An apparatus in which a sheet (102) is registered during the movement thereof. The sheet is moved along a path in a forward direction of movement and a lateral direction of movement substantially normal thereto by means of skewed driving and idler rollers (90, 76). The lateral movement of the sheet causes the side edge of the sheet to engage a registration edge (88) so as to be aligned thereat. The drive roller (90) extends into the gap between spaced idler rollers (76) to form a bend (106) in the sheet. The magnitude of the moving force applied on the sheet is proportional to the extent of the bending which in turn depends on the thickness of the sheet. In this way, the moving force varies as a function of the thickness of the sheet with the sheet slipping laterally when engaging the registration edge to prevent buckling thereof.
