摘要

A tape drive system for the weft gripper of a shuttleless loom which uses a plastically undeformable tape formed of composite laminate layers containing rigid fibers. The tape is driven by a sprocket engaging perforations provided along the tape and the engagement is being ensured by two shoulder blocks. Additionally the tape is provided with a permanent magnet at that end carrying said weft gripper cooperating with a metal plate extending along the whole or at least part of a tape travel track.
