Abstract
A dispensing device for sequentially dispensing sheet material such as paper toweling from a primary roll and a reserve roll, the primary roll initially being rotatably mounted at a first location and adapted to be displaced therefrom to a second location. Sheet material feed means is provided for dispensing the sheet material from the device. Sensing means is provided for sensing displacement of the primary roll from the first location and transfer means is employed in operative association with the sensing means and responsive to the sensing of the displacement of the primary roll from the first location to place sheet material from the reserve roll into operative engagement with the sheet material feed means. The transfer means includes metering means for metering sheet material removed from the primary roll by the feed means after displacement thereof has been sensed by the sensing means, said transfer means being responsive to the metering of a length of sheet material having been removed from the primary roll before placing the sheet material from the reserve roll into operative communication with the sheet material feed means.
