Method and Apparatus for forming a package including a steps of drafting and twisting a raw sliver to form a spun yarn, taking up at least two spun yarns in a paralleled state into the same package, and supplying the thus wound package directly to a two-for-one twister disposed in continuity with the spinning device. The spinning device and the two-for-one twister are connected to each other by a conveyor for feeding the packages from the spinning device and by a yarn supply package replacing device.

Method and apparatus for producing yarn

In a winder, a cover is provided at a portion of the winder where fluff is very likely to occur; that is, the portion is the position of a yarn feed bobbin, and the cover operates to cover this portion, thereby enclosing the fluff therein, and a suction pipe is connected to a part of the cover to discharge the fluff by suction.
