Description

The invention relates to an adhesive tape dispenser.

Adhesive tape dispensers are sufficiently known from the prior art.

The EP 2 966 019 A2 discloses an adhesive tape dispenser for a roll of adhesive tape with a core element, the dispenser essentially consisting of a carrier unit. The document also discloses a metal bracket which presses a section of adhesive tape onto an application roller.

A problem with the prior art is that adhesive tape can peel off too early from the adhesive tape dispenser. Here it can happen that detached adhesive tape sections are connected again to the adhesive tape roll, which makes it difficult to detach them again. Adhesive tape sections can also be knotted, in which case, in view of the adhesive effect of the adhesive tape, untying is not possible and / or very time-consuming. A further problem can be the tearing of the adhesive tape if the forces acting on the adhesive tape become too strong.

Another problem arises from noise pollution in the workplace. Tape dispensers can be very noisy when applying tape. Since professional adhesive tape dispensers are often used for hours and several days a week, this high volume can be a burden for the employee, and in extreme cases it can also affect the employee's health. It is therefore advantageous if the adhesive tape dispenser applies adhesive tape with as little noise as possible.

The object of the present invention was therefore to overcome the disadvantages of the prior art and in particular to provide an adhesive tape dispenser with which adhesive tape can be applied particularly reliably, comfortably and with little noise.

The object is achieved by an adhesive tape dispenser comprising a handle, a receiving device with a preferably pivotable and / or rotatable one pivotable and rotatable bearing for a roll of adhesive tape, an application device with an, in particular rotatable, application roller, a rotationally fixed friction bridge with a bridge sliding surface and a deflection bead, in particular a deflection bead with a transverse elevation, preferably a transverse curvature, the adhesive tape dispenser being designed and set up so that a Adhesive tape section of a roll of adhesive tape present on the bearing, in particular rotatably mounted, slides or can slide over the bridge sliding surface or at least over the deflecting bead, in particular over the transverse elevation or deflecting contact surface of the deflecting bead, and optionally then over the bridge sliding surface, when it unrolls over the bridge sliding surface, before it hits the application device meets. The handle can preferably be designed as a tangential or radial handle. The roll of adhesive tape can optionally be part of the adhesive tape dispenser, but preference is given to an adhesive tape dispenser without an adhesive tape roll, which can, however, receive an adhesive tape roll in the manner described above.

Surprisingly, the friction bridge with the deflecting bead, in particular with the transverse elevation or the deflecting contact surface of the deflecting bead, and in particular also the bridge sliding surface, improves the application of adhesive tape sections quite considerably. It is assumed - without being bound by a theory - that attractive interactions act between the deflecting bead, in particular the transverse elevation or the deflecting contact surface of the deflecting bead, and in particular also the bridge sliding surface and the adhesive tape section placed on it, which increase the likelihood of inadvertent detachment of the adhering adhesive tape section to decrease. Among other things, these can also be Van der Waals forces. However, it is assumed that an electrostatic attraction between the friction-generating deflecting bead, in particular the transverse elevation or the deflecting contact surface of the deflecting bead, and / or the bridge sliding surface and the adhesive tape section could play a not inconsiderable role. It is also particularly surprising that these attractive forces beyond the deflecting bead, in particular the transverse elevation or the deflecting contact surface of the deflecting bead, and in particular also the bridge sliding surface, can bring about improved adhesion, which may be related to the fact that the deflecting bead and in particular the bridge sliding surface are electrostatically charged by friction can produce, which continues beyond the deflection bead or bridge sliding surface. Regardless of the actual mechanism of action, the friction bridge according to the invention considerably improves the applicability of the adhesive tape and reduces the probability of the adhesive tape becoming knotted. In the case of the adhesive tape dispenser according to the invention, the bridge sliding surface preferably functions as a sliding or contact surface for the adhesive tape sliding along it, preferably its non-adhesive back, but can also only or additionally serve as a contact surface. In a possible embodiment variant, after leaving the deflection bead, when it is guided past the so-called bridge sliding surface, or only in sections, does not come into contact with the bridge sliding surface. In these embodiments, the bridge sliding surface can also be referred to simply as the bridge surface.

The object is further achieved by an adhesive tape dispenser comprising a handle in the form of a radial handle, a receiving device with a, in particular pivotable and / or rotatable, bearing, in particular a central bearing, for an adhesive tape roll, an application device with an, in particular rotatable, application roller, the Radial handle has a longitudinal axis, the longitudinal axis, in particular the radial handle, and the application roller being on opposite sides of an intermediate plane, the intermediate plane being arranged parallel to the longitudinal axis of the radial handle and the bearing axis of the bearing, in particular the central bearing, in a first storage position in the intermediate plane and / or wherein the application roller and the bearing, in particular the central bearing, are located on the same side with respect to the longitudinal axis when a cross section is viewed orthogonally to the bearing axis. The intermediate level is a level to be constructed hypothetically and not, for example, an actual device object of the adhesive tape dispenser device according to the invention. Optionally, the adhesive tape dispenser also in this embodiment comprises a rotationally fixed friction bridge with a bridge sliding surface and a deflection bead, the adhesive tape dispenser being designed and set up in such a way that an adhesive tape section of an adhesive tape roll present on the bearing, in particular rotatably mounted, when rolling over the deflection bead and possibly also slides or can slide over the bridge sliding surface before it hits the application device.

The radial handle allows a particularly compact design if its longitudinal axis is arranged as described above. Here, the receiving device and the application roller are preferably on the same side of the longitudinal axis.

The receiving device preferably also comprises a mechanism in order to pivot the bearing, in particular the central bearing, out of the first storage position into a second storage position. For this purpose, the bearing is preferably attached to a pivotable swivel arm. The bearing is preferably rotatable and pivotable, in particular rotatable about its own bearing axis and pivotable by pivoting the swivel arm about a swivel arm axis, particularly preferably the position of the bearing axis from deviates from the position of the pivot arm axis and / or wherein said axes are essentially parallel. The bearing, in particular the central bearing, is preferably preloaded in order to move from the first to the second bearing position. If the tape roll has a lot of tape when using the tape dispenser, the bearing will be at or near the first storage position and as the amount of tape on the tape roll decreases, the bearing will automatically move closer to the second storage position. This ensures that the friction bridge is always positioned close to the roll of adhesive tape. Insofar as reference is made to the position of the bearing in this disclosure, the first bearing position is preferably meant, unless the context indicates otherwise. The first storage position is preferably a position which is located in the center of a cylindrical housing for the roll of adhesive tape.

