    • The invention relates to an apparatus (1) for unwinding a material web (2), which is wound up onto a core (3), the apparatus comprising a conveyor unit (5) arranged to pull the unwound material web (2) along a conveyance path, wherein the conveyor unit includes a first roller (7) and a second roller (8) extending substantially across a width of the material web and sandwiching the material web in-between, wherein the first and second rollers are configured to frictionally engage the material web (2) in a longitudinal and lateral direction, wherein at least one of the first and second rollers is provided with at least one cutting disc (10) arranged to penetrate the material web so that the material web is slitted into strips.
      As the cutting discs are attached to one of the rollers in the conveyor unit the number of components and the number of cutting discs can be reduced, thereby reducing the complexity and cost of the equipment for unwinding and slitting the material web.
    • 本发明涉及一种用于展开材料卷材(2)的装置(1),该材料卷材卷绕在芯部(3)上,该装置包括一个输送单元(5),该输送单元布置成沿着一个 输送路径,其中所述输送单元包括基本上横跨所述材料幅材的宽度延伸并且将所述材料纤维网夹在其间的第一辊(7)和第二辊(8),其中所述第一和第二辊构造成摩擦接合 所述材料幅材(2)在纵向和横向方向上,其中所述第一和第二辊中的至少一个设置有至少一个切割盘(10),所述切割盘布置成穿透所述材料幅材,使得所述材料幅材被切成条带。 当切割盘连接到输送机单元中的一个辊时,可以减少部件的数量和切割盘的数量,从而降低用于展开和切割材料网的设备的复杂性和成本。
