Description

Um sich von der Neigung der Textilstoffe zur Faltenbildung ein Bild, zu machen, erzeugte man bisher durch Zusammendrücken des Stoffes mit der Hand Falten darin und stellte den Zeitpunkt fest, an welchem die Falten wieder verschwanden. Die Erzeugung der Falten von Hand hat jedoch den Nachteil, daß 'die Faltenbildung durch den Prüfenden beeinflußt wird und somit keine genau vergleichbaren Ergebnisse erhalten werden. Zur Vermeidung dieses Nachteils dient der Erfindungsgegenstand, eine Vorrichtung, bei der die Falten in der Stoffprobe auf maschinellem Wege erzeugt werden.In order to get an idea of the tendency of textiles to form wrinkles, was created up to now, by squeezing the fabric with your hand, you creased it and determined the point in time at which the creases were made disappeared again. The production of the folds by hand, however, has the disadvantage that 'the formation of folds by the examiner is influenced and thus no exactly comparable results are obtained. To the This disadvantage is avoided by the subject matter of the invention, a device in which the folds in the fabric sample are produced by machine.

In Fig. ι ist die neue Vorrichtung in der Gesamtansicht wiedergegeben. Die senkrechte Spindel a, die durch die Winkelräder d, d und die Handkurbel« in der Pfeilrichtung in Umdrehung versetzt wird, trägt einen Kopf & zur Aufnahme der zu prüfenden Stoffprobe. An dem Kopf b ist eine über die Rolle C1 geführte und durch ein Belastungsgewicht g in Spannung gehaltene Schnur c befestigt, die sich beim Drehen der Spindeln spiralförmig um die Stoffprobe wickelt und dadurch die Falten erzeugt (s. Fig. 2).In Fig. Ι the new device is shown in the overall view. The vertical spindle a, which is set in rotation in the direction of the arrow by the angle wheels d, d and the hand crank «, carries a head & for receiving the material sample to be tested. A cord c , which is guided over the roller C 1 and held in tension by a loading weight g, is attached to the head b , which cord wraps itself spirally around the material sample when the spindles are rotated, thereby creating the folds (see FIG. 2).

Nach Fig. 4 wird zu diesem Zweck überAccording to Fig. 4 is used for this purpose

den Kopf b mit der Stoffprobe s eine drei- - armige Klammer O1 gedrückt, an der die Schnure befestigt ist. Man läßt diese eine bestimmte Zeit auf die Probe wirken, damit sich die Falten genügend stark ausbilden können.the head b with the fabric sample s a three-armed clamp O 1 pressed, to which the cord is attached. This is allowed to act on the specimen for a certain period of time so that the wrinkles can develop sufficiently.

Um den Einfluß der Körperwärme auf die Faltenbildung der Stoffe zu berücksichtigen, kann eine Einrichtung zum Erwärmen der Stoffprobe vorgesehen werden. Die Erwärmung der Stoffprobe kann in an sich bekannter Weise durch einen elektrischen Widerstand oder durch warmes Wasser erzielt werden. In letztem Falle fließt das z. B. auf 37° C erwärmte Wasser aus einem Vorratsbehälter durch das im Innern der Spindel a angeordnete Rohr h nach dem Kopf b und dann durch das RohrÄ wieder ab.In order to take into account the influence of body heat on the wrinkling of the fabrics, a device for heating the fabric sample can be provided. The material sample can be heated in a manner known per se by an electrical resistance or by warm water. In the latter case, the z. B. heated to 37 ° C water from a storage tank through the arranged inside the spindle a tube h to the head b and then through the tube Ä again.

Der Kopf δ der Spindeln ist nach Fig. 3 dreikantig; er kann jedoch beliebig geformtThe head δ of the spindles is according to FIG. 3 triangular; however, it can be of any shape
