the actuating element 26 is pushed over the applicator element 6 into the opening 34 of the housing 33.
The two halves 22, 23 of the housing 33 each have a depression 31 for the thumb 36 of the (left-handed or right-handed) user. The second half _ 23 of the housing additionally has an opening 30 through which the user is able to tell how much coated carrier tape 5 is still present on the feed spool 2.
The point at which the carrier tape 5 is offwound from the feed spool (the "offwinding point") is substantially colinear with the pivot axis A A of the applicator element 6. According to the invention, there is no tape guide between the feed spool 2 and the applicator element 6 so that the applicator element can be pivoted through a large angle. In the illustrated embodiment, the applicator element 6 can be pivoted without difficulty through about 180°
so that the dispenser 1 can be used in two opposite directions, i.e. to the right (Fig. 6A) and to the left (Fig. 6C), and is therefore suitable both for right-handed and for left-handed users. In addition, the dispenser 1 can be used in any position lying between those two positions, as shown for example in Fig. 6B.
In the illustrated embodiment, the carrier tape 5 is coated with a correcting film 4 with which handwritten or printed characterslsymbols can be covered.
In the illustrated embodiment, the danger of the film 4 applied to an -exceptionally - loose carrier tape 5 rubbing on parts arranged within the housing 33 and thus suffering damage is eliminated on the one hand by _ CA 02318824 2000-07-27 positioning the feed spool 2 very close to the applicator element 6 and, on the other hand, by winding the carrier tape 5 onto the feed spool 2 in such a way that the film 4 is directed towards the spool core 13 of the feed spool 2.
The invention is not of course confined to this embodiment. Thus, according to the invention, the two spools 2, 3 and the applicator element 6 may be parts of a replaceable cassette inserted into the housing 33. in this case, the gearwheels 18,19 can be fixedly arranged in one of the two halves of the housing 33. In addition, the two spools 2, 3 may be arranged beside one another and not - as in the illustrated embodiment - one behind the other.
