Abstract
A roll of web-shaped material with a hollow roll core on which the web-shaped material is wound includes a signal-generating arrangement for generating an acoustical signal when the roll is rotated on a shaft as the web-shaped material is unwound therefrom and the signal-generating arrangement is part of the roll core.
Claims18
A roll of web-shaped material comprising a hollow roll core having a web-shaped material wound thereon, said core having a signal-generating means for generating an acoustical signal, which is triggered when the roll is seated on a shaft of a dispenser and the web-shaped material is unwound, said signal-generating means being integrated in the roll core.
A device for unrolling a web-shaped material with a stationary acceptance shaft for holding a roll of web-shaped material, said roll having a roll core receiving the material and a signal-generating means for generating an acoustical signal being associated with the core so that movement of the core on said shaft causes a signal to be emitted from said signal-generating means.
