ABSTRACT:
A stacker assembly for receiving generally flat documents, such as mailing envelopes and flats, in on-edge relation and maintaining the documents in upstanding side-by-side stacked relation as they accumulate in the stacker assembly. A receiving station is supported at one end of a horizontal support plate and guides successive incoming documents into stacked relation transverse to the longitudinal axis of the stacker assembly. A stacker plate is supported to engage the forwardmost document in the stack and is movable longitudinally of the stacker assembly in response to accumulation of documents in the stacker. Means in the form of a negator spring and a wedge plate cooperate with the stacker plate in a manner to apply a variable pressure against the documents so as to accommodate both thin lightweight and heavier documents in the stack while maintaining them in upstanding relation.
