Abstract:
An open-end spinning apparatus that insures propagation of the rotary twisting of an open-end yarn from the point of withdrawal of said yarn from said open-end spinning apparatus to the entwinement point of fiber into said yarn, said apparatus comprising:a spinning element which converts said fiber into said open -end yarn; a fiber feed conduit which feeds said fiber to said spinning element for processing said fiber into said yarn; a thread guide proximal to said spinning element, which retrieves said yarn from said spinning element and guides said open-end yarn as it is withdrawn from said open-end spinning apparatus; a thread contact surface movably configured within said thread guide, said thread contact surface comes into contact with said open-end yarn as said yarn is withdrawn from said spinning apparatus; and a vibration element operably disposed to said thread contact surface, said vibration element causing said thread contact surface to vibrate said open-end yarn allowing propagation of the rotary twist of said yarn from within said thread guide to said entwinement point.
