The Piston Guide - requires low maintenance - is fitted with a mechanical feedback unit and one-way restrictors, - is supplied with stop valves as an option, that retain the Guide position in the event of a pressure drop or pressure failure.

2.2 Functional description The fabric guiding system consists of the following components: - Pneumatic Piston Guide SR-694/696/697 or SR-994/996/997 - Control Valve SV-95.1-5 or SV-95-10 (used at the series SR-996 / SR 997) for detecting and guiding the fabric edge position. - Mechanical feedback unit. The felt / wire Guide is pneumatic. The Piston Guide consists of one or two pneumatic cylinders for performing the adjusting movements and a guide unit (rolling guide by means of supporting rollers for steel version or plastic sliding rails for stainless steel version) for accepting all forces that do not act in the direction of the adjusting movement. The Piston Guide can be installed in horizontal, inclined or vertical position, upright or overhead hanging. The Control Valve is a stepless pneumatic selector valve with a sensing unit. If the fabric position changes, the sensor paddle, which controls the Control Valve, is deflected. Depending on the direction of deflection, one cylinder chamber of the correction device is pressurized and the other is vented. If the fabric position is again corrected, the sensor paddle returns to the basic position (16° relative to the vertical, valve closed). Because of the pressure difference between the two chambers of the pneumatic cylinder, the Guide moves and tilts the guiding roll. Tilting the guiding roll influences the cross-machine direction of the fabric, and this effect is used for guiding. The valve in the control unit is opened more or less depending on the amount of excursion. This means that the Guide corrects slowly for small excursions and more quickly for larger excursions. As soon as the desired value matches the actual value (fabric in desired position), the system has been properly regulated, and the valve is closed.

Transport and Storage

4.1 Packaging The Piston Guide is pre-assembled and packed in boxes and wooden crates. All plain parts (bearing yokes, etc.) are treated with anticorrosive.

4.2 Transport regulations The equipment is dispatched by a qualified carrier. Nevertheless, damage and loss may occur. Thus the equipment must be inspected for completeness and transport damage immediately upon receipt. Check contents of the consignment against the shipping papers. Take photos of any damage discovered. Visible damage must be confirmed by the carrier immediately in writing. The extent and possible cause of the damage must be described. Refuse to accept delivery if these details are missing! Notify the relevant transport insurance company and JUD AG of any damage to the consignment by means of a damage certificate.

4.3 Transport regulations If possible, the Piston Guide should be transported in its original packaging to the site of installation. The boxes and wooden crates do not have any special points of support. Attention The Piston Guide may fall down if transported improperly. Possible consequences: Death or serious injuries due to crushing and bruising and/or damage to machinery and material. Preventive measures: Transport requires skilled personnel with knowledge of technical aspects of transport and mechanics.

FIX 1/3 x FB

2/3 x FB

FB.......fabric width The felt/wire wrap angle at the guiding roll should be between 20° minimum and 40° maximum. The Guide should be mounted on the median between the ingoing and outgoing fabric. This can be achieved by means of suitable supports underneath the Guide. The ratio of the distances between the preceding and following roll to the Guide should be 2:1 if possible. The felt/wire wrap angle at the roll following the guiding roll should also be a minimum of 20°. By using the mechanical feedback unit, sensing can take place both before and after the guiding roll.

5.2 Installation 5.2.1 Installation of Piston Guide 1.

Remove anticorrosive from all plain parts of the Piston Guide. To do so, dip a fluff-free cleaning cloth in the solvent and wipe off protective coating. Suitable solvents are paraffin, resolvent or naphtha.

CAUTION: Damage to bearings and paint Do not use any aggressive solvents (acetone, thinner, etc.). Cover any adjacent bearings so as to prevent solvent from entering the Piston Guide. 2.

Check mounting surface of installation site: If necessary, remove rust, rework and measure. If required, prepare spacer plates to be placed underneath. Measure distance X on opposite side of the Guide. (see sketch)

4.

Mark off this distance X at the point where the Guide is to be installed and drill the mounting holes for the Guide.

5.

