ABSTRACT:
A two-sided ring-spinning machine has a frame and a pair of parallel spindle banks each holding a respective row of bobbins. A bobbin-changing apparatus has respective gripper beams engageable with the bobbins of the spindle banks, respective scissor linkages pivoted on the frame and on the gripper beams extendable for raising the respective beams and collapsible for lowering the respective beams, and a single force-transmitting element connected to both of the linkages and displaceable longitudinally in one direction for extending the linkages and in the opposite direction for collapsing the linkages. A single drive is connected between the frame and the force-transmitting element for simultaneously vertically displacing both beams.
