Abstract
A high speed sheet stacker includes a plurality of vacuum transport sub-assemblies interdigitated with an adjacent sub-assembly and provided with a spatial pitch that is less than or equal to a predetermined shingle distance. The collective vacuum transport assembly can thus acquire shingled sheets and transport the shingled sheets as a set, with each sheet being offset by at least one shingle distance. As a result, speed and acceleration requirements for the vacuum transport and the sheets being transported are greatly reduced compared to conventional vacuum transports that essentially transport sheets singularly. A shingled transport zone may be provided upstream of the vacuum transport system to accommodate sheets of varying size. In various embodiments, three to five vacuum transport sub-assemblies are provided to transport three to five sheets as a set.
