ABSTRACT:
A rotating inverter mechanism includes a drive shaft and dual primary and secondary rollers mounted within a set of collars such that the drive shaft is adapted to provide rotation to the primary rollers in a clockwise direction while the secondary rollers which are initially in an out of sheet contact position are driven by the primary rollers in a counterclockwise direction. A sheet passing through the inverter in a clockwise direction actuates a first sensor which in turn actuates a solenoid linked to one of the collars. The solenoid pulls the collar through a predetermined angle and thereby places the corresponding secondary roller in contact with the sheet. Since the secondary roller is rotating in a direction opposite to the incoming sheet direction and opposite to the other primary roller, the sheet will be rotated. A chute is positioned to deflect the sheet downward as it is rotated so that the rotation can be accomplished in a distance no wider than the width of the sheet. The sheet will continue rotation until it actuates a second sensor which in turn actuates another solenoid linked to the other collar and thereby places the other secondary roller in contact with the sheet. The sheet is then driven out of the inverter in a second direction. After the sheet has left the influence of the primary and secondary rollers, it passes a third sensor which sends a signal that deactuates the solenoids and thereby allows the primary rollers to assume their original sheet contact position for feeding a sheet in the clockwise direction.
