Description

[0001]Profile Cover Mounting The invention relates to a mounting device for attaching a cover to a profile rail according to the preamble of claim 1, as well as a corresponding method for attaching such a cover with a deformation aid. Specifically, the invention relates to a roller specifically designed for mounting a translucent plastic cover to a U-shaped lighting profile rail, in which rail illuminants such as LED strips or the like are housed or mounted. Generic lighting profiles or light rails within the meaning of the present invention are shown, for example, in WO2023 / 012507 or WO2023 / 012744. In these, a rigid profile rail, e.g. made of metal or plastic, with a cross-section that is essentially approximately U-shaped or H-shaped, is fitted with illuminants inside. For aesthetic reasons, to protect against dirt or contact, and / or for lighting-related reasons,Such lighting profiles are often provided with a cover. This cover is typically supplied as a long, straight plastic rod with the profile rail and is attached to the profile by hand after the lighting has been installed. Handling and installing the cover is often challenging, as the cover consists of long, thin strips that are difficult to handle. Due to their geometry alone, the covers are often so flexible that they bend or sag during carrying, transport, and installation, or can even break. Attaching the cover to such lighting can be even more difficult, as such lighting profiles are often mounted on ceilings or suspended freely, e.g., on cables. A further difficulty is the transport-related maximum length of the cover strips of 2 m.4 m or 5 m – depending on the manufacturer and method of transport. This often results in joints in the cover, which are not only unsightly, but also difficult to install with a clean, seamless connection. The translucent covers must also be kept clean to ensure a visually appealing appearance. Therefore, no dirt, dust, or fingerprints should remain, which is why installation should preferably be carried out with clean gloves, which increases the installation effort. The known solutions have disadvantages in one way or another, particularly with regard to handling of the consumables, their transport, ease of use, significant waste, difficulties during the installation process, numerous joints, etc., which increases the material expenditure and the amount of waste. The object of the present invention is therefore to create a device or provide a methodwhich does not have or minimizes the aforementioned disadvantages. In particular, an improved assembly for a profile rail cover is to be provided, which leads to less waste and consistently allows for high processing quality. Specifically, an assembly method is to be developed that is simple and reliable to use. For this purpose, a corresponding assembly device can be provided that implements this method or facilitates its implementation. In addition to simplifying assembly, special tasks include, for example, avoiding / reducing joints, avoiding / reducing finger contact with the cover, avoiding / reducing offcuts and waste, reusability of leftovers, reliable installation even in difficult, confined installation locations,etc. The objects are achieved by the features of the independent claims. Advantageous developments and embodiments are set forth in the figures and in the dependent claims as well as in the following description. According to the invention, a profile cover mounting device is provided which is designed for attaching a cover to a profile rail. This profile cover mounting device is also referred to below as a mounting device or roller. In completely different technological contexts, the term "roller" is typically used, for example, for window seals that are pressed into grooves on the windows. This is obviously not what is meant in this document. Also clearly not meant is a device for inserting LED strips,Such as the "Roller for LED Strips / 8mm" from kmd Industrievertretungen (www.km-decor.ch / de / produkt / einroller-fuer-led-stripes-8mm / - accessed on February 27, 2024). In this respect, the term is now being used in a new way for a new use and a new device. A preferred embodiment of the invention or of the roller is designed, for example, for mounting a translucent plastic cover on a U-shaped lighting profile rail, for example, an aluminum or plastic profile, which has an initially continuous open area along its length for the light exit, which is to be closed with a cover in the form of a translucent, specifically transparent, translucent, frosted-glass-like plastic cover.In addition to physically sealing the profile against dust or contact, the plastic also acts as an optical diffuser for the light emission. Such profile rails can have special dimensions of, for example, approximately 1 to 12 cm in cross-section and can be as long as the lighting is required – usually in areas of more than one meter up to several tens of meters. The profile rail can also be cut to length to facilitate / enable its transport. For example, typical profile rails for such applications are roughly U-shaped in cross-section, or they circumscribe a rectangle or square with one (at least partially) open side, with dimensions of, for example, 20 mm by 20 mm or 50 mm by 40 mm. In other embodiments, the profile rails can also be