FrogNog 1 #1 December 20, 2005 Is there a method to the madness of needle system numbering? For example, here is a quote from the web: Quote System 16x231 is generally used in single needle lockstitch industrial sewing machines. It is also known as 16x257, 1738, 2270, DBx1, and DBx257; and in sizes 9 through 18 only as 16x95, 287WH, 1738A, and 1738AK Why are there ten codes to refer to one needle system? Why do four of the codes refer to the "same system" but have a more limited needle size envelope? Do the different system codes differ very slightly in required needle geometry (such as the scarf), and the needle makers pick up the slack by making needles that will successfully overlap a number of needle systems? -=-=-=-=- Pull.

masterrigger1 2 #2 December 21, 2005 There are numerous numbering systems out there because each manufacturer wanted to sell replacement needles. I can think of about ten different systems out there. You can buy a code book from Honeycutt & Co. It will give you all of the answers to your questions. Quote System 16x231 is generally used in single needle lockstitch industrial sewing machines.

It is pretty weird! 1.64 mm, 1.90mm, and 2.02mm MELSkyworks Parachute Service, LLC www.Skyworksparachuteservice.com Quote Share this post Link to post Share on other sites
