Permits the acoustic source to be located within a spread of 8% (approx.), the error, which is generally acceptable, arising from simplification of the equations for determining the co-ordinates of the source referred to a system of perpendicular axes associated with each lozenge, each axis cutting a diagonal of the lozenge at its mid pt.

Title: Open end spinning - in which yarn is false twisted and drawn after spinning to reorientate fibres
IPC: D01H4/00
Filed: 1974-08-05
Abstract: A yarn is withdrawn from the spinning rotor of an open end spinning machine by delivery rolls and fed through a false twist device (e.g. a false twist bush) to a pair of draw rolls operating at a faster speed than the delivery rolls. The false twist device operates in a direction which slightly untwists the yarn allowing it to be drawn and a drive mechanism controls the relative speeds of the delivery and draw rolls to achieve the required draw for a particular type of yarn. Pref. the false twist bush has removable inserts of different friction coefficients to control the false twist applied to the yarn. Drawing the yarn re-orientates the fibres, thereby increasing the strength of the yarn.
