The Baby Wolf double back beam allows the warp to be divided into two parts, each controlled under separate tension. This is particularly useful for supplementary warps, seersucker, or double weave. The double back beam has its own warp beam and hand-controlled brake. It can be added to the loom at any time. The Baby Wolf can be folded with the double back beam installed. The depth folded with the double back beam is approximately 35".
