ABSTRACT:
In combination with a filtration machine of the type employing an endless belt of filter medium without beads on either of its edges, a pair of devices for aligning and dewrinkling the belt. Each of the aligning and dewrinkling devices includes a rigidly-mounted arm and a first cylindrical roller extending from the arm beneath the adjacent edge of the belt of filter medium. Also, each of the aligning and dewrinkling devices includes a second arm pivotably connected to the first arm and a second cylindrical roller extending from the second arm above the adjacent edge of the belt of filter medium so that a long nip line is defined between the rollers. A spring is connected between the ends of the two arms to urge the pivoted arm to rock to pinch the rollers together along the nip line to grip the filter belt. Also, a selectively-actuatable ram assembly is connected between the arms for selectively increasing the grip of the rollers on the belt.
