Abstract
Device for handling cardboard reels, comprising a main body (8) with a rod (45) on which are arranged: a first unit with two axially opposed plates (91, 92), provided with respective radially expandable parts (913, 923), and spaced apart by a predetermined value along an axial direction (A9) of said rod (45) so as to forming a pressurizable space (S) between said plates, said space (S) being delimited at the top and bottom by opposite surfaces (912, 922) of said plates (91, 92); means for controlling the radial expansion of said parts (913, 923); pressurization means for pressurizing said space (S).

Device for handling cardboard reels, characterized in that it includes a main body (8) with a rod (45) on which are arranged:
- a first unit with two axially opposed plates (91, 92), provided with respective radially expandable parts (913, 923), and spaced apart by a predetermined value along an axial direction (A9) of said rod (45) so to form a pressurizable space (S) between said plates, said space (S) being delimited above and below by opposite surfaces (912, 922) of the same plates (91, 92);
- means for controlling the radial expansion of said parts (913, 923);
- pressurization means for pressurizing said space (S).
Method for handling cardboard reels, comprising a step of preparing a stack (2) of cardboard reels (1) in a parking point (P) of a site for the production of cardboard tubes comprising at least one tube-forming machine (3) and a corresponding unwinder (30) by means of which the tube-forming machine (3) receives a cardboard strip unwound from a reel (1) positioned on the unwinder (30), each reel (1) having a central tubular core (1C), characterized in that it includes the following further operational phases:
- inserting, in the central tubular core (1C) of the top reel of the stack (2), two plates (91, 92) spaced apart by a predetermined value (k) along a predetermined axial direction (A9) and provided with respective radially expandable parts (913, 923), forming a pressurizable space (S) at the interface between said reel and the underlying reel of the stack (2), said pressurizable space (S) being formed by opposing surfaces (912, 922) of said plates;
- pressurizing said space (S) so as to determine the detachment of said reel from the underlying reel.
