1. A unit for control or management of paper rolls in a plant having an operating line with multiple sections for making and packaging the paper rolls; the unit comprising:
a conveying section for conveying the paper rolls, the conveying section including:
a first conveying device, a second conveying device, and a drop zone positioned between the first conveying device and the second conveying device, with the first conveying device being positioned upstream of the drop zone and the second conveying device being positioned downstream of the drop zone,
wherein at least the second conveying device has a movable end movable longitudinally or telescopically, relative to a fixed portion of the first conveying device, between an advanced position supporting and conveying the paper rolls and a retracted position allowing the paper rolls to drop in the drop zone,
wherein the movable end is positioned high enough above a bottom surface of the drop zone to allow the movable end to return to the advanced position while one of the paper rolls is underneath in the drop zone;
an electronic process controller configured for controlling functioning of the sections;
a detection device for detecting a defective paper roll; and
an eliminating device for eliminating the defective paper roll, the eliminating device including the movable end;
wherein the electronic process controller is configured to determine one or more of:
a diameter of the roll by determining a distance between transverse or lateral edges of the roll;
a length of the roll by determining a distance between longitudinal end edges or between transverse end faces of the roll; or
a presence of an oblique transverse face by determining a distance between longitudinal end edges of the roll at two different transverse positions or at two respective, longitudinal lines which are transversely spaced from each other.
