Abstract
A gear drive for shuttleless looms has an input transmission train and an outpost transmission train cooperating for converting the continuous rotational movement of the main loom drive shaft into an oscillating back and forth movement which in turn is converted into a horizontal back and forth movement of the respective gripper rod carrying a gripper head back and forth into the loom shed. The output transmission section or train has two auxiliary parallel output drive shafts, both of which are driven from a central output drive shaft. Two pinions at the free ends of the auxiliary parallel drive shaft mesh with the gripper rod, thereby distributing the drive forces over a larger surface area for reducing the wear and tear on the gripper rod and on the two parallel output drives.
