Description
Einrichtung an beheizten Preßvorrichtungen zur Herstellung von Holzgegenständen Die Erfindung betrifft eine Einrichtung an Preßformen zur Herstellung von Holzgegenständen, insbesondere Holzhohlkörpern, bei der die Abführung des bei der Trocknung des geformten Gegenstandes entstehenden Dampfes mittels gelochter Beilagen erfolgt. Diese Beilagen bestanden meist aus gelochtem Blech, dessen Löcher durch Abzugkanäle miteinander verbunden waren. Allein der beabsichtigte Zweck einer beschleunigten Trocknung wurde dabei nur unvollkommen erreicht. Ein Nachtrocknen in besonderen Formen gab zum Verziehen der Hohlkörper Anlaß. Eine unbedingt sichere Einhaltung der gewünschten Form des @Terkstückes ist nur dann--ge=-währleistet, wenn es in der Preßform vollkommen getrocknet wird, was gemäß der Erfindung in kurzer Zeit dadurch erreicht wird, daß als Beilagen Drahtgeflechte Verwendung finden. Dadurch wird ein ungehinderter schneller Durchgang der bei der Trocknung entstehenden Wasserdämpfe erzielt, was eine vollständige Trocknung in mir wenigen Sekunden ermöglicht. Es ist somit ein Weg gefunden zur Herstellung von Massenartikeln aus Sperrholz, die eine Nachbehandlung nicht mehr erfordern, wodurch eine wesentliche Verbilligung erzielt ist. Wird nur eine ortsbeschränkte Trocknung gewünscht, -so ist ohne weiteres durch richtige Anordnung des Gewebes dies zu erzielen. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Die Vorrichtung besteht aus einem Stempel a, der mit Drahtgeflecht c umlegt ist und Dampfabzuglöcher e trägt, sowie aus einer äußeren Form b. Der Arbeitsgang geht wie folgt vor sich: Bei hochgehobenem Stempel a wird in die obere Aussparung der Form b ein vorher in heißem Wasser erweichtes Holzblatt d gelegt, das beim Niederdrücken des Stempels a in die Form b gepreßt wird. Die angewärmten Werkzeuge bewirken ein sofortiges Verdampfen der in dem geformten Hohlkörper d vorhandenen geringen Wassermengen. Die Wasserdämpfe können durch das Drahtgeflecht c und die Löcher e ungehindert abziehen, wodurch ein schnelles Trocknen des Holzes gewährleistet ist.Equipment on heated pressing devices for the production of wooden objects The invention relates to a device on molds for the production of wooden objects, in particular hollow wooden bodies, in which the removal of the formed during the drying The resulting steam takes place by means of perforated inserts. These side dishes consisted mostly of perforated sheet metal, the holes of which were connected to one another by flue channels were connected. The only intended purpose of accelerated drying was only incompletely achieved. Post-drying in special shapes made it warp the hollow body occasion. Absolutely secure compliance with the desired form of the @ Terkstückes is only guaranteed when it is completely dry in the mold is what is achieved according to the invention in a short time that as supplements Find wire meshes use. This makes for an unimpeded quick passage of the water vapors produced during drying, which results in complete drying made possible in a few seconds. A way of production has thus been found of mass-produced articles made of plywood that no longer require post-treatment, whereby a substantial reduction in price is achieved. Will only be a restricted location Drying is desired - this is easily done by correctly arranging the fabric to achieve this. An embodiment of the invention is shown in the drawing. The device consists of a punch a, which is wrapped with wire mesh c and carries steam vent holes e, as well as an outer shape b. The process goes as follows: When the punch a is lifted, the Form b a piece of wood d previously softened in hot water was placed, which when pressed down of the punch a is pressed into the shape b. The heated tools cause a immediate evaporation of the small amounts of water present in the molded hollow body d. The water vapors can escape unhindered through the wire mesh c and the holes e, whereby a quick drying of the wood is guaranteed.
