Electronic weft thread monitor for shuttleless weaving machines

摘要

The invention is concerned with an electronic device enabling an operator to easily and correctly adjust the time interval in which the weft insertion in shuttleless looms fitted with an electronic weft or filling thread monitor is to be monitored. A safety interval of some milliseconds' duration is provided at the end of said time interval taking into account the unavoidable fluctuations of the weft insertion period.
