ABSTRACT:
On a yarn, fancy twists arranged and formed at random shall be generated by a device added to the normal twisting device. To this end a fancy twist yarn thread is led through a pivotable fancy twist lever extending transversely to the moving direction of the basic yarn threads and is then led with the basic yarn threads to the cop of the twisting device. The fancy twist lever is deflectable by a fancy twist lever drive, such that the feed point of the fancy twist yarn thread moves along with the basic yarn threads. The fancy twist lever drive is controlled by an electronic control unit having a random generator.
