Connect The Air System Page | 57
Your loom is now ready to be hooked up to a compressed air line. This line
will be connected to the FRL unit. You need to purchase a fitting to hook up
to your air line. For convenience, we suggest that you use a "quick
disconnect" type fitting which can easily be released from the loom without
any tools. You will need to buy a male fitting with either 1/4" or 3/8" pipe
threads to thread into the FRL. A corresponding
female
connector will be
needed for the hose end.
It's helpful if you buy a fitting that already has a sealant applied to its
threads. Otherwise, wrap the threads with Teflon tape to avoid a leak. Please
do not use pipe dope; it becomes scaly and can contaminate the air
components.
This is your first opportunity to test the loom's function. This test will
establish that your air connections are tight, that the harnesses move
smoothly, and that the Warp Beam Brakes are working. We've pre-adjusted
the operating speeds and pressures, but you may need to add a few minor
tweaks to achieve a particular result. It's always possible that something
was put out of adjustment in handling.
1) Once the loom has been hooked up to an air line, set the
regulator to a pressure range that will operate the cylinder to your
satisfaction.
2) Put the Main Air Valve handle in the OFF position.
3) Turn on the compressor.
4) Listen for air leaks in your main air delivery line.
5) Open the Main Air Valve.
6) Start the FRL at about 75 PSI. You may wish to change this
adjustment when you change weaving patterns as you will find
that a higher pressure is needed when you are lifting more
harnesses.
Note:
We pre-set the pressure at the FRL at 75 p.s.i. Please check it now and re-
calibrate the dial if necessary. Your loom will operate at between 75 and 120
p.s.i., but it's best to start at the lower setting.
7) The dobby can now be activated by depressing the foot valve. The
speed of how quickly the harnesses lift (your weaving speed) can
be further altered by adjusting the flow control valves.
8) Test out any other air components on your loom.
