Abstract
Apparatus to sense and guide the edge of a backing material having a raised surface. A double sensor is provided to either sense the edge of applied substance or the edge of the backing material or selvedge. The double sensor employs a pair of flag members to vary the pressure of a fluidic sensing device in response to the position of the selvedge to automatically control the position of a selvedge protection device.
