Abstract
A re-registering feeder machine which is also an improvement to a separating machine accepts sheets of paperboard or other material with various angles of skew, registers them and feeds them to a following machine. A conveyor deck moves the sheet in a first direction where at the last roll the sheet is held down by a plurality of balls in cooperative rotation with the last roll and its leading edge meets a side register guide having a plurality of pairs of tapered drive rolls to grip the sheet along the margin and move the sheet in a second direction at right angles to the first direction after the sheet has been registered. Coatings on the conveyor rolls except for the last roll which has the cooperatively rotating balls in contact therewith provide a proper friction between the rolls and the sheet allowing the sheet to turn in either direction until the angle between its leading edge and the side register guide is zero. The side register guide then operates in coordination with a pair of stops and a force transducer to provide a final registration to a preselected sheet leading edge and corner thereof.
