Abstract (en)
[origin: WO2009080750A1] A spool (20) made of thick metal sheet for a fine metal wire comprises a core (22), and two flanges (24), coupled to the core (12). The core (22) comprises two concentric drums, an inner drum (26) with inner diameter d, and an outer drum (28) with outer diameter D. The spool changes the load distribution of side pressure on the flanges and further improves the structural rigidity of the spool to against deformation.
