ABSTRACT:
There is provided an apparatus for allowing a paper tape to be unwound from a first roll by a printing unit, and for simultaneously rewinding the paper tape on a second roll. Each roll includes a hollow cylindrical core. The apparatus includes a low friction cylindrical axle means for positioning within the hollow core of the second roll, and alignment means for maintaining the axle means such that its axis remains parallel with the axis of the second roll, and for keeping the two rolls laterally aligned. Retention means are also provided for keeping the two rolls together, the retention means preferably including an elastic cord member adapted to pass in a closed loop through the hollow core of the first roll and through a central opening in the axle means positioned in the hollow core of the second roll.
