Abstract

594,573. Paper tubes. RIEGGER, P.C. Sept. 4, 1945, No. 22738. Convention date, Nov. 4, 1943. [Class 94 (ii)] Cutting mechanism for paper tubes, or the like, comprises a rotary cutter 1, the linear speed of the cutter being at least equal, to the linear speed of the tube and a stationary cutter 2 fixed to a former 3 for shaping the tube in which the slits in the tube walls are so disposed and shaped as to detach waste cutting of the paper or other material. The cuts may be of various shapes, formed in either or both walls of the tube and two or more cuts such as C, C<1> may be formed to enclose a piece of material to be removed. The tube may afterwards be cut up along lines A A<1> to form section F<7>. The cuts may be at an angle to the line of movement of the material.
