Abstract
In an apparatus for transporting sheets along a travel path, a registration mechanism for aligning a sheet relative to the travel path. The registration mechanism comprises a support for a sheet moving along the travel path and a pair of frusto-conical rollers. The frusto-conical rollers are mounted for rotation about common axis, with the apex portions of the respective frusto-conical rollers oriented in the same direction relative to the common axis. The common axis is located to lie in a plane parallel to the plane of a sheet in the travel path and extend in a direction transverse to the direction of movement of a sheet along the travel path. The plane containing the axis is spaced from the sheet supporting means a distance such that the frusto-conical rollers are in nip relation with the sheet supporting means so as to urge a sheet in the travel path in the direction of movement along the travel path and in a direction transverse to the direction of movement with a minimum of skew induced in such sheet.
