Systems for processing material, taping stations to apply tape to one or more rolls of material, and methods of processing material are disclosed. A system for processing material includes a winding station and a taping station. The winding station includes a winder to wrap material around a mandrel to produce one or more rolls of material. The taping station is arranged downstream of the winding station to receive the one or more rolls of material therefrom and apply tape to the one or more rolls of material.

A reel unwinder including a first unwinding position, in which a first reel is positioned; a second unwinding position, to which the first reel is transferred when it is replaced with a second reel; a stand-by position, in which the second reel is kept in stand-by; a first unwinding member adapted to start rotation of the second reel when the first reel is replaced with the second reel. Moreover, the unwinder includes a second unwinding member, with at least one endless flexible element. The endless flexible element extends from the first unwinding position to the second unwinding position, and is adapted to maintain the first reel in contact with the second unwinding member and in rotation by the second unwinding member in the first unwinding position, in the second unwinding position and while it is being transferred from the first unwinding position to the second unwinding position.

A reel support assembly (14) for a web material processing machine is described. The reel support assembly (14) comprises a support frame (16) and at least a first support arm unit (34a) having at least one holding stub (40) for mounting a reel (12) on the first support arm unit (34a). Furthermore, the reel support assembly (14) comprises an elevator unit (24) having a support element (26) on which a reel (12) may be placed. The support element (26) is supported on the support frame (16) in a vertically movable manner. Additionally, a hotfoil stamping machine (10) is presented which comprises such a reel support assembly (14). The reel support assembly (14) is arranged at an upstream end of the hotfoil stamping machine (10) with respect to a web travelling direction.
