Abstract: A control device for actuating the weft carriers attached to opposed flexible tapes in a shuttleless loom. One end of each tape is attached to a driving arm with the opposite ends of the latter being fixed on oscillatably driven hub members. One side of each hub member has a disc element mounted thereon for movement therewith. The periphery of the disc members are disposed in operative association with the ends of the driving arms to which the tapes are attached and define platforms onto which the tapes are wrapped and unwrapped during their withdrawal from and insertion into a shed of warp threads by the driving arm.

Abstract: An improved start mark preventer for looms formed by a manually operable device including a double armed lever having a control handle mounted on one arm and a control pawl on the other arm. The control pawl is disposed in operative engagement with the loom's ratchet wheel which rotates its take-up roll by means of a feed pawl and hold-back pawl. The device includes a guide for the control handle with selectively positionable stop members that provide a neutral, first and second positions for the handle. Movement of the handle to the first position moves the fell forwardly of the reed's beat-up position, in the second position the fell is permitted to return to its initial position and upon starting the loom the control handle will automatically move to its neutral position.
