A one-page dictionary entry describing a loom for weaving corsets, including the tubular pockets for whalebones and shaped gores. It explains how a Jacquard selects the part of the warp to be woven, how a thread-catcher removes unused weft loops, and how a regulator or take-up motion with levers and rollers adjusts for the changing cloth width. It also covers the elastic warp tension, and refers to the machine shown at the 1867 French Exposition.
