Description

Mineral wool product

Technical field

The invention relates to a mineral wool product, in particular a mineral wool mat, a mineral wool board, a mineral wool shaped element or the like, consisting of a mineral wool web and / or a plurality of interconnected mineral wool lamellas and in particular one lamination applied to a main surface in the form of a sheet of plastic, metal, glass web, other paper, fibrous webs, sandwich sheets of the same or different materials or the like.

BACKGROUND OF THE INVENTION

Such mineral wool products are known in the art. They are used for thermal and / or acoustic insulation of buildings. In particular, such mineral wool products are used in the insulation of facades and / or roofs. However, other fields of application for such mineral wool products are also known. For example, such mineral wool products are used to heat insulate pipes.

From DE-C-36 12 858 a mineral fiber web existing in the form of a disc, which is cut off in longitudinal sections, the length of which corresponds to the width of the annulus between the rafters, plus an overlap for the clamping effect. In addition, the mineral fiber web has marking lines on the one hand, which are produced by means of a parallel cylinder with line heating zones when producing such a mineral fiber web. However, such mineral fiber products have the drawback that the drawing of the marking lines, which in addition extend transversely to the longitudinal course of the strip, can only be effected by the thermal effect on the mineral fibers. It is disadvantageous that this prior art mineral fiber web is not covered with one-sided lamination. The lamination can also be applied only to a surface which has no marking lines.

Based on this state of the art, the invention has as its principal object to create a mineral wool product which is simplified with regard to its processability, i.e. its identifiability and with regard to the possibility of cutting, which is appropriate in the workplace at the moment. it can be produced cost-effectively.

SUMMARY OF THE INVENTION

The solution to this task is to ensure that the lashing has a marking that is placed continuously at a certain distance parallel to the longitudinal edge.

The mineral wool product thus formed, which is in particular in the form of a mineral fiber strip according to DIN 18165-1, thus has a one-sided lamination having at least one marking. This embodiment facilitates the cutting of the mineral fiber web without the need for suitable measuring tools. Particularly in production, that is to say, when cutting mineral fiber strips to length to insulate the pipe, this results in advantages in terms of processing speed. The term mineral wool product includes insulating felt and insulating mats.

Preferably, the marking is formed as a scale and consists in particular of a large number of lines spaced at equal distances. These scales may be on one or both longitudinal edges of the mineral wool mats. For wide mineral wool mats, the scales may also be closer to the central axis, as well as longitudinal or embossed colored metal foils, sandwich foils, to mark the front edges. The scales may be or may be embossed into the surface of plastic sheets, paper, webs and the like. In addition, scales are possible

According to a further feature of the invention, it is provided that the marks are formed from numbers, letters, pictograms or the like from meaningful features, the height of which is located at right angles to the edge of the laminating to determine the distance. This embodiment has the advantage that not only the dimensioning is indicated by the marking, but also that the marking also indicates other properties of the mineral wool product. For example, manufacturing plants, the type of mineral wool board, mineral wool mats or the like may be mentioned. Dashed lines may be placed between numbers, letters, pictograms or similarly meaningful marks which, in combination with the abovementioned meaningful marks, represent and optionally indicate a scale. Letters, numbers, pictograms or similar signs are vouchers for workers.

According to a further aspect of the invention, it is provided that the width of the distance between the longitudinal edge and the marking corresponds to half the width of the overlapping adhesive strip. For the mineral wool product sections which touch each other when stacked, the visible scales can therefore be covered in an outward direction by means of an adhesive strip. Especially in the pipe insulated by these mineral wool products, a uniform insulating surface is then obtained, whereby advantageous markings would still be visible to the treatment of the insulation or the mineral wool product.

In this case, the adhesive strip is in particular made of the seaming material, so that even with regard to the seaming material a uniform surface is obtained.

According to a further feature of the invention, it is provided that the marking is placed on two mutually parallel edges. The mineral wool product may also be processed at both its longitudinal edges, or the opposing markings may be joined together to make a straight cut perpendicular to the longitudinal edges of the mineral wool product. This makes it possible to cut the mineral wool product to length, for example, for fixing it to a pipe of a certain diameter and thus to a certain extent to simplify the work. Thus, the pipe sheathing can be cut off from the mineral wool web with an exact fit before the sheathing is then fixed to the pipe, whereby the ends of the mineral fiber web extending in the longitudinal direction and touching each other are joined together by an adhesive tape.

It has been found to be advantageous if the laminating is made of a sandwich aluminum foil. Such a sandwich aluminum foil is highly ductile and additionally complements the thermal insulation properties.

it is preferred that the individual marks match the length of the marking. Preferably, the distance between the longitudinal edge and the marks is 10 to 30mm, more preferably 20mm. The markings consist of beams that cover an area of 2.5 to 8mm (preferably 5 to 6mm) x 30 to 70mm (preferably 50mm). These dimensions are so advantageous,

In addition, the distances between the showed area, the resolutions placed on that the marks cover only that which is necessary to ensure good marking.

