GETTING THE LOOMGETTING THE LOOM
Congratulations on your purchase of an AVL Dobby- Jacquard Loom. It’s time to get to know your loom. Please read the manual before using the loom. Figure 1 - Side View reveals some of the major components. Note your loom comes with two Jacquard heads and eight harnesses. Each head includes 336 hooks that are connected to the heddles, springs, and a tie down rod.

Figure 1 –SIDE VIEW
Tension is set on the heddles while air pressure (about forty p.s.i.) is applied at the Heddle Tension Cylinder. Later, we will address warping the loom ... for now, lets get the loom set up.

The Control Unit houses the Integrated Circuit Boards that control the hooks. Hooks on each head are arranged in twelve lines of twenty-eight hooks per line.Control Unit

Figure 2
PLEASE NOTE THE NUMBERING SYSTEM STARTS WITH THE REAR LEFT HOOK (as you’re facing the loom) MARKED AS HOOK #1. This is very important when you set up the loom and software. Again, rear left (first row) is hook #1; the last hook in row #1 is hook #28 located at the front of the row. Rear left, second row is hook #29 and so on. Each set of fourteen hooks has a connectioncable that is connected to the Control Unit. Each row is numbered both on the Jacquard Head and at the Control Unit. The Control Unit is connected to the controlling computer via a single RS-232 Cable.