A "handle" within the meaning of the present invention can take various forms. Tangential and radial handles have proven particularly useful. With the radial handle, the handle points with its longitudinal axis in the direction of the bearing, in particular in the first bearing position. The longitudinal axis of a radial handle does not necessarily have to lead directly through the bearing in the first storage position and / or the bearing axis in the first storage position, but preferably close past this, in particular not more than 3 cm, particularly preferably not more than 2 cm, spaced from the bearing and / or the bearing axis in the first bearing position, where the distance between the longitudinal axis and said bearing or said bearing axis in the first bearing position is shortest. In the case of the radial handle, it is preferably provided that the shortest distance between the longitudinal axis and the bearing is present in the first bearing position on the other side of the radial handle. In the case of a tangential handle, however, the handle with its longitudinal axis does not point to the bearing, in particular in the first and second bearing position. Instead, the longitudinal axis of the handle is further away from the bearing and / or the bearing axis than with the radial handle, in particular also where the distance between the longitudinal axis and said bearing or said bearing axis is shortest, more than 3 cm, in particular more than 4 cm, particularly preferably more than 5 cm apart, especially in the first and / or second storage position. In the case of the tangential handle, it is preferably provided that the shortest distance between the longitudinal axis and the bearing, in particular in the first bearing position, is present at a point on the longitudinal axis within the tangential handle. While the longitudinal axis of a radial handle preferably leads through an area in which the roll of adhesive tape is present in the case of the generic use, this is usually not the case with the tangential handle. The longitudinal axis of a tangential handle does not usually come close to the roll of adhesive tape in the generic use, in particular has a minimum distance of 3 cm from the outer area the roll of tape. The longitudinal axis of the handle can also be referred to as the handle axis. It is preferably the central axis of the handle which leads directly through the handle along its length. Both tangential and radial handles can have a cylindrical basic shape, in which the cross-section is mostly not round, but elliptical. Tangential and radial handles are preferably constructed linearly and not curved.

An "adhesive tape section" within the meaning of the present invention can be connected to the roll of adhesive tape, but is preferably no longer attached radially to the core of the roll of adhesive tape, but detached, but preferably still connected at the end to the remaining roll of adhesive tape. It is therefore an adhesive tape section which protrudes completely or partially from the adhesive tape roll and which is connected to the adhesive tape roll at the end and / or in one piece if it has not yet been cut off. The adhesive tape section usually comprises an adhesive adhesive tape side and an opposing non-adhesive adhesive tape side. This is usually achieved by coating the adhesive tape with an adhesive layer on only one side. After applying the adhesive tape section with the adhesive tape dispenser, i. After the section of adhesive tape has been applied to a surface, it is usually cut off and a further section of adhesive tape can be applied. Said further adhesive tape section has already been completely or partially detached from the adhesive tape at the time of cutting. It should be pointed out that the roll of adhesive tape and the section of adhesive tape are only optional components of the adhesive tape dispenser and that an adhesive tape dispenser without a roll of adhesive tape is also claimed.

In the context of the present invention, "non-rotatably" means that the corresponding element is not attached in a rotatable manner, for example connected in one piece with it or glued or screwed on. Of course, the tape dispenser can be turned as a whole by a user, and so can the non-rotating elements. What is meant is that a rotationally fixed element does not rotate with respect to the main body of the rest of the adhesive tape dispenser, in particular not with respect to the handle or possibly the housing. The reference system is therefore the adhesive tape dispenser itself, for example also the handle and possibly the housing of the adhesive tape dispenser. In contrast to a rotationally fixed element, a rotatable element is rotatably connected to the rest of the adhesive tape dispenser. The corresponding element can also preferably not perform any partial rotational and / or pivoting movement with respect to the reference system. A pivotable element is to be understood analogously with the same reference system.

The adhesive tape dispenser is preferably designed for an adhesive tape with an adhesive tape width and the deflection bead comprises a deflection contact surface which is less wide than the adhesive tape width of the adhesive tape, the adhesive tape section of the adhesive tape having adhesive tape edges and, when the adhesive tape dispenser is used in the generic manner, when sliding over the deflection bead with its adhesive tape is spaced apart from the deflection contact surface, in particular spaced apart from the deflection bead. Preferably said deflecting contact surface comprises. This reduces the noise emission.

The adhesive tape dispenser is preferably designed for an adhesive tape with an adhesive tape width of at least 47 mm, the deflecting contact surface having an adhesive tape width of less than 43 mm, in particular less than 40 mm. In some configurations, the adhesive tape dispenser is designed for an adhesive tape with an adhesive tape width of 47 to 51 mm, the deflecting contact surface having a contact surface length of less than 43 mm, in particular less than 40 mm. In some embodiments, the deflection bead is designed so that a polyvinyl chloride packaging tape section of a polyvinyl chloride packaging tape roll with an adhesive tape width of 48 to 50 mm runs along said deflection bead in such a way that the edges of the polyvinyl chloride packaging tape section do not contact the deflection bead, in particular the friction bridge on the deflection bead do not contact. In one embodiment, the adhesive tape dispenser is designed for an adhesive tape with an adhesive tape width of 37 to 51 mm, the deflecting contact surface having a contact surface length of less than 37 mm, in particular less than 35 mm. The contact surface length is preferably determined orthogonally to the direction in which the adhesive tape section slides over the deflection bead and in particular also over the bridge sliding surface.

In some configurations, the deflecting bead comprises a transverse elevation, in particular a transverse arch. It has been shown that the noise when stripping off the roll of adhesive tape is reduced by the transverse elevation, in particular the transverse curvature. Without being bound to a theory, it is assumed that the adhesive tape edges of the adhesive tape vibrate on contact and this vibration does not occur to the same extent if a transverse elevation, in particular transverse arching, prevents said contact at the deflection bead. The vibration can generate noise in a high frequency range.