Finally, the tags may be laminated or may also be knocked out of the lamination. The marks may preferably be color-printed or embossed into the surface of metal foils, plastic foils, paper, webs or sandwich foils. In addition to rectangles, other geometric shapes such as commas, dots, circles, triangles or the like are contemplated. Preferably, such marks are placed on pipes with lengths between 0.5 to 2 m, for boards between 0.5 to 2.5 m in length and width, as well as with mats and lamella mats of 0.5 to 2.5 m in width and 1, 5 to 20m length.

BRIEF DESCRIPTION OF THE DRAWINGS

Further features and advantages of the invention will become apparent from the following description of a preferred embodiment of the mineral wool product of the invention shown in the drawings.

The pictures show:

Fig. 1 shows an expanded mineral wool mat with marks positioned along the longitudinal edge; FIG. 2 shows a section of the mineral wool mat according to FIG. 1, FIG. 3 shows various forms of marking in the region of the longitudinal edge of the mineral wool mat according to FIG. 2 and FIG. 4 shows a pipe insulated with a mineral wool mat according to FIG. Second

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 shows a lamella mat 1 in the deployed position. The lamella mat 7 is of a plurality of lamellae 2, which are arranged at right angles to the longitudinal extension of the lamella mat 1 and are connected together. On the outer surface of the lamella mat 1 is laminating 3 which is made of sandwich aluminum foil. The lamination 3 is connected to the individual slats 2 '.

Marking 5 is applied along the longitudinal edge 4 of the lamella mat 1 for the lamination 2. The marking consists of a scale having a large number of line beams 5. The line beams 6 have a length that corresponds to the distance between the line beams. In addition, the line beams 6 are aligned parallel to the longitudinal edge 4 of the lamella mat 1.

In FIG. 2 shows a cut piece of lamella mat 7 according to FIG. It will be appreciated that the line bars 6 are located in direct proximity to the longitudinal edge 6. The line bars 6 have a distance from the longitudinal edge 4 of the lamella mat 1 20mm. In addition, each J5 line beam is 50mm long and 5mm wide. Accordingly, the interspaces medzi between line beams 50 50 mm are also long, hence marking 5 has common scale characteristics.

In FIG. 3, four examples of possible marking 5 are shown. It will be appreciated that the marking 5 may also be of letters and / or numbers as well as pictograms. The letters and / or numbers as well as the pictograms are always separated from each other by a line bar 6. However, it is also possible for the line bars 6 to be arranged such that the letters and / or numbers are not interrupted by these line bars. It is furthermore possible that no line bars 6 are provided adjacent to the letters and / or the numbers and / or the pictograms. In this case, the letters and / or numerals may also be a possible scale if the letters and / or numerals or the like are of equal size, therefore both their distribution rectangular to the longitudinal edge 4 of the lamella mat 7 and their width parallel to the longitudinal edge of the lamella mat. is created evenly.

The markings may be embossed or embossed or embossed.

By marking 5 on the laminating 3 of the lamella mat 7, a blank is provided for easier orientation in shortening the length of the lamella mat. based on the scale properties. Of course, it is also possible for the marking 5 to be located not only on one longitudinal edge 4 of the lamella mat but on both edges 4 of the lamella mat 7. Furthermore, it is possible for more than one marking 5 to be provided for wide lamella mats 7, for example an additional marking 5 in the middle of the lamella mat 1.

In FIG. 4 shows the use of the shred shown in FIG. 2, the lamella mat 1. Fig. 4 shows for this purpose a pipe 8 which is on its outer side wrapped with cuttings 9 of the lamella mat 1. In this case, the marking 5 can be seen on the lamina mat sections 9 '. These markings run parallel to the longitudinal edges 8 in the circumferential direction of the pipe 8.

Each lamella section 9 'is placed on the pipe 8 so that the front edges 10 (cf. FIG. 2) of the lamella section contact with each other are in contact with the form contacts. The leading edges 10 are then covered with an adhesive tape 11 and joined together.

A further adhesive strip 12 is disposed between two adjacent lamella matte cuttings 9 to connect the adjacent lamella matte cuttings 9 in the longitudinal direction of the pipe 8, thus overlapping the marking 5 of the adjacent lamella matte cut off 9. This produces a uniform, uniform surface without marking 5. The adhesive strip 12 is also made of a sandwich aluminum foil, so it is possible to obtain a uniform, uniform surface on the pipe 8. The width of the adhesive strip 12 thus corresponds to twice the distance between the longitudinal edge 4 and the marking 5, including the width of the bar 6. Adhesive tapes 12 whose width is 50 to 100 mm are preferably used for this purpose.

Instead of the described lamella mat 7, other mineral wool products can also be formed according to the invention. For example, it is also possible to provide the inventive mats in which the fibers are predominantly rectangular on the laminated surface. This fiber arrangement allows high lateral compressibility. The use of the invention is also possible with insulating felt.
