Yarn spinning method with high-speed winding

A method of forming and processing an advancing endless synthetic filament yarn, and comprising the steps of

• withdrawing a plurality of synthetic filaments from a spinneret and collecting the withdrawn filaments to form a yarn, and while advancing the yarn along a path of travel,
• drawing the advancing yarn,
• texturizing the advancing yarn at a location downstream of the drawing step,
• guiding the advancing yarn into contact with a feed system at a location downstream of said texturizing step, with said feed system including at least one rotating feed roll having a circumferential surface which defines a circumferential periphery, and including looping the advancing yarn about at least a portion of the circumferential periphery of said at least one rotating feed roll and so as to define a looping angle,
• selecting the looping angle of the advancing yarn about said at least one feed roll and a circumferential speed thereof such that the circumferential speed is greater than the speed of the yarn at the point it contacts said one feed roll, and such that the yarn slips with respect to the surface of said one feed roll and a frictional force is produced therebetween which is substantially speed independent, and
• withdrawing the advancing yarn from said feed system and winding the advancing yarn onto a rotatably driven tube to form a yarn package and including laterally traversing the advancing yarn along the length of the package and so as to form a traversing triangle which is located downstream of the yarn feed system.
