Frequently asked questions
The questions we hear most about harnesses, parts and orders, on one page. If yours is not here, message us on WhatsApp.
Quotes and orders
Is the harness proposal free?
Yes. Tell us the job and the loom. If needed we visit your mill to see the loom, and the survey is free too.
Do you have a price list?
Prices depend on size, material and quantity, so we quote instead. Add the quantity to your message and we’ll quote for it.
I don’t know the size of the old part.
Send a photo. We’ll pin down the size together and make a sample if needed.
Can I get a sample?
Yes. If needed we make a sample first; you try it on the loom and we start the order once you approve.
Do you ship abroad?
Yes. We prepare export documents in Turkish and English.
Which machines do you work with?
Stäubli, Bonas, Grosse and Jakob Müller jacquards; Van de Wiele, Dornier and Picanol looms. Write to us about other machines too.
Harness building
How does a harness job run?
Survey: we see the loom, the jacquard and the fabric on site, no charge. Plan: hook count, comber board layout, heddle length and spring tension are set for the job. Preparation: heddles, springs, pulleys and cord are made up into a set in our workshop. Fitting: our team fits the harness on your loom and adjusts it.
Which tie types do you work with?
We work with Cenova, Belgian, Spinger and velour tie types. For low-density work such as prayer rugs we usually suggest a Spinger tie; our team confirms it for your fabric.
What is a jacquard harness?
On a jacquard loom, the harness carries the jacquard’s decision down to each warp end; its parts run from the module to the heddle. The same jacquard needs a different harness for different work.
Why does the warp keep breaking?
Not every warp break starts with the yarn. Heddle eyes, spring balance, worn parts and the comber board layout are where to look in the harness when breaks go up. Many warp breaks start at the eye: if the inside is rough or the shape is off, the yarn rubs on every pick until it breaks.
Parts
What is in a harness set?
A set usually holds a pulley, two quick links, a short cord and a long cord; some sets are knotted. The exact parts depend on the fabric and your machine. Tell us the machine and we will put the set together.
Why is every harness set different?
A harness set holds a pulley, quick links and cords, but its contents change with the jacquard, the fabric and the harness height. The jacquard make comes first: Stäubli, Bonas, Grosse and Jakob Müller jacquards use different connectors; a Stäubli quick link is not a Bonas quick link.
What does harness cord do?
In a jacquard harness, the cord makes the link between the pulley and the heddle. It runs down from the pulley under the jacquard, with the heddle tied at its end. When the jacquard lifts a hook, the movement passes through the cord to the heddle; the heddle rises and the warp end in its eye opens the shed.
What do we need to send the right cord?
Cord type and gauge (e.g. HETEX 410, KORD 1.0), colour, and quantity (spools or kg).
How long should the heddle be?
Heddle length depends on the loom and the height of the harness. The safest way is to measure a working old heddle end to end, or send us a photo. For heald frames, frame heddles come in 520, 580 and 620 mm.
How many grams of spring tension?
The length and tension of the spring that pulls the heddle down decide how cleanly the shed closes. Too weak, and the heddle won’t return; too strong, and the jacquard and cords carry extra load. Example: the 1020R has a 4.0 × 1.5 mm eye, a 24 cm spring and 60 g tension. The right value depends on the fabric and the jacquard.
Calculator and this site
How is the heddle calculation done?
Heddles per rod = top wires + bottom wires + (groups × steel per group). Each heddle item = rod count × its per-rod quantity; total = rods × heddles per rod. The long spring count equals top + bottom wire heddles; the short spring count equals the centre steel heddles. Jacquard work has no rods: loom width = width + 4 cm, dents/cm = reed ÷ 10, one course = width × dents/cm; total steel = course × colours; wire multiplier Velour 0, Spinger 1, Belgian 2, Cenova 4. Pulley sets = hooks ÷ tail, quick links = hooks, modules = hooks ÷ 8.
