A winding machine without anti-patterning device has the following particulars:Cylindrical winding drum diameter : 75 mmNumber of crossing on drum           : 2 1/2Rotational speed of the drum          : 2860 rev/minTraverse length                                   : 150 mmA 3.5 degree constant taper cone is built on the above cone winder with no movement of the point of drive during the package build up. At mean cone diameter of 150 mm the package rev/min is 1375.Distance in mm of point of drive from the base of the cone along the traverse is approximately
