direction on the whole stretched and the wrapped bar in predetermined position is fixed, with the tensioning made by means of a winch acting on the bracket the material web is stretched in the longitudinal direction and the subsequent tensioning in the edge areas as well hand-wound in the transverse direction around a strip

takes place, according to patent (patent application P 22 29 889.1),

Furthermore, the invention is directed to an apparatus for carrying out it directed this procedure.

The procedure after the main registration has changed in de? practice proven and also the device described in the main application for performing the method enables a problem-free honing.

The object of the present invention is to provide the method and in particular also the device according to the main application To further improve and in particular to simplify the assembly even more, the replacement is already tensioned Facilitate coverings while eliminating any risk of damage to the tensioned coverings and the holding means to simplify the design of the tensioned tracks despite the functional improvement.

Essential features of the method according to the invention are that the material web to be braced wrapped strips are introduced into profile holding receptacles in such a way that the wrapped strip on the one hand Fixed in position in the tensioning direction by means of a blocking element is and on the other hand rests against a tilting of the bar around the blocking element preventing stop.

It is important that the strip wrapped with the material to be clamped only in the profile holding receptacles must be inserted and then the required fixation results practically automatically, since for

409884/0607

2332689

Fixing the material web tension is exploited. on this way, fastening operations such as nailing, Shooting and the like, superfluous, and the insertion and removal of the strips wrapped in material from the holding fixtures can be used without any problems and, above all, without any risk of damage to the material multiple replacements, e.g. for cleaning purposes.

The insertion of the wrapped strips into the profile holding fixtures can be done by hand, but also using a hand-operated jig.

The wrapped strip is preferably inserted into the profile holding receptacles in sections and using strips that are subdivided or divisible in pieces. In this way, it is possible to bring the strip wrapped with the material to be tensioned by machine tensioning just in front of the profile holding receptacle and then manually remove an approximately 10 cm wide strip from the tensioning device and · *> ™ by hand or with a small spatula into the profile holding fixture, in which the covering is then fixed by self-clamping.

Another advantageous method feature of the invention is that during the tensioning process between Tension lining and the tree located on the ceiling or wall is heated. Compared to the previous method in which the Whole tree was raised in order to brace a ceiling, now only a tree with a very small height has to be can be heated by about 2 cm, which requires less energy, achieves faster heating and above all work is made easier for the assembly staff, since it is no longer at elevated and the work hindering Tree temperature must be active.

A particularly advantageous embodiment of a device for performing the method according to the invention is characterized are characterized in that the strips to be wrapped are essentially rectangular in cross section and that the profile holding receptacles are formed by dimensionally stable rails, each consisting of a receiving the wrapped strips, im essential U-shaped rail part and a fastening part combined to form a unit via a connecting web exist.

It is particularly advantageous that only one fastening of the profile holding receptacles on the respective wall of the ceiling is required and no further fastening operations are required after these holding receptacles have been fastened are, because the covering to be tensioned only has to be inserted into the Hai te recordings and through them Cladding is held. In In this context, that the profile retaining seat not only takes on the fastening functions for the tensioned covering, but is used at the same time as a finishing and viewing strip.

The cross-sectional shape of the strips is preferably elongated and rectangular, and these strips are expediently made made of hard fiber strips. This makes it possible to initially use continuous hard fiber strips and for the immediate Insertion process in the profile holding fixtures of strip parts break off a suitable length and in this way carry out the insertion process that is going on in sections.

It should also be mentioned that by clamping the stretch ceiling in place, it can also be dismantled at any time the ceiling is made possible, with no risk of damage to the clamping surface is given. The more-

409884/0607

often mentioned clamping of the ceiling to be tensioned leads also to the fact that the assembly can be carried out more time-saving, since it is no longer necessary that a Person stretches the ceiling and another person carries out the process of shooting the respective strips. According to the present invention, after the ceiling has been tensioned in the main tensioning direction, the Side bracing carried out by a single person which results in a considerable reduction in assembly time.

