Description

[0001] The present invention relates to a device for the precise application of sealing tape, in particular for applying sealing tape that is unrolled from a roll. Furthermore, the invention also relates to a kit of parts comprising the device for applying sealing tape, a roll holder for unrolled sealing tape, and a method for the precise application of sealing tape.

[0002] It is well known that sealing tape is used in drywall construction for sound insulation and noise insulation. Since metal profiles are known to be used in drywall construction to hold substructures for ceilings or wall elements for walls, and these metal profiles also need to be covered with sealing tape to minimize noise transmission, there is a special sealing tape that is applied to the metal profiles, e.g., U-profiles or CD profiles.

[0003] The sealing tape used for noise reduction is usually purchased in a roll. To apply the sealing tape to a metal profile, it is unrolled by hand and adhered piece by piece to the metal profile. It is important to ensure that the tape is applied evenly to the profiles to ensure a precise fit. With metal profiles typically several meters long, applying the sealing tape to the profiles is time-consuming, as it requires millimeter-precise work and adjustments as necessary to ensure the metal profiles are evenly covered with sealing tape along their entire length.

[0004] It would therefore be desirable to have a device or auxiliary tool for applying sealing tape that facilitates the application of the tape and / or reduces the time required for this. However, such a device or auxiliary tool is not known in the prior art.

[0010] It is therefore the object of the present invention to provide a device for the precise application of sealing tape, which is characterized in particular by a high level of user-friendliness, which is expressed in simple handling and a high time saving for the application of sealing tape.

[0011] A further object of the present invention is to provide an alternative method for applying sealing tape, which is characterized by high accuracy and a low expenditure of time. General description of the invention

[0012] The invention solves this problem with the features of the claims and in particular with a device for the precise application of sealing tape, comprising a main surface extending in a plane, which is connected on a first side to a first contact surface, wherein the main surface and the first contact surface are arranged at a 90° angle to one another, wherein the main surface is connected on a second side opposite the first side at a 90° angle to a second contact surface, wherein the second contact surface is displaceable in the direction of the first contact surface and parallel to it and can be fixed in different positions with different distances from the first contact surface.

[0013] Because the second contact surface is movable relative to the first contact surface and can be fixed in various positions at different distances from the first contact surface, the distance between the first contact surface and the second contact surface can be easily adjusted to accommodate adhesive tapes of different widths. The same device is therefore suitable for applying adhesive tapes of different widths by simply adjusting the distance between the first contact surface and the second contact surface to the respective width of the sealing tape to be applied.

[0014] The displaceability of the second contact surface is achieved in that the main surface of the device according to the invention has two parallel recesses which are spaced apart from one another and each run perpendicular to the first contact surface and the second contact surface, wherein a fastening means is displaceably arranged in each recess, which is in engagement with an attachment piece arranged on the second contact surface and can be releasably fixed to the attachment piece arranged on the second contact surface in any position within the recess.

[0015] According to the invention, the main surface of the device according to the invention comprises two spaced-apart partial surfaces, each partial surface containing one of the aforementioned recesses, which extend perpendicular to the first contact surface and the second contact surface and in each of which a fastening means is displaceably arranged, which engages with an attachment piece arranged on the second contact surface and can be releasably fixed to it. The advantage of a main surface that comprises or consists of two spaced-apart partial surfaces lies in the lower weight of the device and the resulting lower material requirements for its manufacture.

[0016] According to one embodiment, the device according to the invention is made of plastic, in particular PLA. This material is particularly suitable for manufacturing the device using 3D printing. In this embodiment, no excess material is even generated during production, since the recesses in the partial surfaces are incorporated in the 3D printing process from the outset and do not need to be subsequently removed from the material. Alternatively, but less preferably, the device according to the invention can also be made of metal, for example, aluminum.

[0017] The fastening means with which the second contact surface can be fixed in its position can be any suitable fastening means, in particular locking screws which engage in sliding blocks guided in the recesses.

[0018] Advantageously, the device according to the invention has a handle and can thus be conveniently moved manually along an object to be covered with sealing tape. The handle can be arranged, for example, on the first contact surface, on the second contact surface, or on the attachment piece connected to the second contact surface.

[0019] According to a preferred embodiment, the main surface of the device according to the invention for precisely applying sealing tape to one or both partial surfaces has a scale that indicates the distance between the first contact surface and the second contact surface in the respective position of the second contact surface. This distance corresponds to the width of the sealing tape to be applied and is adjustable, for example, to 30-100 mm, in particular to 50-100 mm.

[0020] The invention further relates to a kit of parts. This comprises a device according to the invention as described above and a roll holder for sealing tape rolled up into a roll. The roll holder has a threaded rod with a handle at one end and a removable threaded nut on the side opposite the handle, which can be screwed continuously onto the threaded rod in the direction of the handle. A roll of sealing tape can therefore be placed on the threaded rod and fixed in position by screwing on the threaded nut until it makes contact with the roll. The sealing tape can have any width, corresponding at most to the length of the threaded rod less a few millimeters for the engagement of the threaded nut with the threaded rod.

[0021] Furthermore, the invention also relates to a method for the precise application of sealing tape to an object to be bonded, which comprises the following steps: - Arranging a roll of sealing tape on a roll holder which has a threaded rod with a handle at one end and which has a removable threaded nut on the side opposite the handle, which can be screwed continuously onto the threaded rod in the direction of the handle by placing the roll of sealing tape on the threaded rod and pushing it as far as possible towards the handle and fixing it in position by screwing on the threaded nut until it makes contact with the roll; - Unroll the sealing tape from the roll and attach it to the object to be sealed; - Adjusting a device according to the invention described above for the exact application of sealing tape to the respective width of the sealing tape by adjusting the distance between the first contact surface and the second contact surface of the device so that it corresponds to the width of the sealing tape; - arranging the device on the sealing tape attached to the object to be glued, by arranging the first contact surface and the second contact surface on opposite long sides of the object to be glued; - Fixing the sealing tape on the object to be glued by guiding the device along the longitudinal direction of the object to be glued.

[0022] The device used in the method according to the invention for the precise application of sealing tape can have all the features described above with regard to the device according to the invention as such. Features from the above description of the device can therefore also be used to further characterize the method, and vice versa.

[0023] Finally, the invention also relates to the use of a device according to the invention for the precise application of sealing tape for applying sealing tape to an elongated object, in particular a metal profile. Detailed description of the invention
