ABSTRACT:
The drum-shaped control device has a jacket which defines an air pressure reservoir and outlets which connect via air feed lines to the nozzles of the weft insertion device. A split rotary slide valve is disposed within the jacket so as to open each of the outlets in sequence to the pressurized air in the reservoir. The valve is driven by a hollow tubular shaft which is connected via pins to the valve. Air is delivered to the reservoir through the hollow shaft from one end of the control device. Operation of the moving parts during operation is compensated by the widening of the split valve due to the pressure in the reservoir.
