ABSTRACT:
An improved disc-shaped knife rotary cutter which has a reduced size and is not complicated in structure as a whole, and which require a knife only on the upper side of a traveling sheet. The knife can be used over a long period and paper powder produced as a result of cutting of a sheet by the knife can be removed by a suction box extending over a full width of the sheet. The improved rotary cutter performs cutting by moving a knife edge portion of a rotating disc-shaped knife into a surface of a sheet being successively fed. On the underside of the traveling sheet, a brush consisting of rod-shaped brush elements is fixed on a backing table over the entire region in the lateral widthwise direction of the sheet. A knife edge of the knife is disposed close to a front end portion of the backing table and 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. Furthermore, grindstones for grinding the knife edge of the disc-shaped knife are provided so as to be movable in the axial direction of a shaft of the disc-shaped knife, and in addition, there is provided a felt immersed in soapy water for peeling off paste from the knife.
