ABSTRACT:
The invention teaches a sensing device arrangement for a tissue paper roll to give advance warning when the material forming the roll approaches the end. The present invention uses a sensing arrangement which comprises a bracket, a tissue paper roll retaining member, a means for detecting the end of the tissue roll and a signalling means for indicating the end of the tissue roll. The signalling means is operably connected to and activated by the detecting means, when there is a small amount of paper left on the roll, indicating to an attendant that it is necessary to change the paper roll.