Another advantageous embodiment of the device according to the invention is characterized in that the U-shaped Rail part has a base surface, the width of which corresponds approximately to the width of the wrapped bar that the both legs extending from the base area have a height corresponding approximately to the thickness of the wrapped bar and that a stop for the wrapped strip is provided opposite the base surface. This creates a Receipt for the wrapped bar, which ensures problem-free and easy clamping of the wrapped Bar allowed and at the same time guaranteed a perfect view.

The stop is preferably formed by part of the connecting web. This double use of the connecting web leads to a structural simplification.

Another particularly advantageous embodiment of the invention is characterized in that the U-shaped rail part has a base surface, the width of which is at least the same The thickness of the wrapped bar is that the two legs extending from the base surface are about the same width as the wrapped Bar have the appropriate height, and that this U-shaped rail part can be pivoted and fixed to the connecting web connected is.

409884/0607

On the one hand, this configuration in turn ensures that the wrapped strip is held in a favorable manner and on the other hand, the swiveling and fixable coupling of the connecting web and receptacle enables the clamping process and also facilitates a possible dismantling, since in this case the strip wrapped with the clamping lining would be can be introduced particularly easily into the receptacle and then by simply folding over the swiveling veil the required tension is achieved. This also enables corner, door and window connections to be extremely clean to be provided with the bracing, whereby the actual tensioning bar is no longer visible after it has been folded down is.

At its free end, the connecting web preferably has a substantially cylindrical bearing bead with a protruding locking web, this bearing bead from The bottom part of the U-shaped rail is encompassed with play and the corresponding recess in the bottom part is one of the hasty webs Has adapted groove.

The overall rail is advantageously made of metal and preferably of aluminum.

This choice of material always produces clean and smooth finishes due to the resulting stability and enables the fastening points to be much further apart than in the case of the previously known strips. This also results in a simplification of the work which, viewed overall, can achieve up to 50% of the assembly work that was customary up to now.

409884/0607

Another advantageous embodiment of the invention is characterized in that the profile holding receptacles are formed by dimensionally stable rail parts, which are preferably made of wood with mutual spacing Carrier strips are attached.These are spaced apart Rail parts practically have the function of clips, with each rail part being clamped to the Material wrapped strips, or strip ends can accommodate. Besides the fact that on this Way an optimal use of the available rail material is made possible, proves with This embodiment is advantageous in that the assembly is made much easier and also the replacement of the clamping lining can be made without difficulty, since the strips wrapped with the web to be tensioned in particular are particularly easily accessible and manageable in the areas between the rail parts.

A viewing strip can preferably be clamped to the rail parts. This creates a visually perfect finish Guaranteed with a corresponding shadow gap to the wall, since it is no longer visible from the viewing area it can be seen that the profile holding receptacles are not made up of continuous rails, but only of individual ones consist of mutually spaced rail parts.

A particularly advantageous further development of the method according to the invention is that as to be braced Material web a glass silk fabric is used, the back of which is at least partially covered with a plastic film, in particular a PVC film, is laminated. The seam is expediently designed as a scissor seam. Because of the lamination of the fiberglass fabric with a plastic film enables high-frequency welding,

409884/0607

the plastic liquefies during this welding process and an absolutely solid connection is then established results. It is particularly advantageous with this type of mutual connection of individual tracks that one Optically very smooth connection is obtained, which is also extremely tear-resistant. There is another advantage of PVC lamination in that the aiysich relatively unstable glass textile fabric is stabilized in its area, which has a particularly favorable effect in the intended application, that you can also ensure an extremely straight tension seam.

Another way of achieving a good seam join is that for example in the gap seam, an adhesive, preferably a synthetic resin dispersion is applied, and then, for example, at temperatures of 110 to 14-0 ⁰ C, carried out a welding operation. This welding process can also be carried out using high-frequency welding devices.

The invention is explained in more detail below on the basis of exemplary embodiments with reference to the drawing; in the drawing shows:

FIGS. 1 and 2 are schematic representations for explanation the fastening device according to the invention,

3 shows a basic illustration of the device

according to Fig. 1 to explain the fastening process of a stretch ceiling,

FIGS. 4 and 5 are schematic representations of a further Embodiment of the device according to the invention, and

409884/0607

6 shows a schematic representation of a further

fastening device according to the invention.

