In a Paper Machine there are several forming wires and felts, called fabrics in general, that function to support the paper being manufactured. These Fabrics travel over a number of rolls in cyclical patterns. Since all these Rolls cannot be exactly aligned with each other, certain devices called the Guiding Systems are needed to keep the fabrics running properly in the centre of the rolls. A Wire and Felt Guiding System is composed of mechanical devices used to keep the fabric running properly in the centre of the rolls over which it travels. This is done by pivoting one end of the guide roll in the proper direction to correct the errant fabric travel. H & T Proportional Bellows Auto Guide avoids damage to wire or felt caused by their cross-directional movements, over running or pre-mature creasing and thus saves the resultant loss of production. An Auto Guide is the most convenient, reliable and economical device using mill's normal air supply for its auto operation. Principle of Guiding The guiding of fabrics is based on the principle that the fabric will always leave a roll perpendicular to its rotational axis. This is governed by the direction of fabric travel. This dictates that the fabric will always travel towards the end of the roll it encounters first. Hence, the Guide Roll is automatically moved to change the fabric travel. Design H & T Wire and Felt Guide mainly consist of a pneumatically operated automatic guide and a sensor to control the movement. The auto guide holds the bearing housing of one end of a roll and moves it back and forth using Air-pressurized Rubber Bellows. The sensor is a control device for the guide and regulates the air flow to each of the Guide Bellows. When triggered appropriately, the Rubber Bellow Swivels the Guide Roll, mounted on-site on the positioning unit, in any direction. An Edge Sensing Device is required to control the guide that continuously monitors the fabric run that minimizes wear by avoiding fabric run-off. It determines the actual position of the fabric and specifies its target position. The one supplied with the system is the contacting pneumatic type palm assembly.
