To provide a method of feeding wrapping material in a product packaging machine such as be unaffected by the drawbacks, which derive from the enforced positioning of a relatively bulky cutting device in close proximity to the wrapping line of the machine.
Wrapping material is supplied to the folding position of a packaging machine, such as a cigarette packer, by a method that includes a step of dividing a continuous strip 10 of multilayer material into single leaves 16, and a step of feeding the leaves 16 to a wrapping unit 6; the step of dividing the continuous strip into leaves combines a first stage in which a partial cut is made in the strip by means of a laser device 13, leaving at least one layer 21 of the multilayer strip intact, and a second stage in which a single leaf 16 is detached by means of a tear device 15, separating along a score line 22 created by the partial cutting step.
