Patent ID: 8079206

Claim:
A ring spinning machine, comprising: a. a drafting unit, a twisting and winding unit for twisting yarn and fleeces, and a control unit; b. said drafting unit comprising: i. a series of horizontally aligned drafting rollers rotating at different speeds to control the thickness, twist and weight per unit length of a yarn; ii. said drafting rollers being individually motorized by controllable roller motors to control the speed of the rollers; c. said twisting and winding unit comprising: i. spindles, rings, ring rails, yarn guides and a reciprocating chassis; ii. said rings rigidly connected to the ring rail; iii. said ring rail fixed in place and location relative to the drafting unit; iv. each said spindle being a vertical rod having a spool, whereby the resulting yarn from the drafting rollers winds on the spool; v. each said spindle arranged coaxially in an inside space of a ring; vi. each said ring having a ring guide, passively revolving around a rotating spindle, whereby the yarn after leaving the drafting rollers is guided through the guide carried on the ring, locating and twisting the yarn as it winds on the spool; vii. each said spindle having an individual controllable spindle motor to control the speed of the spindle; viii. said spindles and spindle motors fixed on a chassis; ix. said chassis connected to a cam providing a reciprocating up and down motion to the chassis, thereby, moving the spindles in a reciprocating up and down motion, and thereby said spindles go through the rings in an up and down motion as the spools fill up; whereby, the ring guides move in a circular motion in a constant plane, while the spools pass through the rings in a reciprocating up and down motion so that the winding is uniform and untangled, and whereby the rotating speed of each spindle can be controlled individually to reduce breakage of the yarn.
