It was a frame loom, equipped with treadles to lift the warp threads, leaving the weaver's hands free to pass and beat the weft thread. [48] A pit loom has a pit for the treadles, reducing the stress transmitted through the much shorter frame. [49] In a wooden vertical-shaft loom, the heddles are fixed in place in the shaft.
On a Lancashire loom weaving grey cloth, this was a simple but time-consuming task, but for a complex pattern on a Jacquard tapestry loom, great care was needed. To do this, the new beam was mounted on the back of a drawing-in frame, the healds were held next in a vertical position, and in front the reed would be clamped.
