    • An apparatus for perforating a length of pierceable material which includes a first roller, the length of pierceable material being in engagement with and at least partially circumscribing said first roller; and a second roller disposed in close proximity to the first roller. The second roller, which is provided with a plurality of piercing members, is movable from a first position wherein the piercing members are spaced apart from the first roller to a second position wherein selected ones of the piercing members pierce the length of pierceable material. Uniquely, the first roller has a plurality of transversely spaced grooves that receive the extremities of the piercing members when the first roller is in the second position.
    • 一种用于穿孔一段可刺穿材料的装置,包括第一辊,所述可刺破材料的长度与所述第一辊啮合并且至少部分地围绕所述第一辊; 以及设置在第二辊附近的第二辊。 设置有多个穿刺构件的第二辊可从第一位置移动,其中穿刺构件与第一辊间隔开至第二位置,其中穿孔构件中的选定穿孔构件刺穿可刺穿材料的长度。 唯一地,当第一辊处于第二位置时,第一辊具有多个横向隔开的凹槽,其容纳穿孔构件的末端。
