Abstract

A cigarette rod wherein a flexible tubular insert is surrounded by smokable material which, in turn, is surrounded by a wrapper of cigarette paper is formed by advancing the insert from a source at a variable speed toward one or more stations where the running insert is confined between two layers of smokable material. A combined monitoring and regulating system is provided to monitor the extent of sag of the insert between the outlet of the source and the confining station(s), to generate signals denoting the extent of sag, and to regulate the speed of a motor for the insert at the outlet of the source in response to such signals. The purpose of the combined signal generating and regulating system is to maintain the extent of sag of the insert between an upper threshold value and a lower threshold value.
