ABSTRACT:
A method of and apparatus for processing and stacking printed forms operatively connects three main features. First, a dual registering stacking interface that stages, registers, transports, justifies and stacks forms in which forms are delivered to a side-by-side holding area known as channels one and two, where they are held stationary and accumulate in a stack or continue feeding as separate forms. Second, a sequencer merger receives the forms from the dual registering stacking interface and dual registering stacking interface and directs the forms in a selected order and transports said forms to its output end as a stack of forms. Third, an improved access accumulator incorporates the physical separation of upper from lower transport belt assemblies. A separate upper transport assembly is installed using ball bearings as hinges on the existing upper output shaft, spring loaded ball stud latches are used to latch the upper assembly to the lower assembly via two alignment blocks on either side of the device. Spring loaded latches provide the capability to pass multiple stacked pages into the device at one time thus allowing more than one page to pass into the stack together.
