CNC-ANK001 - DOUBLE ZIPPER

Dr. Elias Howe, who invented the sewing machine, received a patent in 1851 for an “Automatic, Continuous Clothing Closure”.  Perhaps it was the success of his sewing machine and thus Howe missed his chance to become the recognized ‘Father of the Zip.’

About 42 years later (year 1893) when it was a time of lacing boots and fastening high button shoes. To remove the tedium, to speed things up, Whitcomb L. Judson was inspired to invent 2 thin metal chains that could be fastened together by pulling a slider up between them. He patented this “clasp locker or unlocker for shoes.”

Gideon Sundback made several advances in the development of the zipper between 1906 and 1914. The patent for the “Separable Fastener” was issued in 1917.

The name zipper was created in 1923 by B.F. Goodrich, who used the device on their new boots. Initially, boots and tobacco pouches were the primary use for zippers; it took another twenty years before they caught on in the fashion industry. About the time of World War II the zipper achieved wide acceptance for the flies of trousers and the plackets of skirts and dresses.

A zipper costs relatively little, but if it fails, the garment may be unusable until the zipper is repaired or replaced—which can be quite difficult and expensive. Problems often lie with the zipper slider; when it becomes worn it does not properly align and join the alternating teeth. If a zipper fails, it can either jam (i.e. get stuck) or partially break off.

Zipper Types

  • Coil zippers  – The slider runs on two coils on each side; the “teeth” are formed by the windings of the coils.
  • Invisible zippers – They have the teeth hidden behind a tape, so that the zipper is “invisible”.
  • Metallic zippers – They are the classic zipper type, found mostly in jeans today.
  • Plastic-molded zippers – They are identical to metallic zippers, except that the teeth are plastic instead of metal.
  • Open-ended zippers – They use a “box and pin” mechanism to lock the two sides of the zipper into place, often in jackets.
  • Closed-ended zippers – They are closed at both ends; they are often used in luggage.

Last but not least,

  • Zip –  A  file format used for data compression and archiving.

THE MONOLOGUE OF A ZIPPER

Hi, my name is Zipper.

My friends love calling me Zip in short.

To be frank, I hate it whenever they call me by that name.

I am more of the artistic type and always mingle with fabrics, leathers and other lovely and wonderful fashion-related materials.

And for the last time…

I KNOW NOTHING ABOUT DATA COMPRESSION OR ARCHIVING!!

So, to all my wonderful friends out there…

PLEASE STOP CALLING ME ZIP!

Oh… did I just shout out loud twice???

Any inappropriate behaviour is much regretted.

Have a nice day. 

Have fun reading!

Cheers & TTFN~ 😀
