Abstract (en)
[origin: EP2058260A2] The cores (A, B) have end sections (6, 12) comprising front side sections (7, 16) at both ends, respectively. The end sections have deformation zones by which the front side sections are respectively connected to main portions (5, 11). The deformation zones are designed as attenuation zones (8, 13). The main portion is designed as a hollow cylinder, and the attenuation zone is formed by reducing wall thickness of the hollow cylinder. Triangular shaped circulating grooves (9, 14) are formed between the respective main portions and front side sections. An independent claim is also included for a winding core arrangement comprising rectangular slots.
