ABSTRACT:
A weft stretching and detecting device has a first section (1A) for stretching a weft thread and a second section (1B) for monitoring the arrival of a leading weft end (11A) either through a weft guide path (4, 7, 7B) which is aligned with a weft insertion channel (2A), or through a weft stretching guide channel (6, 9, 8) which is laterally displaced relative to the weft insertion direction defined by the weft insertion channel. The weft monitoring second section (1B) is mounted in a sley extension (3A) for a sliding movement axially back and forth along the sley extension (3A), whereby a spacing between the first section (1A) and the second section (1B) is adjustable. A single weft stop motion device (10) is mounted in the weft monitoring second section (1B) for monitoring the weft guide path and the weft guide channel for the arrival of a weft thread leading end through the guide path or through the guide channel.
