    STRENGTH MOND. STRENGTH DEVICE AND METHOD FOR MANUFACTURING STONE STRIPPES
    This invention relates to an extruder mouth comprising an elongated opening for pressing through clay or the like for the manufacture of brick slips.
    In addition, this invention relates to a cord press device for manufacturing brick slips, comprising such a cord press mouth.
    This invention further relates to a method for manufacturing brick slips, comprising pressing clay or the like through such an extruder mouth.
    Brick slips are mainly used for renovations, where external insulation is applied, and the façade is then finished with brick slips, to give this façade the appearance of a traditional brick façade.
    Such brick slips are until now usually manufactured by sawing thin strips of brick along one or both sides of bricks. Thin strips of two sides connecting at an angle with respect to each other are thus also sawn off to produce a corner brick strip.
    The manufacture of brick slips in this way has a number of disadvantages and is also very laborious and expensive. In the first place, the brick slips must be made from already baked brick.
    After all, the bricks from which the brick slips are sawn are first packaged and then taken to the sawmill, where they are manually applied to the sawing machine. These bricks are then sawn into brick slips and the resulting brick slips are packaged back.
    Sawing brick slips from bricks also requires a lot of energy.
    When sawing brick slips from bricks, there is usually also about 15% failure due to incorrect sawing or breaking the strip when sawing.
    The part of such bricks from which the brick strip is sawn off is lost, or its recovery (ground into brick rubble) is laborious and energy-consuming.
    Only one single brick strip can usually be obtained from one brick, as a result of which the majority of the material of such a brick is lost. In addition, the energy used for drying and baking this part of material that is lost is also lost.
    In FR 3 007 683 a method is described for nevertheless being able to extract two brick slips from a single brick, of which initially only one side was suitable as a visible side, this by a brick strip cut off on the opposite side from the visible side of a brick, an additional to give treatment to make it suitable as a visible side.
    It is also known to manufacture special hollow bricks from which brick slips can be sawn, whereby due to the presence of the cavities less material is lost when sawing a brick sliver from such a hollow brick than when sawing brick slips from solid bricks.
    In GB 2 485 540 A it is described how also hand-molded bricks and molded bricks with a certain cavity can be manufactured in order to be able to saw stone strips therefrom with less loss of material.
    From WO 2013/186566 A1, for a specific composition of brick material, it is known to already cut a brick formed therefrom to extract a brick strip therefrom before baking, so that the energy for baking the lost part of material no longer is lost.
    In EP 2 826 608 A1 an alternative manufacturing method is described for the direct manufacture of brick slips in a press, wherein the brick material is cut to size with the aid of a pressing device. However, this method is only suitable for bricks that are not very plastic in the unfired state. Although the appearance of a hand-molded brick is contemplated here, a brick strip with such a method comprises more flat walls than with brick strips made from hand-molded bricks, so that the same aesthetic effect can never be obtained with this.
    The direct manufacture of brick brick slips is not done in practice, since, on the one hand, due to the limited thickness of brick slips, it is not possible to manufacture hand brick slips directly in molds and, on the other hand, it means too large an investment for the proportion to be produced for extruded brick brick slips compared to the proportion of bricks to be manufactured. Stone strips that would be produced directly through an adapted opening in an extruder mouth, without excess material, do not only require an adapted extruder, but also require an adapted treatment in the further production process, in view of the dimensions of an extruded strand and the resultant extruded material. cut sections of length that form the brick slips after drying and baking, have different dimensions from the bricks normally produced with such installations.
    The object of this invention is to provide a solution to the above-mentioned problems, so that it becomes possible to manufacture brick slips in an economically feasible manner, with less energy and without great loss of material or high laborability for recovering material.
    This object of the invention is achieved in the first place by providing an extruder mouth comprising a plurality of elongated openings for pressing through clay or the like for the manufacture of brick slips, said elongated openings being arranged parallel to each other.
    When in an existing extruder press manufacturing plant, the extruder mouth is replaced by an extruder mouth of this invention, then strands pressed through such an extruder mouth can be further treated together with the existing plant as a brick. Partial strands from strands that are pressed through such an extruder mouth and which are sawn together to length, should herein together have substantially similar dimensions to corresponding bricks.
    Stone strips can then be formed from these sub-strands per se by drying and baking, without having to be sawn further after being cut to length. In this way, less energy is needed to manufacture such brick slips and these brick slips are produced virtually without loss of material.
    With existing business infrastructure, brick slips can therefore be manufactured only by replacing the extruder mouth. Furthermore, the strands thus pressed can be sawn together with the sawing installation present, dried together in the same drying process, baked together in the same baking process and traded together in between.
    Stone strips can thus also be manufactured from the same batch of clay as, for example, solid stones or stones with other sizes. This offers a major advantage in the case of renovations, whereby stones of different sizes with the same appearance are desired, on the one hand to erect new walls and on the other to cover existing walls.
    Said rectangular openings will typically be substantially rectangular in shape, but can of course also be provided with the necessary notches or toothings to emboss the stone strips during pressing through the extruder mouth, in order to provide a structure on it, to make the stone strips of provide feet or anchoring elements, etc.
    The said elongated openings preferably have substantially the same dimensions, so that brick strips with substantially the same dimensions can be produced with them.
