Method for handling parent reels in paper converting plants

A method for handling parent reels in paper converting plants, the method comprising the following steps:

• providing at least one platform with a base configured to support a parent reel in a waiting station and at least one unwinder configured to receive said parent reel in an unwinding station where said parent reel is unwound;
• positioning said parent reel on said platform at said waiting station;
• providing a bridge crane comprising movable arms;
• moving a plurality of pins relative to said parent reel via said movable arms such that one of said plurality of pins is inserted in one base of said parent reel and another one of said pins is inserted in another base of said parent reel via said movable arms;
• and
• transporting said parent reel along a predefined path from said platform to said at least one unwinder via said bridge crane after inserting said plurality of pins in said parent reel, wherein one of said movable arms is in contact with said one of said plurality of pins and another one of said movable arms in contact with said another one of said plurality of pins when said parent reel is transported along at least a portion of said predefined path via said bridge crane, said transporting said parent reel along said predefined path comprising at least one ascending or descending portion with said two pins inserted into said parent reel, wherein each of said movable arms is moved to a position located at a spaced location from said two pins after said parent reel is transported along said predefined path.
