摘要： A sensing arrangement for indicating the depletion of a coreless roll of absorbent paper web material in a dispenser, the sensing arrangement includes a roll support for supporting an inner circumference of the coreless roll, the roll support extending along a longitudinal center axis, the roll support comprising at least one roll expanding portion extending over a part of the roll support length and having a maximum radial extension defining a first radius from the center axis, and at least one sensing portion, extending longitudinally over another part of the roll support length and having a maximum radial extension defining a second radius from the center axis, wherein the first radius is greater than the second radius by a sensing offset length, and a sensing element arranged to sense at the sensing portion the amount of web material remaining on the roll when arranged over the roll support length.
