Abstract
An integrated doubling and twisting method includes the step of arranging at least two supply bobbins coaxially above one another in a protective pot of a bobbin support. The at least two supply bobbins are connected to one another, and the bobbin support together with the at least two supply bobbins is rotated. The individual spun yarns from the bobbin supports are removed in the direction of the axis of rotation of the bobbin support. One of the individual spun yarns is removed in clockwise direction and another one of the individual yarns is removed in counterclockwise direction. This feature can also be applied to a method in which a balloon limiter is provided and the individual yarns are guided through a hollow spindle axle.
