the wire 30 passes through a dryer 34 which includes actuators 36 that can vary the cross directional temperature of the dryer a scanning sensor 38 which is supported on supporting frame 40 continuously traverses and measures properties of the finished sheet in the cross direction scanning sensors are known in the art and are described for example in u s pat no 5 094 535 to dalquist u s pat no 4 879 471 to dalquist et al u s pat no 5 315 124 to goss et al and u s pat no 5 432 353 to goss et al which are incorporated herein the finished sheet product 42 is then collected on reel 16 as used herein the u201c wet end u201d portion of the system includes the headbox the web and those sections just before the dryer and the u201c dry end u201d comprises the sections that are downstream from the dryer typically the two edges of the wire in the cross direction are designated u201c front u201d and u201c back u201d alternatively referred as the u201c high and u2018 low u201d with the back side being adjacent to other machinery and less accessible than the front side the system further.
