Abstract
Business form components are stacked to separate them into different jobs, and after stacking are synchronously conveyed together to a pressure sealer, or similar device, for sealing the components together into a business form or are conveyed to subsequent operations such as secondary stacking into larger stacks. Each component moves from an aligner/feeder to a stacker, moving up an incline of a continuously running conveyor belt so that each successive component passes underneath any previous components in a stack. When a movable stop against which the components are held rotates out of the way, a top roller near the trailing ends of the components pinches them against a bottom roller so that the components move together away from the stacker in register with each other. A sensor senses each component as it passes to the stacker, and when the desired number for a stack have moved past the sensor, a controller controls the operation of the stop and top roller to allow the continuously running conveyor belt to move the stacked components out of the stacker.
