Abstract:
A method of feeding wrapper material in manufacturing machines, comprising:advancing at least a first and a second strip of wrapper material alone respective first and second feed lines, each strip presenting two longitudinal side edges and one strip exhibiting a transverse dimension greater than the transverse dimension of the other strip;positioning the first and the second strip mutually along a direction transverse to the respective first and second feed lines;joining the first and second strips together face to face and advancing both along a common feed line toward a machine unit;decoiling each strip initially from a respective roll;dividing each of the first and second strips longitudinally by respective cutters to generate a first pair of first strips and a second pair of second strips;causing each of the two first strips and each of the two second strips to spread apart transversely one from another and to advance thereafter along respective second feed lines;positioning each first strip of the first pair and each second strip of the second pair relative to one another in overlapping relation, in sets of two, along a direction transverse to the respective pre-determined second feed line;joining each first strip of the first pair face to face with a corresponding second strip of the second pair and advancing both together along a respective predetermined common feed line.
