Roller Displaced Guiding Systems

S.T.G. Steering Frames: Roller Displaced Steering Frames are designed to create both a dynamic and static correction for true intermediate guiding control. The steering guide swings immediately when the material runs out of alignment, positioning the edge of the web back to the neutral point of the sensor. The correcting motion opposes the tendency for the web to wander from the guiding point.

Single Roller Steering Frames: Incoming and exiting webs must wrap steering roller at 90 degrees. For rigid webs of special applications please call us.

Typical Dimensions for use with Flexible Webs:

• A = Entry: 2 to 3 times material width
• B = Exit: 5 to 1 times material width
• C = Sensor: As close as practical to exit idler roller without interfering with swing.
• D = Web support idler roller: can be used if needed providing web does not wrap roller radius.
