Louet Octado Fly Shuttle Mechanism
The mechanical dobby is a program bar with pegs system. The numbered holes in the program bars correspond with harnesses of the loom. If you want a harness to be raised, you place a peg in the corresponding hole of the program bar. Your series of program bars can be as long as you like; however, if the number of program bars becomes very large, you may want to consider an electronic dobby.