Level the opposite side of the Guide to the same center height Y as the Guide. (see sketch)

6.

Assemble guiding roll on Piston Guide.

7.

Recheck the center height and the roll. Fix Guide to the mounting surface using: > SR 69X: 2 x M24 bolts. Fastening torque: Quality •A2-70: MA max = 608 Nm •8.8 : MA max = 675 Nm > SR-99X: 2 x M30- bolts. Fastening torque: Quality •A2-70: MA max = 571 Nm •8.8 : MA max = 1350 Nm

Mentioned fastening torques are approximate values at medium friction factor - fastening factor needs to be considered separatly. If the Guide is fitted with a sliding carriage, the center of the roll can be adjusted by manually positioning the guide with the sliding unit

Installation of Control Valve These operating instructions describes the installation of the SV-95.1-5 Control Valve. The procedure for installation of other types of Control Valves is described in the operating instructions for these Control Valves. In the zero point positioning of the Control Valve, the sensor paddle must be oriented at an angle of 16° from vertical in order to be able to maintain continual contact with the fabric edge and work smoothly in both directions. 1.

Mount support stand SV-30 in the clamping block, secured to the cross profile of the mechanical feedback unit. The support can be turned in any direction by means of the clamping block (standard type).

2.

Mount the Control Valve upright on the support stand SV-30 so that the air connections are facing away from the machine. Only a horizontally mounted Control Valve guarantees correct functioning!

3.

Push sensor paddle onto the camshaft. Do not tighten the fastening screw yet.

4.

Rotate the sensor paddle away from the fabric and insert the pin supplied into the hole in the housing. Allow the sensor paddle to lie against the stop pin.

5.

Rotate the control shaft making sure that the red mark of the guide disk is aligned with the mark on the housing.

6.

Hold the sensor paddle against the Stop and tighten the screw on the arm of the sensor paddle.

7.

Adjust the height of the sensor paddle so that it lies approx. in the center against the felt or wire.

8.

Hold the sensor paddle against the Stop and adjust the horizontal arm of the SV-30 so that the felt/wire lies at the required position on the sensor paddle.

9.

Remove the stop pin.

10. Connect the supply air of the Control Valve with the service unit (air must be filtered and oiled). Use pipes that are resistant to acids and lye solutions in the wire and press section. Use heat-resistant pipes in the dryer section.

5.3 Setting into Operation 1.

Fill the service unit with oil. - oil quality: heat-resistant, synthetic oil (clarify with your oil supplier),see chapter 6.2

2.

Set the air pressure to 5 - 6 bar.

3.

Move the sensor paddle to one side, the correction device must move out completely to one side. Move the sensor paddle to the other side, the correction device must move out completely to the other side.

4.

Adjustment of Guide movement and mechanical feedback unit. First determine the appropriate installation using the following overview. Then check the correct movement of Piston Guide. If the Guide does not move as specified when the sensor paddle is deflected in the direction of the arrow, the air lines between the Control Valve and Guide must be interchanged.

Check correct function of mechanical feedback unit. (The Guides are already set for the position in question; if installed according to plan, no changes should be necessary.) There are two possibilities available to link the threaded rod with the mechanical feedback unit (A and B). The type may sometimes vary from the illustrated type. Linking variant A

Linking variant B

Rotary arm Lock nut

thread rod

Lock nut Rotary arm

The correct variant is determined by means of the overview on page 23. By moving the sensor paddle in the direction of the arrow (away from the fabric) the Guide should carry out a controlled movement in the direction of the arrow. The mechanical feedback unit is linked to the carriage and it's movement should move the Control Valve away from the fabric edge. Change of the linking variant can be carried out without difficulty on site. In this case it is required to remove the locknut from the feedback unit to insert the thread rod into the opposite rotary arm and then retighten using the nut (please use screw locking such as Loctite!). The installation of the Control Valve and matching to the particular conditions are quite universally adjustable and can be changed without difficulty on site (constricted with the stainless version).

