Description

Selbsttätig ein- und ausnadelnder, schräg ansteigender Aufgabetisch für Fellbearbeitungsmaschinen. Zur Bearbeitung von Fellen sind Aufgabetische bekannt geworden mit einer größeren Anzahl nebeneinanderlaufender, endloser Riemen, die über eine mit Stahlspitzen besetzte Vorschubwalze und eine Gegenwalze gelegt sind. Die Vorschubwalze ist in Ringreihen mit Stahlspitzen besetzt, die Riemen liegen zwischen den Stahlspitzenringreihen.Automatically needling in and out, inclined loading table for skin processing machines. Feed tables are known for processing skins become with a larger number of juxtaposed, endless belts that are placed over a feed roller equipped with steel tips and a counter roller. The feed roller is set in rows of rings with steel tips, the belts lie between the rows of steel tip rings.

Solche Aufgabetische bieten dem zu bearbeitenden Fell keine geschlossene Auflagefläche. Die Auflagefläche ist vielmehr durch die Zwischenräume zwischen denRiemen fortlaufend unterbrochen, und zwar längsspaltartig. Die überhängenden Fellhaare gelangen leicht in die Längsspalten, klemmen .sich dann an der Vorschubwalze ein und werden nicht bearbeitet. Die einzelnen Riemen längen sich leicht ungleichmäßig, laufen dann schief und werden von den Stahlspitzen der Vorschubwalze angestochen. Als Folge entstehen in dem von den Riemen getragenen Fell Falten. Das Fell wird nicht gleichmäßig eingenadelt und beim Vorüberführen an den Schneidwerkzeugen unter Umständen von den Messern zerschnitten.Such feed tables do not offer the skin to be processed a closed one Support surface. Rather, the bearing surface is through the spaces between the belts continuously interrupted, namely in the manner of a longitudinal gap. The overhanging fur hair easily get into the longitudinal gaps, then get caught on the feed roller and are not processed. The individual straps are slightly uneven, then go wrong and are driven by the steel tips of the feed roller pierced. As a result, wrinkles appear in the fur worn by the straps. That Fur is not needled evenly and when passing the cutting tools possibly cut by the knives.

Nach der Erfindung ist der Aufgabetisch durch ein endloses Band gebildet, das für den freien Ein- und Austritt der auf der Vorschubwalze angebrachten Stahlspitzen mit schmalen Aussparungen versehen ist. Die Stellung der Stahlspitzen der Vorschubwalze stimmt mit den Abständen der Aussparungen im Band genau überein und ist unveränderlich, weil das endlose Band von der Vorschubwalze zwangläufig in Bewegung gesetzt wird. Gegen Schieflaufen ist das Band durch die beiden Kettenräder der Vorschubwalze geschützt. Das Fell wird faltenfrei eingenadelt und von den Messern in seiner ganzen Ausdehnung gleichmäßig bearbeitet.According to the invention, the feed table is formed by an endless belt, that for the free entry and exit of the steel tips attached to the feed roller is provided with narrow recesses. The position of the steel tips of the feed roller coincides exactly with the spacing of the recesses in the band and cannot be changed, because the endless belt is inevitably set in motion by the feed roller. The belt is protected against skewing by the two chain wheels of the feed roller. The fur is needled in without wrinkles and the entire extent of the knives machined evenly.

Auf der Zeichnung veranschaulicht die Abb. i den Aufgabetisch im Aufriß, die Abb. 2 dessen Draufsicht. Auf dem feststehenden Tisch a wird das zu bearbeitende Fell ausgebreitet, glattgestrichen und von Hand dem aus e i n e m endlosen Band bestehenden Aufgabetisch b zugeführt. Die im Bereiche des Standmessers e befindliche Vorschubwalze c ist mit Stahlspitzen c" besetzt. Durch das endlose Band b wird das Fell der Vorschubwalze c zugeführt, deren Spitzen von unten her in das Leder des Felles eindringen und es unter die Druckwalze d ziehen. Die Bewegung des endlosen Bandes erfolgt zwangläufig durch die Kettenräder h der Vorschubwalze c, indem die Kettenräder in die Lochreihen i des Bandes b eingreifen.In the drawing, Fig. I illustrates the feed table in elevation, and Fig. 2 shows its top view. The skin to be processed is spread out on the fixed table a, smoothed out and fed by hand to the feed table b, which consists of an endless belt. The feed roller c located in the area of the standing knife e is covered with steel points c ". The fur is fed to the feed roller c through the endless belt b, the points of which penetrate the leather of the fur from below and pull it under the pressure roller d. The movement of the endless belt is inevitably carried out by the chain wheels h of the feed roller c, in that the chain wheels engage in the rows of holes i in the belt b.
