Method for spatially arranging coils, the method comprising: providing electronic data about an initial storage state, which electronic data contains information about a respective initial diameter of the coils and a respective initial spatial storage position of the coils in a coil store; transporting a selected coil from an initial storage position to a processing machine for processing at least a portion of the sheet metal of the selected coil; sensing a reduced diameter of the selected coil after the portion of the sheet metal has been removed from the selected coil for processing by the processing machine; storing the reduced diameter of the selected coil; transporting the selected coil having the reduced diameter to a depositing storage position which, depending on the reduced diameter, is selected to differ from the initial storage position in a manner that saves storage space; and storing the depositing storage position.

Support pin for supporting reels of paper material, comprising an outer side (PX) and an inner side (PN), with the inner side (PN) that is adapted to be inserted into a reel (1) of paper material and with the outer side (PX) that remains on the outside of the same reel (1) when the inner side (PN) is inside the reel (1), said outer side (PX) being provided with a hooking portion (3) adapted to be engaged by means (CP) adapted to vertically move the pin (P). The outer side (PX) of the pin (P) is constituted by a shank (2) whose longitudinal axis coincides with the longitudinal axis (x-x) of the pin (P) and said hooking portion comprises an eyelet formed on the shank (2) and delimited by two parallel arms (30) that emerge radially from the shank (2) and are joined by a body (31) parallel to said longitudinal axis (x-x).

Device for handling paper reels, comprising a bridge crane (CP) with movable arms (BC) each of which is adapted to engage a pin (P) insertable into a corresponding side of a reel (1) and a platform (PB) adapted for supporting the reel (1). The device further comprises detection means adapted to detect load variations on said arms (BC) during insertion of the pins (P) inside the reel (1), and moving means adapted to achieve a relative movement between the reel (1) and the arms (BC) when the absolute value of a variation of the load detected by said detection means exceeds a predetermined limit up to bring said value below the predetermined limit.

Method for the handling of parent reels in paper converting plants, comprising the following steps: (a) providing at least one platform with a base adapted to support a parent reel in a waiting station and at least one unwinder (S) adapted to receive said reel in an unwinding station where the parent reel is unwound; (b) positioning a parent reel (1) on the platform at the waiting station; (c) transporting the parent reel (1) along a predefined path from said platform to said unwinder (S) by means of a bridge crane (CP) equipped with movable arms (BC). The step (c) is preceded by a first step consisting in the temporary association of two pins (P) to the arms (BC) of the bridge crane (CP) and by a second step consisting in inserting the two pins (P) in two opposite bases of the parent reel (1) using the same arms (BC); and the step (c) involves the transport of the reel (1) along a path comprising at least one ascending or descending portion with the pins (P) thus inserted into the parent reel (1).

The unwinder includes an unwinding station, in which to arrange a reel to be unwound. In the unwinding station there is arranged a series of guide rollers, defining a feed path of the web material. There are also provided: a cutting member adapted to cut a web material coming from an exhausted reel, and splicing members, to splice a trailing edge of a first web material coming from an exhausted reel to a leading edge of a second web material coming from a new reel. A pick-up device is configured to pick up the leading edge of the second web material from a temporary retaining element, carried by a transfer unit to transfer reels to the unwinding station.
