<p>The roller (5) has a rotating roller arranged at a distance to a counter-bearing by forming a gap. A cylindrical mantle surface includes multiple profiled partial regions (506) of a same type and a same width following one another in an axial direction in a working region. The partial regions are separated from one another by a circumferential recess (510). Each partial region includes multiple sections (507-509) following one another when axially viewed. A cam-shaped projection projects radially away from the mantle surface, and is provided in one of the sections. An independent claim is also included for a device for compaction of empty, disposable-hollow bodies.</p> |
