Adjustment of Working Pressure of Compressed Air and Adjustment of Cylinder Speed The pressurereducing valve for adjusting the working pressure of pressed air is mounted on the pneumatic control panel at right rear side of the headstock. The pressurereducing valve for adjusting the inlet pressure of pressed air from the air source is on the three main ponents for pressed air source treating at the lower part of the control panel. The pressure of the pressed air from the source should be adjusted to MPa. It is shown by a pressure meter. The pressurereducing valves for adjusting working pressure of other air ways are located at the left upper part of the control panel. The adjusting pressure for each pressurereducing valve is shown by its pressure meter respectively. The adjusting for disk pressure is MPa (it cannot be higher than MPa). The adjusting for calender pressure is ～ MPa. The adjusting for brake pressure is ～ MPa, the actual pressure should be determined according to the braking time. The normal braking time should be controlled within 1 ～ 3 seconds. The speed of most cylinders is adjustable. The adjusting device is oneway flowregulating valve of connector type. Normally those valves are mounted on the two ends of cylinders. Just adjust the adjusting screw on the valve, the speed of cylinder can be adjusted. The oneway flowregulating valve for controlling the lap pushing cylinder is mounted on the outlet air way of the solenoid valve for direction changing on the pneumatic control panel. That is for convenient adjustment. UNILAPPER FA356 INSTRUCTION MANUAL １９ Adjustment of Pressure for Lap Loading The requirement for adjusting the working pressure of cylinder for lap loading is that the load values for small lap and for big lap should be different, in order to keep the density of lap be as uniform as possible during the whole winding procedure. The pressure control for lap loading is realized by the pressurereducing valve for stroke, which is located at the front upper side of left machine frame piece. The Ushaped plate and adjustable Ushaped plate (2). They are all mounted on the lifting rack (3), and are going up and down with the changing of diameter of lap. When adjusting the adjustable Ushaped plate, it is possible to make the sizes ―A‖ and ―B‖ at two ends be different. When the Ushaped plate is going up with the lifting rack, the adjustable Ushaped plate presses gradually the contact of pressurereducing valve (4) for stroke. Thus the pressure at the outlet of that valve will change. The value of pressure changing can be indicated by the pressure meter (5). Because the outlet is connected to the chamber (without piston rod) of cylinder for lap loading, the pressure for whole winding procedure is therefore controlled. The concrete adjusting range is: When the lifting rack is at its lowest position, adjust the reading of pressure meter to ～ MPa. The maximum pressure for lap doffing is ～ MPa. Loose the fixing screw (6), adjust the position of adjustable Ushaped plate to adjust the pressed extent of contact of pressurereducing valve for stroke (4). Therefore to decide the size ―A‖. UNILAPPER FA356 INSTRUCTION MANUAL ２０ Put the lifting rack at the height of maximum lap diameter. Adjust the dimension of ―B‖ by adjusting the position of adjustable Ushaped plate (2). Make the indication of pressure meter be the maximum pressure value. Be cautious that the pressure setting should not be higher than MPa for the maximum loading. For the adjustment of adjustable Ushaped plate, be cautious that dimension difference of ―A‖ and ―B‖ cannot be bigger than 7 mm. The flowregulating valve (1) shown in makes a sideway at the inlet of pressurereducing valve for stroke. The inair flows to the outlet of pressure reducing valve for stroke through the flowregulating valve, therefore produces a lower surplus pressure. It has a certain damping function in the pressurereducing valve, and exhausts surplus air from the exhausting outlet of the pressurereducing valve for stroke. Therefore to maintain pressure at the outlet stable. The damping pressure can be adjusted with the screw on flowregulating valve (1). After finishing adjustment of the pressurereducing valve for stroke and the flowregulating valve, set the controlling pressure of the pressure relay within the range of ～ MPa. It can be adjusted with the pressure adjusting screw of the pressure relay. Adjustment of Braking Device When the cylinder (5) is in exhausting status, the clearance between the brakeshoe and the brake disk should be ～ 1 mm. The clearance can be adjusted with the adjusting screw (4), The nut must be locked after adjusting. Adjustment of Suction and Startingup System The suction duct is interlinked to the air box (1) and connects with the hollow disk shaft (2). A sealing plate (3) is fixed on the rear side of the air box by a bolt (5). The position of the sealing plate (3) should be adjusted to seal the hole of disk shaft when the disk UNILAPPER FA356 INSTRUCTION MANUAL ２１ is open. And when the disk is closed, the sealing plate does not touch the endface of disk shaft. The hole of disk shaft is open, and it is possible to suck air from inside of the bobbin and to produce a negative pressure. Therefore the batt can be sucked on the surface of the bobbin, and a successful startingup can be realized. for adjusting the position of sealing plate, first loose the nut (4), then adjust the blot (5). Fasten the nut (4) after finishing adjusting. When starting suction, the vacuum inside the air box should reach at least 20 mm watercolumn (it can be measured with a Utype
