Abstract
The apparatus employs two pairs of cutting discs which are diametrically spaced apart on a rotating drum to sever two filter plugs at a time from a travelling rod of filter material. The plugs are cut in uniform size, for example, in sizes between 5 millimeters and 14 millimeters and can be subsequently spaced apart so as to receive charcoal or other particulate filter material in the intermediate spaces. The drum rotates in synchronism with a recessed ledger through which the respective pairs of cutting discs pass to sever the travelling rod of filter material. Sharpening means are provided to maintain the cutting discs sharp.
