Method and device for winding yarn onto a conical spool body

An apparatus for winding yarn onto a conical spool sleeve, said device comprising:

• a pivotable spool support frame for supporting said conical spool sleeve;
• a first drive unit for driving said conical spool sleeve and thereby winding the yarn onto said conical spool sleeve to form a spool body;
• a reciprocating yarn guide having a detection apparatus for detecting an actual placement position of said reciprocating yam guide along a length of said spool body to be used as a first parameter, wherein said detection apparatus comprises a second drive unit drivingly connected to said reciprocating yarn guide wherein switching pulses of said second drive unit are used to determine said actual placement position of said reciprocating yarn guide;
• a sensor for detecting a changing diameter of said spool body to be used as a second parameter;
• a computing and control unit in which the first and second parameters are processed to control signals supplied to said first drive unit for controlling a rpm of said first drive unit;
• and
• a means for adjusting a translatory speed of said reciprocating yarn guide based on said actual placement position such that said translatory speed comprises a maximum speed at a small diameter end of said spool body and a minimum speed at the large diameter end of said spool body.
