Partially Cantilevered: The roll support arbor is cantilevered, and the dancer system is supported at both ends.

Fully Supported: The removable air shaft is supported at both ends, and the dancer system is supported at both ends.

AUTOMATIC WEB GUIDING:  For wider stands that require automatic web guiding, the stand is constructed so that it rides on linear anti-friction bearings which are mounted on the base plate. An electro mechanical web guide system employing a linear actuator shifts the upper portion of the stand in response to signals from the web position sensor. For narrow stands, a web offset pivot guiding system is provided when automatic web guiding is specified.
