Insulating body, ordering from one made of bonded fibers formed continuous, streaked with longitudinal margins

elastic mat

The invention relates to check an insulating body from a continuous formed from bonded fibers, provided with longitudinal edges resilient mat is _Λ wi # For example, to S _c Hall and heat insulation: is used, "...- ■■ '.-. -, -. ''"■" ■.,. "· -.

In structures made of metal, for example in buildings with Walls and roofs made of corrugated iron are used for interior lining and insulation materials that are moisture-proof and should give the interior an attractive appearance. The roofs of such buildings cause problems excels when insulating mats made of glass wool are used

will. If not the mats at closely spaced points if they are pegged, they tend to sag, which results in an unpleasant appearance. If the lining with these mats is to be moisture-proof, it is necessary to use the longitudinal edges of adjacent mats to apply overlapping strips or the mat edges to glue together. Usually a sealing strip is glued over each joint between the mats.

For insulation purposes, dimensionally stable or semi-rigid boards or mats made of felted fibers are usually used. These boards or mats were previously cut into relatively short lengths for handling and shipping to facilitate. These short mats or panels require a multitude of end connections to make a possible Heat loss is increased j is also one of such Mats formed cladding unsightly. If the mats are provided with a layer of a vapor barrier material and even a decorative paint carry, the required end connections require additional expenditure during installation, although the overall appearance of the fairing is significant is disturbed.

In contrast, the present invention relates to an insulating body made of bonded fibers, which consists of a elastic mat consists of a main surface and a Has longitudinal edge strip and with a flexible Cover layer is provided which overlaps the surface of the mat and an edge strip covering the edge strip of the mat forms. The edge strip parallel to the longitudinal edge of the mat is inherently connected to the mat coincides with the edge strip and protects it from damage and deformation during handling! the handrail The mat is removable to cover the edge trim of the To release top layer when the mat is installed, the edge strip sealingly covering the joint and the edge of the adjacent mat.

The previously existing problems are eliminated by the insulating body according to the invention, since it is maintained its dimensional stability can be rolled in lengths that overlap a plurality of frame elements j the length the insulating body can also be dimensioned so that it overlaps the entire wall height of the building. For example In roof installations, the insulating body extends over the entire length of the roof and has a sufficient length Dimensional stability and strength that it does without sagging can be supported at intervals of up to 2 m.

the "the insulator has one over the edge of the Matte protruding edge strips of the top layer, which is sufficient is stiff to reach over an adjacent mat. This strip will be used during shipping by the Protected edge strip of the mat and reliably maintains its shape, so that when the butt jointing of the Mats forms a practically impermeable seal of the joints between the mats without the application or A special sealing strip is required to be affixed is.

The insulating body according to the invention is preferably used for thermal insulation and consists of a mat made of resin-bonded glass fibers. The * iatte is slit longitudinally a side edge at a short distance from the edge which is initially held by fen slot in position to form the edge strip, wherein the slit is eye forms either continuously or as a perforation. Later, ie during the installation, the edge strip can be removed by breaking it off. The edge strip is at least equal to the width of the edge strip of the cover layer in order to protect it from creasing or other damage. The edge strip remaining in its position forms a protection for the edge strip of the cover layer.

... / 5 209843 / Q74B

The mat is made of heat-insulating glass fibers, slit in the Mngs direction or perforated to achieve the actual mat and an edge strip parallel to the mat edge, with a top layer being applied to the mat which covers the edge of the mat, the edge being an effective protection for the mating with it Forms edge strips of the top layer.

The edge strip can be reinforced by the fact that a. corresponding part of the Dekcschicht folded around itself will; An additional band can also be used as reinforcement Width can be used. In the latter, the mat is layered with the thin flexible dock and connected to the additional tape. The top layer and that '' additional tape is applied to the mat at the same time, the tape between the cover layer and the mat in register with the one previously slotted in the mat, * The combination of mat, top layer and additional tape formed in this way is in one Oven cured to set the adhesive and then on wound a core of sufficient diameter to prevent the mat from being permanently deformed, so that they unrolled again while maintaining their flat shape can be. Since the tape is impermeable to the adhesive, it keeps the cover layer from the edge

bar separately, making the sidebar without difficulty can be severed along the slot when the edge strip of the facing is exposed for installation must become. Here, the additional band on the underside of the cover layer overlaps the mat by a small amount Amount. The tape serves as a reinforcement for the edge strip of the top layer.

