Abstract
In a shuttleless loom a weft filament is inserted pneumatically in a weft direction through a warp shed by a nozzle on one side of the shed and is caught by a pneumatic aspirator aligned in the direction on the other side of the shed from the nozzle. A mechanical brake aligned in the direction on the other side of the loom with the aspirator, either immediately upstream or downstream therefrom, mechanically engages and holds the yarn after same has been caught by the aspirator. This brake can be formed by a tube with an internal brake element defining a nonstraight passage or can be a pinch brake to one side of a guide arrangement that pushes the filament laterally into the pinch brake once the filament is all the way through the aspirator and some tension is applied upstream in the filament.
