Problems solved by technology
[0011] This leads to the problem that the cross-section of the wire guide tube must be deformable so that it can be pressed into the groove and adjusted to its dimensions, and that a great deal of effort and time is required for mounting and removing the wire guide tube

Embodiment Construction
[0063] figure 1 a) shows a side view of a rotor bow 1 according to the invention, which has a body 2 which has a curved shape at the left-hand end on the insertion side (due to twisted or stranded strands between the end at which the thread enters the rotor bow) and the right-hand end on the turning side (because the twisted or twisted multi-core strand turns at this end and is led to the winding tube) extend. The body 2 of the rotor bracket 1 is formed in this exemplary embodiment from fiber-reinforced plastic and is formed as a solid part without cavities (except for the slots 3 , fastening cutouts 8 and other holes, which are described in greater detail below).
[0064] The rotor bow is preferably suitable for processing bare wire strands such as seven-wire strands, preferably made of copper alloys such as CuMg, especially CuMgO2 (i.e. with a magnesium content of 0.2%), CuAg, CuSn, etc., with a maximum diameter of 1.5 mm 2 Small cross-section, high number of blows, prefer...

Abstract
The invention discloses a rotor bow (1) for a twisting or stranding machine, said rotor bow having a body (2) with a slot (3) in said rotor bow ( The longitudinal direction of 1) extends substantially over the entire longitudinal extent of the rotor bow (1). The rotor bow (1) has a tubular guide element (4), in particular a helical spring, for guiding the elongated multi-core strand, said guide element (4) being continuous and essentially in said groove ( 3) is arranged in the groove (3) over its entire longitudinal extent. At each location of the longitudinal extension of the guide element (4), the inner dimensions of the groove (3) are greater than or equal to the outer dimensions of the guide element (4) at that location. This makes it possible to easily remove, preferably extract, the guide element (4) from the groove (3) and to introduce, preferably insert, it into said groove (3).
Description
[0001] The entire content of the priority application DE 10 2014 011 722.3 is hereby incorporated by reference into an integral part of the present application. technical field [0002] The invention relates to a rotor segment, in particular for a machine for processing elongated multi-core strands, such as a twisting or stranding machine for twisting or stranding strand-like material, and to Such a machine with a rotor bow according to the invention. Background technique [0003] The strand-like material is preferably a metallic material, such as copper, steel or aluminum wire or an insulated or non-insulated metal conductor, which has a different alloy composition, or also a non-metallic material, such as natural fibers or man-made Fibers in which multiple strands of this material are intertwined with each other by twisting, ie processed into a strand. However, the strand material can preferably also be such a litz wire, wherein a plurality of strands of such a litz wire ...
