1. A device for removing adhesive labels or the like from a substrate comprising:

  • a reel on which said substrate is wound;

    means for mounting said reel for rotation about an axis of rotation;

    a housing having a trough in which said reel is mounted with an open upper end, said housing including a horizontal guide having a horizontal surface for supporting said substrate situated at a level higher than said axis of rotation, and a bending edge for the substrate at the end of said guide surface remote from said trough;

    a light source disposed adjacent said bending edge;

    driving means located below said guide surface for engaging said substrate to pull said substrate past said edge so as to separate one at a time said labels from said substrate;

    a photo-electric cell disposed adjacent said bending edge for producing a given electrical signal indicating the presence of a separated label, when said label is located between said source and said cell; and

    circuit means connected to said photo-electric cell for disabling said driving means when said given signal is produced.
