Abstract
Description
Die Erfindung betrifft einen Saugkanal für eine einem Streckwerk einer Textilmaschine nachgeordnete Faserbündelungseinrichtung mit einem rohrförmigen Grundkörper, dessen Außenkontur eine Gleitfläche für ein luftdurchlässiges Transportband enthält, und mit wenigstens drei Saugschlitzen, wobei drei Saugschlitze einem Streckwerk zuordenbar sind und durch jeden Saugschlitz einer von drei getrennt in dem Streckwerk verzogenen Faserverbänden aus Stapelfasern verdichtbar ist.The The invention relates to a suction channel for a drafting system a textile machine downstream fiber bundling device with a tubular base body whose outer contour a sliding surface for an air-permeable Contains conveyor belt, and with at least three suction slots, wherein three suction slots are assigned to a drafting and by each suction slot one of three warped separately in the drafting system Fiber composites of staple fibers is compressible.

Der Erfindung liegt die Aufgabe zu Grunde, einen Saugkanal der eingangs genannten Art zu schaffen, bei dem die Verdichtungswirkung verbessert ist.Of the Invention is based on the object, a suction channel of the above to create said type, in which the compression effect improves is.
Die Aufgabe wird dadurch gelöst, dass jeder Saugschlitz wenigstens einen Bereich mit einer geneigt zur Umfangsrichtung des Grundkörpers verlaufenden Faserleitkante aufweist.The Task is solved in that each suction slot at least an area inclined to the circumferential direction of the main body having extending fiber guide edge.
Durch eine geneigt zur Umfangsrichtung des Grundkörpers verlaufende Faserleitkante wird der auf dem Transportband über den Saugschlitz transportierte Faserverband leicht eingerollt, so dass sich abstehende Faserenden besser an den Faserverband anlegen und der verdichtete Faserverband eine geringere Haarigkeit aufweist. Es ist vorteilhaft, dass die Faserverbände nach Durchlaufen der Verdichtungszone geringere Abstände zueinander aufweisen, damit die Eindrehung in einen gemeinsamen Faden möglichst fehlerfrei vonstatten geht. Dies kann bevorzugt dadurch erreicht werden, dass die Faserleitkanten der beiden äußeren Saugschlitze, entgegengesetzt zueinander geneigt sind.By an inclined to the circumferential direction of the body extending Faserleitkante is the on the conveyor belt on the Suction slot transported fiber composite slightly rolled, so that create protruding fiber ends better to the fiber structure and the compressed fiber structure has a lower hairiness. It is advantageous that the fiber composites after passing through the compression zone have smaller distances from each other, thus the turning into a common thread as possible error-free. This can preferably be achieved be that the fiber guide edges of the two outer Suction slots, opposite to each other inclined.
Der mittlere Saugschlitz mit einer geneigt zur Umfangsrichtung des Grundkörpers verlaufenden Faserleitkante wird bevorzugt so gestaltet, dass der mittlere Saugschlitz wenigstens zwei Bereiche enthält, in denen die Faserleitkanten einen unterschiedlichen Neigungswinkel bezogen auf die Umfangsrichtung des Grundkörpers aufweisen. Die Faserleitkanten der beiden Bereiche des mittleren Saugschlitzes sind vorteilhafterweise entgegengesetzt geneigt. Eine Faserleitkante kann auch einen gekrümmten Bereich aufweisen oder aus Geradenstücken bestehen. Die Platzverhältnisse zwischen den beiden äußeren Saugschlitzen können so optimal ausgenutzt werden. Es wird erreicht, dass alle drei Faserverbände an einer geneigten Faserleitkante verdichtet werden. Gleichzeitig wird erreicht, dass die drei Faserverbände während des Verdichtungsvorganges stets voneinander getrennt sind und sich nicht gegenseitig berühren.Of the middle suction slot with an inclined to the circumferential direction of the body extending fiber guide edge is preferably designed so that the middle Suction slot contains at least two areas in which the fiber guide edges related to a different inclination angle have on the circumferential direction of the body. The Faserleitkanten the two areas of the central suction slot are advantageously inclined in opposite directions. A fiber guiding edge may also have a curved area or straight line pieces consist. The space between the two outer Suction slots can be optimally utilized. It will achieved that all three fiber composites at an inclined Faserleitkante be compacted. At the same time it is achieved that the three fiber composites during the compaction process are always separated from each other and do not touch each other.
