ABSTRACT:
There is provided an apparatus for supplying precisely measured lengths of leader ribbon for use in the assembly of printer ribbon cartridges. The apparatus includes a supply of leader ribbon, an accumulator for retaining a length of the ribbon when it is drawn from the ribbon supply and a drive assembly for drawing a measured length into the accumulator. The drive assembly includes a fixed roller and a pivotable roller positioned on opposite sides of the ribbon path for engaging the ribbon therebetween. A stepping motor is provided for rotating the rollers a prescribed number of revolutions and thereby stuffing a measured length of the engaged ribbon into the accumulator. The apparatus also includes a cutter for severing the measured leader length from the supply ribbon.
