Abstract

925,318. Grinding cigarette-rod cutters. ZAVODY V. I. LENINA NARODNI PODNIK. Aug. 2, 1960 [Aug. 3, 1959], No. 26673/60. Class 60. In a method of grinding a sickle-shaped cutting knife whilst carried at the periphery of a rotary head, as in the cutting mechanism of a cigarette-making machine, the knife 1, Fig. 1, is so mounted on the head 2 that the rotation of its edge generates a substantially conical surface of revolution 6 and a fixed conical grinding wheel 5 is located in the path of the knifeedge. The projection of the blade width by parallel lines 8 determines the required minimum width of the cutting face of the wheel 5, the shape of the blade edge being as shown in Fig. 3.
