Abstract

A spinning device for producing a spun yarn by a circulating air flow in a housing has an adjustment device (17) for controlling the angular position of the fiber ends wrapped around a spindle head, and in turn, the angular position of the fibers wrapped around the produced yarn, by adjusting a linear component of an air flow into the spinning device as a function of the yarn withdrawal speed, whereby a yarn is produced of a required yarn strength even during a spinning start phase in the process of making the spun yarn.
