Banding machine for packaging logs of stacks of folded, overlapped or interfolded sheets applies a banding web of paper or plastic film on four longitudinal sides. During motion of the web in a direction orthogonal to the drawings, a glue gun spreads a glue line the length of the web, near the lower free wing. The packaging web crosses the walls at upper and lower gaps. Pushing the compressed log in the channel, the packaging web is arranged stretched in front of the log, the log being pushed against the packaging web well beyond the gap, causing self-packaging, i.e. the log is wound for ¾ by the web, leaving two free wings with the second having glue on it. At least one of the sections includes a movable portion, which can be a rotating wall, for enlarging the gap to allow the movement of the glued zone of the web.
