Since the appearance of an umbrella more than 3,000 years ago, the advancement of technology made it possible to make increasingly complex umbrellas. As time goes on, new materials become available, more durable construction, complex moving parts for opening and closing the canopy, and more new additions lead to the umbrella industry. Although the original design of the umbrella of ancient Rome has hardly changed, the modern umbrella is strong and lightweight and protects wearers from rain, snow, wind and sunlight.
Today umbrellas and parasols are used to maintain some models of rain and sun protection for individual movement and stronger fixed use (parasols are more common in this configuration). Since the umbrella can be assembled manually from various components, the basic model should be easy to use, lightweight and strong. The basic components of all umbrellas are as follows.
Awning - Umbrella Awning fabric uses constantly changing cloth. The original popular linen, cotton, leather, and taffeta silk were replaced with glulier (silk and wool, or silk and cotton fabric) and then replaced with ruthen and acetate. However, contemporary umbrellas are using a microfiber fabric (nylon taffeta) coated with a special waterproof finish. Since opening and closing motion of the umbrella requires movement that can not be performed with one piece of fabric, sunshades can not be made with cloth. The machine cuts each part of the canopy (usually eight) and when it is stitched together and attached to the ribs it folds and unfolds neat
Ribs and Stretchers - Fix the canopy in its structure and open and close the canopy. They usually consist of steel or other metal, the most common plastic connector (runner) of the stretcher is attached to the shaft.
Runner - This very important umbrella is responsible for controlling the opening and closing mechanism of the canopy.
Shaft - usually wood, aluminum steel, sometimes made of glass fiber or other plastic. Folding umbrella with movable shaft that can be extended to longer or shorter length
The above process usually continues to make a stick umbrella. There are also collapsible umbrellas, they are manufactured by the same basic techniques, but they are mechanically more complicated than umbrellas. The difference between the two is that when making a folding umbrella, a two piece shaft that itself is a telescope is used. In addition to this, there is an additional set of runners along the top of the umbrella.
A parasol and a parasol are mainly portable type portable equipment and it is suitable for personal use. The biggest portable umbrella is a golf umbrella. Umbrellas can be divided into two categories: fully collapsible umbrella in which the metal rod supporting the shade is small enough to fit in the handbag and a collapsible parasol awning where the support bar can not be retracted Only you can collapse. There is another difference between a manually operated umbrella and a spring-loaded automatic umbrella which jumps when pushing a button.
Umbrella manufacture is basically a manual assembly process, and various components are connected to each other in a structured way. In addition to the fabric canopy, the rest of the umbrella has a shaft, rib, tensioner, slide, handle. They can be made of wood, metal, plastic or other such material. It is usually made of wood, steel or aluminum. Glass fibers and other plastics are sometimes used, and it can usually be seen with larger golf umbrellas. In the case of wood, the shaft is manufactured using a wood molding machine such as a lathe and a lathe. Stretch or extrude the metal shaft and plastic shaft to the desired shape.
