Why is the Topstitch Needle Identified as 130 N?

A few months ago, we discussed the numbering system of household sewing machine needles. The majority are known as 130/705 H needles:   130/705 H (Universal), 130/705 H-E (Embroidery), 130/705 H-Q (Quilting), etc. However, the SCHMETZ Topstitch Needle does not follow that numbering convention. It is known as 130 N. How come?

Here’s the reason according to Jose Reyes of SCHMETZ USA:

Years ago … many years ago …

Domestic machines were sold to customers with two common systems, 130 or 705. Mechanically, these old machines were sold with Rotary Hooks, Shuttle Hooks, or Shuttles. Due to these three differences on the hooks, the point of the old needle and the scarf of the old needle had to be manufactured with different specs. Indeed, these two systems were very similar, but not the same. Years later, sewing machine changes and design forced a unification of these two needle systems.

Today, modern sewing machine are sold with new rotary hooks or a modified shuttle hook, making these differences on the needles not necessary, or critical, to the sewing operation.

The new unified system takes in consideration both old systems (130 & 705), and takes the best specs from both needles to form a new one. This new needle is capable of working with new machines as well with some old machines. The new needle system is called “Universal” or “130/705 H.”  The “H,” in the new system,  indicates that these needles have a flat on the shank.

So, back to the “130 N.” This is an old designation from the system “130.” It has a shorter point and an oversized eye, and is capable of working well in both machines, old and new.

So . . . now you know.

 

Needle Eye Comparison

That’s not just a little piece of steel making your machine stitches. German engineering designs, calculates, tests and inspects the SCHMETZ needle. Take for instance the eye, did you know that needles have different eye shapes?

Needle Eye Comparison

The most popular needle, the Universal, has an eye that is 40% the width of the blade. Really! There are three other needles with larger eyes, the Embroidery and even more pronounced is the elongated eye of the Metallic and Topstitch needles.

Now what does a larger eye mean? There is less friction on the thread as it passes through the eye. Ever sew with a thread that breaks or tends to shred? Guess what, use a needle with a larger eye. If you have old thread or maybe a poor quality thread, use a needle with a larger eye. The thread and needle work hard and fast. Help them out when you can with a larger eye.

The Topstitch needle has an extra-long eye that allows the use of heavy,
multiple or poor quality threads. Combine the Topstitch needle with a
straight stitch plate to achieve perfectly straight stitches.

Sizes:  80/12, 90/14, 100/16

Serger Needles

Serger NeedlesConsult your owner’s manual!  Many new sergers use home sewing needle system 130/705 H (flat shank with a scarf). SCHMETZ Stretch, Jersey, Topstitch and Universal are popular needle choices. Some older sergers use needle systems BLX1 and DCX1.

SCHMETZ Overlock Needles

ELx705, ELx705CF and ELx705CF SUK are popular needle systems.  Check your owner’s manual! Here’s how these needles are different from our home sewing needles:

  • Needles have a groove on the front and back sides of the blade to reduce skipped stitches.  The second long groove is necessary to create chain stitches like overlock or coverlock stitches.
  • ELx705, ELx705CF and ELx705CF SUK have increased strength due to a reinforced blade leading to less needle breakage and straighter stitches.
  • ELx705 and ELx705CF have a slightly rounded point for universal use.
  • ELx705CF SUK has a medium ball point suitable for many knit fabrics.
  • ELx705CF and ELx705CF SUK have a Chrome Finish (CF), increasing wear resistance.

Check your owner’s manual!  SCHMETZ ELx705, ELx705CF and ELx705CF SUK are used on overlock or coverlock machines.
