c. Attaching coated steel cables
– There are 4 cables to attach. Do not unwrap the
packaging securing the cables until instructed to do so herein. Start with the cables
attached to the cam-cylinders.
i.
Unwrap the cable from the cylinder of the “lifting” cam-cylinder, extend it up and
attach it to the slide plate or dobby arm.
1. If attaching to the slide plate the cable will end in a loop. The loop slides
over the open eye bolt at the bottom of the slide plate. If he eye bolt is
closed, then use the supplied quick link to connect the cable to the eye bolt.
2. If attaching to a post-1988 dobby arm, the cable will end in a crimped
ferrule. The ferrule end of the cable will be inserted in the bottom
“R” (as
marked in 1.a. above) hole in the dobby arm. Pop the ferrule up and out of
the top of the dobby arm, attach the black plastic cable retainer button, and
then pull the cable back down to seat it and the button in the dobby arm.
3. If attaching to a pre-1988 dobby arm, the cable end will be stripped of
sheathing. A loose ferrule will be supplied. Push the cable up through the
“R” hole and then using a crimping tool, crimp the ferrule onto the stripped
end of the cable. Note: Crimping the ferrule requires multiple squeezes to
ensure the entire ferrule is compressed and smooth. This ensures optimal
strength of the crimped joint.
ii.
Unwrap the cable from the cylinder of the “lowering” cam-cylinder, extend it up
to and over the small pulley in the upper right corner of the dobby head, then
down to the slide plate or dobby arm and attach it. Note: The small pulley on
the slide plate equipped looms will have a cable retainer. The cable retainer is
adjusted by loosening the center mounting bolt in the pulley. Loosen the
retainer and slide it up to allow for installing the cable. Once the cable is
installed, lower the retainer down and as close as possible but not touching the
pulley, then tighten the center bolt to secure the retainer position.
