Abstract
In a method of feeding wrapper material, typically as utilized by machines for the manufacture of tobacco products, a first and a second strip presenting two longitudinal side edges and of dissimilar transverse dimensions are advanced along respective predetermined first feed lines, positioned one relative to another in a direction transverse to the respective first feed lines in such a way as to bring about their alignment along one longitudinal edge and finally joined face to face before advancing together along a predetermined common feed line toward a machine unit.

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.
