Description
Die Erfindung betrifft eine Scherwendel mit einem Klingenteil für einen umlaufenden Scherzylinder, der zum Scheren von Faserflor mit einem Gegenmesser zusammenarbeitet, wobei das Klingenteil im wesentlichen aus einem hochkant gewendelten Band besteht, dessen außen liegende Schmalseite eine Schneide aufweist und wobei an die Schneide eine Brustfläche angrenzt, welche mit dem Gegenmesser schneidend zusammenwirkende Hiebe besitzt.The invention relates to a scissor coil with a blade part for a rotating Shear cylinder that works with a counter knife to shear fibrous web, the blade part consisting essentially of an upright spiral Band exists, the outer narrow side of which has a cutting edge and where a breast surface adjoins the cutting edge, which is with the counter knife has cutting, interacting blows.
Scherspiralen dieser Art werden beschrieben in DE-AS 24 04 837. Im Bekannten werden keilförmige Hiebe beschrieben, deren je zwei Keilflächen an der Schneide der Scherwendel mit der Wendelachse je einen Hiebwinkel einschließen. Es wird angestrebt, ein seitliches Ausweichen der Fasern beim Scherschnitt - etwa wie bei einer Schere mit gezackter Schneidkante - zu verhindern. Um ein Gleiten der Fasern beim Schneiden zu vermeiden bzw höchstens ein dosiertes Gleiten zuzulassen. wird der Hieb der bekannten Scherwendel im wesentlichen so ausgebildet, daß jeweils eine Hiebkante eines keilförmigen Hiebs annähernd wie eine Stanze mit dem Gegenmesser zusammenwirkt. Auf diese Weise läßt sich ein gleichmaßger Faserflor nur erzeugen, wenn die Menge der der jeweiligen Keil- bzw. Hiebschneidkante zugeführten Fasern relativ klein gehalten wird. Die Transportgeschwindigkeiten der zu scherenden Faserflorbahnen, insbesondere bei dichtem Flor, sind entsprechend beschränkt. Erhöht man die Transportgeschwindigkeit bzw. die (relative) Schneidtiefe über eine im Einzelfall zu ermittelnde Grenze, wird ein Teil des zwischen Gegenmesser und Keilschneidkante erfaßten Flors zur Seite gedrängt, so daß sich ungleichmäßige Scherergebnisse einstellen. Der Begriff "Schneidtiefe" bezeichnet die (mittlere) Länge des Florteils, der mit dem einzelnen Schnitt abgetrennt wird. "Relative" Schneidtiefe ist das Verhältnis der abgetrennten Länge zur ursprünglichen (mittleren) Gesamtlänge des Flors.Shear spirals of this type are described in DE-AS 24 04 837. In the known are described wedge-shaped blows, each with two wedge surfaces on the cutting edge the cutting helix with the helix axis each include a cutting angle. It will strived for a lateral dodging of the fibers during shear cutting - as with a pair of scissors with serrated cutting edge - to prevent. To make the fibers slide to avoid when cutting or at most to allow a dosed sliding. the cut of the known scissor coil is essentially designed so that each with a cutting edge of a wedge-shaped cut approximately like a punch interacts with the counter knife. In this way, a uniform Only produce fiber pile when the amount of the respective wedge or chop cutting edge fed fibers is kept relatively small. The transport speeds the fiber card webs to be sheared, especially in the case of dense pile, are corresponding limited. If you increase the transport speed or the (relative) Cutting depth over a limit to be determined in individual cases becomes part of the between Counter knife and wedge cutting edge gripped flores pushed aside, see above that there are uneven shear results. The term "cutting depth" denotes the (average) length of the pile part that is cut off with the single cut becomes. "Relative" cutting depth is the ratio of the length cut to the original (mean) total length of the pile.
Der Erfindung liegt die Aufgabe zugrunde, die Schneide der Scherwendel so auszubilden, daß die Transportgeschwindigkeit der zu scherenden Stoffbahn und/oder die Schneidtiefe, auch bei dichtem Flor, gegenüber dem Stand der Technik wesentlich erhöht werden kann und trotzdem ein gleichmäßig geschorener Faserflor erhalten wird.The invention has for its object to form the cutting edge of the shear helix so that the transport speed of the fabric to be sheared and / or the Cutting depth, even with dense pile, essential compared to the state of the art can be increased and still maintain an evenly sheared fiber pile becomes.
