Holzzerfaserungs-Maschine.Wood shredding machine.
Patentirt im Deutschen Reiche vom 26. März 1882 ab.Patented in the German Empire on March 26, 1882.
Diese Neuerung soll dazu dienen, die zur Fabrikation von Holzstoff bestimmten Holzklötze, nachdem solche von der Rinde befreit sind, zu zerfasern.This innovation is intended to make the wooden blocks intended for the manufacture of wood pulp, after these have been freed from the bark, to be shredded.
Zu diesem Zwecke sind innerhalb der Horizontalscheibe A vor den Messern α konische Schneidewalzen S angebracht, welch letztere aus dünnen Stahlblechscheiben hergestellt sind und mit ihren geschärften Aufsenkanten in gleicher Höhe wie die Messer α über die Horizontalscheibe hervortreten.For this purpose, conical cutting rollers S are mounted in front of the knives α within the horizontal disk A , the latter made of thin sheet steel disks and with their sharpened outer edges protrude at the same height as the knife α over the horizontal disk.
Oberhalb der Horizontalscheibe ist ein rahmenförmiger und in mehrere Abtheilungen getheilter Kasten K auf das Gestell g aufgesetzt. Above the horizontal disk, a frame-shaped box K, divided into several compartments, is placed on the frame g .
Das Zerfasern der Holzklötze H erfolgt, indem letztere in den rahmenförmigen Kasten K eingelegt und mittelst Gewichte belastet werden, wodurch dieselben mit gewissem Drucke auf der Horizontalscheibe A aufliegen.The fraying of the wooden blocks H takes place in that the latter are placed in the frame-shaped box K and loaded by means of weights, as a result of which they rest on the horizontal disk A with a certain amount of pressure.
Durch Umdrehung der letzteren (in der Pfeilrichtung) greifen nun zuerst die konischen Schneidewalzen »S etwas in das Holz ein, und die so gebildeten Fasern werden sodann durch die Messer a in entgegengesetzter Schnittrichtung weggeschnitten, was sich so lange wiederholt, bis der Holzklotz vollständig zerfasert ist.By turning the latter (in the direction of the arrow), the conical cutting rollers S engage a little in the wood, and the fibers formed in this way are then cut away by the knives a in the opposite cutting direction, which is repeated until the block of wood is completely frayed is.
