Claims1
A device for washing and drying scorecards comprising;
- a tank having an inlet aperture and an outlet aperture;
- means for conveying a scorecard edgewise through said tank, said conveying means including in part a pair of revolving feeder rollers located at said inlet aperture which receive and pull said scorecard into said tank and propel it through a guide means downward into a cleaning fluid disposed in said tank;
- a scrubbing station submerged in the cleaning fluid contained in said tank whereby said fluid is supplied to the scorecard during the scrubbing operation, said scrubbing station including multiple revolving cylindrical brushes positioned above and below said scorecard to receive it from said feeder rollers and to propel it as it passes through said scrubbing station, said brushes being disposed in a vertically staggered arrangement which causes the scorecard to undulate as it passes through the brushes and whereby both sides of said scorecard are washed simultaneously, said brushes positioned above said scorecard revolving in a direction opposite to said brushes positioned below said scorecard and propelling said scorecard through said scrubbing station to a second guide means and through said second guide means to a drying station;
- means for drying said scorecard at said drying station comprising a pair of revolving wringer rollers operable to remove said fluid from said scorecard and pull it from said scrubbing station and propel it through said outlet aperture;
- means for adjusting the compressive tension of said feeder rollers and said wringer rollers upon said scorecard as it passes between said pairs of rollers;
