Abstract

In a loom a weft filament is fed from a supply and inserted in a weft direction through a warp so as to project from a downstream edge of the warp and the presence of the filament is detected by a sensor at the downstream edge. If no presence is detected, a deweaving device is operated that in a deweaving step strips the filament from the warp and ejects it therefrom past the sensor. A controller is connected to the sensor and loom for shutting down the loom when the sensor detects that no filament is ejected by the deweaver during and immediately after the deweaving step, shutting down the loom when the sensor detects a filament immediately after the deweaving step, and restarting the loom when the sensor detects a filament during but not immediately after the deweaving step.
