Abstract (en)
[origin: WO2011059423A1] Apparatus, systems and methods for dispensing sheet material (12) from a roll (11) which include a low-material sensing system. The low-material sensing system provides an indication when the sheet material (12) approaches depletion or is depleted so that the depleted sheet material roll (11) can be replaced with a full roll. The low-material sensing system determines that the sheet material (12) is depleted or near depletion by comparing the rotational speed of a sheet material roll (11) from which the sheet material (12) is unwound with the speed of the motor (21) which produces movement of the sheet material roll (12) when power is supplied to the motor (21). The sheet material roll (11) speed increases as material (12) is unwound while the motor (21) speed remains relatively constant. A low-material indication is provided when the comparison reaches a threshold representative of the low-material state.
