Definitions
- the invention relates to a method for Manufacture of mineral fiber products with compacted Surface areas where an endless mineral fiber web is moved continuously the fibers of the mineral fiber web due to a previous manufacturing process essentially parallel to the big ones Surfaces of the mineral fiber web run and the mineral fiber web is an uncured binder contains, which is heard with a heat treatment.
- a method of the aforementioned type and a device is to carry out the procedure above all through Canadian Patent 1,057,183.
- This partial web will then stand out from the rest of the remaining mineral fiber web and pressed between pressure rollers and thus condensed.
- This densified partial web will then returned to the rest of the mineral fiber web.
- the invention has the object Basically, a process for making mineral fiber products with densified surface areas or -to create layers, through which high tear strength and an intensive fiber composite can be achieved can.
- the object is achieved according to the invention achieved that at least one surface area of the endless and continuously moving mineral fiber web with unchanged fiber direction after a first mechanical pre-compression Needle punches up to a predetermined penetration depth is exposed so that the fibers become matted and at the same time the surface area is compressed.
- the stroke frequency of the needles in relation to the usual Conveying speed of the mineral fiber web provides an important factor for both the degree of compaction as well as for matting.
- the production for plate material can be done at increase the constant conveying speed, that the mineral fiber web after curing of the binder in a cutting plane parallel to the large surfaces is cut open, so that two Mineral fiber boards with one side compacted layer arise.
- a matting between the compacted surface layer and the uncompressed mineral laser layer can still be favored and the Tear strength that treatment with different needle types or needle shapes.
- the thickness of the compacted layer in the surface area by choosing the depth of penetration of the needles, by the stroke frequency and determined by the needle shape becomes, such that on the one hand shallow depths of penetration, high Stroke frequencies and needles with great effectiveness Cross section result in thin, highly compressed layers and on the other hand large depths of penetration, low stroke frequency and small cross-section needles thicker, less densified layers result.
- a plate-shaped end product which is a hard and pressure-resistant surface layer owns, so you can do this in easier Achieve that by adding additives by hollow needles for additional reinforcement of the Surface area are introduced.
- additives can sort of like after curing small stamps work. But you can also in the way be injected into the area between penetrate the neighboring fibers and thus one even greater cohesion within the densified Provide surface layer.
- the additives can but also down to the uncompressed mineral fiber layer be introduced, so that in addition to the matting in the area between the compressed and the uncompressed layer numerous additional Anchoring can be achieved. It remains with these Products, as with all others after Products producible according to the method of the invention get the advantage of having good vapor diffusion ability given is.
- a Paint or other coating should be, it is advantageous that a thin fleece a fiber material, preferably made of glass fibers laid on the surface of the mineral fiber web and then the needle pushing operation is carried out so that some of the nonwoven fibers are embedded in the mineral fiber web becomes.
- the thin fleece or the Tissue can also be made from another fiber material exist as mineral fibers, such. B. made of plastic fibers, Textile fibers or metal fibers.
- one 1 is a mineral fiber web 1 in the direction of arrow 22 between endless Conveyor belts 2 and 3 with a certain thickness continuously fed.
- the mineral fiber web comes from a known, not drawn collection chamber, in which the mineral fibers produced are reflected Add a binder on an air permeable Store the conveyor belt in one layer.
- the mineral fiber web will then be proportionate at first loose condition between the two conveyor belts 2, 3, which are guided around pulleys 4 and 5, held. Then there is a certain somewhat exaggerated drawn pre-compression of the mineral fiber web between Pressure rollers 6, 7 to 8, 9 or between accordingly arranged and guided conveyor belts.
- the mineral fiber web can run in this path first conveyor section very homogeneous mechanical pre-compact until a pre-compacted mineral fiber web 10 of a predetermined thickness.
- the mineral fiber web 10 pre-compressed in this way arrives then into a compression and matting device, which is shown in simplified form in FIG. she has a plurality of needles 13 in groups or connected together with a lifting device is a high frequency in the direction of arrow 15 Performs lifting movement.
- a lifting device is at least on one surface side, either on the top or bottom, the mineral fiber web 10, 17 arranged and with a linear actuator, not shown Mistake.
- the needles 13 attached to a plate-like carrier 11. This plate-like carrier is with the lifting device and the drive, so that the Needles cyclically up to a predetermined penetration depth in the surface area of the mineral fiber web 10, 17 penetrate and this in the preselected surface area compress and matt at the same time.
- the stroke of the lifting device is advantageous adjustable and adjustable to a certain height and the stroke frequency can be regulated via the drive. It is also advantageous if the impact forces of the needles 13 are adjustable. By limiting the impact forces the compression needles can be prevented if unwanted wool inclusions occur deform within the mineral fiber web, so that reduces the risk of the needles breaking off becomes. In practice, these can be explained Settings and regulations in a simple way manage that the lifting device is pneumatic or can be operated hydraulically.
