ABSTRACT A system for directing the tail of a web of flexible material to a predetermined location laterally offset from the normal path of movement of said web. The system includes a first Coanda nozzle directing a gaseous flow along a chute associated therewith and comprising a bottom wall and side walls, so that the gaseous flow induced by the Coanda nozzle entrains the web tail and causes it to move laterally about the web plane as it is directed to the predetermined location. A second Coanda nozzle is positioned downstream from the first Coanda nozzle and is angu- larly disposed relative thereto so that the web is again moved laterally about the web plane an additional incremental amount.
