Abstract: An accessory for use with adding machines to receive paper tape and the like from an adding machine as printed-out on one side and to reverse the tape, rewinding its unused-side out ready for re-insertion as a fresh roll in the adding machine so that both sides of the tape can be used, making a 100% saving in the cost and quantity of the paper stock used, at a modest outlay for the device of this invention; a pedestal mounted, slot-held, disassemblable manually-operated reel with co-acting superposed guides has a friction plate for maintaining tape tension and guide plates spaced beneath the guides a distance preventing accidental disassembly.
