Description
Es ist :bekannt, Formkörper aus gegebenenfalls mit härtbaren Bindemitteln imprägnierten und vorzugsweise unter Erhaltung eines porösen. Gefüges verfestigten Faserstoffen herzustellen. Anf solche Weise kann man, aus Aufschwemmungen von vorzugsweise verfilzbarem Faserstoffen, wieHolzschliff, Defibnatorstoff, Stroh,AgbestundähnlichenStoffen, zweckmäßigunter MitverwendungvonPhenoplasten, Aminoplasten oder anderen thermisch härtbaren Bindemitteln sowie Zusätzen, wie Füllstoffen, Farben usw., zu Faserstoff-Formkörpern verschiedens.ter spezifischer Gewichte, wie: Kunstkork, Kunstholz undanderen kunststoffähnlichen Erzeugnissen, gelangen. Derartige Formkörper wenden allgemein in Form von Platten hergestellt und sind als Faserstoffplatten, Bauplatten, Isolierplatten und Kunstholzplattenbekannt.It is known: molded bodies made of binders which may optionally be curable with curable binders impregnated and preferably maintaining a porous. Solidified structure Manufacture fibrous materials. In such a way one can, from suspensions of preferably feltable fibers such as wood pulp, defibnator material, straw, agbest and similar materials, expediently with the use of phenoplasts, aminoplasts or others thermally curable binders and additives, such as fillers, paints, etc., to form fibrous molded articles various specific weights, such as: synthetic cork, synthetic wood and other plastic-like Products. Such moldings generally turn in the form of plates and are known as pulp panels, building panels, insulating panels, and synthetic wood panels.
DieErfindung;betrifftFormkörper aus gegebenenfalls mit härtbaren Bindemitteln imprägnierten und vorzugsweise unter Erhaltung eines porösen Gefüges verfestigten Faserstoffen, welche sich von den vorerwähnten Platten !dadurch unterscheiden, daß sie eine Profilform aufweisen, :die dadurch gewonnen worden ist, sdaß zunächst Platten geformt werden, die sich aus einer oder mehreren Profilformen zusammensetzen bzw. regelmäßig uneben sind, und diese an sich fertigen, verfestigten bzw. ausgehärteten Plattere dann nachträglich längs und bzw. oder quer in idie einzelnen Profilstücke aufgeteilt werden.The invention relates to molded articles made from binders which may optionally be curable impregnated and preferably solidified while maintaining a porous structure Fibers which differ from the plates mentioned above in that they have a profile shape, which is obtained by first of all plates which are composed of one or more profile shapes or are regularly uneven, and these manufactured, solidified or hardened Then later cut lengthways and / or crossways into the individual profile pieces be divided.
Auf solche Weisse lassen sich z. B. gewellte, halbröhrenförmige, winklige, wul tige oder sonstige Profilstücke erhalten, welche vielfacher Verwendung und Weiterverarbeitung fähig sind. Die erfindungsgemäßen Formkörper sind zahl reichen Anwendungsgebieten zugänglich,, welche ,den bekannten, nur in Form von Platten vorliegenden Formkörpern versagt bleiben.In such a white z. B. corrugated, semi-tubular, angular, Wul term or other profile pieces received, which multiple uses and further processing are capable. The moldings according to the invention are numerous areas of application accessible ,, which, the known, only present in the form of plates moldings fail.
Erfindungsgemäß werden zunächst plane Platten hergestellt, z. B. gegossen, und diese vorgeformten planen Platten dann in noch verformbarem Zustand zu sich aus einer oder mehreren Profilformen zusammensetzenden Platten nachgeformt, z. B. in noch nassem Zustand zwischen Heizpressen mit Preßformen entsprechenden Querschnittes nachgepreßt und ausgebeizt. Man kann auch derart vorgehen, daß die nassen Faserstoffaufbereitun@gen unmittelbar in Platten"die sich aus einer oder mehreren Profilformen zusammensetzen, übergeführt z. B. in entsprechend gestaltete Formen gegossen und in entsprechend gestalteten Heizpressen getrocknet werden. Wenn die Vemforrnung bereits zu genügend formbeständigen Gebilden geführt hat, kann die Trocknung auch auf rbeliebige Weise durchgeführt werden.According to the invention, planar plates are first produced, for. B. cast, and these preformed planar plates are then in a still deformable state to themselves post-formed from one or more profile shapes composing plates, z. B. in the still wet state between heating presses with press molds of the appropriate cross-section repressed and pickled. One can also proceed in such a way that the wet fiber preparations directly in panels "which are composed of one or more profile shapes, transferred z. B. poured into appropriately designed molds and in accordingly designed heating presses are dried. If the deformity is already too good has resulted in dimensionally stable structures, drying can also be done in any way be performed.
In allen Fällen wenden die an sich fertigen verfestigten bzw. ausgehärteten Platten nachträglich längs und bzw. oder quer in die einzelnen Profilstücke aufgeteilt, z. B. zerschnitten otder zersägt.In all cases, the solidified or hardened ones turn to be finished Panels subsequently divided lengthways and / or across into the individual profile pieces, z. B. cut or sawn up.
In der Zeichnung sind einige Ausführungsformen ;des Erfindungsgegenstandes schematisch dargestellt. Fig. z zeigt eine auf eine sich aus mehreren, Winkelprofilformen zusammensetzende Faserstoffplatte, welche längs geschnitten. ist, so #daß die einzelnen Profilkörper i entstehen.In the drawing are some embodiments of the subject matter of the invention shown schematically. Fig. Z shows one of several, angular profile shapes composing fiber board, which is cut lengthways. is so # that the individual Profile body i arise.
Fi.g. 2 zeigt eine sich aus mehreren Höckerprofilen zusa mnmensetzende Faserstoffplatte, welche: längs und quer geschnitten ist, so:daß idie einzelnen Formkörper 2 entstehen.Fi.g. 2 shows one composed of several hump profiles Fiber board, which: is cut lengthways and crossways so: that i the individual Shaped body 2 arise.
Fig. 3 und 4 zeigen je eine sich, aus. mehreren Wellprofilformen zusammensetzende Ferserstoffplatte, welche in dem in Fig. 3 dargestellten Fall quer und in dem in Fig. 4 dargestellten Fall längs geschnitten ist, so daß die einzelnen Formkörper 3 bzw. 4 entstehen.Fig. 3 and 4 each show one off. composing several corrugated profile shapes Heel material plate, which in the case shown in Fig. 3 transversely and in the in Fig. 4 case shown is cut lengthways, so that the individual moldings 3 or 4 arise.
