  • the control unit of the dispenser is adapted to activate the second transport arrangement upon detection of a user change by the detection arrangement.
  • an activation of the second transport arrangement results in the at least partial retraction of the tissue portion protruding through the dispensing opening back into the housing of the dispenser, in particular by coiling the used tissue on a used tissue roll by the second transport arrangement.
  • the solution as described herein is based on the finding that existing dispensers and methods for providing portions of tissue have drawbacks in particular in high-frequency operating situations.
  • High-frequency operating situations typically are situations where a high number of users intends to use the dispenser in quick succession.
  • Existing dispensers, in particular retracting dispensers may not be adapted for such a high-frequency use.
  • the retrieving of used tissue by a second transport arrangement may be too slow or too delayed for such a quick succession of uses.
  • retracting dispensers the retrieval of used tissue by the second transport mechanism takes place after a certain time after unused tissue has been provided to the dispensing opening.
  • the reason for this delay of the retrieval of the used tissue portion is to give a user sufficient time to use the portion of tissue protruding through the dispensing opening.
  • the use of this tissue portion typically takes place by a user grabbing the tissue portion and moving it over his hands for drying hands.
  • a retrieval of used tissue by the second transport arrangement directly after provision of the tissue portion by the first transport arrangement would result in the user not having a large enough portion protruding from the dispensing opening for actually accessing this tissue portion and using it for drying the hands.
  • the solution as described herein is based on the finding that such drawbacks can be avoided when the second transport arrangement is activated as soon as the person using the dispenser changes.
  • the solution as described herein provides for a detection arrangement for detecting a user change and a control unit for activating the second transport arrangement upon such detection.
  • the solution described herein detects such a user change and activates the second transport arrangement. This has the advantage that as soon as a user change occurs, the retrieval of the used portion can be initiated. In this way, it can be avoided that two or even more times an unused tissue portion is provided through the dispensing opening before a used tissue portion is retrieved. Increasingly large loops, and even floor loops, can be avoided in this way.
  • the control unit preferably is connected to various components of the dispenser using a wired or wireless connection in order to transfer signals, e.g. sensor signals, activation signals, deactivation signals, control signals and the like, and to generate and/or process and/or receive and/or transmits such signals.

  • control unit is adapted to activate the first transport arrangement when a user change is detected.
  • the event of a user change can also trigger the activation of the first transport arrangement, which preferably results in dispensing a further unused portion of tissue web through the dispensing opening.
  • the new user does not need to activate, for example manually or via an automatic, e.g. non-touch, activation mechanism, the provision of a new portion of tissue web. Rather, by activating the first transport arrangement upon detection of a user change, the new user will be provided with an unused tissue portion without the need for further action from his or her side.

  • step 406 it is determined whether the user moves away from the sensor. This is done as long as the user does not move away. As soon as the user does move away, the release element is activated in step 407 and the blocking element 210 is released. Subsequently, in step 408, the detection arrangement goes back into energy-saving sleeping mode.
