Abstract
A bobbin creel is supported on a holder so as to be pivotable by a four-bar linkage arranged on the machine frame of a textile machine. The holder forms the stationary member of the four-bar linkage. The bobbin creel is pivotable from a lower loading position into an upper operating position by a pneumatic cylinder connected with one end on the holder and with the other end to one of the movable four-bar linkage members. For pivoting the bobbin creel from the upper operating position into the lower loading position, the pneumatic cylinder is a bidirectional pneumatic cylinder loadable at both ends with compressed air and a correlated actuating valve.