The deflecting bead preferably comprises said transverse elevation, the transverse elevation being designed and set up to distance the adhesive tape section at the edge from the deflecting bead, while the adhesive tape section contacts the transverse elevation away from the adhesive tape edges. It is preferably provided that the transverse elevation, in particular Transverse curvature, in the generic use, the edges of the adhesive tape section of an adhesive tape roll with an adhesive tape width of 48 mm to 50 mm spaced from the deflecting bead.

The deflecting bead preferably comprises a deflecting contact surface with which the adhesive tape section is in contact when the adhesive tape dispenser is used in accordance with the generic type for applying adhesive tape. In some embodiments, the adhesive tape edges of the adhesive tape are not in contact with said deflecting contact surface, in particular with the deflecting bead, when the adhesive tape dispenser is used for the application of adhesive tape. In a particularly expedient embodiment, the deflection bead is in one piece with the bridge sliding surface or the element which forms the bridge sliding surface. The deflecting bead and the bridge sliding surface are preferably an integral part of the friction bridge.

Preferably, the transverse elevation, in particular at a distance from the friction bridge sides, has a transverse elevation maximum at which the adhesive tape section contacts, while the transverse elevation beyond the transverse elevation maximum, in particular two or more transverse elevation minima at the edge, to which the adhesive tape section, in particular the adhesive tape edges of the adhesive tape section, has generic use of the adhesive tape section for applying adhesive tape not contacted.

The transverse elevation preferably extends between opposing friction bridge sides of the friction bridge. In some configurations, the transverse elevation extends from one or from the direction of a first friction bridge side to or in the direction of a second friction bridge side. The transverse elevation preferably has a transverse elevation maximum which is present between and spaced apart from the friction bridge sides, in particular spaced apart centrally between the friction bridge sides. In one embodiment, the transverse elevation spans a polygonal or continuous arc from the first to the second friction bridge side.

The transverse elevation can be designed as a transverse arch. Alternatively or additionally, a polygonally shaped transverse elevation is also conceivable. In some configurations, the polygonally shaped transverse elevation has a cross section in which it has two legs which comprise transverse elevation minima and a linear connecting line between the limbs which comprises the transverse elevation maximum.

The transverse elevation preferably has at least one cross section which extends orthogonally to the running direction of the adhesive tape section on the transverse elevation and / or to the deflecting slide surface, the transverse elevation being visible in said cross section as a raised and / or curved contour. Alternatively or in addition, the transverse elevation has at least one cross section which extends parallel to the bridge sliding surface, the transverse elevation being visible in said cross section as a raised and / or curved contour. If the deflection curvature does not have a transverse elevation, it can be provided that the deflection curvature in said cross sections is not recognizable as a raised and / or curved contour, but rather as a straight line.

The adhesive tape dispenser comprises a receiving device. In one embodiment, the receiving device can comprise a carrier plate, a closed housing or a semi-closed housing. The housing is preferably designed and set up to receive the roll of adhesive tape and possibly also to hold the cutting knife and the application roller. A closed or half-open housing with a cylindrical recess for a roll of adhesive tape is particularly preferred. In one embodiment, the cutting knife is detachably connected to the receiving device, in particular the housing, preferably wherein no tools are required to release the cutting knife. A clamping mechanism has proven suitable, for example.

In some embodiments, it is provided that the adhesive tape section, after being detached from the adhesive tape roll, is guided with the adhesive side over the application roller and / or the friction bridge in a contact-free manner, in particular slides over these in contact with the non-adhesive side. The receiving device preferably does not make contact with an adhesive tape, in particular the adhesive tape section, in the generic use on the adhesive side, but only on the non-adhesive side.

It is particularly preferred if the receiving device. In particular, the friction bridge and / or application roller is designed and set up to adhere to the non-adhesive side of the adhesive tape, in particular to the non-adhesive side of the adhesive tape section. The adhesion can be based, for example, on van der Wall's forces and / or electrostatic attractive forces. Unlike the adhesive side, however, no adhesive is provided for adhesion. Metal brackets are also known from the prior art, which rest on the adhesive side and prevent the adhesive tape from peeling off. However, this has the disadvantage that the friction is increased considerably. Surprisingly, such metal brackets can be dispensed with in the present invention.

The receiving device comprises a bearing for a roll of adhesive tape. The bearing is preferably completely or partially rotatable, so that adhesive tape sections can be unrolled from the adhesive tape roll. In principle, it is also conceivable that the roll of adhesive tape comprises a rotational bearing and is applied to a rotationally fixed bearing of the adhesive tape dispenser. In any case, it is preferred if a roll of adhesive tape connected to the bearing is rotatable, in particular rotatable about a bearing axis.

Preferably the warehouse of the present invention is configured as a central warehouse, i. in the case of the generic fastening of a roll of adhesive tape on the bearing, the bearing is arranged centrally with respect to the roll of adhesive tape. Basically there are also bearings that are not in the center of the roll of adhesive tape. Nevertheless, central warehouses have particularly proven themselves.

The application device comprises an application roller. With the application roller, the adhesive tape section can be pressed against the substrate to which the adhesive tape is to be stuck in order to achieve adhesion. It is preferably an application roller with a roller surface made of or comprising plastic. The plastic is preferably more elastic and / or softer than the material, in particular the plastic, the friction bridge, particularly preferably the deflecting bead and / or the bridge sliding surface. Although the application roller and the friction bridge are optimized for contact with the adhesive tape section, a more elastic and / or softer roller surface has proven to be advantageous. The rolling surface can compensate for unevenness in the substrate to which the adhesive tape is to be applied by means of a certain softness and / or elasticity, so that a more even pressing is facilitated. The frictional resistance of the application roller, when it is not rotating, is preferably higher than the frictional resistance of the deflection bead and / or the bridge sliding surface. It has thus proven useful to select a softer material for the roller surface and / or application roller than for the friction bridge.

