Pattern control is a state of the art system that eliminates the multi-treadle
dance of traditional looms and the tedious pegging of mechanical dobby
looms. Much like the legacy cartridge systems from the Compu-Dobby I and
II, the Compu-Dobby 5 stores entire weaving files (WIFs) onboard with three
significant advantages over all other systems:
 Ultra-fast pick writing. The system can achieve weaving speeds
in excess of 100 picks per minute.
 Hundreds of weaving files may be stored for later use.
 Eliminates latency timing issues inherent in computer
communications systems. Latencies can cause slower weaving
and even missed picks.
As a web enabled device, this loom connects to your computer or tablet via
WiFi or USB and controls the loom from your favorite browser. AVLDrive
version 5 is an easy to use, intuitive interface run from within the Compu-
Dobby 5. As a direct result, there is no software to install for the loom, nor
limitation on the controlling device, except for a minimum screen resolution
(
1024 x 768 pixels)
. AVLDrive is compatible with all major browsers, including
Safari, Chrome, Edge, Firefox and Opera. The current version of the browser
should be used.
Warp Beams and Automatic Warp Tension System
A first in our industry, some looms offer digital control of warp tension using
a small electrical motor and drive system connected via spring and brake
cable to the warp beam. The motor is controlled by the Compu-Dobby &
AVLDrive. Easily change the warp tension at any time during weaving by a
click of the mouse or a touch of the finger on the touchscreen. This system
allows very fine, repeatable control with a range from locked beam to free
turning for winding on the warp.
Note:
If you have a Compu-Dobby 5 on a loom with an automatic warp tension
system and automatic cloth advance, see the section starting on page 54 for
complete details on using these features.
Automatic cloth advance is an AVL-only feature on hand weaving looms.
Earlier mechanical versions of these systems are well known for providing
fine control over pick advance spacing. This feature utilizes digital controls
via an electric motor driven worm and gear attached directly to the cloth
beam. Much like the digital warp tension controls, set the picks per inch in
AVLDrive and start weaving. Easily change the advance setting or manually
