<p>Two rolls(1,2) rotate in opposing directions with a gap between them. A restraining bar(10) for holding back containers or sacks of containers is located above the feed and compression zone of the rolls. Perforation tools(9) are spaced along the rolls. The restraining bar(10) comprises either a round or rectangular hollow profile, a shaped hollow member or a solid bar. Spacing of the restraining bar and rolls can be adjusted either in steps or smoothly. Strippers located in the ejection area of the rolls separate interlocked, deformed and perforated containers.</p> |
