Abstract
A strand deflector used in the manufacture of continuous strands is shown and described. The deflector comprises a rigid surface which stretches across the width of the mat making machine and which is interposed between the strand feeders located above it and the mat making surface so that the strands fed toward the surface must deflect from the deflector surface before they are collected on the mat making surface. The deflector surface is adjustable in the vertical direction and the angle of deflection with respect to the flow of strand from the feeder may also be changed to any desired value.
