A transport system for conveying sheet material along a feed path. The transport system includes an electro-dynamic propulsion system for moving sheet material, or a stacked collation of sheet material, along a support deck which defines the feed path. More specifically, the electro-dynamic propulsion system includes at least one guideway and a ferromagnetic element disposed internally of the guideway. The guideway includes a magnetic coil to produce a variable magnetic field. By varying the flux density and polarity of the magnetic field the ferromagnetic element may be propelled within the guideway. An abutment member is coupled to the ferromagnetic element, extends through the elongate opening of the support deck and engages an edge of sheet material. A processor is operative to control the electro-dynamic propulsion system and, accordingly, the rate of travel and position of the sheet material along the feed path.
