  • the contact roller is supported capable of being displaced relative to the roller supporting member
  • the yarn winding machine comprises a control means for controlling the roller supporting member position adjusting means so that the space is within the range of 0.5mm ⁇ 3mm. Therefore, the yarn can be wound stably without the yarn feed roller and the package contacting against one another, and the free length of the yarn from the yarn feed roller to the package can be shortened, and the package with satisfactory shape can be formed. In addition, the change in the contact pressure of the contact roller to the package can be reduced.
  • control means controls the roller supporting member position adjusting means so that the space between the yarn feed roller and the package increases more than the predetermined range in a part of a process of a winding process.
  • the part of the process is the time less than twenty percent of the winding process from the start of the winding until the full wind is accomplished for one package. Therefore, the bad influence due to the increase in the percentage of the time in the process when the space is large, is prevented from being exerted to the winding form of the package, the condition in which both edges of the package in the axis direction become high (saddle bag) is resolved, and the final form of the package can be made satisfactory.
  • the yarn feed roller is provided to the upstream side of the contact roller that rotates by contacting to the peripheral surface of the package that is formed by the yarn being wound on the bobbin, rotates while contacting the yarn to be wound on the bobbin to supply the yarn to the package.
  • Such yarn feed roller is arranged to have a predetermined space from the peripheral surface of the package, and a yarn winding method is applied for winding the package by controlling the space to be constant irrespective of the package diameter.
