Metal Coil House For Industrial Sewing Machine

Industrial coil housing: the small part that determines the quality of the seam

In an industrial straight sewing machine, the bottom thread passes through the coil housing before it meets the top thread. The coil housing holds the coil in place, and with the help of a spring and a small screw, it determines how much tension there will be in the bottom thread. When the coil housing is worn, scratched, or deformed, the voltage goes awry: loops appear on the underside of the fabric, the thread tears, and the seam comes out uneven. Replacing a reel housing is often the simplest fix for a problem that seems complicated.

This coil housing is made of metal with a silver finish, with a cylindrical structure. It has a top latch with an opening, through which the coil housing is taken out and inserted into the machine, and a front opening through which the coil enters.

What's in it

• Top latch with opening: for holding and locking the coil housing in the machine.
• Front opening: for inserting and removing the coil.
• Metal cylindrical structure: Durable for continuous work.

Common Uses

• Replacing a worn or scratched coil housing with an industrial straight sewing machine.
• Another coil housing next to the machine, with a voltage directed to another wire.
• Spare parts in sewing factories, studios and repair shops.

Who is it suitable for

For sewing factories and workshops that work with industrial straight sewing machines, for tailors and repair shops, for sewing machine technicians, and for designers with an industrial machine in the studio. A home machine needs a different coil house, so before buying, it is important to make sure that it is an industrial machine.

Pro Tips

• Comparison to the existing coil housing: Before buying, compare the shape, size, position of the latch and the shape of the spring to the coil housing in the machine, or send us a photo on WhatsApp.
• Tension direction: Rotate the small screw on the spring a quarter of a turn at a time. Familiar check: Hold the coil housing with the coil inside it by wire, and shake slightly. The coil housing should come down slowly, and not fall all at once and also not get stuck.
• Cleaning: Clean lint from inside the coil housing and under the spring with each coil replacement.
• Two coil housings: Those who work with wires of different thicknesses can hold another coil housing with a pre-set voltage, and replace in seconds.

Common mistakes

• Tight rotation of the tension screw: Turning too much makes it difficult to return to the correct tension. Change slightly and test on a piece of fabric.
• Incomplete insertion: A coil housing that is not fully locked in place causes noise and needles to break. Insert until you feel the lock.
• Assuming that each coil housing is suitable for every machine: Reel housings look similar, but the small differences matter. Choose by machine.

How is it different from the home reel house on the website?

There is also a reel house for a home sewing machine with a long locking handle on site. It is a reel house for industrial machinery, and they do not replace each other. Suitable reels and other reel houses are in the category of reel and reel housings.
