摘要： A machine for cutting of the end of rod-like articles such as a rolled-up window shade. The article is held stationary and protrudes through a hole in the center of a flywheel, and a knife suspended from a lever pivoted on the flywheel cuts around the periphery of the article. A weight on the opposite end of the lever forces the knife against the flywheel by centrifugal action as the flywheel rotates.
