ABSTRACT:
An indexing device includes a layer of film and pressure sensitive adhesive material located on at least a portion of one side of the layer of film to enable the layer of film to adhere to an object such as a finger. The indexing device further includes material having a very high coefficient of friction with respect to the objects to be indexed disposed upon at least a portion of the second side of the film layer. By sliding the material disposed on the second side of the indexing device across a planar object such as a sheet of paper, a substantial frictional force is developed that resists the relative movement of the indexing device and the planar object. This resistance to relative movement serves to index or separate the planar object from adjacent planar objects.
