ABSTRACT:
In blade changing devices the phase length of the oppositely rotating blades of a changing unit must be exactly determined to guarantee at the ends of the changing region a reliable thread transfer. When the arrangement is composed of several changing units, the first rotors are driven by a common drive belt in form of a flat multi-shaft transmission and the second rotors are driven by another common drive belt. Due to length deviations of the both drive belts phase errors can occur and lead to disturbances of the thread laying. In order to eliminate this, the first rotors of all changing units are driven by a single drive belt. The same drive belt drives also the second rotors through a separate intermediate transmission associated with the individual changing units. The arrangement is especially suitable for spooling machines for synthetic threads running with high speed.
