    • The application relates to a device for quickly and precisely aligning and fixing foil blades on the body part of a blade roll. The rotary blade roll has a rotating shaft, at least one roll body part arranged with torsional strength on the rotating shaft, at least one foil blade supported by the roll body part, and a row of holding and positioning pins in the roll body part. Magnetic elements arranged in rows retain the foil blade flatly on the peripheral surface of the roll body part. The foil blade has a thin flexible magnetically permeable base plate and at least one sharp one-piece cutting edge of a predetermined cutting shape projecting from the base plate. The base plate has a leading edge, a trailing edge, two side edges opposing each other, and, in a front zone adjoining the leading edge, a plurality of slots aligned with the cutting edge. The holding and positioning pins radially project from the peripheral surface with a height (h) approximately corresponding to the base plate and project into the slots. The width (b1) of the thickness (d1) pins corresponds with the slot width (b) so that the foil blade can be axially displaced and repositioned within the range of the slot length (d5) while being fixed and reproducibly positioned peripherally to the roll body part.
    • 本申请涉及一种用于在刀片卷的主体部分上快速且精确地对准和固定箔片的装置。 旋转叶片辊具有旋转轴,在旋转轴上具有扭转强度的至少一个辊体部,由辊主体部支撑的至少一个箔片叶片和在辊体部分中的一排保持定位销。 排成行的磁性元件将箔片平坦地保持在辊体部分的周面上。 箔片具有薄的柔性导磁基板和从底板突出的至少一个具有预定切割形状的至少一个尖锐的一体式切割刃。 基板具有前缘,后缘,彼此相对的两个侧边缘,并且在与前缘相邻的前部区域中具有与切削刃对准的多个槽。 保持定位销从圆周表面径向突出,高度(h)大致对应于基板并突出到槽中。 厚度(d1)引脚的宽度(b1)对应于槽宽度(b),使得箔片刀片可以在狭槽长度(d5)的范围内轴向移位和重新定位,同时被固定并可重复地定位在外围 卷体部分。
