Abstract

In the method a weft thread which is supplied via a thread brake and a thread presenter is inserted into a shed by means of rapiers with a thread clamp, with the thread clamp being set in a freely selectable manner for each weft insertion during the weft insertion. This makes it possible to insert weft yarns of different types and thickness into a shed. The system comprises a rapier (1) with a thread clamp (4) and an arrangement (4) with a first apparatus (11) for setting the thread clamp and with a second apparatus (21) for the actuation of the first apparatus.
