摘要： The device (1) comprises a first roller (3) rotatable about a first rotation axis (3A) and a second roller (5) rotatable about a second rotation axis (5A), parallel to the first rotation axis (3A). The two are in mutual contact and define between them a yarn passage (7) and at least of them is motorized. The device further comprises 5 guide members (9) defining a feed path of at least a yarn (F; F1, F2, F3, F4), associated with the yarn passage (7) between the first roller (3) and the second roller (5). The guide members (9; 13) are movable with respect to the rollers (3, 5) in a direction substantially parallel to the first rotation axis (3A) and to the second rotation axis (5A), so as to take the yarn path temporarily outside the mutual contact 10 area between the rollers.

摘要： A multi-filament yarn (100) includes interlace nodes (103) disposed along the length of the yarn. The yarn (100) has variable retained heat shrinkage potential at segments along its length such that segments of said yarn containing the interlace nodes (103) have a retained heat shrinkage potential in excess of segments of said yarn between the interlace nodes (102). Upon application of uniform heat to the yarn (100), the segments containing the interlace nodes (103) exhibit enhanced shrinkage and self texturing relative to the segments between the interlace nodes (102). A fabric formed with the yarn (100) prior to the final heating process will present a varied and random appearance after application of the final heating process due to the differentiated shrink segments. Pile fabrics formed with the yarn (100) as the pile yarn prior to the final heat treatment will have piles of varying height due to the differentiated shrink segments, and will also have a varied or random appearance.
摘要翻译：复丝纱线（100）包括沿纱线长度设置的交织节点（103）。纱线（100）在沿其长度的片段处具有可变的保持热收缩电位，使得包含交错节点（103）的所述纱线的片段具有超过所述纱线在交织节点（102）之间的片段的保持的热收缩电位。在对纱线（100）施加均匀的热量时，包含交错节点（103）的片段相对于交错节点（102）之间的片段表现出增强的收缩和自纹理化。在最终加热过程之前用纱线（100）形成的织物将在施加最终加热过程之后由于不同的收缩段而呈现出变化且随机的外观。在最终热处理之前用纱线（100）形成的绒头织物将由于不同的收缩部分而具有变化的高度的堆，并且还将具有变化或随机的外观。

摘要： Methods of forming a fiber are provided. The methods include subjecting a preform to a thermal drawing process to draw the preform into a fiber. One of the methods further includes applying, at intervals, a compressive force to sections of the fiber along a length of the fiber during the thermal drawing process to reduce a dimension of the sections to form the fiber into an accordion-like fiber. Another of the methods further includes inducing a relative rotational movement between the preform and a region of the fiber during the thermal drawing process to twist the fiber until the twisted fiber becomes coiled to form a spring-like fiber. According to further embodiments of the present invention, fiber actuators, fiber bundle and a method of forming the fiber bundle are also provided.

摘要： Methods, systems, and devices for changing cross-sectional sizes and/or shapes of flat braided sutures and the resulting constructs are disclosed. The flat braided sutures can have a textile first cross-sectional shape that can be changed to a textile second cross-sectional shape. The systems can have a heater and a die. The flat braided sutures can be movable through the heater and the die. When the flat braided sutures are in the heater, the flat braided sutures can be heatable from a textile first temperature to a textile second temperature greater than the textile first temperature. When the flat braided sutures are at the textile second temperature, the textile first cross-sectional shape can be changeable to the textile second cross-sectional shape.

摘要： Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Erzeugen von Verflechtungsknoten in einem multifilen Faden. Hierbei wird ein Luftstromimpuls durch eine Düsenöffnung quer auf den Faden gerichtet. Zur Erzeugung einer kontinuierlichen Folge von Verflechtungsknoten wird der Luftstromimpuls periodisch mit einer Pausenzeit zwischen den Luftstromimpulsen erzeugt. Um eine unregelmäßige Fadenstruktur erzeugen zu können, wird erfindungsgemäß die Pausenzeit zwischen aufeinanderfolgenden Luftstromimpulsen fortlaufend geändert. Hierzu weist die erfindungsgemäße Vorrichtung eine die Düsenöffnung tragenden Düsenring auf, der mit einem Antrieb gekoppelt ist. Dem Antrieb des Düsenringes ist eine Steuereinrichtung zugeordnet, durch welche eine Rotationsgeschwindigkeit des Düsenringes zum Zwecke einer Änderung einer Pausenzeit zwischen den Luftstromimpulsen steuerbar ist.