Fig. 1 shows in the form of a section a corner transition between a ceiling 1 and a wall 2, in this Corner transition one marked with the general reference number 3 Fastening device for a ceiling covering 4 is attached.

The edge area of the ceiling covering 4- is around a strip preferably consisting of a hard fiber strip 5 wrapped, and this wrapped bar 5 is in a U-shaped receptacle attached, which from a base part 10 and two of this base part 10 outgoing Legs 11, 12 is formed. The width dimension of the base part 10 corresponds essentially to the width of the wrapped bar 5 "and the height of the legs 11, 12 is essentially the same as the thickness of the roll introduced. The leg 11 facing away from the wall 2 is preferably formed somewhat curved in order to create the most suitable receptacle possible for the roll, and this leg 11 fixes the covering 4 in Spannrichtung.TJm tilting of the roll around the leg 11 due to the

409884/0607

To prevent existing tension is in the area of the wall side Leg opposite the base surface 10, a stop 15 is provided, which is advantageously of the connecting web between the receptacle 10, 11, 12 and the fastening rail 6 is formed. The fastening rail 6 advantageously has fixing- and / or spacer bars 7 and can be fastened to the ceiling 1 by means of fastening bolts 8.

The free end 14 of the connecting web 9 lies on the wall 2 with the formation of a shadow groove 13 in cooperation with the leg 12 on. As shown in FIG. 1, the base surface 10 forms together with the associated legs 11, 12 at the same time a flawless end and viewing strip and thus no need to attach any additional cover strips.

In
/ Fig. 2, the fastening device or overall rail according to FIG. 1 is not fastened to the ceiling 1, but rather to the wall 2. This variant shows that the tensioning of a material web 4 can take place not only parallel to the base surface 10, but also perpendicular thereto. With regard to the jamming of the wrapped strip 5, there are no significant differences. In this type of installation, however, not only the receiving part 10, 11 and 12 but also the connecting web 9 act as a sight strip.

Fig. 3 serves to explain the assembly and shows the introduction the wrapped bar 5 in the holding receptacle below Use of a tensioning spatula 24, which only has a U-shaped receptacle for gripping the wrapped strip 5 and serves to keep relatively short sections of the wrapped Insert the bar into the receptacle.

409884/0607

FIGS. M and 5 show an embodiment variant which is characterized in that when the covering is tensioned, no tensioning strips, covers and the like are visible any more.

In this embodiment, the U-shaped rail part has a base surface 23, the width of which is at least equal to that of The thickness of the wrapped strip 5 is, and the two legs 21, 22 extending from the base surface 23 correspond to FIG their length about the width of the wrapped bar. It is essential that this U-shaped rail part 21, 22, 23 in the bottom part 19 has a recess which has a bearing bead 17 provided on the connecting web 16 in such a way with play encompasses that this U-shaped rail part around the Lageswulst is pivotable. On the bearing bead is now a locking web 18, which can be made in one or more parts, provided which cooperates with a groove 20 provided in the recess.

M shows the arrangement after the wrapped strip 5 has been inserted into the U-shaped receptacle, but before the covering 4 is finally tensioned. It can be seen that the groove 20 and the locking web 18 are not in engagement. If the pivotable, U-shaped rail part is now pressed against the ceiling 1, the covering M- is tensioned on the one hand and the wrapped strip is clamped in the U-shaped receptacle on the other hand. If the U-shaped receptacle reaches a position essentially parallel to the ceiling, the locking web 18 snaps into the groove 20, which results in a perfect position fixation between the U-shaped receptacle and the connecting web 16.

Suitable choice of the distance between the fastening device a desired shadow groove can be obtained from the respective wall. It is accordingly made with a single jig get a proper attachment of the respective covering, without any parts of the clamping or Fasteners would be visible. It is also essential

A09884 / 0607

that by notching the connection between the locking web and the groove The tensioned covering can be released at any time, with no covering damage whatsoever.

It can thus by means of a single tensioning device or tensioning rail designed according to the invention Type of ceiling and wall bracing are carried out, whereby at the same time a simplification of assembly, a facilitation of possibly desired dismantling for replacement or cleaning of the tensioned lining and an increase in the accuracy of the clamping lining attachment results.
