How to Integrate Leno Knitting Healds and Leno Devices Into a Standard Dobby Loom for Fiberglass Net Production

Fiberglass nets—used in construction reinforcement, insulation, composite structures, and stone/tile backing—require a fabric structure that is both stable and dimensionally accurate. Traditional plain weaving cannot provide sufficient stability for fiberglass yarns, which are smooth, brittle, and prone to slippage.

To overcome these challenges, manufacturers increasingly integrate leno knitting healds and leno devices into conventional dobby machines. This upgrade transforms a normal dobby loom into a high-performance fiberglass mesh production machine.

In this article, we explain how the integration works and why Aydinleno’s leno technology makes the process simpler, faster, and more efficient.


Why Fiberglass Mesh Requires Leno Weaving

Fiberglass fibers behave differently from natural or synthetic yarns:

  • They do not grip each other easily

  • They are rigid and break under high friction

  • They slip if the weave is not locked

  • They need an open, stable grid structure

The leno weave structure—where two warp yarns twist around the weft—solves all these issues by locking the yarns in position. This is why leno is the standard technique for:

  • Marble & tile reinforcement nets

  • Drywall joint tape

  • Construction mesh

  • Roofing fiberglass

  • Composite reinforcement fabrics

To produce this efficiently, the loom must be equipped with a leno mechanism.


Can a Normal Dobby Loom Produce Fiberglass Mesh?

Yes — with the right leno integration.

A traditional dobby loom is designed for lifting warp yarns in sequence to create complex designs. However, it cannot produce the twisting motion required for leno weaving without added components.

By installing:

✔️ Leno knitting healds (leno heddles)

✔️ Aydinleno’s leno twisting device

a standard dobby machine becomes fully capable of producing high-quality fiberglass mesh.


How Leno Integration Works

Here is the step-by-step explanation of how the system is installed and how it functions:


1. Installing Leno Knitting Healds

Leno knitting healds replace or supplement standard heald frames.
They are designed to:

  • Hold the two leno warp ends

  • Guide them during twisting

  • Provide smooth and controlled movement

  • Prevent friction damage to fiberglass yarn

Aydinleno healds are polished, heat-treated, and shaped specifically to reduce breakage during high-speed twisting.


2. Mounting the Aydinleno Leno Twisting Device

The leno device is mounted on the loom frame and synchronized with the dobby movement.

It provides:

  • The twist–untwist motion that locks the weft

  • Controlled movement that prevents yarn breaks

  • High precision during high-speed production

  • Perfect grid formation for mesh fabrics

This twisting unit works independently but stays synchronized with the dobby harness lifting.


3. Synchronizing Leno Motion with the Dobby Program

The dobby controls the lifting pattern of the warp.
The leno device controls the twisting of leno ends.

To weave fiberglass mesh:

  1. The dobby lifts the open warp.

  2. The weft insertion takes place.

  3. The leno device twists the leno warp ends.

  4. The dobby prepares the next shed.

Aydinleno’s system is engineered to match this timing precisely, ensuring:

  • No conflict between movements

  • No tension spikes

  • Uniform fabric structure

Even at high production speeds.


4. Installing Leno Yam Supply (Creel Adjustment)

Because fiberglass leno ends require precise tension:

  • The creel must be adapted to ensure consistent feeding.

  • A tension-regulating system is used.

  • The path is aligned to prevent friction points.

Aydinleno provides recommendations for creel setup depending on yarn tex and loom width.


5. Calibration and Test Weaving

Once installed:

  • The twist strength is calibrated

  • The twisting frequency is adjusted

  • The dobby program is fine-tuned

  • A small weaving sample is tested

Aydinleno typically supports this process remotely or onsite.


Benefits of Converting a Normal Dobby Loom with Aydinleno Systems

1. Low-cost upgrade (instead of buying new leno looms)

Manufacturers save significant investment by upgrading existing looms.

2. High stability for fiberglass mesh

The leno structure guarantees perfect reinforcement grid quality.

3. Increased production speed

Aydinleno’s smooth motion reduces yarn breaks and machine stoppage.

4. Less maintenance and long component life

Even in harsh fiberglass environments, the parts maintain performance.

5. Compatibility with major loom brands

Aydinleno systems can be installed on:

  • Sulzer

  • Somet

  • Picanol

  • Dornier

  • Vamatex

  • Toyota

  • Staubli conversions

6. Perfect selvedge structure

Essential for fiberglass net width stability and downstream processing.