roughly H-shaped in cross-section, with two side walls and a central web, as well as two (at least partially) open surfaces.e.g., an open front side (to be covered) for the light exit and an open rear side for mounting and / or for the power supply connection. Specifically, these profile rails can also be designed with grooves and / or webs in cross-section. The term "longitudinal grooves" here encompasses not only an arbitrarily shaped, elongated recess, but also a channel formed between two raised longitudinal webs. For example, the profile rail can be designed with at least one lateral longitudinal groove in each of the raised longitudinal webs. In particular, the profile rail can be designed with longitudinal grooves or longitudinal webs in the area or at the light exit opening of the lighting profile, which are specifically designed to positively accommodate the cover on both sides. Preferably,that the cover is almost or essentially flush with the opening in the profile rail. In other embodiments, the cover can also be attached to the profile rail with a force-fitting or frictional fit, in particular by elastically bracing the cover and / or the profile rail. The cover can be an elastically bendable, especially rollable, translucent plastic strip, for example with an approximately rectangular cross-section and a width designed such that the cover can be positively received in the profile rail, especially in a cover-holding formation such as longitudinal grooves or between longitudinal webs. The height of the cross-section does not necessarily have to be constant across the width and should be selected to achieve sufficient light transmission, diffusion, and / or a specific light emission effect, for example in the range of 0.1 mm to 0.8 mm.specifically, approximately 0.15 to 0.25 mm. The length of the cover or cover strip is many meters, for example, approximately 10 to 40 meters, specifically, 20 meters per roll. The cover according to the invention can also be provided on large rolls with far more than this length and from there rewound onto the rolls of the inventive roller. The profile cover mounting device according to the invention, or the new roller, comprises an outer housing. This is preferably made of plastic and / or metal and serves to hold and handle the mounting device, specifically for holding a roll or spool for a quasi-endless cover.can therefore have an approximately cylindrical recess for such a roller and preferably a fastening option for the roller that can be rotated around its center. The roller diameter should be in the range of approximately 10 cm to 40 cm. The width of the roller or the profile cover mounting device is accordingly somewhat wider than the width of the cover. The cover to be mounted can be wound or wound onto such a roller, as an interchangeable part of the profile cover mounting device according to the invention, for preparation. The roller is inserted or inserted into the outer housing. To carry out the cover assembly, the roller must be inserted into the outer housing and the cover must be wound onto the roller. These elements can also be separate when delivered, during sale, storage, etc.to form a profile cover mounting device according to the invention. The outer housing forms at least one rail guide, with which the outer housing can be placed on the profile rail in a defined position and displaced along its longitudinal direction. The profile cover mounting device can thus be guided in or on the profile and displaced along the profile. For example, it can be moved glidingly on the open side of the profile rail, with the rail guide and profile rail providing lateral guidance in a defined position relative to each other. Preferably, the rail guide is also designed such that it can be clipped into the profile rail. For example, the rail guide can have recesses for this purpose that engage in the lateral grooves or guides into which the cover is then mounted. The roller can thus be designed such that it holds onto the profile rail when clipped in.specifically orthogonal to the plane of the cover. This can facilitate, for example, overhead work or similar, since the roller itself holds itself to the profile and cannot fall down, even if it is released. In other words, the outer housing, in a special embodiment, should also be designed so that it holds itself in the profile in an overhead application, while, for example, the assembly platform on which the fitter stands to work on the ceiling can be moved or relocated, which is often the case, especially with long lighting lengths. The outer housing further forms at least one insertion lug, which is shaped and arranged in such a way thatthat - during assembly of the cover by means of the assembly device according to the invention - this insertion lug effects such positioning and elastic deformation of the cover. As a result, the cover (40) can be inserted into the profile rail (50) in an area near the insertion lug (36). After the elastic deformation caused by the insertion lug has been reduced, the cover consequently remains in the profile rail. Preferably, the profile cover assembly device is designed such that, when it is pressed against the profile rail and moved along the profile rail, the deformed cover can be inserted into cover retaining recesses in the area of ​​the insertion