AUTO GUIDES FOR WIRE AND FELT

 

APPLICATION

 

Auto guides for Wire & Felt are used for guiding the wire & felt accurately so that the damage and consequent loss in production is completely avoided.  Installing the reliable and well proven pneumatic automatic guiding system is an easy way to solve the wire & felt guide problem. 

          

                      

 

MOUNTING

 

The guide should be mounted on a roll which ideally is positioned between two stationery rolls.  The angle of wrap should be 1300 to 1450 for wires and 1300 to 1450  for felt to best guiding effect.  The distance between the two stationary rolls should preferably be equal to the width of the wed.  The palm must hang vertically to provide sensitive motion.  Position of the wed is adjusted by moving the controller horizontally.  The actuator can be mounted in any desired position –horizontally, vertically or angle in between. 

 

OPERATION

 

The actuator should operate in the middle position to insure the possible field of action.  The adjustment can be made by operating the hand guide as shown in the assembly drawing.  The actuator is connected to controller through removable hoses.  The control valve & palm assembly are mounted in such a way that the palm is always in contact with wire or felt.  So, that it continuously sense the cross movement the wire or felt.    The controller works with a proportional modulated action and gives an extremely accurate control.  During the operation the controller casing is pressurized to avoid penetration of dust and moisture to the inside.  The controller palm is delicately balanced and follows the edges of wire or felt with a very gentle pressure. 

 

MATERIAL OF CONSTRUCTION

 

The controller is made of brass and pilot valve, palm holders and roller palm of stainless steel.  Guide brackets, bearing housing and double action cylinder are made of closed grain cast iron.

OPERATING SYSTEM :-

 

The fundamental idea of the GTC pneumatic tracking device is to guide the paper machine wire or felt in a straight path.  The paddle will feel the slightest linear movement and will correct to a sable position by moving the guide roll in the appropriate direction.  Under severe conditions in Paper and Pulp & Board Machines are GTC tracking device will function perfectly. 

 

Any movement of the wire or felt from a straight path will move the paddle in a specific direction.  The paddle will in turn operate the control valve which re-directs the incoming air to the appropriate side of the  guide connected to the guide roll.  Movement of the guide roll will bring the wire or felt back into a straight path.
