Whole stranding cage is support by front and back. Each stranding cage is driven by motor separately. And, it has slow speed electrically inch positioning device separately to load and unload bobbin. Each stranding cage has single wire pre-forming device which can make sure the single wires will not loose when the after stranding conductor section is off. Wire doubling holder and pressing holder are installed on one mould. Wire doubling holder can realize the founction of wire doubling and round wire stranding.The size of pressing wheel isΦ 130  ×Φ 40 ×64mm(diameter×inner hole×width), it is put vertically. It can compact sector wire, pressure can be adjusted by bolt. It is fast and convenient to change the pressing wheel.4.2.5    Single wire pay-off tension is pneumatically controlled.   Through electronic detection and electrical control, and through inlet pneumatical control proportional valve to adjust, single wire pay-off tension from full bobbin to empty bobbin can be constant. 4.2.6     Shaftless type pneumatic clamping. And, it has mechanical safety locking mechanism.4.2.7      Mechanical type wire broken protect. Electrical switches detection is exact and reliable. 4.2.8      Pneumatic brake.4.2.9    Each stranding cage equips one set side-bottom bobbin loading device.4.2.10       Each stranding cage equips one set safety fence, the two sides of the stranding body have fences. One side fence is fixed. For the other side, there is one part which can be opened. It is convenient to enter and exit for the operators. 4.3 Side bobbin loading device     4.3.1           Applicable bobbin                  PND6304.3.2           Side bottom bobbin loading device is mainly composed of bobbin bracket, direction guiding bracket, transmission mechanism and electrical system etc. 4.3.3           Electrically load and unload bobbin.4.4 Paper lapping device4.5 Meter counter4.5.1           Meter counter circumference metter         452.448 mm4.5.2           Meter counter accuracy error                0.25    % 4.5.3           Max. meter counter length                  100000m 4.5.4    Double active, upper and lower pressing wheels type, upper meter counter wheel spring buffering, inlet and outlet wires have wire guiding bracket. 4.5.5           It has mechanical meter counter and electronic meter counting founction.4.6   Φ2000 double active pulling machine                                        4.6.1 Pulling wheel dia.             Φ2500mm  4.6.2 Pulling linear speed             7.1   ~ 54  m/min 4.6.3 Max.

Main features5.1   This machine adopts whole type bobbin loading and unloading, pneumatic clamping, easy to operate. This shortens the time of doing the auxiliary working, and improves the producing efficiency. 5.2  Adopt pneumatic tension control, has automatic tension adjusting construction which can ensure tension constant. Then, make sure tension will not change when reel is full or shallow. Tension can be set and amended through pay-off tension.5.3  Each part of this machine adopts separate motor driving, the structure is simple and easy to operate. 5.4  Adopt programmable controller to command uniformly, coordinate the working condition of each electrical part. Adopt Siemens 6RA70 series full digital DC speed regulating device. Technology of electrical control system is advanced. It is easy to operate, and run reliably. 6. Total capacity of this machine             600KVA7.      Machine operating direction: right hand machine (when operator faces the machine to operate, pay-off is at left, take-up is at right.
