ABSTRACT:
A distinct conveyor assembly allows a business form sealer--such as a pressure sealer--to operate with forms that have been detached from a continuous supply. Individual forms are detached from the continuous supply while being conveyed in a first direction, to form shingled forms having irregularly positioned side edges. The forms are deshingled by conveying them from the detacher at high speed (e.g. an increase in speed of about ten times or more), and they are registered while being conveyed in the first direction at high speed. Registration may take place by moving the forms against one side edge, or moving them between funnelled side edges to ultimately engage straight guides on both side edges. After registration, the forms may be fed directly to the sealer, or into the top of a hopper, and then withdrawn from the bottom of the hopper and passed through a folder before being fed to the sealer.
