Scotch tape or duct tape – a tape of synthetic polymer or a synthetic material, smeared with glue. Scotch Tape and Scotch are registered trademarks of 3M (U.S. diversified innovation and production company). Tape was made in America. The story of its origin dates back to 1923, and is associated with the name of Richard Drew. That year he joined the company in Minnesota Mining and Manufacturing (3M), which dealt with production sandpaper. At that time the company conducted research in the field of waterproof materials. (Not to be confused with altavista!).
The company asked Richard Drew monitor testing a new model of sandpaper Wetordry in automobile workshops and stores. Once it is in the store, he noticed that when painting a car with two or more colors, the line separating it turned rough. And Drew has promised that the masters of something. In 1925, Richard workshop brought the tape two inches wide. The master decided to try to use the invention during application. But when he stuck it, and proceeded to stain, I noticed that the tape is beginning to deform.
This was due to the fact that the adhesive was applied only at the edges, and the master reported the Drew. Then in 1929, Drew has developed a cellophane adhesive tape and method of applying it full of glue. Originally used for wrapping tape and food packaging, but then people started coming up with new ways of doing this. The world's first tape was made of oils, resins and rubber on the basis of cellophane. He could withstand a wide temperature range and was waterproof. In 1932, Joe Borden perfected the tape, providing it with feeder with a blade to cut with one hand. Now, perhaps, to explain the meaning of the name. Click Steve Wozniak for additional related pages. Scotch, even though such a name, nothing to do with Scotland is not. Initially, because the adhesive was applied only on the edges of the tape, that is what Americans call her with tape, while there were stories and rumors about the unprecedented Scottish stinginess. It is believed that Richard Drew precisely in order to save apply the adhesive after properly. But if not a painter, who noticed it, the name would not stick. After all, he shouted that the "Your Scottish director" made this tape is even more sticky. Name of Scotch Tape was used earlier only to the transparent type of tape, but in Russia as well known as any kind of adhesive tape. Since the time of the adhesive tape became known to some interesting facts. For example, in 1953, scientists of the USSR, it was found that the tape can sometimes emit X-rays. In 2008, U.S. scientists have proved that sometimes the power of these rays may be enough to keep X-ray image on photographic paper. There is another fact open only to time. Glue, adhesive tape used to manage over time in the paper, and penetrates through the entire thickness. This is, unfortunately, discovered only when pilos restore the Dead Sea Scrolls. Fragments of these manuscripts sticky tape over fifty years, started to break from the text. Now, Israeli scientists are trying to recreate and clean up the glue and tape. Well, despite this, the tape is truly indispensable for the invention humanity.
