Abstract
A method and a device for producing a crimped multifilament thread are described. A multiplicity of filaments are extruded by means of a spinning machine, cooled and subsequently treated by a drawing device and a crimping device to form a crimped thread. Before the thread is wound up to form a bobbin, a multiplicity of intertwining knots is produced on the crimped thread by a treatment device. In order to obtain defined patterns of the intertwining knots within the thread, a pulse sequence of compressed air pulses at a predefined frequency is directed at the thread. The treatment device has a controllable blowing means.
