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.
