Claim 0:
1. A sensing arrangement for indicating the depletion of a coreless roll of absorbent paper web material in a dispenser, the sensing arrangement comprising:
a roll support configured to be inserted into an inner circumference of said coreless roll with said roll extending over a roll support length so as to support said coreless roll, said roll support extending along a longitudinal center axis,
the roll support comprising:
at least one roll expanding portion extending over a part of said roll support length and having a maximum radial extension defining a first radius from said center axis, and
at least one sensing portion, extending longitudinally over another part of said roll support length and having a maximum radial extension defining a second radius from said center axis,
wherein said first radius is greater than said second radius by a sensing offset length, and
a sensing element configured to sense that the web material remaining on the roll is depleted when a distance between the sensing element and the sensing portion becomes less than the first radius,
wherein said sensing element is a mechanical sensing element that is pivotably arranged so as to be pivoted towards said sensing portion of said roll support.
