摘要

A first unwinding device (1) unwinds a first roll of a first length of flat cardboard and has two pairs of arms (5A,5B) for holding a roll (BA1) in a working position and a roll (BA2) in a waiting position. A first length (N1) of board is prepared continuously thanks to the presence of a splicing device, which joins the end of a length coming off the roll in a working position with the start of a length coming off the roll in a waiting position.