In a particularly preferred embodiment, the roller surface and / or application roller is provided with a powder, in particular coated. In one embodiment, the powder is talc or powdered talc. The powder adheres to the roller surface and / or application roller and improves the unwinding of the adhesive tape. This works particularly well when the rolling surface is more elastic and / or softer than the material, in particular the plastic, the friction bridge, in particular the deflection bead and / or the bridge sliding surface.

In one embodiment, the friction bridge is arranged between the application roller and the bearing, in particular when the bearing is in the second storage position.

In an expedient embodiment, the friction bridge and / or deflection bead and / or bridge sliding surface is installed in the adhesive tape dispenser in such a way that it does not come into contact, in particular does not come into contact, with the generic use for applying adhesive tape on a flat surface can. This makes it easier to unroll.

The friction bridge is preferably designed and set up to come into contact with the non-adhesive side of an adhesive tape when used in accordance with the generic type.

It is also preferred if the bridge sliding surface has a bridge sliding surface length which is greater than or essentially the same as the length of the application roller. Two lengths are essentially the same size, at least when the longer of the lengths is not more than 20%, in particular not more than 10%, longer. It has been shown that the adhesion of the adhesive tape section to the bridge sliding surface is better, the larger the bridge sliding surface. The friction bridge and / or the deflection bead and / or the bridge sliding surface preferably has a sliding surface width which is at least 10% of the sliding surface length of the deflecting bead and / or the bridge sliding surface, in particular at least 25%. The width of the sliding surface should, however, preferably not be more than 200%, in particular not more than 100%, particularly preferably not more than 70%, of the sliding surface length of the bridge sliding surface. A comparatively large sliding surface width of the deflection bead and / or the bridge sliding surface ensures better adhesion of the adhesive tape section. However, if the sliding surface width of the bridge sliding surface becomes too large, it is more difficult to accommodate it within the adhesive tape dispenser in a space-saving manner. Said sliding surface width is preferably determined in the direction in which the adhesive tape section slides over the bridge sliding surface. Said sliding surface length is preferably determined orthogonally to this direction.

The friction bridge and / or the deflecting bead and / or the bridge sliding surface preferably has a bridge width which is at least 10% of the bridge length of the friction bridge, in particular at least 25%. The bridge width should, however, preferably not be more than 200%, in particular not more than 100%, particularly preferably not more than 70%, of the bridge length of the friction bridge. Said bridge width is preferably determined in the direction in which the adhesive tape section slides over the bridge sliding surface. Said bridge length is preferably determined orthogonally to this direction.

The bridge sliding surface preferably has a size of at least 1 cm ² , in particular at least 2 cm ² , particularly preferably at least 5 cm ² .

The friction bridge preferably comprises a plastic, in particular consists predominantly, i. at least 50% of this, preferably at least 80% or completely. In principle, a metal friction bridge is also conceivable, but plastics have proven particularly useful. Said plastic is preferably selected from a group consisting of polyamide, polycarbonate, acrylonitrile-butadiene-styrene, styrene-acrylonitrile copolymer, polyacetals, in particular polyoxymethylene (POM), polyurethane, polyketone, polyester-urethane rubber, polyether ketone, in particular PEK, PEKK , PEEEL, polymethacrylate. Hard plastics have proven to be particularly suitable, in particular with regard to adhesive properties and friction. The friction bridge preferably comprises the plastic polyamide, in particular polyamide 6.6 or polyamide 6. Polyamide 6.6 has proven to be particularly suitable. Polyoxymethylene (POM) has also proven to be particularly suitable. With POM it was found that the friction is reduced and the electrostatic charge is improved. It was found that polyamide and / or polyoxymethylene, in particular polyoxymethylene, is associated with improved, in particular electrostatic, adhesion of adhesive tape sections to the deflecting bead and / or, in particular and, the bridge sliding surface. The transverse elevation and / or deflection contact surface of the deflection bead or the deflection bead or the bridge sliding surface, in particular the friction bridge, or the transverse elevation and / or deflection contact surface of the deflection bead and the bridge sliding surface or the deflection bead and the bridge sliding surface preferably contain polyamide, in particular polyamide 6.6 and / or polyamide 6, and / or a polyacetal, in particular polyoxymethylene, or, which is preferred, consist of it, with polyoxymethylene being preferred.

The aforementioned plastic of the friction bridge preferably forms the surface of the bridge sliding surface and / or, preferably and, deflection bead, in particular the surface of the entire friction bridge. The bridge sliding surface and / or the deflecting bead preferably consists of one of the plastics mentioned, in particular polyamide and / or polyoxymethylene. The core of the friction bridge can also be formed from a different plastic, for example that of the other components of the adhesive tape dispenser, or else consist of a different material, for example a metal.

In a further embodiment, the friction bridge is made in one piece, in particular from one of the plastics mentioned.

The friction bridge is preferably fastened in a rotationally fixed manner via at least one, in particular mechanical, fixing element. Alternatively or additionally, the friction bridge can be glued to the rest of the adhesive tape dispenser or can be made in one piece with it. Screws, nails, bolts, etc. have proven to be suitable as fixing elements, and these can be made of metal or plastic, for example. The friction bridge is preferably fastened in a rotationally fixed manner via a first and a second fixing element. Two to four fixing elements are particularly suitable for preventing any rotation.

The friction bridge can comprise at least one stiffening leg. The stiffening leg gives additional stability. A first stiffening leg can be provided for the first fixing means and a second stiffening leg for the second fixing means.

The friction bridge is preferably connected to the rest of the adhesive tape dispenser in a rotationally fixed manner at at least four points.

The friction bridge includes a deflection bead. It is preferred here if, in the generic use of the adhesive tape dispenser, the adhesive tape section is deflected at the deflection bead, preferably a deflection by at least 45 °, in particular by at least 90 °, particularly preferably by more than 90 °.

The deflection bead can be connected in one piece to the bridge sliding surface. It can also be designed as a deflection pin. The deflecting pin is designed to be rotatable or non-rotatable, preferably non-rotatable. The deflecting bead can also be designed to be spaced apart from the bridge sliding surface, in particular spaced apart by a bridge recess.

