ABSTRACT:
In a packaging machine supplied continuously with strip material fed forward by means of pinch rolls and trimmed at a cutting station, the leading end of a new strip is overlapped with the trailing end of the depleted strip at the moment of effecting a changeover; the two strips are separated, before entering the cut, by a device comprising a pair of feelers stationed between the pinch rolls and the cutting station, and capable of movement at least between an at-rest position in which the feelers remain outside the dimensional compass of the strip material, and an operating position in which the feelers are moved substantially into alignment with the leading end of the new strip in such a way as to slip beneath and detach it from the trailing end of the depleted strip.
