The subject of the invention is a

Device for storing fibrous materials in building material, for example in panels

. Plaster of paris, magnesia cement and other plastic materials used in the manufacture of building materials Fabrics by means of which it is possible to convert these elastic fibers into very quickly setting material without impairing the setting process or durability

ίο the one made from the plastic mass To store building materials permanently.

An example embodiment of the device is shown in the accompanying drawing in Fig. 1 in the top view, in Fig. 2 in section along the plane AB of Fig. 1, while Fig. 3 illustrates an application of the device in connection with a mold frame .

When storing fiber material, for example horse hair, seaweed, coconut fibers, Hemp, jute and the like, the drawback shows that this material is when introduced into the plastic mass of the building material, for example into the freshly mixed plaster of paris, partly as a result of its elasticity, which is increased by the moisture, partly as a result of the setting the plastic mass shifts in such a way that it becomes extremely difficult to distribute nodes form and the fiber material especially withdraws from the edges. But it is important when storing, to distribute the fiber material on the edges and, if possible, something over the Let the edges protrude. It was therefore necessary to date the fiber material in the To distribute the plastic mass by hand, which is a major problem in this respect offered when this plastic material sets in the meantime and it very often, for example When using plaster of paris, it is still impossible to distribute the fibers before setting so quickly that the setting process is unhindered in front of you can walk and no inequalities are formed in the object. It'll come in addition, there is a considerable loss of material in this difficult distribution with the hands arises.

With similar already known devices in which by means of confused Rust causes the introduction of paint into building materials, it would im present case also fail to achieve the desired distribution because here the loose fibers are squeezed out and torn out and such rusts also become fill with the plastic building material and with fibers and the wires or rods when the plastic is set Bend building material easily.

With the device according to the invention *, the desired distribution is now achieved without impairment the setting process by one provided with press jaws or press rods or to achieve the necessary pressure, a screen device with a correspondingly difficult design is achieved, which, if desired, before placing in the mold or in it itself

with a part of the plastic mass mixed or mixed with fiber material is pressed on. This enables new amounts of plastic material to be replenished while the pressure is being exerted, without the fiber material being able to shift or spring back or otherwise change its position. In the embodiment shown in the drawing, a is at α

ίο such a sieve device shown. This one is here with the. longitudinal pressure strips b and the interposed, possibly also used for pressing and then appropriately increased stiffening webs c and for easier handling provided with a handle η and can be applied to the plastic material containing the fiber material in the form d, for example by rotating it Edge, to be placed on and lifted from it.

One can also proceed in such a way that one brings some of the plastic mass into the mold frame d , then inserts or pours in the fibrous materials and spreads the fibers in the plastic mass by repeatedly moving them up and down or pushing them and thereby at the same time a uniform distribution. divisionj_des_p_lastischen ~ Mlitefiärs as well as the

/ F ¥ sjrn_Jb_eför.der £ unä "~ in this way too ^ supports the setting process. The pressing device presses the fibers down against their elasticity and holds them permanently in the plastic mass. Then you can Pour new plastic mass through the sieve, whereupon the device, as soon as the The setting process has progressed sufficiently, is removed.

In the exemplary embodiment shown, the screening device α hangs by means of the hinges g, g ¹ rotatably connected at f on the folding table h, k, k shown here, for example, and can, after the fibers have been stored and tied, in the direction of the arrow in FIG. 3 swung back and possibly held in place by a tooth i of a pedal lever m '.

The device can of course also be used to store other substances, such as wire, glass threads, sheet metal strips or the like, in building material. It is expediently hinged to the supports h of the collapsible molding table k so as not to hinder the actuation of the latter, but can of course also be hinged to the molding table k itself in a different mode of operation and can also be moved in a different manner.