The deflecting bead is preferably rounded off with a central osculating circle. Preferably, the rounding or a cross section of the rounding has at least one rounded area with a point, in particular a second point, whose osculating circle, also called the circle of curvature, has an average inverting circle radius, in particular a second average inverting radius, of 0.1 mm to 50 mm, preferably 0 , 2 mm to 20 mm, particularly preferably 0.7 to 10 mm. The deflecting bead can also be formed by a deflecting pin with said mean osculating circle radius.

The friction bridge preferably includes an, in particular concave, receiving arch. It is particularly preferred if the receiving arch ensures that the friction bridge does not collide with the application roller, thus preventing friction between the application roller and the friction bridge by stepping back in this area. The application roller preferably adjoins the receiving arch.

In an expedient embodiment, the friction bridge comprises a deflection section, in particular a, preferably rounded, deflection edge. The deflection section is preferably designed to detach the adhesive tape section from the friction bridge, if it is in contact with it. In numerous configurations, the deflection section, in particular the deflection edge, marks one end of the bridge sliding surface. A surface inclined with respect to the bridge sliding surface can adjoin the deflecting section, in particular the deflecting edge or bridge sliding surface. In some embodiments, the friction bridge comprises said deflecting section, in particular said deflecting edge, the deflecting section being closer to the application roller than the deflecting bead, in particular wherein the adhesive tape dispenser is designed and set up so that an adhesive tape section of an adhesive tape roll on the bearing slides over the deflecting section when it is unrolled and is deflected there and / or is separated from the friction bridge. It can be provided that the adhesive tape does not, or only partially, contacts the inclined surface in the case of the generic use.

In some configurations, the friction bridge comprises a rounded contact bead in addition to the deflection bead. The rounded contact bead should preferably receive the adhesive tape, in particular remove it. The deflecting bead can also be rounded and receive the adhesive tape. A contact bead is therefore not absolutely necessary. If a contact bead is provided, it has proven to be useful if the deflecting bead is rounded less than the contact bead, in particular the rounding of the contact bead describes a larger mean osculating circle radius. The contact bead is preferably provided closer to the deflecting bead than to the deflecting section, in particular the deflecting edge. It is also particularly preferred if the bridge sliding surface extends up to the deflection bead and the rounded contact bead is beyond the deflection bead. In some embodiments, the adhesive tape first contacts the rounded contact bead of the friction bridge when it is unrolled.

In some preferred embodiments, a contact bead is not provided and the, in particular rounded, deflection bead accepts the adhesive tape when used in accordance with the generic type.

The deflecting bead preferably merges continuously into the bridge sliding surface, in particular continuously in the mathematical sense and / or without the formation of a sharp edge.

Said contact bead preferably has a rounded area in cross section with a first point, the osculation circle of which has a first mean osculation circle radius. The deflecting bead preferably has a rounded area in cross section with a second point, the osculating circle of which has a second mean osculating circle radius. In one embodiment, the second mean osculating circle radius is many times smaller than the first mean osculating circle radius, in particular at least three times smaller. The second mean osculating circle radius is preferably 0.1 mm to 10 mm, in particular 0.2 mm to 3 mm, particularly preferably 0.7 to 2 mm. It is assumed that a second mean osculating circle radius is associated with greater friction and thus with greater electrostatic charge.

The bearing for a roll of adhesive tape, which can in particular be rotated about its own axis, can be pivoted between a first and a second storage position, in particular from the first to the second storage position and not further and vice versa, the bearing being attached to a pivot arm which is connected to a preloaded swing arm spring, the swing arm spring urging the swing arm and the bearing in the direction of the second bearing position, the bearing in the second bearing position being closer to the deflection bead of the friction bridge than in that of the first bearing position. The transverse rod for the activation plate is preferably oriented orthogonally to a pivot rod, the pivot arm pivoting about the pivot rod.

At least one fixation projection, in particular a first and, preferably opposite, second fixation projection is preferably provided opposite the bridge sliding surface, in particular with a passage between the first and second fixation projection. The at least one fixing projection preferably does not contact the adhesive tape section when used in accordance with the generic type and is spaced apart from the bridge sliding surface and the friction bridge. Preferably, the at least one fixing projection is permanently installed, i.e. neither rotatable nor pivotable. The fixing protrusion additionally secures the adhesive tape section and shields the bridge sliding surface.

The handle preferably has a longitudinal axis, in particular the longitudinal axis already described, the longitudinal axis and the application roller being located on opposite sides of an intermediate plane, the intermediate plane being parallel to the longitudinal axis is arranged and the bearing axis of the bearing is in the first bearing position in the intermediate plane. In one embodiment, this longitudinal axis is less than 5 cm, preferably less than 3 cm, away from the bearing in the first storage position. This enables a particularly efficient and compact design.

In an expedient embodiment, the bearing for a roll of adhesive tape can be pivoted into such a position that a line and / or plane connecting the application roller axis of the application roller and the bearing axis of the bearing can be defined, which line runs essentially parallel to at least one section of the bridge sliding surface. “Essentially parallel” means that the deviation from an exactly parallel orientation is less than 20 °, in particular less than 10 °, preferably less than 5 °. This can be the case, for example, in the first storage position or in a third storage position, the third storage position being between the first and second storage positions. As an alternative or in addition, it is preferably provided that the bridge sliding surface runs essentially parallel to the application roller axis and / or bearing axis. In one embodiment, a line connecting the application roller axis and bearing axis can be defined, the bridge sliding surface being oriented essentially parallel to this line and essentially parallel to the application roller axis and / or bearing axis.

In some configurations, the bridge sliding surface is curved. Preferably, however, the bridge sliding surface is planar and flat, i.e. without curvature.

