Abstract
In apparatus for causing rod-like articles to roll through a channel defined by opposed surfaces in which rolling is caused by relative movement of the surfaces, the channel is provided with a region of reduced width at the point of entry of the articles into the channel so that there is a positive start to rolling. A particular application is in a filter cigarette assembly machine in which axially aligned filter and tobacco portions are joined by wrapping them in a 'cork' section while they are rolled through a channel between a rolling drum and a rolling plate.
