Abstract
The ring traveler (10) according to the invention has a noncoated core (20) which consists of iron material and which is provided with an, if appropriate, multipart nitrided edge layer (23; 24) at least in the region of the running surfaces (1) with which said core slides on a ring of a ring spinning or ring twisting machine.
Claims15
A method for producing a ring traveler (10) for ring spinning or ring twisting machines, which has a core (20) consisting of iron material, and comprising the step of subjecting at least a portion of the core (20) to a funding treatment during which heat energy and a nitriding agent as active medium are supplied to the core (20), wherein the method includes the step of oxidizing the core (20) after the nitriding treatment.
A ring traveler (10) for ring spinning or ring twisting machines, comprising an iron core (20) wherein at least one mechanically stressed part of the core (20) has a nitrided edge layer (23, 24), and wherein the edge layer (23, 24) includes a connecting layer (23) and a diffusion layer (24), whereby the connecting layer (23) has a thickness of 8 μm-12 μm and the diffusion layer (24) has a thickness of 100 μm to 200 μm.
