Embodiment Construction

[0042] figure 1 A projection of the knife according to the invention on a plane parallel to its disc 6 is shown. The teeth 1 , 2 are located on the circumference of the disc 6 . The disk cutter has an opening 7; in this case the opening 7 is drop-shaped, but the shape of the opening can also be different. The opening 7 joins the cutting edge 5 of the knife at said edge discontinuity 8 . Opposite the location 8 a further cutout 9 can be formed.

Description

technical field [0001] The object of the present invention is a rotary disc cutter, in particular a rotary disc cutter for cutting cigarette cartons. [0002] It is also an object of the present invention to provide a method of mounting a rotary disc cutter on the shaft of a cutting assembly and a method of removing a rotary disc cutter from the shaft of such an assembly. Background technique [0003] Rotary disc knives are used during the cigarette manufacturing process to recirculate tobacco from cigarettes that are damaged or rejected from the production line as being considered substandard and / or defective; Cut or perforate. [0004] In the case of cutting non-filter cigarettes, cut the carton along the entire length of the cigarette. In the case of filter cigarettes, the carton should only be cut along the tobacco portion, while the carton of the filter portion around which the filter is wrapped must remain undamaged. The task facing design engineers is to design a d...
