ABSTRACT:
To move pile heddle frames between three or rather four shed positions, a four-position rocking lever is arranged between two adjacent heddle frame lifting units and the rocking lever controlling the heddle frame. The free end of the first lifting unit rocking lever is a hinge point for the four-position rocking lever and the free end of the second lifting unit rocking lever is a hinge point for a connecting bar extending to the four-position rocking lever. To reduce wild movements of the heddle frame, no loaded shafts are provided in the power-transmitting path from the lifting unit to the heddle frame, aside from shafts supporting the lifting units and the rocker arm of the heddle frame.
