Abstract (en)

[origin: EP1927686A2] The frame has two direct current voltages sources of voltages (U1, U2), and three direct current voltage rails (18, 20, 22) attached to the voltages sources. The voltage rails are attached to the voltages sources for supply of different engines, such that one of the direct current voltage rails is common to the two current sources, and current collectors (28a-28d) are connected alternatively to two of the three direct current voltage rails, so that the sum of the voltages is available between the two rails. An independent claim is also included for a method for operation of a spinning frame.
