Abstract: A system for keeping a dispensing apparatus for a zigzag folded web of towel material optimally filled, which system is provided with a holder included in a housing for receiving a stock of zigzag folded web of towel material, which, on the one side, runs from the holder to a space of use and, on the other side, has an end that is connectable with a first free end of a correspondingly zigzag folded web of towel material forming a refill stock. The holder is provided with a fill meter with, in thickness direction of the stock of zigzag folded web of towel material, a division into at least three areas each having its own coding, with a first upper coding in said thickness direction indicating that no refilling is required, a second coding following the first indicating refilling with a refill stock provided with a coding equal to the second coding and each further coding indicating refilling with an increasingly thicker refill stock with corresponding coding.
