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.
