ABSTRACT:
An apparatus for processing a particulating printing plate includes an outer casing having an entrance end and an exit end, and a pair of opposed side portions. The exit end of the apparatus is disposed at an upward tilt relative to the entrance end. In addition, one side portion is disposed at an upward tilt relative to the other side portion. A pair of entry rollers is disposed one above the other adjacent the entrance end of the outer casing for receiving the plate and conveying it in a horizontal direction. A first sprayer for spraying developer solution onto one surface of the plate is disposed adjacent the downstream ends of the entry rollers. First and second brushes are disposed one above the other and adjacent to the first sprayer for brushing away unwanted coatings on the plate after it has been sprayed. The upper brush is an individually rotatable roller which is adapted to be rotated in a direction opposite to that of the conveyance of the plate. The upper brush is rotatable relative to the bottom brush in a direction opposite to that of the direction of the conveyance of the plate and the rotation of the lower brush, and at a speed greater than that of the entry rollers. A second sprayer is disposed adjacent the brush members for spraying fresh developer solution onto the plate after it has been brushed. A pair of squeege rollers is disposed adjacent the second sprayer for removing excess solution from the plate and directing it towards the exit end of the outer casing.
