Abstract
Apparatuses and methods for producing an endless filter rod of the tobacco processing industry. An embodiment of the apparatus includes a transport nozzle loadable with compressed air, a guide tube, an elongated rod, which is arranged in the guide tube, having a rod projection, and an infeed roller, which is non-driven and freely rotatable, positioned immediately at an end of the transport nozzle and at a distance to the rod, and has a bearing surface that defines in sections a conveying path of a filter material web. The apparatus also includes a guide element positioned between the infeed roller and the rod by which a cross-section of the filter material web is reduced between the rod and the guide element in a region of the rod projection.