In a further useful embodiment, the adhesive tape dispenser comprises a, in particular removable, cutting knife, in particular with a toothing, which can be transferred from a shielded first knife position into a second knife position in which the cutting knife protrudes freely. It has been shown that the cutting knife makes it easier to cut off the adhesive tape strip after application. The two knife positions reduce the risk of injury and prevent accidental disconnection. For example, a button or slide control can be provided with which the knife is manually extended. However, it has proven useful if the adhesive tape dispenser comprises a pretensioned activation plate, the pretensioned activation plate, when it is loaded and moved with pressure, transfers the cutting knife counter to the direction of movement of the activation plate into the second knife position in which the cutting knife protrudes freely. This automatism makes it easier to separate the adhesive tape.

The cutting knife is preferably connected to a receiving block or comprises one, wherein the receiving block can facilitate fixing the cutting knife and replacing the cutting knife. The cutting knife can preferably be detached from the receiving block, in particular detached without tools.

In some embodiments, the tape dispenser comprises an activation plate spring with a first wire wound in helical form around a crossbar and a second wire wound in helical shape around said crossbar, the first and second wires being connected in one piece by a bracket, the activation plate having a recess and / or Has projection for fixing the bracket. It has surprisingly been found that the separation of an applied adhesive tape section now takes place better. This is by no means a given. As far as activation plates are described in the prior art, the cross bar is considered to be sufficient to fix the activation plate spring in a rotatable manner. However, an additional fixation is achieved by means of the recess and / or projection. In principle, adhesive bonding is also possible, but mechanical fixing has proven itself, in particular in that the bracket is clamped or held by the recess and / or projection. It is assumed that the activation plate now hits harder, which makes it easier to separate an applied section of adhesive tape.

The activation plate can additionally have reinforcing elements, in particular a first and second reinforcing element.

The adhesive tape dispenser preferably comprises an end sliding surface, in particular adjacent to a gap through which the cutting device, in particular the cutting knife, emerges. In one embodiment, the end sliding surface comprises metal, in particular aluminum. It is therefore provided shortly before the end at which the section of adhesive tape is severed. The end sliding surface can therefore also be referred to as the end contact surface for a section of adhesive tape. The end sliding surface or the end contact surface helps guide the adhesive tape, with electrostatic interactions being assumed to play a decisive role, without being bound by theory.

In an expedient embodiment, the adhesive tape dispenser comprises a roll of adhesive tape and an adhesive tape section unwound from the adhesive tape roll, which is connected to the adhesive tape roll, the adhesive tape section having an adhesive tape side and an opposite non-adhesive tape side, the opposite non-adhesive tape side with a section on the deflection bead and the Application roller or rests on the deflection bead and the bridge sliding surface and the application roller.

In a further expedient embodiment, the adhesive tape dispenser does not include a roll of adhesive tape and any section of adhesive tape unrolled from the roll of adhesive tape, but is suitable for these.

The adhesive tape dispenser is preferably designed and set up to guide the adhesive tape section around the deflection bead during application, the adhesive tape edges being at least partially spaced from said deflection bead, while the adhesive tape section rests centrally on the deflection bead. The invention also relates to an adhesive tape dispenser for the noise-reduced application of adhesive tape with an adhesive tape dispenser as described above, with an adhesive tape section being guided around a deflection bead during application and the edges of the adhesive tape being at least partially spaced from said deflection bead, while the adhesive tape section rests centrally on the deflection bead .

The invention also relates to a method for the noise-reduced application of adhesive tape with an adhesive tape dispenser as described above, the adhesive tape section being guided around a deflecting bead during application and the edges of the adhesive tape being at least partially spaced from said deflecting bead, while the adhesive tape section rests centrally on the deflecting bead .

The invention is based on the surprising finding that a deflecting bead combined with a rotationally fixed bridge sliding surface results in considerable improvements in the application of adhesive tape sections. The adhesive tape section adheres by means of the friction bridge. Surprisingly, a metal bracket which presses the section of adhesive tape against the application roller is no longer required. Rather, it has been shown that adhesion in the direction of or on the application roller can be brought about by the friction bridge, in particular without an element resting on the adhesive side of the adhesive tape section. Knotting or accidental detachment is prevented. In this case, the specific shape and, in particular, the orientation and positioning of the deflecting bead and, in particular, the bridge sliding surface and, above all, a suitable choice of material, can further improve said adhesion. While there are certainly solutions in the prior art to ensure the transfer of the adhesive tape to the cutting knife, the present invention shows that a considerable improvement is nevertheless possible here by the way the tape is carefully checked without altering the tape itself. It was also possible to reduce the development of noise with numerous of the configurations described, in particular with a transverse elevation. In particular, it has proven to be very advantageous that after a section of adhesive tape has been severed with the cutter of the adhesive tape dispenser according to the invention, the adhesive tape remains in contact with the end sliding surface or end contact surface. In this way, the adhesive tape is immediately available for the subsequent gluing process. Another advantage here is that the adhesive tape, after leaving the rotationally fixed friction bridge containing the deflecting bead and the bridge sliding surface, reaches the end sliding surface / end contact surface reliably and reproducibly via the application roller without turning over on itself under adhesion. This also ensures safe work, in which, moreover, there are no rejects in the form of adhesive tape to be discarded.

Further features and advantages of the invention emerge from the following description, in which exemplary embodiments of the invention are explained by way of example with reference to schematic drawings, without thereby limiting the invention.

The adhesive tape section 103 comprises an adhesive adhesive tape side 102 and a non-adhesive adhesive tape side 104. The adhesive tape dispenser 1 comprises a cutting knife 23 with a toothing, which can be transferred from a shielded first knife position into a second knife position in which the cutting knife 23 protrudes freely. The first knife position is shown here. The adhesive tape dispenser 1 further comprises a pretensioned activation plate 7, the pretensioned activation plate 7, when loaded and moved with pressure, transfers a cutting knife 23 counter to the direction of movement of the activation plate 7 into a second knife position in which the cutting knife 23 protrudes freely. The activation plate is rotatably mounted around a cross bar 8. A pivot rod 9 allows the bearing 3 to pivot by means of the pivot arm spring 10. This pivoting mechanism is described in more detail in connection with FIG Figure 7 explained. The handle 2 comprises handle holes 13 and is connected to the rest of the adhesive tape dispenser via a connecting piece 11. The roll of adhesive tape 100 is in a semi-open cylindrical housing 12. The bearing 3 is rotatable about a bearing axis A1, a swivel arm (cf. Figure 7 ) pivotable about a pivot arm axis A2 and the application roller 4 rotatable about an application roller axis A3. The bearing 3 in the form of a central bearing for a roll of adhesive tape 100 can be pivoted into such a position that a line X is defined between an application roller axis A3 of the application roller 4 and a bearing axis A1 of the bearing 3, which runs parallel to the central orientation of the bridge sliding surface 6 (in the present case not quite parallel yet).

