Description

Entstaubungsvorrichtung für Bastfaserstrecken Gegenstand der Erfindung ist eine Entstaubungsvorrichtung für Bastfaserstrecken, bei denen in einem Kopf mehrere Bänder in Abstand nebeneinanderlaufen und über die ganze Breite der Strecke über dem Nadelfelde ein Saugschlitz angeordnet ist.Dedusting device for bast fiber strands is the subject of the invention is a dedusting device for bast fiber lines, with which in a head several bands run side by side at a distance and across the entire width of the route A suction slot is arranged above the needle field.

Das kennzeichnende Merkmal der Erfindung besteht darin, daß der Schlitz in der Breite stellenweise derart abgedeckt ist, daß er über den Bändern _geschlossen und nur zwischen den. Bändern offen ist. Dadurch wird vermieden, daß bei starkem Luftzug von den Bändern viel wertvolle Fasern mitgerissen werden, weil diese durch die Nadeln gegen den seitlichen Luftzug geschützt sind; gleichzeitig wird dadurch der Übelstand gemildert, daß sich durch mitgerissenes Material der Saugschlitz verstopft.The characteristic feature of the invention is that the slot is covered in places in width in such a way that it _ closed over the ribbons and only between the. Ribbons is open. This avoids that with strong Drafts from the ribbons cause a lot of valuable fibers to be carried away because these are carried through the needles are protected against drafts from the side; at the same time thereby the inconvenience is alleviated that the suction slot is clogged by entrained material.

Die Zeichnung zeigt die Erfindung, und zwar veranschaulicht Abb. i eine Strecke mit der neuen Saugleitung in Vorderansicht.The drawing shows the invention, namely illustrates Fig. I a stretch with the new suction line in front view.

Abb. z ist eine Seitenansicht der Abb. i. Abb. 3 ist eine Draufsicht auf Abb. i, während Abb. q. eine Saugschlitzabdeckung geöffnet schaubildlich zur Darstellung bringt.Fig. Z is a side view of Fig. I. Fig. 3 is a plan view on fig. i, while fig. q. a suction slot cover opened diagrammatically to Representation brings.

An das Saugrohr a ist in bekannter Weise die Saugdüse b angeschlossen, die sich über die ganze Breite des Kopfes erstreckt. Die Bastfaserstrecke besteht in bekannter Weise aus den Rollen c und der Walze d, zwischen denen die Bänder k hindurchgezogen werden. Das Nadelfeld ist mit e, f bezeichnet. Der Schlitz der Saugdüse ist stellenweise durch Abdeckungen g geschlossen, die über den Bändern liegen, so daß der Luftstrom, der durch die Öffnungen h angesaugt wird, nicht mehr senkrecht hochsteigt, sondern nach der Seite gerichtet ist, wie dies die Pfeile i in Abb. i und 3 zeigen.The suction nozzle b, which extends over the entire width of the head, is connected to the suction tube a in a known manner. The bast fiber stretch consists in a known manner of the rollers c and the roller d, between which the tapes k are drawn. The needle field is denoted by e, f. The slot of the suction nozzle is closed in places by covers g, which lie over the belts, so that the air flow that is sucked in through the openings h no longer rises vertically, but is directed to the side, as indicated by the arrows i in Fig. i and 3 show.

In der Praxis wird die Düse vorteilhaft zum Zwecke der leichteren Reinigung so hergestellt, wie es in der Abb. q. zur Darstellung gebracht ist, indem der vordere Rand der aufklappbaren Oberwand i mit Lappen g versehen ist, die senkrecht niedergebogen sind, so daß zwischen ihnen die Öffnungen h verbleiben.In practice, the nozzle is advantageous for the purpose of being lighter Cleaning made as shown in fig. Q. is shown by the front edge of the hinged top wall i is provided with flaps g, which are perpendicular are bent down so that the openings h remain between them.