In the case of the insulating body according to the invention, the application under the gluing of strips to form a vapor barrier superfluous. A creasing of the sand strip is prevented by the removable edge strip protecting it, so that when it is installed, the cladding will look flawless. The! Shape resistance of the Due to its relatively high density, mat prevents sagging and makes handling easier. That Appearance of the cladding is also improved, as the smooth protruding edge strip of the top layer is barely noticeable is.

The edge strip reinforced by the tape 4-0 serves as a seal Completion when the mats 24 are installed side by side butt. For shipping, the mat 24 with her Edge strip 54 wound around a core 46 to form a roll 28 and is easy to handle in this way during shipping.

Even if on the production line, a fiberglass mat is preferred 24 is produced, other materials can also be formed into fibers, for example by the usual spinning, by drawing, by chopping or by blowing. The glass fibers 12 are made of glass thread comminuted by softening by means of a spray flame 14 into individual fibers of greater length 12. The union of the Fibers 12 on chain 18 form a mat on which endless chain rotates around rollers 48 The binder applied to the fibers 12 by the spray nozzle 16 has sufficient binding force to seal the fibers to unite in a loose mat. The mat 24 is then passed through the heated rotating rollers 20 where the surfaces of the mat 14 are hardened by the heat of the rollers.

The opening formed by the parallel inner surfaces of the opposed sheets 22 is conveyed, the sheets 22 of the mat being given the desired thickness and the latter being hardened in order to maintain its shape and to give it the required strength. For the purposes envisaged here, tightnesses in the range of 20 to 40 kg / m * were used with thicknesses of 2.5 to 7.5 cm using a sufficient binder to prevent the mat from sagging when it is used at intervals of, 12 m is supported. The division of the mat 24 into a main part 52 and an edge strip 54 »which is easily removable * is carried out with a slotted circular knife 27 which works together with a counter roller, not shown, in order to create easily separable bridges 53 between the parts 52 and 54, as shown in FIG. :

Even if glass fibers because of their easy and economical manufacturability in small diameters and corresponding Lengths can be drawn, other known materials can also be used, which are produced by spinning, drawing, Crushing, blowing and the like can be broken down into fibers of small diameter, which can be wholly or partially used Formation of the mat can be used.

A thin pliable cover layer 36 is over onto the mat its entire width from a roll 38. applied as is shown in FIG. Typical cover layers 36 of this type consist of non-plasticizing films or foils, such as chlorinated polyethylene or polyvinyl chloride However, other moisture-proof films can also be used or movies are used. An adhesive bath 30 with a the adhesive in excess promoting roller 32 transfers a coordinated amount of adhesive on an application roll 34 * which applies the adhesive to the inner surface of the cover layer 36 transmits before this on the KoHe 44 with the additional Band 40 is combined, which may be made from a more pliable vinyl product. The tape 40 reinforces the edge strip 60 and prevents the edge strip 54 from sticking to the Cover layer 36. The tape roll 42 conveys the tape 40 onto a pressure roller 44 'which, as it rotates, forms the cover layer 36 and the belt 40 on the mat 24 brings to the plant. The hardening of the adhesive connecting the cover layer 36 with the mat 34 and for connecting the cover layer 36 with the tape 40 is done by heating in an oven 58. The edge strip 40 is not glued to the cover layer

36 or the band 40 connected. The now finished insulating body with the cover layer 36 and the tape 40 is on a Core-4-6 wound, which is driven in the usual way with the front end of the mat 24 being attached to the core. The smallest winding radius is big enough to prevent permanent deformation in the mat .24, so that the mat 24 resumes its level lOrm when it is unrolled. The mat comes in longer lengths, for example wound into rolls 28 over 25m. what when unwinding the Mat 24 is cut in the transverse direction by conventional means, for example by scissors. If the mat 24 is unwound from the core, the front edge of a: new mat is attached to the core 46 in order to manufacture to continue. The edge strip 54 · is first in its Position under the edge strip 60 either by friction or held by its association with the mat, or by both. When the edge strip 54- is severed, the friction of the belt alone is usually enough to achieve to hold the skirting board in place. The sidebar protects the edge strip from deformation as it supports it. This is important in packaging, for example when rolling up and in the following handling and Roll out. The edge strip is removable by hand to expose the edge strip so that it is opposite the edge protrudes from the mat. "