Figure 2 shows a section of the adhesive tape dispenser 1 from the direction of the friction bridge 5 with the bridge sliding surface 6. The friction bridge 5 comprises a deflection section 28 in the form of a deflection edge, the deflection section 28 being closer to the application roller 4 than the deflection bead 26. The receiving device 33 comprises the half-open cylindrical housing 12, in which the roll of adhesive tape 100 is accommodated and is rotatably fixed on the bearing 3 in the form of a central bearing. The application device 38 comprises a rotatable application roller 4. A surface 16 which is inclined with respect to the bridge sliding surface 6 can also be seen, these being separated from one another by the deflection section 28. A first fixing projection 14 and a second fixing projection 15 are located at a distance from and opposite from the bridge sliding surface 6. The application roller 4 is rotatably fixed on a leg 17 of the semi-open cylindrical housing 12. Of the For the sake of clarity, the handle has been included in Figure 2 not reproduced. The bridge sliding surface has a sliding surface length L2 which is greater than or essentially the same as the application roller length L1 of the application roller. The application roller length L1 is usually selected to match the width of the adhesive tape. The bridge sliding surface also has a sliding surface width B1 and the friction bridge has a bridge width B2, which is at least 25% of the sliding surface length of the bridge sliding surface L2.

Figure 3 shows a section of the adhesive tape dispenser 1 from the direction of the cutting knife 23 and the pretensioned activation plate 7. Said cutting knife 23 can be seen with a toothing, which can be transferred from a shielded first knife position into a second knife position in which the cutting knife 23 protrudes freely. For this purpose, the adhesive tape dispenser 1 comprises said pretensioned activation plate 7, the pretensioned activation plate 7, when it is loaded and moved with pressure, transfers the cutting knife 23 counter to the direction of movement of the activation plate 7 into a second knife position in which the cutting knife 23 protrudes freely. The activation plate 7 comprises an activation plate spring 40 with a first wire 21 wound in helical form around a transverse rod and a second wire 22 wound in helical form around a transverse rod, the first and second wires 21, 22 being connected in one piece by a bracket 18, the activation plate 7 has a recess and / or projection for fixing the bracket 18. The bracket is shown in broken lines because it is actually covered by the activation plate 7. The activation plate 7 comprises a first and second reinforcing element 19, 20 and a recess 36 for the bracket 18. Between the cutting knife 23 and the application roller 4 there is an end sliding surface / end contact surface 24, which are held by legs 17 of the semi-open cylindrical housing.

Figure 4 shows the friction bridge 5 with the bridge sliding surface 6 and a deflection bead 26 and a deflection section 28 in the form of a deflection edge. The bridge sliding surface 6 extends in this embodiment from the deflecting bead 26 to the deflecting section 28. A first stiffening leg 30 comprises a first mechanical fixing element 29 and a second stiffening leg 32 a second mechanical fixing element 31. A surface 16 inclined with respect to the bridge sliding surface 6 is formed by the deflecting section 28 delimited. The friction bridge 5 comprises a rounded contact bead 41 for receiving the adhesive tape section and a concave receiving arch 27 in order to prevent frictional contact with the application roller 4. The roll of duct tape preferably presses on the contact bead 41. The deflection bead 26 and in a preferred embodiment also the bridge sliding surface 6 contact the adhesive tape, which brings about improved adhesion of the adhesive tape to the non-adhesive side.

Figure 5 shows a schematic view of an alternative embodiment of the adhesive tape dispenser 1. Here, the handle 2 in the form of a radial handle has a longitudinal axis 34, the longitudinal axis 34 and the application roller 4 being on opposite sides of an intermediate plane 35, the intermediate plane 35 being parallel to the longitudinal axis 34 is arranged and the bearing axis R of the bearing 3 is in the form of a central bearing in the first storage position in the intermediate plane 35. The position of the bridge sliding surface 6, the activation plate 7 and the bracket 18 can also be seen. Here, the application roller (4) and the bearing (3) are on the same side with respect to the longitudinal axis (34) if a cross-section is orthogonal to the bearing axis becomes.

Figure 6 shows a perspective view behind the activation plate 7. The activation plate 7 comprises an activation plate spring 40 with a first wire 21 wound in helical form around a transverse rod and a second wire 22 wound in helical form around a transverse rod, the first and second wire 21, 22 through a Brackets 18 are connected in one piece, the activation plate 7 having a recess and / or projection for fixing the bracket 18. The activation plate 7 comprises a first and second reinforcing element 19, 20 and a projection 37 for the bracket 18.

Figure 7 shows a section of the receiving device 33 with a pivotable and rotatable bearing 3 in the first bearing position. The bearing 3 in the form of a central warehouse is designed here as a square and can rotate around its own axis. It is fixed on a pivot arm 39, the pivot arm 39 being pivotable about the pivot rod 9. The swivel arm 39 is pretensioned by the swivel arm spring 10, so that it moves automatically in the direction of the bridge sliding surface 6. The handle 2 can also be seen. The swivel arm 39 is pretensioned in such a way that it or the bearing 3 automatically swivels in the direction R of the bridge sliding surface when released, ie to the second bearing position.

Figure 8 shows one to Figure 4 similar friction bridge 5, the deflecting bead 26 being formed here by a deflecting pin. Incidentally, the design of the Figure 8 identical to the Figure 4 .

