Estimating the term…
The two-phase gripper loom or weaving machine comprises two loom units arranged adjacent one another. Each of their heald frames can be actuated by a heald frame positioning device with a phase shift of 180 angular degrees. Each heald frame positioning device is associated with a related one of the loom units. There is arranged between the common main shaft of the machine and the two rotary shafts of the two heald frame positioning devices a clutch drive for selectively individually connecting or coupling one or the other rotary shaft with the main shaft of the machine or with an auxiliary drive. This enables, during standstill of the machine, to bring the open weaving shed of one or the other loom unit into a closed shed position until the gripper loom is restarted, prior to which restarting the closed weaving shed is brought back again into the open shed position.
In a method of operating a two-phase gripper weaving machine containing two juxtapositioned loom units each having heald frames operated by a heald frame positioning device containing heald frame cam means and respectively movable into open shed and closed shed positions and a respective rotary shaft operatively correlated with each loom unit, the loom units working in phase opposition to one another and the rotary shafts being conjointly driven by a weaving machine main shaft, the improvement which comprises the steps of:
A two-phase gripper weaving machine comprising:
