D13-4 12E Collarette Binder 12mm (32mm Fabric Strip) for Baby Lock Coverstitch, Ovation & Gloria
Â
The Baby Lock D13-4 12E Collarette Binder is a premium, specialized industrial-style attachment designed for domestic coverstitch and multi-thread serger machines. Featuring a 4-ply (double-fold) structural base, this tool folds raw fabric strips evenly on both the top and bottom sides simultaneously. It accommodates a precise 32mm input tape width and collapses it down into an ultra-clean 8mm finished binding width. Built with an integrated guiding rake, the tool prevents rolling, minimizes twisting, and applies slight structural tension to the binding tape. This mechanical precision ensures flawless, professional-grade edge finishes on both high-stretch knit jersey textiles and stable woven materials.
3 Sewing Applications
-
Garment Necklines: Creating clean, durable finishes on t-shirt collars, sportswear neck openings, or delicate baby bodysuits.
-
Armholes and Cuffs: Binding sleeveless knit tank tops or finishing fabric edges on sleeves before final side seam assembly.
-
Pocket Openings & Curved Edges: Adding a visual pop or structure to apron edges, pouch openings, and rounded bags.
Recommended Application Methods
-
Angle Pre-Cutting: Always cut the leading edge of your 30mm binding tape into a sharp "<" or diagonal wedge shape to facilitate effortless feeding through the metal funnel.
-
Serpentine Flossing: Weave the fabric strip systematically through the built-in zigzag serpentine guiding rake with the fabric's wrong side facing you to manage input tension.
-
90-Degree Foot Pivot: Use long tweezers to grab the tape tail out of the funnel exit, pull it firmly, and pivot it exactly 90 degrees backward underneath the presser foot.
-
Tension Stitch Testing: Sew a few test centimeters onto the tape alone to confirm needle alignment before slowly sliding your main fabric edge into the folded binding core.

User Question Scenarios & Solutions
Scenario 1: Why is my knit tape bunching up inside the funnel and refusing to slide out smoothly?

Scenario 2: The needles are completely missing the underside of the folded binding strip.
-
Solution: Loosen the binder’s two physical hand attachment screws and manually shift the entire metal unit left or right until the left coverstitch needle pierces cleanly through the binding layers.
Scenario 3: Where can I get this exact accessory?

3 Safety Precautions
-
Power Down During Installation: Always completely switch off the machine's power button before anchoring the binder base to the table holes using the thumb screws.
-
Keep Implements Clear of Needles: Never use metal tweezers or screwdrivers near the presser foot zone while pressing the foot pedal.
-
Control Your Stitching Speed: Maintain a slow, highly controlled sewing cadence while hand-guiding fabric into the binder mouth to avoid finger slips near the needle bar.
