Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei der Herstellung von Friesbrettern ist es von Wichtigkeit, dafs die Bearbeitung derselben an den Stirnflächen, in welche nachträglich Nuth und Feder eingearbeitet werden, mit grofser Genauigkeit erfolgt. Dies gilt insbesondere für die Nuthseite, weil diese bei verlegtem Fufsboden zu Tage tritt.In the manufacture of frieze boards it is important that the work is done on them on the end faces, into which grooves and tongues are subsequently incorporated great accuracy. This applies in particular to the nut side, because this is the case when the Floor comes to light.

Die bisher zu diesem Zwecke verwendeten Kreissägen haben aber den Nachtheil, dafs sie keine vollkommen gerade und zur oberen Seitenfläche der Bretter genau senkrechte Schnittfläche erzeugen, so dafs auch kein genaues Ineinanderpassen der Friese im Fufsboden zu erreichen ist.The circular saws hitherto used for this purpose have the disadvantage that they not perfectly straight and exactly perpendicular to the upper side of the boards Create a cut surface so that the friezes in the floor do not fit exactly into one another can be achieved.

Die Einrichtung zur genauen Bearbeitung der Stirnflächen der Friesbretter besteht aus zwei senkrecht über einander und waagrecht gelagerten Fräsköpfen, welche derart dicht zusammenarbeiten bezw. einander so weit genähert sind, dafs ihre wirksamen Schneiden sich nahezu berühren.The device for the precise processing of the end faces of the frieze boards consists of two Milling heads mounted vertically above each other and horizontally, which work so closely together respectively are so close to one another that their effective cutting edges almost touch one another.

In der Zeichnnng ist ein Paar solcher Fräsköpfe in der Vorderansicht (Fig. ι) und in der Seitenansicht (Fig. 2) dargestellt.In the drawing is a pair of such milling heads in the front view (Fig. Ι) and in the Side view (Fig. 2) shown.

Jeder Fräskopf α α ist mit je zwei Paaren von stellbaren Werkzeugen b b bezw. c c versehen, von denen erstere die Vorarbeit, letztere die Vollendungsarbeit bewirken.Each milling head α α is with two pairs of adjustable tools bb respectively. cc , of which the former do the preparatory work, the latter do the finishing work.

Die Werkzeuge b sind gezahnte Fräsmesser, welche einander so weit genähert sind, dafs sie an einander ungehindert vorbeigehen können. Sie nehmen das Holz bis auf einen schmalen, ihrem Abstande entsprechenden Grat weg. Dieser letztere wird durch die Schneidstähle c c weggeschnitten, welche hinter den Werkzeugen g in den Fräsköpfen eingespannt und in senkrechter Richtung so weit genähert sind, dafs ihre Schneiden cl c1 dicht an einander vorbeigehen bezw. sich nahezu berühren. Sie nehmen daher den Grat glatt weg und erzeugen eine ebene, zur Längsrichtung der Friese senkrechte Schnittfläche.The tools b are toothed milling cutters, which are so close to one another that they can pass one another unhindered. They take the wood away except for a narrow ridge that corresponds to their distance. This latter is cut away by the cutting steels cc , which are clamped behind the tools g in the milling heads and are approached in the vertical direction so far that their cutting edges c l c 1 pass each other closely. almost touching each other. They therefore remove the burr smoothly and create a flat cut surface perpendicular to the longitudinal direction of the frieze.