Thus, for reasons of space, the mounting for the Control Valve (support SV-30) can be shifted (evtl. inverted) from the inside of the machine to the outside of the machine (Fig. 1). The alignment of the stand SV-30 support can also be changed in length and angle as required (the stainless steel version's angle can't be changed).

The horizontal alignment of the control shaft must be correct for proper functioning of the Control Valves SV-95.1-5, SV-95-10!

5.

Run the fabric slowly and observe the course (CMD) of the fabric and the Guide. If the Guide movement is too slow or too fast, this can be changed by means of the one-way restrictor valves. Please note that the actuating force of the pneumatic cylindre can be changed by means of the air pressure at the service unit. The air throughput, which affects the adjusting speed, can be set by means of one-way restrictor valves.

5.4 Functioning of the mechanical feedback unit A change in the sensor paddle angle effects a change of the pressure conditions in the pneumatic cylinder of the control device because of the design of the Control Valve (continuously variable pneumatic valve). The compensation for these pressure differentials causes the control movement. Because of the rigid connection of the mechanical feedback unit to the bearing yoke/ support plate, the Guide movement activates a transverse movement (CMD) of the Control Valve (see illustration) caused by the parallelogram of the feedback unit.

The transverse movement of the Control Valve causes attenuation and therefore a "damping" of the control signal. This behaviour leads to a faster correction of the fabric deviation and a uniform straight run of the fabric, particularly at low machines speeds (including when the machine starts up. This particularly leads to lower wear of moving parts of the Guide because of the shorter travel distances.

5.5

Precautionary measures during installation and operation 1.

Roller bearing: The bearing assembly must consist of a fixed and floating bearing, whereby the floating bearing should be fitted at the Guide. The bearing assembly must be able to compensate for angular offset (e.g. self-aligning roller bearing).

2.

The bearing housing must not jam in the bearing yoke, i.e. there must be sufficient clearance.

3.

Lubricate between the bearing yoke drill hole and the bearing housing.

4.

Check whether the fastening screws of the Guide are properly tightened.

5.

Check whether the fastening screws for the top of the bearing yoke are properly tightened.

6.

Check that all the air lines are of adequate dimensions and in a serviceable condition and that the connectors are correctly tightened and leakproof.

7.

If it is necessary to perform a lot of work in the immediate vicinity of the Guide, a contact guard should be fitted at the bearing yoke to prevent drawing in with bruises or gashes caused by a sharp fabric edge.

8.

Avoid direct, constant water spraying onto the Guide. If necessary, install a screen.

Regular Maintenance Before carrying out maintenance and repair works: Switch off the overall system and prevent from being activated unintentionally (switch off the compressed air supply and attach warning sign).

6.1 Cleaning Cleaning interval:

Once a year for dryer section Twice a year for wet section, (wire and press)

The sliding rails, sliding guides and cam rollers must be checked for wear, dirt and damage. If there is severe dirt on the Guide, clean the Guide to guarantee proper functioning. Check the pneumatic cylinder regularly for leaks. If the cylinder is leaking, examine the piston rod and cylinder bore for damage. Replace any damaged parts before fitting new seals. If no damage can be found, the piston seal and piston rod seal must be changed. If the o-rings are still in good condition, they can be reused.

6.2 Lubrication and Recommended lubricant Cam rollers resp. sliding rails should be lubricated with a suitable grease during scheduled machine shutdowns. Proper are high performance multi-purpose greases according DIN KP2K-20 (e.g. Shell Alvania Grease EP2). The lubrication should be mentioned in the lubricating diagram of the paper machine. Cylinder walls are pre-lubricated with heat-resistant Siliconegrease on Li-basis (Chemplex SI400 medium from Fuchs Lubritech). Further lubrication of the cylinder is accomplished via the oil-laden air from the service unit. Service unit and Control Valve Use oil depending to the installation site and temperature at this environment. Hydraulic oil to DIN 51524-HLP of viscosity class ISO VG32 is recommended. These oils have a basic viscosity (at 40ºC) of 32 mm2/s and are therefore suitable for use in the wet section of the machine. Because the viscosity reduces with increasing temperature, oil with a higher basic viscosity (ISO VG150/220) should be used in the dry section.
