ABSTRACT:
A bracket carries a plurality of wafer members stacked across the width of a fiber band. At least one wafer member is stationary with respect to the bracket, and at least one wafer member is movable, in a direction normal to the fiber laydown surface. In-line apertures are provided through the wafer members, and a fluid operated bladder is commonly disposed through the apertures and inflated to bias the movable wafer members against the fiber laydown surface when the stationary member is impressed against the fiber laydown surface. The wafer members have a compliant contact surface for contacting the band of fibers, and the movable wafer and contact means may thereby float with respect to the bracket to adapt to contour variances across the band width on the laydown surface.
