A cigarette rod which is repeatedly severed by the orbiting knife of a cut-off is supported by a tubular guide which has a slot for the knife and is moved with the rod in the course of each severing operation to thereupon move back to a starting position. The guide is rigidly connected to and is moved back and forth by the head of a connecting rod which is driven by an eccentric pin and is fixedly connected to the upper end of a single leaf spring. The lower end of the leaf spring is affixed to a stationary support. The head of the connecting rod moves the guide forwardly while the pin advances along the lower portion of its circular path, and the internal surface of the guide is designed in such a way that it supports the rod from below during severing but is spaced apart from the rod during movement to starting position.