The manufacture and use of the mat 24 equipped with the cover layer 36 and the tape 40 can be easily understood with reference to FIG are cut away for explanation. The main part of the mat 52 in a thickness of 2 ;, 5 c ^m and a density of 20 kg / nr has a

(1 mm)
4 mil / unplasticized chlorinated topcoat

( 0.75 mm) of polyethylene and a tape of 3 mil / pigmented vinyl and only sags by 5 b ™ when it is supported at intervals of 1.50 m due to the strength given to the mat by the plates 22. Due to the strength of the main part 52 of the mat, the hand strip 60, which is formed by the protruding tape 40 and the cover layer 36, is supported when the edge strip 54 of the mat 24 is broken off along the edge 62. The tape 40 has the advantage that it is impermeable to the adhesive of the cover layer 36 and separates the edge strip 54 from the adhesive layer, so that the edge strip can be removed without difficulty. The tape 40 overlaps the main part 52 of the mat and is attached to the cover layer 36 by adhesive bonding and forms a reinforcement of the edge strip in the transverse direction, as well as in the longitudinal direction of the mat 24.

The edge strip 60 is replaced by the edge strip that has been removed 4-0 protected from bending or creasing, as the edge strip remains connected to mat 24 until installation. As FIG. 12 shows, the edge strips 60 a leak-proof barrier between the mats arranged next to one another is achieved in a simple manner if this Be laid end to end. It is important that the Edge strip 60 remains in its flat position until it is laid in order to serve as a conclusion. In addition, the flat edge strips 60 a clean appearance, since it hardly appears.

The reinforcement band 40 is preferably made of "'plasticized em vinyl that goes with the stretching of the top layer 36, so that creasing of the cover layer 36 and the tape 60 is avoided. Other flexible ones can also be used for the band 60 Materials are used.

The mat 24 can also be manufactured in widths greater than 1.50 m are used, with thicknesses of 2.5 to 7 »5 cia even if a thickness of 4 cm is preferable.

The dimensional stability and thus the bagging of the mat 24 changes with its thickness and density. A typical density is around 20 kg / nr. Since the dimensional stability with

2098A370 7 45 *,

as the thickness increases, the density can be changed, to obtain a certain dimensional stability.

In addition, a second edge strip can be attached to the tapes of the Mat can be provided if so desired. A mat with two edge strips can be used in a similar way with the known mats are used by placing the adjacent edge strips of adjacent mat along the edges to be contracted.

The widths of the edge strip 60 and tape 40 are variable, widths of 6.5 cm are preferred, with the band partially overlapping the main part 52 of the mat 24 has a width of 7.5 cm.

Fig. 6 shows a roll ready for dispatch with the rolled up Edge ridges. Fig. 7 shows the position of the rolled edge strips 5 ^ -, which rest against the edge strips 60 to to protect them.

As a result, of course, the appearance and the sealing of the joints between adjacent mats is adversely affected .

Vie said before, is the sagging of an insulating body, which is supported at intervals of 1.50 m, is small and is in the range of 0.5 cm. Through the reinforced Edge strip 60 sags less so that it rests more closely on the adjacent mat.

The advantage of the belt 40 has been described above. Modified embodiment of the edge strip 60 is shown in FIG 11A shown with a portion of the cover layer 36 around it itself is folded back for the purpose of reinforcing the edge strip and preventing it from sticking to the Edge strip 5 ^ or 5 ^ '· With this embodiment In the production according to FIG. 1, the strip 40 running off the roll 42 is omitted and the cover layer 36 has at its edge has a portion that after application of the adhesive and before contact with the mat 24 around itself is folded. Since the cover layer is impermeable to the adhesive, no adhesive comes with the fibers of the Edge strip 5 ^ or 5 ^ 'in contact, so that an effortless separation this sidebar is possible.

The advantages of the insulating body according to the invention lie in its dimensional stability, in the possibility of curling for transport and in the protected edge strip 60 described above. The application previously required there is no sealing strip on the joints between the individual wadding * The smooth and flat one Edge strip 60 forms an effective moisture barrier by simply overlapping it with an adjacent one Mat 24 · formed joint. The need for additional supports to prevent sagging as with the known mats to prevent is also omitted. The edge strip 60 closes the joint "existing between the mats" and awakens the impression that a series of laid mats 24- forms a single smooth surface. Handling the Wadding 24- is made easier by its dimensional stability.
