Abstract (en)
[origin: WO2006086909A1] The invention relates to feed shafts for spinning machines, in particular for teaslers or carders. Said feed shafts comprise one or more shafts, mostly an upper and lower shaft. According to the invention, the upward effect of undesired eddy currents within said shafts may be prevented, whereby a narrowing (20) is provided in an upper region (17) of the shaft (5) and the shaft cross-section (TU) increases again after the narrowing (20).
