A web unwind stand for obtaining, loading, splicing, and unwinding a web material from a plurality of convolutely wound rolls and forwarding the web material unwound from each of the convolutely wound rolls uninterruptedly to a downstream apparatus is disclosed. The unwind stand has a frame, a positionable roll grasping apparatus having a mandrel connectively engaged thereto and, splicing means. The positionable roll grasping apparatus is capable of obtaining and disposing the convolutely wound rolls proximate to the splicing means relative to the frame.

A process for improving the convertability of parent rolls of convolutely wound web materials is disclosed.

An apparatus for the non-compression transportation of a convolutely wound web material parent roll is disclosed. The apparatus comprises a motivator and an end effector operably, cooperatively, and pivotably engaged to the motivator. The end effector provides a pair of opposed core plugs capable of cooperative and penetrating engagement with a core of the parent roll when the first core plug is disposed proximate to a first portion of the core of the parent roll and the second core plug is disposed proximate to a second portion of the core of the parent roll disposed distal therefrom.

Various embodiments of the present disclosure provide a coil-wrapping system (30) that simultaneously employs separate multiple film rolls (FR1, FR2) to simultaneously wrap separate films around a single coil while the coil is rotated about its longitudinal axis.

System for handling cardboard reels to feed machines that produce cardboard tubes, comprising a station (F) for picking up the reels configured to receive a stack (2) of overlapping cardboard reels (1), a station (U) for unwinding of the reels, and handling means (D) for moving the reels (1) along a predetermined path. The means (D) for moving the reels comprise pneumatic means intended to pressurize a space (S) inside the stack of reels, in which said space includes the interface between an uppermost reel of the stack and the underlying reel, and gripping means configured and controlled to perform grip and release of the highest reel in the stack respectively.

A method and apparatus for the production of coreless paper rolls, including a winding phase on a central spindle of a paper web carried out by a main reel, until the formation of a wound paper roll, a phase of extraction from the wound roll of the spindle by application of a relative axial extraction force between the roll and the spindle, where the winding phase includes a first winding phase of a number of web revolutions on the central spindle performed at a first winding tension that is lower than the next winding tension.

The line for producing tubes made of web-like material, includes a core winder, an unwinder including a rotary device on which there are arranged a first spindle and a second spindle; and a robot adapted to load reels of web-like material onto the unwinder and remove exhausted reels from the unwinder.

System for handling cardboard reels to feed machines that produce cardboard tubes, comprising a station (P) for picking up the superimposed cardboard reels (1), a reel unwinding station (1) comprising at least one unwinding unit (UU) capable of supporting the reels to be unwound, in the unwinding station (U) being also provided splicing means configured to splice a tail portion (TY) of a reel (1 Y) being exhausted with a new reel (1W), and handling means (D) for moving the reels (1) along a predetermined path between the reel pick-up station (P) and the unwinding station (U). Said at least one unwinding unit (UU) comprises several supports (403; 404) mounted on a vertical axis carousel structure (G).

Various embodiments of the present disclosure provide a coil-wrapping system (30) that simultaneously employs separate multiple film rolls (FR1, FR2) to simultaneously wrap separate films around a single coil while the coil is rotated about its longitudinal axis.
