CONSTITUTION: A strand S is formed by bundling a prescribed number of glass filaments 2 discharged from a glass melting furnace. A package 12 is formed by winding the strand around a collet 8a or 8b positioned on one spindle 7a or 7b of the turret head 6 of a winding machine through a traverse device 9 while traversing it. When the strand is fully-wound around the package 12, a yarn guide 10 is advanced, and the traverse device 9 is released and moved from the package 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention focuses a predetermined number of glass filaments spun from a glass melting furnace into a strand, and traverses the collet on one spindle of a turret head of a winder through a traverse device. The present invention relates to an improvement in a glass fiber winding method for winding a glass fiber to form a package.

[0002]

2. Description of the Related Art In the conventional method, when the package is fully wound, first, the traverse device is moved away from the package, so that the traverse device is separated from the strand being wound, and then the yarn guide is moved forward to move the package onto the package. The thread wound on the turret is moved to the position of the end cap of the collet, and in this state, the turret head is rotated 180 ° to automatically wind the thread on the other spindle.

[0003]

As described above, in the conventional method, since the yarn guide is moved forward after the traverse device is moved away from the traverse device, the yarn guide moves to the position of the yarn being wound on the package. By the time it arrives, the yarn will be untraversed and wound onto the package. This untraversed yarn is wound on the package in a state where it is not traversed, which causes a yarn entanglement during unwinding in a later process, which causes troubles such as yarn breakage and deteriorates workability. There are problems such as increasing the generation of waste thread.

An object of the present invention is to solve the above-mentioned problems of the prior art and, when the package is full, to prevent the uncrossed strands from being wound around the outer surface of the package as much as possible. To provide.

[0005]

In order to achieve the above object, the present invention is to bundle a predetermined number of glass filaments spun from a glass melting furnace into a strand, which is formed on one spindle of a turret head of a winder. A package is formed by winding the collet while traversing it through a traverse device, and when the package is fully wound, the yarn guide is first moved forward, and then the traverse device is moved away from the package.

Further, according to the present invention, a predetermined number of glass filaments spun from the glass melting furnace are bundled to form a strand, which is traversed by a traverse device on a collet on one spindle of a turret head of a winder. When the package is wound up to form a package and the package is fully wound, first, the yarn guide is moved forward, and when the yarn guide reaches one end of the fully wound package or an appropriate position on the fully wound package, the traverse device is moved. A command to move away from the package is issued, the yarn guide is continuously moved toward the other end of the full-wrapped package to the position of the end cap of the collet, and then the turret head is rotated by 180 ° to move it on the other spindle. The winding of the strand is switched to the collet.

[0007]

Since the present invention has the above-mentioned structure, when the package is fully wound, the yarn guide is first moved forward, and thereafter,
By moving the traverse device away from the package, it is possible to prevent the formation of unwound strand winding layers on the outer surface of the package.

According to another structure of the present invention, at the time when the traverse device moves apart, the yarn guide reaches one end of the full-winding package or an appropriate position on the full-winding package, and the traverse device moves out of the package. Even if the yarn moves away from the package and the traverse action on the yarn being wound on the package disappears, the yarn guide immediately pushes the yarn being wound to the position of the end cap of the collet.
It is possible to prevent the uncrossed strand from being wound around the outer surface of the package as much as possible.