lug - for example, in longitudinal grooves or between longitudinal webs on the profile rail - and, upon reduction of the elastic deformation, the cover can be moved outside a length range around the insertion lug which causes the deformation.is inserted in a form-fitting manner into these cover retaining recesses or engages and remains in this form-fitting manner. This allows for simple and securely positioned insertion of the cover into the cover retaining recesses of the profile rail by simply pulling the mounting device along the profile rail. Preferably, the insertion nose is shaped and arranged in such a way that it causes an elastic crowning or bending of a cross-sectional area of ​​the cover. In particular, the insertion nose can form a curve that protrudes downwards into the space in the direction of the profile rail, in particular a convex curve. This allows the cover to be deformed in a defined manner so that it can be inserted optimally. In another embodiment, an inwardly recessed curve can also be formed on the insertion nose.in particular, a concave curve. Advantageous geometric shapes of the insertion nose can be specifically tailored and optimized for the cover and profile rail used, for example, through calculations, simulations, and / or tests. Preferably, the lowest point of the insertion nose is lower than an upper support surface of the rail guide, which is designed to rest on an upper edge of the profile rail. Thus, when the assembly tool is applied to the profile rail, the insertion nose protrudes at least partially into the interior of the profile, which also elastically deforms the cover in this direction. This allows the cover to be inserted into the profile in a controlled and positioned manner by simply rolling it in using the roller. In another embodiment, the deformation could also occur in the other direction.which is possible in an analogous manner according to the invention. However, this is technically more complex in the design of the assembly tool, especially the design of the insertion nose, guides, holders, counterholders, etc. Preferably, the outer housing forms a handling formation, for example in the form of a finger rest, a push handle or the like. With this, the assembly device or the insertion nose can be pressed against the profile rail, making it easy to operate by hand. In particular, the handling formation is designed and arranged to apply a contact force with which the insertion nose and / or rail guide can be pressed against the profile rail - especially a contact force that is sufficiently large,to effect the elastic deformation of the cover. The profile cover mounting device should also fit comfortably in the hand. Versions for right- and left-handed users can be specially offered. In another embodiment, a roller according to the invention can also be mechanically applied to a profile and guided along it, with a machine applying the contact force and performing the guiding, thus essentially replacing the handling process with a machine assembly process. The profile cover mounting device is preferably shaped and configured such that the cover emerging from the profile cover mounting device at the insertion nose rests laterally on at least one, preferably two, edges of the profile rail or longitudinal webs during its assembly. Thus, a counterforce to the contact force exerted by the profile rail on the cover is exerted at this edge or these edges.which causes the elastic deformation of the cover. Specifically, the contact force acts via the insertion nose essentially centrally in the direction of the profile rail on the cover cross-section. Counterforces from the edges of the profile rail act laterally on the cover cross-section in the direction of the roller. This causes the cover cross-section to bend elastically in the center. The resulting bending radius reduces the overall width of the cover, which facilitates or enables insertion into the profile. In particular, according to the invention, the cover in its flat, stress-free state is as wide in cross-section as the inner width of the profile rail in its stress-free state. Specifically, it is approximately or exactly as wide as the interior of the cover retaining recesses into which the cover is inserted. Thus, with a width that corresponds approximately to the depth of the longitudinal grooves or the width between the longitudinal webs on the profile rail.into which the cover is to be inserted. This allows for a secure hold of the mounted cover in the profile rail. Preferably, the outer housing of the roller is provided with a counterholder in the area of ​​the insertion nose. This is designed and arranged such that an inserted cover can be guided between the insertion nose and the counterholder. This allows the cover to be additionally or more precisely defined in its position. Additionally or alternatively, the counterholder, in conjunction with the insertion nose, can also cause at least partial elastic deformation of the cover.so that their insertion is facilitated and / or the contact force can be reduced. Furthermore, the outer housing can additionally form at least one lateral guide element for the lateral positioning of the cover in the outer housing. This allows the lateral position of the cover relative to that of the profile rail or rail guide to be defined more