Abstract (en)
The mechanism to feed weft yarns into a rolling shed loom has a fixed unit (4) with a number of channels to feed the weft yarn (3), and a unit (5) which rotates with the loom rotor fitted with a number of injection channels (12) to propel the wefts into the shed. A number of jets (31) charge the feed channels with the wefts (3) from a supply bobbin, continuously or intermittently. The fixed unit has a holder (21) and an assembly (22) of channels in a curve, concentric at the holder. Compartment units form the channels. The feed channel can have a transport channel and an extraction channel, where the clear width of the transport channel is larger than that of the extraction channel. The channels are assembled into a component, where they have separate inlets, opening into a common outlet. The component has a number of units, with an initial section with the channels, opening into a second section with an opening. The channels are divided into groups, with at least one channel group in the component unit. The channels have a cross section which tapers towards the open longitudinal side. An auxiliary jet can be at the second section, aligned to the opening. The injector jets (12) are at an equal angular interval, on a common circle (24).
