ABSTRACT:
A label dispenser for automatically applying butt cut labels from a dispensing roll onto workpieces positioned on a conveyor system. A web with adhered edge to edge labels in coiled form is rotatably supported above the conveyor and caused to unwind by pinch rollers. Unwound portions of t he web are caused to wrap around a circumferential portion of a roller, thereby accentuating gaps created by the cut lines. A sensor detects the accentuated cut line between adjacent labels and generates an electrical signal responsive to times when a cut is detected. The signal controls the operation of the drive roller such that a single label is applied to an article on the conveyor system.
