Originally, we added "technical" features to the TDL which differentiated them from the other looms, but over the years, all of the "technical" aspects migrated to the Production Dobby Loom, so that when they went out of production, the only difference was the number of harnesses. Available over the years in widths ranging from 30" to 72".FDL: Folding Dobby Loom: 16 harness dobby loom. In production from 1982 to the present. Be aware, however, that in the 80's, we call them Production Dobby Looms too, differentiated from what we than called FULL-FRAME Production Dobby Looms.
