本機是將棉、毛、化纖及混紡紗的兩股或者三股合為一般用于捻線或倍捻的紡織設備。

主要特點：

一、機身簡潔易于安裝與調整。

二、并紗線速度高達600米/分，這是目前國內外公認的理想高速級并紗速度。

三、斷紗自停系統(tǒng)是本機獨有的機械與電子相結合的系統(tǒng)。其中引發(fā)動作的磁電傳感器電路環(huán)節(jié)少，因此，比光電式、電容式、壓電式等任何一種傳感器反應快，而且抗環(huán)境干擾性強，所以電機斷紗后被卷繞的紗頭幾乎沒有浪費，達到先進水平。

四、本機設有電切斷裝置，電切斷裝置在切斷股紗的同時，紗鏟將運轉中的筒紗托起使其脫離導紗槽筒，并將股紗頂出槽筒的溝槽，另外，電切斷裝置還能握持未斷股紗從而方便了操作。

五、筒錠支承部件具有使卷繞筒子對導紗槽筒的壓力從小紗到大紗，按從大到小有規(guī)律的變化，其變化規(guī)律還可按工藝要求進行調節(jié)，這一功能的設置是筒子成形質量提高的有力保證。

六、為了方便管理，本機還在每錠上設置了預置式數(shù)顯電子計長表，這種表使用方便計長準確，是現(xiàn)代管理的必備手段。

七、本機的紗路短易于操作。

八、本機還設置了變頻調速裝置，使并紗線速度在200米/分至600米/分范圍內無級調控。

九、用戶也可選配空氣捻接器。

The machine is used for doubling two or three yarn of cotton, wool, chemical fiber or their bledds to plied yarn which to be used for Twister or Two-for-one Twister.

The main feature:

1.It is easy to erect and adjust with the simple structure.

2.The doubling speed is up to 600m/min, it is comfirmed by the users both in abroad and home.

3.The Auto-stop mechanism for break-end is owned only by the machine which is combined with the mechenics and electronics, and there are few magnet electronics elements in it.So the sensor reacts fasters than photoelectricity, capacitance and piezoelectricity ect. any other styles. And it has strong ability to untiinterference.So the yarn winded after break end is nearly no waster.

4.The machine is equipped with electricity cuttting devicre.It can cut the plied yarn and hold up th e bobbin which is running to make it away from drum and prop up plied yarn out of the plow groove of the drum with the yarn shovel at the same time. The electric cutting device can hold the unbreakaged yarn for easy operation.

5.The supporting part of the bobbin can make the pressure from winding bobbin to guiding drum change with the diameter of the bobbin tegularly according to the technological requirements. This kind of design can be ensured by the quality of shaped bobbin.

6.In order to manage, the machine is equipped with presetting digital display electronic length-counting meter to tach spindle with the operation easliy and the counting length exectly.

7.The machine is easy to operate because its yarn path is short.

8.The machine is also set converter to control the doubing speed in the range of 200m/min~600m/min.

9.The air-vortex Twister is optional.