precisely. For example, one side of the outer housing can be closed in the area between the unwinding of the cover from the roll and the insertion lug, and the opposite side can form a slot for inserting the cover, which slot is configured with the counterholder and / or at least one guide element. Preferably, the roll is provided with at least one range indicator. This can, in particular, be designed with a scale of values ​​​​of the cover length still present on the roll. This remaining length scale of the cover preferably does not increase linearly from the outside to the inside.whereby both the spiral shape and the tendency of the cover to unwind elastically on the roll are taken into account when forming the scale. This allows the installer to avoid fragmenting the cover, as it is always clear whether the cover on the roll is still sufficient for the current profile length. Otherwise, the roll can be replaced as a precaution, whereby the roll with the currently too short cover remainder can, if necessary, be reused later on a shorter profile rail. This avoids both waste and joints in the installed cover. The rail guide is preferably designed with at least two transverse webs spaced apart in the longitudinal direction of the profile in the direction of the profile width. These can, for example, be shaped such thatthat they can be placed laterally on an upper edge of the profile rail and partially protrude into the profile interior between them. Instead of or in addition to an inner lateral guide by protruding, the rail guide can also be located outside the profile width on a partial area of ​​the sides of the profile rail. This can ensure secure guidance or manual guidance of the roller, and in particular prevent jamming due to offset or slanting. In particular, the rail guide can have clip-in formations which are designed to clip into the cover retaining formations or lateral longitudinal grooves - especially those into which the cover is then inserted. This clipping is preferably carried out in such a way thatthat the mounting device automatically holds itself to the profile rail. Preferably, the roll is replaceably insertable or inserted into the outer housing. This makes the roller reusable. The rolls can also be optionally refilled or rewound from a large roll, which advantageously takes place when not in use. The roll can be specially designed to have an inner minimum radius, which is designed such that the cover used does not experience irreversible plastic deformation at this minimum radius. It is thus preferably only curved within the elastic range. Preferably, the cover is unwound from the roll in the profile cover mounting device in such a way that the cover is guided at least approximately parallel to the profile rail during unwinding. Specifically, the unwinding takes place in a rangein which the roll is closest to the profile rail and the cover is guided from there approximately parallel to the profile rail or slightly diagonally to it. This allows the cover to be fed advantageously to the profile rail and an initial relaxation of the roll winding takes place before the profile is inserted. In addition, such a flat guide in this area facilitates a defined positioning of the cover by means of guide elements, guide elements, and counterholders. Preferably, the roller is equipped in one embodiment with a separating or cutting device for the cover. This is preferably arranged in the area of ​​the insertion nose. With this, the cover can be cut, severed, scored, or marked. The roller with such an optional separating or cutting device can further simplify the cover assembly. This can avoidthat an additional tool is required. This separating or cutting device can preferably be formed in the area of ​​the insertion nose, so that separation can take place directly during rolling in and, in particular, the separation position can be easily adjusted to the profile length. Furthermore, a consistently clean – possibly angular – cut can be made, which can be difficult to achieve manually with scissors or the like. Alternatively or additionally, a marking aid can also be formed on the roller, with which a cutting mark for cutting to length can be created on the cover – for example, a line with a defined position and / or orientation, at which the cover can then be more easily separated – for example, also by hand with an external cutting tool. Analogously, the invention also relates to a method for mounting a cover on a profile rail, in particular a lighting cover on a lighting profile.with a deformation aid. The method is characterized by its process steps and activities and is not necessarily tied to specific hardware – however, it can be carried out, for example, with a profile cover mounting device or a roller, also described here in its design, and its structural details. The method comprises rolling the cover into lateral cover retaining recesses or longitudinal grooves of the profile rail and is carried out by pressing the cover against the profile rail using an insertion nose, which is designed and shaped in such a way that an elastic deformation and positioning of the cover by means of an insertion nose takes place in such a way that an outer width of a cross-sectional area of ​​the cover is reduced by the elastic deformation in such a way that it can be inserted between