  • Patent number: 3999696
    Abstract: A system for directing a web of flexible material to a predetermined location and more particularly to a system for directing the free end or tail of the web into threading engagement with rolls forming a hip or the like. In the system a gas such as air is directed through a restricted opening under pressure whereupon it attaches itself to a flow attachment surface due to the "Coanda effect", is directed to the predetermined location and entrains ambient air. The tail of the web is placed into the path of the moving gas and entrained thereby. The gas is moving at a velocity greater than the velocity of the moving web and thus the web tail is straightened out and directed to the predetermined location.
