抽吸组件还包括文丘里喷射件而不是大的抽吸马达，以用于从纬管拾取纱线端部。
The suction assembly also comprises a venturi jet (5) instead of large suction motors, for picking the yarn end from the cop (4).
文丘里喷射件被设计成使得其接收压缩空气并将空气在与纬管相反的方向上吹动到抽吸管内部，即，向纬管上游吹动空气。
The venturi jet (5) is designed in such a way that it receives compressed air and blows the air inside the suction pipe (2) in the direction opposite to the cop (4), i.e. blows air upstream of the cop (4).

抽吸管可定位在纬管上方的预定高度处。
The suction pipe (2) may be positioned at a predetermined height over the cop (4).
至少一个文丘里喷射件可与抽吸管固定，并且文丘里喷射件可从压力供应端口接收压缩空气。
At least a venturi jet (5a) may be affixed with the suction pipe (2), and the venture jet (5a) may receive compressed air from a pressure supply port.
压缩空气通过所述文丘里喷射件的收缩区段的运动可在抽吸嘴中产生真空，以将断纱端部从纬管抽吸到抽吸管中。
A movement of the compressed air through a constricted section of the said venturi jet (5a) may create vacuum in the suction mouth (3) to suck the broken yarn end from the cop (4) into the suction pipe (2).
