Sewing & Processing
Does your Keder spool fit your unwinding stand?
Specify the reel as well as the strip to keep material handling aligned with your sewing process.

The solution at a glance
Confirm reel dimensions, mounting and feed behavior alongside the strip specification, then preserve the approved setup.
- Check core diameter, spool width and equipment clearance.
- Keep the reel centered and check shaft alignment and free rotation.
- Evaluate feeding and tension over a representative production run.
Why does spool compatibility matter?
Flat keder can meet the required strip dimensions yet still be inconvenient to handle if the spool does not suit the workstation. Reel mounting, unwind direction and the path into the sewing machine all matter to the production trial. Review these details before ordering material for a new line.
BIVO's standard packing is 200 m per spool and two spools per carton. Confirm the arrangement for your selected material and profile, especially for silicone or custom specifications. Spool length alone does not establish whether the reel will fit your holder.
- Identify the current reel holder and mounting arrangement.
- Check spool dimensions and central opening.
- Describe the feed path to the sewing machine.
Which spool and stand dimensions should you check?
Compare the proposed reel with the available space at the workstation. Check how it mounts, whether it can rotate as intended and whether neighboring equipment interferes with the strip path. Use the equipment manufacturer's guidance for mounting and operating the holder.
If the workstation uses an automatic feeder, share its relevant requirements rather than assuming any spool can be installed. A photograph with dimensions or a holder drawing can help clarify the request. Confirm these details alongside material and profile rather than leaving packing until dispatch.
What can cause uneven feeding during unwinding?
During a controlled trial, observe whether the strip arrives at the sewing point flat and consistently oriented. Twists, contact with surrounding surfaces or an awkward change in direction may affect handling. Inspect the whole route instead of focusing only on the final guide near the needle.
Follow the machine manufacturer's procedures before making any adjustment. Check the holder and guides when movement appears uneven. Do not use a material change as the first response to a feed issue that may originate in the reel mounting or the workstation layout.
- Look for twisting or edge contact along the route.
- Observe whether reel rotation is interrupted.
- Compare the setup with a previously successful reel.
How long should a production trial run?
A short sample can establish basic sewing behavior, but it may not represent a mounted production spool. When reel compatibility is important, arrange a trial that includes the intended packing and enough operation to assess handling under your normal process.
Record any interruptions and where they occur. Note whether the symptom relates to mounting, strip orientation, a particular part of the reel or a machine adjustment. Keep material and spool references together so the supplier can understand which combination was evaluated and discuss the next step.
What packing details should you confirm for repeat orders?
After approval, retain the agreed strip specification, length per spool, reel dimensions, mounting requirements and carton arrangement. Add any labeling requirements that help receiving staff connect a delivery with the correct production job. Custom requests should be confirmed in the quotation.
If you change sewing equipment or reel holders, revisit the packing approval before the next order. Send BIVO the relevant holder details, preferred spool length and current handling observations. A clear packing brief helps align the delivered reel with the process that was actually tested.
- Record the approved spool and holder combination.
- Confirm material-specific packing with the order.
- Keep a photo of the successful workstation setup.