    A particularly preferred embodiment of an extruder mouth according to the present invention comprises, in addition to the said elongated openings, also a substantially L-shaped opening. The L-shape of this opening comprises a longer leg and a shorter leg, the longer leg being arranged parallel to said elongated openings and the shorter leg extending alongside at least a part of said elongated openings. These legs are preferably substantially perpendicular to each other.
    The extruder mouth is preferably received in an extruder such that the L-shaped opening with its longer leg is arranged above various said elongated openings. In this way it becomes possible to produce corner stone strips together with elongated brick slips, because the strand which is pressed through the L-shaped opening and sub strands sawn from it to lengths are always supported by the strands or sub strands pressed below.
    The longer leg of such an L-shaped opening preferably has substantially the same dimensions as the elongated openings.
    The length of the shorter leg is preferably substantially the same length as the sum of the widths of the elongated openings. The L-shaped opening is then preferably included in the extruder mouth as the upper of said openings, so that a strand pressed through it will be maximally supported by the strands pressed through the elongated openings and so that sub strands sawn to length from these strands together assume dimensions which correspond as closely as possible to a corresponding brick that can be manufactured with a different extruder mouth with a business infrastructure corresponding to the rest.
    The object of this invention is also achieved by providing an extruder device for manufacturing brick slips, comprising an extruder mouth, the extruder mouth being an extruder mouth described above according to the present invention.
    Such an extruder device according to the present invention preferably comprises diverging means for separating strands which are pressed through two adjacent elongated openings.
    With such diverging means it becomes possible, after pressing the strands and before cutting them to length, to treat the adjacent surfaces to give them, for example, a different color or a different surface structure. For example, these surfaces can be sprinkled with sand or sprayed with dyes or embossed with relief rolls, etc.
    Such an extruder device preferably comprises diverging means corresponding to each of two adjacent openings.
    More specifically, an extruder with diverging means may comprise a roller device as said diverter means for bringing apart the strands pressed through said two adjacent elongate openings.
    The object of this invention is furthermore also achieved by providing a method for manufacturing brick slips, comprising pressing clay or the like through an extruder mouth, wherein clay or the like is pressed through an extruder mouth according to the invention described above.
    Such a method preferably further comprises joining the strands pressed through the extruder nozzle.
    More specifically, such a method may further comprise cutting the bundled strands together into sub strands.
    Furthermore, such a method can also comprise drying the sub-strands thus cut together.
    In addition, such a method may also comprise baking the sub-strands thus cut together after drying.
    In a method for manufacturing brick slips according to the present invention, the brick slips are preferably manufactured with the aid of a previously described extruder device according to the present invention which comprises diverging means. Two strands that are pressed through said two adjacent elongated openings of the extruder are then first disassembled by means of the diverging means, before these strands are brought back together. In this way it is more easily possible to treat the respective surfaces of the strands by giving them a relief and / or color, etc.
    A method according to the present invention further preferably also comprises treating surfaces of the strands pressed through the extruder nozzle. Possible treatments are sanding, spraying with dyes, applying relief, for example with the help of a roller, etc.
    Preferably, in such a method according to this invention, the facing surfaces are treated of strands disassembled according to a method described above, before these strands are brought together.
    This invention will now be further elucidated on the basis of the following detailed description of a preferred extruder mouth, a preferred extruder device and a preferred method for manufacturing brick slips according to the present invention. The purpose of this description is to provide illustrative examples only and to indicate further advantages and details of this invention, and thus cannot be interpreted as limiting the scope of the invention or the patent rights claimed in the claims.
    In this detailed description reference is made by reference numerals to the accompanying drawings, in which - in Figure 1, a cord press according to the invention is schematically shown in view.
    The extruder nozzle (1) shown in Figure 1 comprises four elongated rectangular openings (2) arranged parallel to each other. An L-shaped opening (3) in this extruder mouth (1) is arranged with its longer leg (4) above and parallel to these rectangular openings (2), and with its shorter leg (5) next to a part of these rectangular openings ( 2) prepared. The elongated openings (2) and the L-shaped opening (3) are each made equally wide, with the same width (B). The elongated openings (2) and the longer leg (4) of the L-shaped opening are each of the same length, with the same length (L). The shorter leg (5) has a length (1) corresponding to the sum of the widths (B) of the elongated openings.
    In this way, a strand which is pressed through the L-shaped opening (3) of the extruder mouth (1) will be supported maximally by strands that are simultaneously pressed through the elongated openings (2).
    These strands can then be brought together into a whole that can be further treated together during the further production of the brick slips. The compressed strands can thus be cut to length together with the aid of a cutting device. The sub-strands thus formed can then be dried together and finally baked together to form brick slips. In between, these sub-strands can also be traded together in each case.
    If it is desired to give the strands a treatment in order to give the brick slips made on the basis thereof, for example, a different color or relief, etc., an extruder with an illustrated extruder mouth (1) can furthermore preferably be provided per two adjacent openings (2). 3) diverging means to disassemble the strands. These diverging means can for instance be roller devices. When the strands have been brought apart with the aid of such diverging means, it is easier to sand their surfaces, or to spray them with dyes, or with the aid of rollers provided with relief, etc. The strands can then be brought back together to make them as already mentioned above. to cut to length, dry and bake into brick slips.
    The openings in the extruded nozzle shown have straight sides. In practice, it is of course also possible to provide these sides with, for example, notches or teeth to emboss the stone strips during pressing through the extruder mouth, to provide a structure on it, to provide the stone strips with feet or anchoring elements. , etc.
