from The Century Dictionary.
- noun A small instrument for drawing warp-threads through the splits or dents of a reed.
Sorry, no etymologies found.
Hand-drawn-in warps require two operatives: (i) a drawer-in sitting in front of the frame, selecting the healds in drafting order and drawing the ends through the eyes with a reed-hook and (ii) the reacher-in, working from behind the frame, selecting the warp threads in order from the beam, and presenting them to the reed-hook held by the drawer-in.
This is done with a wire hook called a sley-hook or reed-hook.
