Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Spinnmaschinenstreckwerk mit Verdichtungsvorrichtungen, die Verdichtungsriemchen mit einer oder mehreren linienförmigen Perforationsspuren aufweisen, die insbesondere eine Ausgangswalze des Streckwerkes und breite Saugöffnungen aufweisende Saugschuhe umschlingen, welche dem Verzugsbereich des Streckwerks nachgeordnet sind.The The invention relates to a spinning machine drafting system with compacting devices, the compaction straps with one or more linear Have perforation, in particular an output roller the drafting and wide suction suction cups wrap around, which downstream of the drafting area of the drafting system are.
Stand der TechnikState of the art
Neben
Streckwerken allein zum Verfeinern von Faserlunten und Abliefern
der verfeinerten Faserlunten sind Streckwerke bekannt (
Für dieses Verdichtungsspinnen sind unterschiedliche Einrichtungen vorgeschlagen worden. Die vorliegende Erfindung geht von pneumatischen Verdichtungsaggregaten aus, bei denen die Faserverbände durch Ansaugen an eine sich entlang des Faserverlaufs erstreckende Perforationsspur zusammengefasst werden, durch die mittels Saugzugs Luft eingesaugt wird. Diese Perforationsspuren sind in eine Lieferwalze des Streckwerkes und eine Saugöffnung aufweisende Saugschuhe umschlingenden, endlosen Riemchen angeordnet.For This compaction spinning different devices are proposed Service. The present invention is based on pneumatic compression units from, in which the fiber composites by suction on a summarized along the fiber path extending perforation track be sucked through the air by means of suction. These perforation traces are in a delivery roller of the drafting system and a suction port comprising suction shoes wrapped around, endless straps arranged.

Bisweilen soll auf die Verdichtungsfunktion des Streckwerkes verzichtet werden. Dies kann ersichtlich nicht einfach durch Abstellen des Besaugens des Verdichtungsaggregates erfolgen, weil dadurch das Führen der Fasern in dem bis dahin als Verdichtungsfeld wirkenden Bereich unter dem perforierten Riemchen nicht mehr gegeben ist. Die Fasern stauen sich vor dem bisherigen Verdichtungsaggregat und führen zum Fadenbruch.from time to time should be dispensed with the compression function of the drafting system. Obviously, this can not be done simply by stopping the blowing the compression unit done, because thereby the leadership the fibers in the area previously acting as a compaction field under the perforated strap is no longer present. The fibers jam yourself before the previous compression unit and lead for thread breakage.

Allgemeine Beschreibung der ErfindungGeneral description of the invention
Der Erfindung war daher die Aufgabe gestellt, das Unterbinden der Funktion des Verdichtens auf einfachere Weise zu erreichen. Sie löst diese Aufgabe durch die im Hauptanspruch genannten Merkmale.Of the Invention was therefore the task of preventing the function of compacting in an easier way to achieve. She dissolves this object by the features mentioned in the main claim.
Durch das Austauschen der die Perforationsspur enthaltenden Riemchen durch Siebriemchen erfolgt kein seitliches Zusammenfassen und damit Verdichten der Faserverbände mehr. Durch den aufrecht erhaltenen Saugzug durch die Siebriemchen und die Saugschuhe werden die verfeinerten Faserverbände jedoch nach wie vor vom letzten Streckwalzenpaar des Streckwerks unter die Saugriemchen und in das Ausgangswalzenpaar gezogen, ohne sich zu stauen.By replacing the straps containing the perforation track Siebriemchen takes place no lateral summarization and thus compaction fiber composites more. Through the maintained suction train through the sieve straps and the suction shoes are the refined However, fiber composites still from the last drafting roller pair of Drafting under the suction cups and in the output roller pair pulled without jamming.
Bevorzugt wird die Erfindung an Verdichtungsvorrichtungen eingesetzt, bei denen die Verdichtungsriemchen die Ausgangsoberwalze des Streckwerks umschlingen. In diesem Falle ist der Austausch der Riemchen an den fliegend gelagerten Walzen der Oberwalzenzwillinge besonders einfach. Dies insbesondere auch dann wenn sich auch die Saugschuhe nur über den Bereich jeweils eines Oberwalzenzwillings erstrecken.Prefers the invention is used in compression devices, in the compression straps are the topmost roller of the drafting system entwine. In this case, the replacement of the straps to the flying superimposed rolls of Oberwalzenzwillinge particularly simple. This especially even if the suction shoes only over extend the range of each one Oberwalzenzwillings.
Der Einsatz der Erfindung ist jedoch nicht auf diese Ausführungsform beschränkt, sie kann auch an Unterwalzen umschlingenden Verdichtungsriemchen eingesetzt werden.Of the However, use of the invention is not based on this embodiment limited, it can also be entwined on bottom rollers Verdichtungsriemchen be used.
