Abstract

The invention relates to a hand-held device 100 for unwinding an adhesive tape 41 which is located in the form of an Archimedean spiral on a roll 4 and has a double-sidedly adhesively furnished carrier, at least one of the two adhesive sides of the carrier being lined with a release material 42, consisting of a handle 1 which is disposed on a retaining plate 2, a holder 21, mounted rotatably on the retaining plate 2, for the roll 4 of the adhesive tape 41, a take-off apparatus 22, connected to the retaining plate 2, and more particularly in the form of a roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 22, and the adhesive tape 41 is taken off from the roll 4 during the dispensing operation, a take-off apparatus 23, connected to the retaining plate 2, and more particularly in the form of a roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 23, and the release material 42 is taken off from the adhesive tape 42 during the dispensing operation, a contact roll 24, mounted rotatably on the retaining plate 2, which during the dispensing operation brings the adhesive tape 41 into contact with the substrate, and a release material accommodation roll 25, mounted rotatably on the retaining plate 2, which accommodates the release material 42 after it has been taken off from the adhesive tape 41, and which is non-positively connected to the holder 21, so that movement of the holder 21 sets the release material accommodation roll 25 in rotation.

Claims

1. A hand-held device for unwinding an adhesive tape formed in shape of an Archimedean spiral on a roll and having a double-sidedly adhesive carrier, at least one of two adhesive sides of the carrier being lined with a release material,

the device comprises

a handle 1,

a retaining plate 2, the handle being disposed on the retaining plate,

a holder 21, mounted rotatably on the retaining plate 2, acconmmodating the roll 4 of the adhesive tape 41,

a take-off apparatus 22, connected to the retaining plate 2, and in form of the roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 22, and the adhesive tape 41 is taken off from the roll 4 during the dispensing operation,

a take-off apparatus 23, connected to the retaining plate 2, and in the form of a roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 23, and the release material 42 is taken off from the adhesive tape 41 during the dispensing operation,

a contact roll 24, mounted rotatably on the retaining plate 2, which during the dispensing operation brings the adhesive tape 41 into contact with a substrate, and a release material accommodation roll 25, mounted rotatably on the retaining plate 2, which accommodates the release material 42 after it has been taken off from the adhesive tape 41, and which is non-positively connected to the holder 21, so that movement of the holder 21 sets the release material accommodation roll 25 in rotation.

2. The hand-held device according to claim 1, wherein

the non-positive connection between the release material accommodation roll 25 and the holder 21 is made via a belt 30 which is guided via an axes of release material accommodation roll 25 and the holder 21.

3. The hand-held device according to claim 2, wherein the belt 30 is a rubber O-ring.

4. The hand-held device according to claim 1, wherein an adjustable brake is present in the holder 21 for the roll 4 of the adhesive tape 41.

5. The hand-held device according to claim 1, wherein the take-off apparatus 22 is connected pivotably to the retaining plate 2.

6. The hand-held device according to claim 1, wherein the take-off of the adhesive tape 41 from the roll takes place via the take-off apparatus 22 such that the take-off angle is at least 180°

.

7. The hand-held device according to claim 1, wherein between take-off apparatus 23 and the contact roll 24 there is a parting unit 52 which is capable of severing the adhesive tape.

8. The hand-held device according to claim 7, wherein the parting unit 52 comprises two blades which are capable of being brought together in scissor-like fashion for the parting operation.

9. The hand-held device according to claim 8, wherein the parting operation in the parting unit 52 is initiated at the handle 1 via an apparatus 53.

10. The hand-held device according to claim 1, wherein the take-off of the release material 42 from the adhesive tape 41 takes place via the take-off apparatus 23 such that the take-off angle is at least 90°

.

11. The hand-held device according to claim 1, wherein the release material has two end faces and wherein on at least one of the two end faces of the release material accommodation roll 25 there is a disc provided having a diameter greater than the diameter of the release material accommodation roll 25.

12. The hand-held device according to claim 1, wherein the handle 1 is accommodated in mirror-image form on the retaining plate 2.

13. The hand-held device according to claim 1, wherein the release material 42 has a slit extending in longitudinal direction.

14. The hand-held device according to claim 1, wherein the adhesive tape 41 which is located in the form of an Archimedean spiral on a roll 4, is composed of a double-sidedly adhesive carrier and at least one of the two adhesive sides of the carrier being lined with a release material 42.

15. The hand-held device according to claim 4, wherein the adjustable brake is a friction brake.

16. The hand-held device according to claim 5, wherein the take-off apparatus 22 is connected pivotably to the retaining plate 2 more particularly via a frame 51.
