[comp.periphs] Computer Controlled Looms

oster@dewey.soe.berkeley.edu (David Phillip Oster) (10/23/87)

I received an interesting brochure in the mail recently, describing an 
unusual computer peripheral:

A loom. From AVL Looms.

For the cost of a medium price laser printer, you can weave your output 
into fabric. I've always wondered, since Jacqaurd looms were the first
"computer" controlled output devices, why they weren't more popular for
the home market.

Their looms are available in 40", 48" and 60" widths,
allow warps up to 100 yards long.

Operation:

The loom has a left and right foot pedal, close enough that you can use 
a single foot. Tread alternately on the left and right treadle (foot pedal),
and the appropriate subset spring-loaded set of 16 harnesses raises. Flick 
your wrist to send the flying shuttle across the cloth, then push the beater
bar forward, then back to  press the new woof thread into the fabric. 
(I don't know enough about weaving to know whether you must manually move 
the shuttle across the warp, or whether it is done for you by the motion of 
the beater bar.) Periodically you stop, and crank the warp another notch on 
its ratchet, winding up completed cloth and revealing new bare, sections of 
warp thread. The computer interface is responsible for lifting the right
combination of harnesses in response to a press on the foot pedal.

Here are quotes from their brochure:
"with its 16 harnesses, the weaver can do 3 block Damask, fancy 16 
harness twills, up to 14 block summer and winter weaves and much more. 
In addition, when doing 12 and 14 harness weaves, 2 to 4 harnesses are
available for the selvedges." "produce between 2 and 4 yards an hour." [1]

[1] Oh well, so much for the dream of weaving at home some of the
complex Jacquard paisleys I have seen.

-----------------------
total price (low)	6774	4664	6069	6469	7569	[5]

[2] $995.00 buys a 4-box flying shuttle system, 
    $195 a 1-box flying shuttle system (40" loom)
    The low price is not a flying shuttle.

[3] The low price is a beam going all the way across the loom.
    The higher price ones are split. Presumably this allows
    dividing the loom for simultaneous weaving of independent 
    pieces of cloth 

[4] Software ranges in price from 75.00 to 300.00.

[5] I choose the minimum price options to arrive at these totals.

These looms require muscle power to make them go. I wonder how much
more a completely automatic rs232-loom would cost.

By comparison, the 4-color embroidery sewing machine I saw demoed at
MacWorld a few years ago, sold for about $10,000.00. It had 4 needles,
each atached to its own bobbin of thread, each in a different color.
It could handle about an 8"x10" area.  Are RS-232 embroidery sewing
machines any cheaper now? These could have an interface like a
standard 4-color pen plotter. Do they?

(Imagine accidently leaving output redirected to the wrong device, and
having your business correspondence woven or embroidered when you
meant to print it. (It would sure impress the recipient!)