Figure 9 shows part of the Figure 4 namely the end of the friction bridge with the deflecting bead 26 and the rounded contact bead 41. The rounded contact bead 41 has a rounded area in cross section with a first point P1, the osculation circle of which has a first mean osculation circle radius R1. The deflecting bead 26 has, in cross section, a rounded area with a second point P2, the osculating circle of which has a second mean osculating circle radius R2. The second mean osculating circle radius R1 is many times smaller than the first mean osculating circle radius R2.

Figure 10 shows one to Figure 4 Similar friction bridge 5, the deflection bead 26 being spaced apart from the bridge sliding surface 6 by a bridge recess 42. In principle, the deflecting bead 26 can also be designed as a deflecting pin spaced apart by the bridge recess 42 (not shown here). Incidentally, the design of the Figure 8 identical to the Figure 4 .

Figure 11 shows an embodiment of the friction bridge 5 with the bridge sliding surface 6 and a deflecting bead 26 and a deflecting section 28. The bridge sliding surface 6 extends in this embodiment from the deflecting bead 26 to the deflecting section 28. A surface 16 inclined with respect to the bridge sliding surface 6 can also be seen, whereby these are separated from one another by the deflection section 28. A first and a second fixing element 29, 31 are provided. The deflecting bead 26 comprises a transverse elevation 43 in the form of a transverse arch with a transverse elevation maximum 45 and two transverse elevation minima 44. Said transverse elevation 43 extends between a first friction bridge side 46 and an opposite, second friction bridge side 47. The transverse elevation maximum 45 is spaced from the friction bridge sides 46, 47 in front of and in the middle between said friction bridge sides.

Figure 12 shows again the design of the friction bridge 5 from a different perspective. Regarding the reference numbers, refer to Figure 11 referenced. A concave receiving arch 27 of the friction bridge 5 can also be clearly seen here, in order to prevent friction on the application roller (cf. Figure 1 ) to prevent.

Figure 13 shows a to Figure 12 analogous design of the friction bridge with a rounded contact bead 26, but without a transverse elevation. When a section of adhesive tape slides over this contact bead 26, all areas of the adhesive tape rest. It has been shown that such designs are somewhat louder than the designs in which the edge of the adhesive tape is exposed.

Figure 14 shows a further embodiment of the friction bridge 5 with the bridge sliding surface 6 and a deflection bead 26 and a deflection section 28. Apart from the fact that this embodiment of the friction bridge 5 is somewhat more elongated than the embodiment of FIG Figures 11 and 12 the structure is identical and only the perspective is different. The bridge sliding surface 6 extends in this embodiment from the deflecting bead 26 to the deflecting section 28. A surface 16 inclined with respect to the bridge sliding surface 6 can also be seen, these being separated from one another by the deflecting section 28. The deflecting bead 26 comprises a transverse elevation 43 with a transverse elevation maximum 45 and two transverse elevation minima 44. Said transverse elevation 43 extends between a first friction bridge side 46 and an opposite, second friction bridge side 47. The transverse elevation maximum 45 is spaced from the friction bridge sides 46, 47 and is in the middle between said ones Friction bridging sides. It is also shown how the adhesive tape section 103 rests against the deflection bead 26, the adhesive tape edges 105 being spaced apart from the deflection bead 26. The contact surface length L3 of the deflecting contact surface 48 of the deflecting bead 26 is less than the adhesive tape width B3 of the adhesive tape section. The adhesive tape width B3 corresponds to the length of the dashed line of the adhesive tape section 103 in FIG Figure 14 .

Figure 15 shows a to Figure 14 Analogous view, the transverse elevation 43 being designed as a polygonal transverse elevation. But here, too, the deflecting bead 26 comprises a transverse elevation maximum 45 and two transverse elevation minima 44, said transverse elevation 43 extending between a first friction bridge side 46 and an opposite second friction bridge side 47. The transverse elevation maximum 45 is at a distance from the friction bridge sides 46, 47, namely in the middle between said friction bridge sides. In this embodiment, the transverse elevation has a cross section in which it has two legs which comprise transverse elevation minima and a linear connecting line between the legs which comprises the transverse elevation maximum. It is also shown how the adhesive tape section 103 rests against the deflection bead 26, the adhesive tape edges 105 being spaced apart from the deflection bead 26.

Figure 16 shows a further embodiment of the friction bridge 5 with the bridge sliding surface 6 and a deflection bead 26 and a deflection section 28. The deflection bead 26 extends between the friction bridge sides 46, 47. The bridge sliding surface 6 extends from the deflection bead 26 to the deflection section 28. It can also be seen a surface 16 inclined with respect to the bridge sliding surface 6, these being separated from one another by the deflecting section 28. The deflecting bead 26 has no transverse elevation 43, has however, a deflecting contact surface 48 with a contact surface length L3 less than the adhesive tape width B3 of the adhesive tape section 103, the adhesive tape edges 105 being at a distance from the friction bridge 5.

Figure 17 shows a schematic view of some configurations of the friction bridge 5. The transverse elevation has at least one cross section Q which extends orthogonally to the deflection sliding surface and which at the same time extends parallel to the bridge sliding surface. It can also be seen how the adhesive tape section 103 is guided around the friction bridge 5 and is deflected at the deflection bead 26 with transverse elevation 43.

Figure 18 shows some configurations of the cross-sections Q of the transverse elevation 43. The cross-sections through the remaining friction bridge 5 and 5 only concern the contour of the transverse elevation 43 with a cross-section as in FIG Figure 17 shown. Figure 18 a) relates to the cross section Q of a transverse arch with a transverse elevation maximum 45 and two transverse elevation minima 44. Figure 18 b) relates to the cross section Q of a polygonal transverse elevation with a transverse elevation maximum 45 and two transverse elevation minima 44. Figure 18 c) relates to the cross section Q of a further embodiment of a transverse arch with a transverse elevation maximum 45 and two transverse elevation minima 44. In each of the cross sections Q, the transverse elevation is visible as a raised and / or curved contour.

Figure 19 shows a further embodiment of the friction bridge with a rounded contact bead 26 and a transverse elevation. The inclined surface 16 adjoins the bridge sliding surface 6. A receiving arch 27 is encompassed by the friction bridge. A first and a second mechanical fixing element 29, 31 can also be seen as optional components.
