ABSTRACT:
There is disclosed apparatus for implementing a technique of shingling a stack (10) of cut sheets using fluid jets. Air (34), or other fluid under pressure, travels through a drum having exit holes arranged about its periphery. The passage of the air causes the drum (30) to self-propel. As each fluid jet contacts the uppermost sheets in the stack, a roll-wave is created. Continued rotation of the drum causes a fluid jet to describe a linear path relative to the stack surface.
