The invention relates to a method and to a device for banding a stack of products which are to be stacked (52). A band (22) is unwound from a store roll of a band machine (10) and a loop (62) is formed for the stack of products which is to be stacked (52), by means of a band insertion/withdrawa l unit (39). After the free end of the band is fixed in a return device and th e band (22) is pulled to the stack of products which is to be stacked, the fre e end is stuck or welded and the pulled loop (62) is cut. In a program- controlled, continuous process and prior to changing the band, the end of th e band (22) of a first band roll (18) is detected and the remainder of the ban d (22) is retracted. Then, the band (22) threaded into the band store (25) of a second complete band roll (20) is inserted into the band insertion/withdrawa l unit (39) and the band continuos with delay. The end of the totally automati c band exchange is optically and/or acoustically displayed and the roll can change without pressure.
