Description

.i,#'inrichtuyi,g 1 -zum Formschleif en von Rundteilen aus Holz Die 3rfindung betrifft eine verbesserte Ausbildung einer Einrichtun- zum Formschleifen von Rundteilen aus Holz und z"mjar einer Einrichtung mit einem endlosen Schleifband und einer profilierten Platte auf der Rückseite des Schleifbandes. Durch die unter dem Schleifb'and mit einem gewissen Anpreßdruck hindurchgefiihrten Rundholzstücke wird das Schleifband gegen die profilierte Platte gedrückt, nimmt also hier das herzustellende Profil an, das durch die Schleifwirkung spanabhebend auf die Rundholzstücke übertragen wird. Der Grundaufbau eimer solchen Einrichtung sei an Hand der Zeichnung erläutert. Die Hauptteile der -L#inrichtung sind das endlose Schleifband 1, das über Walzen 2,3 geführt ist, eine Kette 4 mit Aufnehmern 5 für die Rundholzabschnitte 6 und Profilplatten 7 und 8. Ob eine einzige Profilplatte ausreicht, ob, wie im Beispiel, zwei derartige Profilplatten vorgesehen sind, oder ob deren Zahl noch vergrößert werden mußp richtet sich nach dem durchzuführenden 2rofilschleifvorgang, iLi beispie! ist angenommen, ügü es sich um die Herstellung von -f-k* r alerrundpinsel himide.11 , Lz-'sü um k«iroer etwa von -#4isoliba-uch.L'orr#, r,-.it zugespitztt--.#:.-. .#;ntsprechend sind auch die Hatten 7,8 profili#-,#l#tt wie aus Pi,7,ur 2 ersichtlich Lot.

Verhalten des Schleifbandes. -s zeL#t sich nämli,l-:., daß sich das 3--Ind längt und Falten wirft mit dem Ergebnis, duß es nicht mehr satt an der 2rofilplatte anliegt. Dann ist aber eine saubere Pormgebung des zu schleifenden Körpers nicht mehr möglich. Mit der t5eseitigung derartiger störender -z,-r.,jcheinungen beschäftigt sich die ---,rfindung. Sie löst die sich ergebende Aufgabe dadurcht daß die Andrückplatten mit Ausnehmungen zum Anschluß an Vakuum versehen sind. Zu dem durch die Formstücke hervor-erufenen mechaniachen Anpreßdrucic tritt je-.-zt U n der -i;if uer q#-##ij--en Fl#-:che wirkende Atmo#-,-c.Iju'redru--J#.- klin-zul der ein sa-Aes ues er.

Whether a single profile plate is sufficient, whether , as in the example, two such profile plates are provided, or whether their number can be increased mustp depends on the 2-profile grinding process to be carried out, iLi example! it is assumed that it is about the production of -fk * r alerrundpinsel himide.11 , Lz-'sü um k «iroer from - # 4isoliba-uch.L'orr #, r, -. it pointed -. # : .-. . #; Correspondingly, the hats 7,8 are profili # -, # l # tt as can be seen from Pi, 7, ur 2 Lot.

But then a clean shaping of the body to be ground is no longer possible. The ---, rfindung deals with the removal of such disturbing -z, -r., J-phenomena. It solves the resulting problem in that the pressure plates are provided with recesses for connection to a vacuum.
