INTRODUCTION

About AVL

AVL Looms has been in the business of designing and building some of the

world’s finest handweaving looms since 1977.

Jim Ahrens had been building and designing looms for a number of years

before Jon Violette, the “V” in AVL, approached Ahrens about a partnership

in 1977. Violette, an industrial management professional, had discovered

Ahrens’ work through his sister who ran the Pacific Basin School of Textiles

in Berkeley, where Ahrens was a volunteer advisor.

The two men worked together in the Bay Area for three years until Violette

moved Ahrens and Violette Looms to Chico, where it officially became known

as AVL Looms Inc., and has operated ever since.

In 1982, Violette was instrumental in the development of the first

computerized dobby, then called the “Apple Dobby”. He retired from active

life in the company in 1987. We have christened this new V-Series Loom in

recognition of Jon’s contribution to handweaving.

Once known for our production looms, AVL has broadened its line

considerably and we now offer customers a full spectrum of fine weaving

equipment, ranging from our small Home Looms, to our Industrial Dobby

Looms, Rug Looms, and Jacquards.

The V-Series Design Concept

We wanted to design a loom with a dynamic mix of simplicity and

sophistication, a “no frills” approach for weavers who want complex weaving

capability in a more fundamental package. We have streamlined this loom so

you get a lot of harnesses and strength on a small rugged loom. We hope

you will have many years of weaving from your new V-series loom. This

manual will guide you through the process of assembling your new loom and

will also cover warping and weaving with your new loom.

LOOM FEATURES

Brake System

Your V-Series Loom is equipped with a locking brake system. This means

that the Warp Beam will not release warp until you depress the Brake Pedal.

It’s fairly foolproof and affords very taut warps. When your fell has moved as

far forward as you’re comfortable, and you wish to advance your warp,

quickly depress the pedal with a short, tap-type motion and crank the warp

forward with the Cloth Advance Handle. If you are using two warp beams,

each will have its own brake pedal which must be depressed separately.

Tension Device

The tension device is an optional feature that allows you to advance the

warp without depressing the brake pedal. You will find that you can weave

with less warp tension with a weight control than with the conventional

ratchet system. Once the correct tension adjustment is made, it will be

maintained automatically as the weaving is advanced. For light, fragile

warps, it may be necessary to use a lighter weight than the one that comes

with the loom and for dense, heavy warps, you may have to add some

weight to the arm. You can order half size weights from AVL Looms. This can

be used by itself for very light tension or can be used with the existing

weight if more tension is needed.

Cloth Storage System

The Cloth Storage System consists of the Cloth Storage Beam (immediately

in front of your knees), the Cloth Storage Apron, and the Cloth Advance

Handle and pawl.

Removable Breast And Separation Beams

You will have either two or three of these Beams which are interchangeable.

They enhance the structural integrity of the loom and serve to establish the

warp in its horizontal plain. The Beam at the front of the loom is called a

Breast Beam; the Beam at the rear, the Back Beam, or Separation Beams, if

you have two Warp Beams. These Beams can be moved to the interior slot

to help with winding-on and threading.

Swinging Beater

The Swinging Beater is a standard feature of the V-Series Loom. You can

choose to have the swinging beater replaced by a sliding beater when you

buy your loom.

Sectional Beam

If you have purchased a Sectional Beam, you will find it to be extremely

adaptable to your needs. Because each of its hoops is removable, you may

create sections of any width you like, provided they are calculated in one-

inch increments.

An AVL Sectional Beam with metal hoops has holes for the hoops at 1”

sections. The wheel comes with enough metal hoops to setup 2” sections.

More hoops can be ordered from AVL if narrower sections are desired. For

wider sections, remove as many metal hoops as needed.

There are two things to remember:

1. You may only use a Sectional Beam in the upper position.

2. You cannot use two warp beams when using a Sectional Beam

Plain Beam

The Plain Beam is provided with an apron, which will allow you to maximize

the length of your warp. The V-series loom allows you to use two plain

beams at once.

Dobby Head And Compu-Dobby

The Dobby Head works in tandem with the Compu-Dobby and together they

provide the interface between your computer and loom.

E-Lift

The E-lift replaces treadles on your loom and allows the shafts to be lifted

easily and smoothly by pressing a pedal. The E-lift works independently of

the Compu-Dobby.

Harness Springs

There are two springs for each harness which stabilize the harnesses and

encourage their vertical fall when the shed is released.
