   Diese Erfindung betrifft ein Verfahren zur Herstellung eines Formkörpers aus miteinander verbundenen Holzschichten. Es unterscheidet sich von den bekannten Arten der Schichtverleimung (Verlelmung mehrerer Holztelle).   Durch diese Herstellungswelse Ist   es   möglich.   Holzspiralen jeder Form herzustellen. Ebenso betrifft diese Erfindung eine Vorrichtung zur Durchführung dieses Verfahrens. 



   Weitere Merkmale und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung sowie an Hand der Zeichnung ; diese zeigen in Fig. 1 eine Ansicht der Holzspirale, in Fig. 2 eine Ansicht der Schablone, in Fig. 3 das Verfahren zur Herstellung einer Heizspirale. 



   Um die Holzspirale   (Fig. 1) herzustellen,   verwendet man Holzstreifen (Fig. 3, A), deren Dicke. Breite, Anzahl und andere Faktoren die Form bestimmen. Diese Holzstreifen (Fig. 3, A) werden mit zum Verleimen von Holz   geeigneten Matenal   beschichtet und anschliessend übereinandergelegt. Diese   überein-   andergelegten Holzstreifen (Fig. 3, A) werden über eine je nach Form gefertigte Schablone (Fig. 2 und Fig.   3.   B) gedreht. Das man nun auch den notwendigen Druck auf die Holzstreifen (Fig. 3, A) ausüben kann. wird mittels eines Spanngurtes oder Ledememens   (Fig. 3, C)   oder anderes, weiches mit einer Schraube   (Fig. 3, D) befestigt ist,   fest und mit viel Druck gegen die Schablone (Fig. 3, B) gedreht. 



   Nach Ende der Presszelt. welche sich nach Art des Klebers, Raumtemperatur und anderes richtet, kann 
 EMI1.1 
 und dieser Art der Schablone (Fig. 2) erfolgt das Trennen durch Drehen von Holzspirale (Fig. 1) und Schablone (Fig. 2) In entgegengesetzter Richtung.

   This invention relates to a method for producing a shaped body from interconnected layers of wood. It differs from the known types of layer gluing (sealing of several wooden parts). Through this catfish it is possible. To produce wooden spirals of any shape. This invention also relates to an apparatus for performing this method.



   Further features and details emerge from the following description and from the drawing; these show in Fig. 1 a view of the wooden spiral, in Fig. 2 a view of the template, in Fig. 3 the method for producing a heating spiral.



   To make the wooden spiral (Fig. 1), one uses wooden strips (Fig. 3, A), their thickness. Width, number and other factors determine the shape. These wooden strips (Fig. 3, A) are coated with material suitable for gluing wood and then placed on top of one another. These superimposed wooden strips (Fig. 3, A) are rotated using a template (Fig. 2 and Fig. 3. B) made according to the shape. That you can now exert the necessary pressure on the wooden strips (Fig. 3, A). is fastened by means of a lashing strap or leather strap (Fig. 3, C) or other, soft with a screw (Fig. 3, D), and with a lot of pressure against the template (Fig. 3, B).



   At the end of the press tent. which depends on the type of adhesive, room temperature and others
 EMI1.1
 and this type of template (Fig. 2) is separated by turning the wooden spiral (Fig. 1) and template (Fig. 2) in the opposite direction.

Claims

1. Process for producing a molded body from layers of wood glued together, thereby EMI1.2 layers lying one above the other are wound helically onto a mold core and pressed onto the mold core until the glue has set.

2. The method according to claim 1, characterized in that the wooden strips are wound together helically on the mandrel.

3. The method according to claim 2, characterized. that the wooden strips by means of a tension-tightly connected to the mold core, placed outside around the wooden strips around the Form core wound and held pressed to this

4. Device for performing the method according to one of claims 1 to 3 with a mandrel, characterized in that the formed with a circular cylindrical or conical shape Mold core (B) In its jacket a helical, open at least on one end Insert groove for the wooden strips (A).
