A rewinding machine is described with a winding cradle defined by three rollers and including a fourth winding roller defining with the first winding roller a cradle in which the web material is pushed by a winding core to the beginning of each winding cycle, to cause severing of the web material without the need for controlled mechanical parts.

A method, and a module (1) for its implementation, is provided for unwinding and splicing reels (2) of flexible material articles. The method includes unwinding a full reel (2) from an unwinding station (4), the reel being positioned on a rotating assembly (3); and, during the unwinding of the reel, positioning a new full reel (2) from a reloading station (5) onto the rotating assembly (3). When the unwound reel is empty, the method includes rotating the rotating assembly (3) to move the empty reel to the reloading station (5) and, simultaneously, the full reel to the unwinding station (4) The method includes splicing the initial end of the article from the full reel with the final end of the article from the empty reel, and unwind the full reel from the unwinding station (4); and From the reloading station (5), removing the empty reel and position a new full reel. The process from step C) may be repeated as many times as necessary.

A reel attaching/detaching device that attaches/detaches a reel on which a tape accommodating a component is wound to and from a feeder which feeds out the tape by a drive of a feed-out section and supplies the component, the device includes a feeder set unit configured to be set in a predetermined orientation when the feeder supplies the component, a reel set unit configured to be set in a predetermined orientation when the reel supplies the component, a transfer robot configured to transfer the reel between the feeder set unit and the reel set unit while holding a orientation of the reel, and a control device configured to control the transfer robot so that the reel is detached from the reel set unit and the reel is attached to the feeder set in the feeder set unit, when the reel is set in the reel set unit.
