Description

Marks to facilitate cutting on mineral wool products

Technical field

In particular, the invention relates to marks on mineral wool sheet products, in particular mineral wool layers and / or upper parts thereof, which serve to assist in their cutting or orientation as well as to identify them.

BACKGROUND OF THE INVENTION

Particularly in the case of so-called clamping roofing boards, uniformly repeated cutting lines (lines) are known which, when viewed from the longitudinal view of the insulating material layer, are arranged at regular intervals, for example 100 mm, transverse to its longitudinal direction. These known cutting lines are formed using hot air nozzles causing local heating and corresponding fired markings on the surfaces of the insulating material layers. These marking lines are mainly intermittent. In these cardboard marking lines offer the consumer assistance in cutting. Especially when the insulating material layers are used for insulating rafters, where different distances between them have to be taken into account, after measuring the rafter gap, a portion corresponding to this gap is cut from the insulating material layer and placed transversely to the rafter into the gap between rafters. This insulation of the rafters has established itself to a considerable extent on the market, and the laying is carried out essentially by removing the roll

cuts the sheet material, which is then inserted between the corresponding rafters with the correct compression fit and then held in position by the pulling effect.

The other embodiments described herein are based on the fact that there is increasingly an attempt on the market to individualize own products also by means of marks, but it is nevertheless necessary to maintain the suitability of these marks as cutting and orientation aids. In addition, the aspect of universality must also be taken into account, ie, mineral wool products are used in other applications, not only usually, but must be ready and ready for other applications where, for example, cutting and orientation aids have to be made usable in other directions, for example for cutting triangles or geometric shapes.

SUMMARY OF THE INVENTION

The invention is characterized by the features contained in the independent claims, further preferred embodiments follow from the features set out in the dependent claims. As a solution, the present invention provides the following marking variants in which the marks may be applied or performed by hot air nozzles, but also by dyeing or other means and methods. Preferred embodiments are further explained, by way of example only, with reference to Figs. 1 to 11.

for the sake of simplicity only, the respective structure (assembly) is shown only on a portion of the illustrated layer of insulating material. Of course, the patterns are located in corresponding gaps along the entire length of the insulating material layer.

DETAILED DESCRIPTION OF THE INVENTION

The embodiment of FIG. 1:

The mineral wool insulating material layer 10 shows modular (uniformly repeating) marks along the length of the insulating material, where these marks are shown only over a portion of its length, by the type of marks and / or cutting lines 2 arranged at an angle and longitudinally direction of the layer of insulating material and also with spacing between them.

In the illustrated embodiment, three cutting marks 2 are shown across the width, preferably two correspondingly arranged from each longitudinal edge and the third cutting mark being arranged in the area in the middle of the layer of insulating material.

In this embodiment, the upper and lower ends of the cutting marks of the same length, which when connected to each other by a straight line, are arranged on a common imaginary transverse axis perpendicular to the longitudinal edge of the layer of insulating material; these on the one hand serve as cutting aids for cuts perpendicular to the longitudinal edges of the layer of insulating material, but also as a tool for cutting diagonal cuts.

Of course, more than three marks for cutting can be provided across the width of the insulating material layer, which have been selected as being particularly suitable in accordance with given insulating material layer widths.

The embodiment of FIG. 2:

Here, too, the marks 2 are, for example, arranged only in the lower surface, where, as in all other modifications, it must be assumed that they are arranged in a modular manner, i.e. uniformly repeating over the entire length of the mineral wool product, here the insulation material layer.

The marks 2 are formed by geometric patterns and shapes, in particular squares, triangles, rectangles, polygons of any form, which are arranged periodically or modularly, along and across the layer of insulating material, i.e. transversely to its longitudinal extension and in its longitudinal direction.

Here, in the case of marking, the squares of the sides of these squares extending transversely to the longitudinal edges form an aid for cutting and orientation. These squares give an optically favorable appearance and also allow adequate coloring in which these squares can also be used for product and manufacturer information.

The embodiment of FIG. 3:

This solution is similar to that shown in FIG. 2 with respect to the arrangement of the markings required and / or formed in the group at the points of the shaped bodies. These point-shaped arrangements or points 2, when one is connected to another and across the imaginary lines, form parallel longitudinal lines and parallel transverse lines; the longitudinal lines extend in the direction of the longitudinal extension of the insulating material layer and the transverse lines then perpendicular thereto.

The point-shaped arrangements 2 serve here as an aid for cutting once in the longitudinal direction and once in the transverse direction, but also in the diagonal direction, as symbolized by the imaginary intersection line 3. Such diagonal cuts occur more frequently when used on roofs.

The embodiment of FIG. 4:

This fourth solution is characterized by a variant of different tagging groups, here in total two groups that are repeated regularly.

The first group of markers is comprised of cutting marks 2a extending in the longitudinal direction, the upper or lower ends of which lead to an imaginary line across the longitudinal extension of the insulating material layer and to this extent allow a cross-section whose orientation permits longitudinal cutting. Between the two groups of cutting marks 2a, each consisting of three rows on top of each other, are arranged diagonally with nr Ah □ hn ή nr> J-LC, resam marks 2b, the lower ends of which also form imaginary transverse marking lines, but which also allow a diagonal cut as shown by the imaginary intersection line 3.

Also, if the cutting marks 2a are shown respectively in the transverse direction in three rows one on the other and three rows of cutting marks 2b, the number of cutting marks and their rows may of course vary. This also applies to the number of group variables.

The embodiment of FIG. 5:

The modification of FIG. 5 again shows geometric patterns side by side in the transverse direction, here three trapezoids 2, and in rows one above the other, where the geometric patterns due to the lines in the longitudinal and transverse directions of the insulating material layer allow particularly transverse and longitudinal sections; however, the obliquely extending lines, i.e. the lines extending at an angle to the longitudinal direction, also allow diagonal and bevel cuts.

The embodiment of FIG. 6:

In this embodiment, the marks are again determined by the geometric patterns 2a and 2b, which differ from each other but repeat. This embodiment again allows oblique cuts as well as wedge cutting and the like.

The embodiment of FIG. 7:

In this embodiment of FIG. 7, the obliquely extending marks 2 are in the form of beams or flags. This kind of geometric pattern can often be found as a business label, so that these geometric patterns include the business label on layers of insulating material or other mineral wool products in a product-specific manner and at the same time serve as an aid in cutting and orientation. Of course, it is also possible to alternate these brands, especially regularly, so that it is also possible to change the geometric form and the company label or product information. Here, for example, the letters of a business name or its entire name may be contained in uniformly repeating marks.

The embodiment of FIG. 8:

The marks of FIG. 8 are characterized by crossed marks for cutting 2a and 2b so that different diagonal cuts but also transverse and longitudinal cuts are possible as a result of the regular arrangement of the ends of the cutting marks aligned in alignment with one another.

The embodiment of FIG. 9 to 11:

Embodiments of embodiment 9 are characterized by point-like or geometric pattern 2 marking, or by cutting marks 3, or by continuous transverse marking • 9 9

The modification of the embodiments shown in FIG. 9 below, adjacent to the longitudinal edges, includes marks 2 arranged one above the other and aligned in an axis. Here too, transverse, longitudinal and diagonal cuts are possible.

The middle modification of FIG. 10 shows marks for cutting 3 extending in the longitudinal direction, where transverse, longitudinal but also diagonal cuts are again possible.

The modification shown to the right of FIG. 11 shows continuous marking lines which enable cross sections in particular.

The above-described embodiments are claimed individually and in connection with each other with their characteristics.
