Dobby Head Installation

The dobby is placed on the right side of the loom under the harness
pulley support. Bring the dobby into position.

Note:

If you have problems placing the Dobby head correctly, loosen the harness

pulley support until you have the dobby head positioned and the bolts

tightened.

Figure 39 - Mounting the Dobby

Place the dobby head so that the two 5/16" x 2-1/2" carriage bolts
in the top of dobby backboard go through the top horizontal. The
bolt in the middle of the dobby back will go through the castle.

Secure each bolt with one washer and a hex nut.
