摘要： A yarn splicing device for piecing spun yarns without knots. It contains a yarn splicing chamber and a small pipe through which fluid flows, at a distance from the yarn splicing chamber. The small pipe serves to receive a yarn end and to prepare it for the splicing process. The small pipe has a roughened inner surface which makes contact with the yarn end in a battering manner. In the process for the yarn end preparation, the small pipe is traversed turbulently by a fluid. The yarn end is battered by the turbulent flow against the roughened inner surface of the small pipe until the yarn end is free of twist.

摘要： A process and a device for the air-conditioning of spinning material located in a container. The spinning material is air-conditioned for processing in a spinning machine which is essentially surrounded by any room climate. The spinning material is exposed in the container to a climate which is independent of the room climate. This causes, at least, the spinning material to be taken next out of the container to be air-conditioned in such manner that it is in an optimal climatic state for such further processing. Outlet openings of at least one air-conditioning duct or an air-conditioning plant are located on the container so that an air-conditioned fluid flows out of the outlet openings on at least the spinning material to be taken out next and the spinning material is in an optimal climatic state for further processing as it is then processed further.
摘要翻译：一种用于空调位于容器中的纺丝材料的方法和装置。纺纱材料在纺织机中进行空调处理，纺纱机基本上被任何室内气候包围。纺纱材料在容器中暴露于独立于室内气候的气候。这至少导致纺丝材料被从下一个取出的容器中进行空调，使得其处于用于进一步加工的最佳气候状态。至少一个空调管道或空调设备的出口开口位于容器上，使得空气调节的流体至少在待纺出的纺丝材料上从出口开口流出，随后将纺丝材料在最佳的气候状态进一步处理，然后进一步处理。

摘要： For the formation of a thread withdrawal nozzle for an open-end spinning apparatus which possesses a spin rotor, a thread contact surface (32) of the nozzle is provided with projections (36), which projections close at an obtuse angle (&agr;) with the thread contact surface (32). Thereby, a satisfactory twist propagation is obtained to the fiber entwinement point, so that, in this manner, a softer thread can be produced. Advantageously, the thread is not roughened by this treatment.
摘要翻译：为了形成具有旋转转子的开口纺丝装置的拔丝嘴，喷嘴的螺纹接触表面（32）设置有凸起（36），凸起以钝角（α）与螺纹接触表面（32）。由此，获得令人满意的扭转传播到纤维交织点，从而可以制造更柔软的线。有利的是，这种处理丝线不会粗糙。