- the needles 13, in particular those of compression serving compaction needles, have a chisel-like widened head 27 or 30 according to the figure 2 and 3 formed at the end of the needle shaft 26 and 29, respectively are.
- the needle head 27 has at the lower end a cutting edge 28 which, when striking the fibers force them into a loop shape and thus matting with the neighboring fibers.
- a protruding downward Needle tip 31 is provided in which Embodiment of the needle according to Figure 3 is on the chisel head 30 a protruding downward Needle tip 31 is provided. Instead, too several needle tips can be arranged.
- the needle tips have small lateral ones Hooks 32 and 33 that cause further deformation and Matting of mineral fibers leads, above all in the border area between the densified surface area on the one hand and the uncompressed Area of mineral fiber web.
- the same goal of Matting and connection between the two aforementioned Layers serve a different design, after which at least two different needle groups, namely a group of short front needles and a group of longer needles are.
- the needles or plungers have a larger one Diameter and, as shown in Figures 2 and 3, others Forms, such as in multi-needle sewing machines are known from the textile industry.
- the order the compression needles should have a tangle stitch arrangement are sufficient for the outer surface areas or layers as punctiform as possible and evenly according to the stroke frequency to be set and pre-compressed evenly distributed. It is important to the impact stress caused by the needles one in relation to the surface of the entire mineral fiber web to concentrate small area with it the impact forces compress the described outer zones and due to the force distribution at point loads the layers below it only have low loads Experienced.
- the compaction needles e.g. B. with a short vomadel, the fibers are compressed from the outer Layers in the underlying undensified fiber layers forced so that additional connections arise that the bending and tearing behavior of the finished product continue to influence favorably.
- Compaction needles themselves advantageously exist made of light and abrasion-resistant material. It is The aim is to measure the mass of the needles and the mass to be moved To reduce components as possible, so that correspondingly higher stroke frequencies are possible. This is particularly important at high line speeds in the production of mineral fiber webs.
- the compaction and felting can be carried out either on the top or bottom of the mineral fiber web or, as illustrated in FIG. 5 and in particular FIG. 4 on an enlarged scale, on both sides.
- the mineral fiber web 17 compressed on both sides then has two compressed and matted surface areas 34 and 35 and an intermediate non- compacted and non-matted middle layer 17 and 37, however, a good connection between the layers is ensured.
- a slicing device (not shown) for cutting a mineral fiber web 17 or 21 matted and compacted on both sides can be provided in two partial webs corresponding to the separating cut 36 (FIG. 4) his.
- FIGS. 1 and 5 further illustrate, becomes from the needling or felting machine emerging compacted mineral fiber web 17 over Conveyor rollers 18, 19 or corresponding endless conveyor belts fed to a hardening furnace 20 in which the mineral fiber web 21 between, for example, not shown endless tapes yet another minor Post-compaction can get to especially the Smooth surfaces.
- a hardening furnace 20 in which the mineral fiber web 21 between, for example, not shown endless tapes yet another minor Post-compaction can get to especially the Smooth surfaces.
- the mineral fiber web occurs in the direction of the arrow 23 out of the hardening furnace and can be placed in suitable plate pieces separated and processed into the end product or the described cut 36 effect the separation into plate parts according to FIG.
- Figures 1 and 5 show yet another embodiment the device according to the invention, namely that one-sided ( Figure 1) or both-sided ( Figure 5) between the plate-like needle carriers 11 and 12 on the one hand and the mineral fiber web 10, 17 on the other hand, respectively another plate 24 and 25 is provided in which the needles 13, 14 are guided.
- These plates 24 and 25 can also be connected to the lifting device his. You can add some extra Effect surface compaction, but above all can these plates are used, possibly from the surface ripped fibers back into the surface to press.
- the lifting devices arranged on both sides according to FIG. 5 are advantageously in the direction of Arrows 15 and 16 with the same stroke frequency and in push-pull operated, d. H. if the upper lifting device moved down, the under lifting device moved up at the same time and vice versa at Backbeat. Since the device according to FIG. 5 is horizontal Center plane essentially symmetrical or is designed in mirror image, are for the same or parts with the same effect use the same reference numerals been.
- a further embodiment of the invention is thereby achieved that the needles formed as hollow needles and to an additive feeder, preferably liquid additives.
- an additive feeder preferably liquid additives.
- the needles for Adaptation to the conveying speed of the mineral fiber web during the puncture in cycles Movable conveying direction, preferably swiveling are mounted on the lifting device. In this way the needles are spared, friction and the associated Avoiding warming and a risk of breaking off practically completely excluded.
