发明名称 Non-woven fabric perforating device and method therefor
摘要 The present invention relates to a perforation apparatus (1) for nonwovens, with a perforating roll (4) and an opposing roll (5). The perforating roll (4) and opposing roll (5) form a gap (9), through which a nonwoven (6) being perforated, is guided and perforated. The perforation apparatus (1) comprises a feed device (8) and a withdrawal device (12). The feed device (8) is arranged such that the nonwoven (6) being perforated advances first onto the opposing roll (5), before it enters the gap (9). The withdrawal device (12) is arranged such that after leaving the gap (9), the perforated nonwoven (10) remains on the perforating roll (4). Furthermore, a perforation method and a corresponding nonwoven structure are provided.
