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.

Guide block arrangement for a weft gripper tape

An operating system for the flexible gripper tapes in shuttleless looms in which the backing plate that limits upward motion of the tape is located in the region where the unwound tape is not engaged by the drive wheel, and which plate is provided with suitably disposed holes fed with compress air. The compressed air guides the tape and helps prevent undesirable buckling.

Backing plate arrangement for flexible gripper tape

A gripper tape drive device for a shuttleless loom, in which a circular disc is mounted coaxial but not perpendicular to the main loom shaft, its outer circular edge rotatably engaging a circular collar, of which two opposing pins spaced 180.degree. apart cooperate with the ends of a fork rigid with the control shaft of the gripper tape sprocket. Adjustment means are also provided for varying the amplitude of the oscillatory motion of said control shaft.
