Glasgarn, Verfahren und Vorrichtung zu dessen Herstellung

摘要

When one strand (5), which is formed by gathering a multiplicity of glass filaments (2) having a diameter of 9 mu or less and formed by drawing molten glass flowed out through a multiplicity of orifices formed in the bottom portion of a bushing (1), is wound around a collet (8), the strand is wound to form a square-end cheese package by traversing the strand by a traversing device (7) having a constant amplitude, while the strand (5) is brought into contact with a rotative drum of a tension relaxing device (6) to reduce the tension acting on the strand. Thus, the quality of a package (10) of non-twisted glass yarn having a monofilament diameter of 3 to 9 mu can be improved, a large quantity of the package (10) can be formed, and the package (10) can easily be transported.
