    • A running yarn is spliced into a running tow by entangling filaments of the tow with and about filaments of the yarn with an air-jet device, the leading portion of the yarn is severed to leave a small protruding tail, and the tail is entangled within the tow with a second air-jet device. The air-jet devices comprise two halves which are separated and positioned on each side of the tow until a splice is to be formed; they are then closed to form cylindrical treatment chambers of diameters which impart a rounded shape to the tow, so that filaments are entangled about the yarn by the air jets. The air-jet devices are preferably designed to provide a forwarding action on the filaments.
    • 通过用喷气装置缠绕丝束丝和长丝,将运行中的纱线拼接成运行的丝束,纱线的前导部分被切断以留下小的突出的尾巴,并且尾部被缠结在 带有第二喷气装置的丝束。 喷气装置包括两个分隔开并定位在丝束两侧的两个半部,直到形成接头; 然后将它们封闭以形成具有圆形形状的丝束的直径的圆柱形处理室,使得细丝通过空气射流缠绕在纱线周围。 喷气装置优选地设计成在长丝上提供转向动作。