Die erfindungsgemäße Lösung besteht für die eingangs genannte Scherwendel darin, daß die Hiebe als bogenförmige Ausnehmungen der Brustfläche ausgebildet sind. Vorzugsweise soll die Tiefe der Hiebe senkrecht zu der Brustfläche größenordnungsmäßig mindestens gleich der parallel zu der Schneide gemessenen Breite der Hiebe sein.The solution according to the invention exists for the shear helix mentioned at the beginning in that the blows are formed as arcuate recesses in the chest surface are. The depth of the blows should preferably be perpendicular to the chest surface on the order of magnitude at least equal to that measured parallel to the cutting edge Width of the blows.
Durch die Erfindung werden zugleich das zur Aufnahme von Fasern zur Verfügung stehende Volumen des einzelnen Hiebs maximiert und die Hiebschneidkante auf fast die ganze Länge des bogenförmigen Hiebs ausgedehnt. Daher kann eine der Flordichte, Schneidtiefe und der Stoffbahntransportgeschwindigkeit entsprechend große Fasermenge im einzelnen Hieb aufgefangen werden, ohne daß die Fasern seitlich parallel zur Schneidkante des Gegenmessers ausweichen oder - wie bei einem in der genannten DE-AS 24 04 837 beschriebenen, herkömmlich keilförmigen Hieb - in eine Keilspitze abgedrängt werden können. Das bogenförmige Hiebvolumen nach der Erfindung bietet nämlich nicht nur Platz für wesentlich mehr Fasern als die bekannten flachen Keile, sondern es hat auch keine Keilspitzen, in die Fasern ausweichen könnten. Der Herstellungsmechanik entsprechend kann die Bogenform aus einer Vielzahl von im wesentlichen ebenen Elementen aufgebaut sein. The invention at the same time makes it available for holding fibers standing volume of the individual cut is maximized and the cutting edge is cut open extended almost the entire length of the arcuate slash. Therefore one of the Pile density, cutting depth and the material web transport speed large amount of fibers can be caught in a single cut without the fibers dodge laterally parallel to the cutting edge of the counter knife or - as with a conventionally wedge-shaped described in said DE-AS 24 04 837 Slash - can be pushed into a chisel tip. The arcuate slash volume namely, according to the invention not only offers space for significantly more fibers than the known flat wedges, but it also has no wedge tips in the fibers could dodge. According to the manufacturing mechanics, the arch shape be constructed from a plurality of essentially flat elements.
Gemäß weiterer Erfindung können sich die erfindungsgemäßen Hiebe im Mittel etwa kreisbogen-, ellipsen- oder parabelförmig in die Brustfläche hineinerstrecken. Im Rahmen der Erfindung liegt auch jede andere Bogenform, die ein maximales Aufnahmevolumen für Fasern und eine möglichst lange Schneidkante garantiert. In diesem Sinne besonders bevorzugt wird ein etwa parabelförmiger Querschnitt der Hiebausnehmung, dessen Parabelachse etwa senkrecht zu der Schneidkante des Gegenmessers steht. Gegebenenfalls sollen sich die parabelförmigen Querschnitte etwa symmetrisch in Richtung der Gegenmesserschneidkante öffnen. Wenn die Schneide der Scherwendel um den Winkel α der Wendelsteigung gegen die Schneidkante des Gegenmessers geneigt ist, steht dann die Parabelachse mit dem Winkel 90°-α schräg zur Scherwendelschneide. Im allgemeinen werden die Hiebe als zueinander parallele Nuten in die Brustfläche eingebracht. Beim Nachschleifen der Schermesser bleibt dann die Keilform unverändert erhalten.According to a further invention, the blows according to the invention can approximately average Stretch into the chest surface in the shape of an arc, ellipse or parabola. in the The scope of the invention also includes any other arch shape that has a maximum receiving volume guaranteed for fibers and the longest possible cutting edge. In In this sense, an approximately parabolic cross section of the Slash recess, the parabolic axis of which is approximately perpendicular to the cutting edge of the Counter knife stands. If necessary, the parabolic cross sections open approximately symmetrically in the direction of the counter knife cutting edge. If the Cut the shear helix by the angle α of the helix pitch against the Cutting edge of the counter knife is inclined, the parabolic axis then stands with the Angle 90 ° -α at an angle to the shear helix. Generally the blows introduced as parallel grooves in the chest surface. When regrinding the shear knife then retains the wedge shape unchanged.

Bevorzugt soll die Tiefe der Hiebe senkrecht zu der Brustfläche soll größenordnungsmäßig mindestens gleich der parallel zur Schneide der Scherwendel gemessenen Breite der Hiebe gemacht werden.It becomes a shear helix for the shear cylinder of a shearing machine for shearing described a fabric.

According to the slashes are arcuate recesses the chest surface of the scissor coil. Preferably, the depth of the Slashes perpendicular to the chest surface should be at least equal in size the width of the blows measured parallel to the cutting edge of the shear helix become.
