ABSTRACT:
An apparatus and a method for processing string materials, particularly electric conductors, includes at least one first string material guide for conveying the string material along a path of movement to a processing apparatus and including at least one second string material guide located between the first guide and the processing apparatus. The first guide means further includes at least one guiding element by which self-twisting of the string material about the longitudinal axis thereof may at least be impeded. The second string material guide includes another guiding element which is rotationally positioned about an axis arranged at a given angle with regard to the path of movement and is driven by a driving apparatus. The guiding elements are rotated either continuously or intermittently.