the cover retaining recesses and positioned between them.and with the pressed-on insertion lug sliding along the profile rail, during which the inserted cover rolls off a roller. Due to the elasticity of the cover, the elastic deformation of the cover is reversed in an area outside the insertion lug.so that the cover remains positively locked in the cover retaining recesses. Optionally, a movement opposite to the direction of the unwinding movement can also be used to remove the cover from the profile rail, in the form of an oppositely directed unwinding of the cover from the profile rail. The invention also relates to embodiments which not only comprise the profile cover mounting device or the roller itself – i.e., the outer housing and roller assembled or provided individually for this purpose – but also a cover mounting set consisting of at least one profile cover mounting device and at least one cover. In this set, the cover can preferably be wound on one or more rollers.However, it can also be provided for winding only. The invention also relates to a lighting rail set with at least one cover mounting set as described above and at least one profile rail. For example, a lighting profile rail with a light source that can be or has been inserted therein, in particular at least one LED strip, LED strips, or LED modules. Alternatively, a winding device according to the invention or the method can also be used analogously with non-transparent covers for electrical installations, for example, in cable ducts or the like. Further advantages, features, and details of the invention will become apparent from the following description.in which exemplary embodiments of the invention are described with reference to the drawings. The list of reference numerals, as well as the technical content of the patent claims and figures, is part of the disclosure. The figures are described coherently and comprehensively. Identical reference numerals denote identical components; reference numerals with different indices indicate functionally identical or similar components. They show: Fig. 1 shows an embodiment of a roller according to the invention as an assembly device in use during the assembly of a cover to a profile rail, in an overall view. Fig. 2a shows an embodiment of a roller according to the invention in an overview view with the position of the following partial sections marked. Fig. 2b shows a first partial view of the roller during assembly. Fig. 3 shows a second partial view of the roller during assembly.Fig. 4 shows a third partial view of the roller during cover assembly. Fig. 1 shows an example of an inventive assembly of a cover 40 of a profile rail 50 using a deformation aid. In the embodiment shown, the roller 30 designed according to the invention is used as the assembly device. This assembly device 30 is placed on the profile rail 50 and pressed against it. For example, the assembly device 30 can be designed with a finger rest 33 or a pressure handle or the like, which facilitates holding or pressing against the profile 50 without hindering rotation of the roll 31. The cover 40 is provided or dispensed from the roll 31 on which it has previously been wound. Advantageously, the roll 31 can be designed to be interchangeable, for example in order to accommodate different cover variants (e.g., with different optical properties,Colors, surfaces, shapes, etc.) and / or to be able to select a roll on which a sufficient length of cover is available, so that it preferably covers the entire profile length. For example, a previously partially used remaining roll 31 can be used, with a remaining cover length that is sufficient / suitable for the current profile. There may be designs in which the rolls 31 are provided / supplied with the cover 40 wound on them, or in which the rolls 31 can be refilled by the user, e.g., by transferring or rewinding the cover from a large roll onto the roll 31 of the roller 30. Alternatively, in another embodiment—e.g., for single-use applications—the rolls 31 with the cover can also be a non-replaceable part of the roller 30. In order to know or visualize the remaining length of the cover 40 on a roll 31,The roll 31 and / or the housing 32 of the roller 30 can be provided with a range indicator 38 or a fill level indicator, which is designed to make it detectable, estimable, or measurable how much length of cover 40 is currently on the roll 31. Preferably, the range indicator 38 is provided with a length scale, from which it is possible to read how many running meters of cover are still present on the roll 31. Preferably, the scale can assume higher values ​​from the outside to the inside of the roll diameter.so that the tensioned cover can develop from the roll center and conform to the outer roll radius, thus allowing a reliable remaining length reading. In particular, the scale is adapted non-linearly over the radius to take into account the spiral winding of the cover length. The cover 40 is unwound in the rolling device 30 from the roll 31 in the area of ​​its profile support in order to be mounted on the profile rail 50. According to the invention, an elastic shaping / deformation and positioning of the cover 40 - optionally additionally or alternatively also of the profile rail 50 - is carried out by the rolling device 30 in such a way thatthat the cover