ころはない。As shown in FIG. 1, the covering system of the present invention places the peripheral surface of a package 4 of elastic yarn 3 in contact with a pair of support rollers 2 which are spaced apart and rotate at a constant speed. The elastic yarn 3 pulled out from the package 4 is fed to a feed roller 5 consisting of a pair of contact rollers, and the elastic yarn 3 fed out at a constant speed by the feed roller 5 is attached to a cover pulled out from another package 6. It is manufactured by winding the thread 7, and the manufacturing method described above is no different from the conventional method.
然しながら弾性糸３は摩擦抵抗が大ぎく、運転開始時パ
ッケージ４から引出された弾性糸３は、第１図に一点鎖
線で示したようにパッケージ４表面に吸着する。However, the elastic yarn 3 has a large frictional resistance, and the elastic yarn 3 pulled out from the package 4 at the start of operation is attracted to the surface of the package 4 as shown by the dashed line in FIG.

を防止する。Therefore, in the present invention, as shown by the solid line in FIG. 2 at the start of operation, the time t2 for the support roller 2 to reach constant speed rotation is longer than the time t1 for the feed roller 5 to reach constant speed rotation. Alternatively, as shown by the dotted line in FIG. 2, by making the rising straight line of the supporting roller 2 a curve that is gentle at first and then steeply rises, the circumference of the supporting roller 2 and the feed roller 5 can be changed. By changing the speed and applying tension to the elastic thread 3 between them for a short time,
To prevent the elastic thread 3 from adhering to the surface of the package 4 at the start of operation.

するのを防止することができる。In addition, contrary to the above explanation, the time required for the feed roller 5 to reach constant speed rotation is shorter than the time required for the support roller 2 to reach constant speed rotation, or the feed roller Of course, it is also possible to make the rising straight line of 5 a sharp curve and then a gentle curve, but in any case, a difference is created between the circumferential speeds of the support roller 2 and the feed roller 5, and tension is applied to the elastic yarn 3 at the start of operation. By applying it for a short time, it is possible to prevent the elastic thread 3 from adhering to the surface of the package 4.

ようになった。[Effects of the Invention] As described in detail above, the method of the present invention involves placing the circumferential surface of an elastic yarn package in contact with a pair of supporting rollers rotating at a constant speed, and applying the elastic yarn pulled out from the package to a pair of support rollers rotating at a constant speed. The elastic yarn is fed to a feed roller consisting of a pair of contact rollers, and the cover yarn pulled out from another package is wrapped around the elastic yarn sent out by the feed roller. By changing the circumferential speed of the feed roller and applying tension to the elastic yarn between them for a short period of time, at the start of operation, a short period of tension is applied to the elastic yarn between the support roller and the feed roller, and the elastic yarn is applied to the surface of the package. Prevents adhesion from interfering with smooth unwinding, and as a result, reduces thread breakage of elastic threads.
It has become possible to manufacture coverlink yarn with high efficiency.
