ABSTRACT:
An improved distributing arrangement for successively coupling pulses of pressurized fluid through a succession of active weft-propelling auxiliary elements distributed along the shed of a fluid-jet loom is described. A pressurized fluid distributing cylinder supported for rotation on a portion of the machine frame has a plurality of peripheral openings which extend in axial and circumferentially spaced relation along the cylinder. A plurality of rotary valves are associated with each of the openings, with each valve having a first apertured portion carried by the cylinder and a second cooperating apertured portion carried by the frame and urged against the first portion. During a rotation of the cylinder in synchronism with the rotation of the main machine shaft, the conduits in both portions of each valve means come into registration to provide communication between the interior of the associated portion of the cylinder and one of the active elements of the weft insertion section. A baffle or plug member may be disposed within the cylinder to divide the cylinder into separate fluid-feeding regions for the main weft insertion nozzle and the auxiliary elements, respectively.
