    • The improved rotary cutter performs cutting by making a knife edge portion of a rotating disc-shaped knife (2) bite into a surface of a sheet (1) being successively fed. On the underside of the traveling sheet (1), a brush (4) consisting of rod-shaped brush elements is fixed on a backing table (3) between point A and point B over the entire region in the lateral widthwise direction of the sheet (1), a knife edge of the knife (2) is disposed close to a front end portion of the backing table (3), upon transfer of the knife in the lateral widthwise direction of the sheet the knife is raised to be disengaged from the brush and the sheet and then it is transferred and set in position. Thereafter, while the knife is being rotated, it is lowered to be engaged with the sheet and again cuts the sheet. In addition, paper powder produced as a result of cutting a sheet is removed by providing a suction box (16) extending over the entire region of the maximum lateral width of the sheet right under the disc-shaped knife (2). Furthermore, grindstones (26,27 and 29) for grinding the knife edge of the disc-shaped knife are provided so as to be movable in the axial direction of a shaft (11) of the disc-shaped knife (2), and in addition, there is provided a felt (34) immersed in soapy water for peeling off paste from the knife (2).
    • 改进的旋转切割机通过使旋转的盘形刀(2)的刀刃部分咬入到连续进给的片材(1)的表面中来进行切割。 在移动片(1)的下侧,由片状刷元件组成的刷子(4)在片材的横向宽度方向上的整个区域上固定在点A和点B之间的背衬台(3)上 (1)中,刀片(2)的刀刃设置在背板(3)的前端部附近,当刀沿刀片的横向宽度方向转动时,刀被升高以脱离 刷子和纸张,然后将其转移并设置就位。 此后,当刀被旋转时,其被降低以与片材接合并且再次切割片材。 此外,通过在盘形刀(2)的右下方的片材的最大横向宽度的整个区域上设置吸引箱(16)来除去由于切割片材而产生的纸粉末。 此外,用于研磨盘形刀的刀刃的磨石(26,27和29)设置成可在盘形刀(2)的轴(11)的轴向上移动,并且 此外,提供了浸在肥皂水中的用于从刀(2)剥离浆料的毡(34)。