is attached / installed in the profile. Specifically, the cover is then held by positive and / or frictional engagement; for example, by inserting the cover 40 into designated retaining recesses such as longitudinal grooves 51 of the profile rail 50 or longitudinal webs. Examples and details of such deformation of the cover are further explained in the following detailed views. To install the cover, simply place the roller 30, with the cover 40 on its roller 31, onto the profile rail 50, or press or clip it in. Initially, the cover should protrude at least slightly from the roller 30. During the pressing process, the roller 30 is moved or pulled – e.g., slidingly – in the installation or movement direction 70, whereby the cover 40 is inserted into the profile 50. "Luxxit" is a trademark of the applicant; in the figures, this designation has no meaning.except that the devices shown are identified by this mark. Fig. 2a shows an overview of a roller 30 according to the invention during the attachment of the cover 40 to the profile rail 50. Specifically, a roll 31 with a cover 40 wound thereon (preferably with sufficient length for the entire profile length) is inserted into the roller 30, for example, clipped in a replaceable manner in the center of rotation of the roll, as shown. The cover 40 is mounted on the profile rail 50 in the area of ​​the marked circle 73 by means of the roller 30. To make this clearer, the profile rail 40 is shown in the illustration with a partial cutout 71 on the side in this area – which is possible in practice, e.g., for branches, feeds, special geometric boundary conditions, etc. – but as a rule, the profile rail 40 will be continuous on both sides.without such a physical recess 71. Fig. 2b shows the detailed view 73 marked with a circle in Fig. 2a, enlarged again. For easier recognition, the cover 40 is shown here with a pattern and - as mentioned - the profile 50 is shown graphically with a recess 71, so that the rolling-in process is more clearly visible. In the assembly device 30, the cover 40 is unwound from the roll 31 in the area of ​​the profile 50 and brought into the assembly position relative to the profile 50 with guide elements 34 and / or shaped elements 36 while the profile 50 is unrolled. Specifically, in the example shown, a cover 40 with a substantially rectangular cross-section is inserted into the profile 50. However, the invention is not necessarily limited to such a rectangular cross-sectional shape. For example, the cover 40 can also have longitudinal grooves or longitudinal webs and, for example, form a flat U-profile.whose side surfaces are designed to be held inside or outside on the profile side walls of the profile 50, for example, with appropriately designed shapes for a positive fit or under elastic tension of the material for frictional engagement. The cover is at least partially translucent for lighting, preferably transparent or translucent, for example acting as a diffuser. This allows light from a lighting element 52 (not shown here) mounted in the profile 50, for example via the lighting unit attachment 53, to be advantageously emitted, or the lighting unit 52 can also be physically and / or mechanically protected. In lighting applications, the profile rail 50 is usually an opaque lighting profile, usually made of metal or plastic, for example an extruded aluminum profile.which is essentially U-shaped. The profile width 54 and profile height 55 are usually in the range of approximately 8 mm to a few (e.g., up to 10) cm, especially in the range of 1 to 5 cm. These cross-sectional dimensions are usually considerably smaller than the profile length 56, which is usually significantly more than 10 cm, usually a few tens of centimeters to several meters. The profile rail 50 is usually designed with a cross-sectional shape that forms holding structures, in particular longitudinal grooves 51 or longitudinal webs 51 along the length 56, which are designed to accommodate lighting elements and / or the cover 40 and hold them in a form-fitting manner (or alternatively, a force-fitting manner, or both) in or on the profile 50. With the insertion lug 36 shown, the cover 40 is deformed in the elastic range of the material of the cover 40, for example, bent or cambered, and brought into the mounting position.in this example, below the upper edge of the profile 50. Furthermore, a guide element 34 can be formed below the cover 40 on the roller 30 in order to further define the position and / or shape of the cover 40. Fig. 3 again shows the pressing 72 of the roller 30 with a force and the movement 70 of the roller 30 along the profile 50. For this purpose, a rail guide 35 is advantageously formed on the roller 30, by means of which the roller 30 rests against the profile 50 and is guided relative to it. For example, the shape of the rail guide 35 can slide on the inside 57 or outside of the profile 50 and be supported in a defined position relative to the profile 50 and / or extend over a certain length in order to also define the angular orientation. The roller°30 can be designed in the area of ​​the profile rail°50, especially at the rail guide 35 and / or at the insertion nose 36 with a clip device or a locking formation,with which the roller 30 is held independently in the profile rail 50. This locking formation is particularly