ABSTRACT:
A continuous sheet pickling line and apparatus therefor which embraces the concept of pickling sheets by passing them horizontally through a tank made of suitable material and so constructed as to hold a sufficient quantity of pickling acid as to permit the sheets to be completely submerged as they pass therethrough, certain of the support rollers for the sheets and drive gears and associated bearings also being submerged. The line and associated apparatus processes the sheets in one continuous operation during which the sheets are fed onto an entry conveyor from a pack, one sheet behind the other, whereafter they are processed while horizontally disposed through the pickling tank, sheet scrubber, drying conveyor, leveler, oiler and then stacked in a suitable piler. Provision is made to heat and agitate the acid within the tank and to control the acid level. Typically the sheets are conveyed through a tank 80 feet long on rolls fairly closely spaced, each roll being provided with a plurality of donuts, evenly spaced along the roll but staggered throughout the tank, thus providing the bottom side of the sheet with continuous exposure to the acid. Power to the rolls is supplied through a motor and conventional line shafting and right angle gear reducers, over the top of the tank and into a polypropylene gear arrangement.
