ABSTRACT:
An electronic sequencer for successively introducing a weft propelling fluid, such as air, into the successive nozzles of a fluid-jet loom is described. A plurality of separate control paths, individual to the succession of nozzles, each includes a triggerable pulse generator and an associated actuator connected in series with an electromagnetic valve that couples the propelling fluid to the successive nozzles. The pulse generator associated with the first nozzle in the sequence is triggered by a detector that is actuated once during each cycle of the loom. The remaining pulse generators are coupled to the output of an associated one of a plurality of delay circuits. The delay circuit associated with the second nozzle in the succession is triggered by the output of the detector, while the input of each remaining delay circuit is coupled to the output of the next-preceeding delay circuit. With such arrangement, the generation of an initiating pulse by the detector automatically cycles fluid to the successive nozzles with a duty cycle which is rapidly and easily adjustable by changing the pulse width and/or the retardation time of the pulse generators and the delay circuits, respectively.