designed such that, when the roller 30 is pressed against the profile rail 50, it engages in the longitudinal grooves or cover retaining formations 51 (51a and 51b), thus preventing the roller 30 from being lifted off the profile rail 50, or only being able to do so with the application of external force in the opposite direction. In the figures, this is shown concealed by the profile rail. Due to the shape of the insertion lug 36 and the guide elements 34, 34b, and in particular under the action of the force 72, an elastic deformation 41 is caused in the cover 40 in the longitudinal region of the insertion - which is made visible here by the graphic recess 71.specifically, a crowning or bending of the cover. This reduces the width of the curved cover 40, allowing it to be easily inserted into the longitudinal grooves 51 of the profile rail 50. Due to its elasticity, the cover 40 returns to its original shape after the insertion area, in which it stays in the longitudinal grooves 51. Alternatively or additionally, especially with profile rails 50 made of sufficiently elastic material, the roller 30 can also be used to elastically widen the area of ​​the profile rail 50 in which the cover 40 is inserted in the area of ​​the insertion 71 in order to facilitate or enable insertion. Especially, for example, with a correspondingly widening geometric design of the rail guide 35 on the roller 30. In another,In the non-illustrated embodiment of the invention, the cover 40 can be deformed by the roller 30, instead of the deformation shown with its belly facing downwards - toward the profile interior 57 - in the opposite direction, with its belly facing upwards - away from the profile 50. In the preferred embodiment, the cover returns to its original cross-sectional shape, for example, flat, after insertion and reversal of the elastic deformation. In special embodiments, at least part of the concave or convex deformation of the cover can be retained.For example, by ensuring that the cover remains firmly clamped in the profile and cannot fully recover. For example, this can also be used to achieve different radiation characteristics of the light strip (using the same cover material). The roller 30 can be specifically designed for a single or multiple different profiles 50 and / or for a single or multiple different covers 40 – specifically with regard to the shape of the rail guide 35, insertion nose 36, and / or guide elements 34. In one embodiment, the roller 30 according to the invention is also used as an "unroller" in that, in an analogous manner, the cover 40 can be removed from the profile 50 onto an empty roll 31 with an opposite movement 70. Not shown here for the sake of clarity, the roller 30 can optionally also be provided with a separating or cutting device for the cover 50. This is preferably arranged in the area of ​​the insertion nose 36.for example, with a blade, a knife, or scissors, either on the roller 30 itself or on a guide device for external separating or cutting devices. Alternatively or additionally, a cutting marking device can also be provided. This allows the cover (40) to be cut, severed, scored, or marked to the same length as the profile upon reaching the end of the profile. Fig. 4 again clearly shows the deformation 41 of the cover 40 with the roller 30 according to the invention in the exposed insertion area 71. This is specifically caused by the insertion nose 36, specifically by its shape and arrangement, which causes an elastic deformation of the cover in the insertion area. For example, the insertion nose 36 is deeper in the area of ​​the profile center than the lateral rail guide 35 or 35b, which rests on the profile 50, so that the cover 40 is deformed.specifically according to the shape of the insertion nose 36. The contact force 71 shown in the previous figure is supportive, as it acts downwards via the insertion nose 35 in the central cross-sectional area of ​​the cover, whereas the lateral supports of the cover 40 on the profile 50, especially in the area of ​​the longitudinal grooves 51a, 51b, cause upward counterforces, so that the cover 40 bends elastically and, due to the resulting bending radius, becomes smaller in width, so that the cover 40 can be easily inserted or clipped into the longitudinal grooves 51a, 51b. In particular, the interaction of the insertion nose 36 with the guide element 34 as a counterholder and / or the rail guide 35 as a positioning aid is advantageous, in particular for the advantageous definition of the deformation 41 and position of the cover 40 in the insertion area. In an embodiment with a locking formation on the roller 30, which is designedTo hold the roller°30 independently in the profile rail°50, the forces or counterforces for the deformation of the cover can also be caused or maintained entirely or partially by this snap-in connection. Alternatively, the cover 40 can also be inserted such that the cover 40 is attached indirectly in the profile in accordance with the invention - e.g., indirectly via a connection to an element that is attached in the profile, such as the lighting unit 52. It will be obvious to a person skilled in the art that the embodiments and approaches shown or described here in various figures can also be combined and interchanged differently than shown within the meaning of the invention.
