The YKK Group is a Japanese group of manufacturing companies. As the world's largest zipper manufacturer, YKK Group is most known for making zippers; however, it also manufactures other fastening products, architectural products, plastic hardware and industrial machinery.
A zipper, zip, fly, dingy, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding the edges of an opening of fabric or other flexible material, such as on a garment or a bag. It is used in clothing, luggage and other bags, sporting goods, camping gear, and other items. Zippers come in all different sizes, shapes, and colors. Whitcomb L. Judson, who was an American inventor from Chicago, is sometimes given credit as the inventor of the zipper, but he never made a practical device. The method, still in use today, is based on interlocking teeth. Initially, it was titled the "hookless fastener" and was later redesigned to become more reliable.
In modern clothing and fashion design, a button is a small fastener, now most commonly made of plastic but also may be made of metal, wood, or seashell, that joins two pieces of fabric together. In archaeology, a button can be a significant artifact. In the applied arts and in craft, a button can be an example of folk art, studio craft, or even a miniature work of art.
A wallet is a small, flat case that can be used to carry such small personal items as cash, credit cards, and identification documents, photographs, transit pass, gift cards, business cards and other paper or laminated cards. Wallets are generally made of leather or fabrics, and they are usually pocket-sized but not always foldable. Wallets may have features such as money clips; chain fastener, strap, or rein; or a zipper. Specialized wallets are designed for holding passports, wearable ID cards, and checkbooks, to give some examples. Some unusual wallets are worn on the wrist or shoe. In addition to their practical function, wallets may be used as a fashion accessory, or to demonstrate the style, wealth, or status of the owner.
The buckle or clasp is a device used for fastening two loose ends, with one end attached to it and the other held by a catch in a secure but adjustable manner. Often taken for granted, the invention of the buckle was indispensable in securing two ends before the invention of the zipper. The basic buckle frame comes in a variety of shapes and sizes depending on the intended use and fashion of the era. Buckles are as much in use today as they have been in the past: used for much more than just securing ones belt, instead they are one of the most dependable devices in securing a range of items.
Gideon Sundback was a Swedish-American electrical engineer, who is most commonly associated with his work in the development of the zipper.
A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Welding is an example of creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.
Whitcomb L. Judson was an American machine salesman, mechanical engineer and inventor. Judson invented the zipper in the 1890s.
In metalworking, a drift pin, drift pin punch, slave pin, simply drift, or even pokey bit is the name for a tool used for enlarging holes, or aligning holes prior to bolting or riveting metal parts together. A drift pin is not used as a punch in the traditional sense of the term. A drift is constructed as a tapered rod, with the hammer acting on the large end of the taper. The tapered end of a drift punch is placed into the semi-aligned bolt holes of two separate components, and then driven into the hole. As it is driven in, the taper forces the two components into alignment, allowing for easy insertion of the fastener. Unlike most punches, force should never be applied to the tip of drift pin.
A belt buckle is a buckle, a clasp for fastening two ends, such as of straps or a belt, in which a device attached to one of the ends is fitted or coupled to the other. The word enters Middle English via Old French and the Latin buccula or "cheek-strap," as for a helmet. Belt buckles and other fixtures are used on a variety of belts, including cingula, baltea, baldrics and later waist-belts.
The Colt Model 1903 Pocket Hammerless is a .32 ACP caliber, self-loading, semi-automatic pistol designed by John Browning and built by Colt Patent Firearms Manufacturing Company of Hartford, Connecticut. The Colt Model 1908 Pocket Hammerless is a variant introduced five years later in .380 ACP caliber. Despite the title "hammerless", the Model 1903 does have a hammer. The hammer is covered and hidden from view under the rear of the slide. This allows the pistol to be carried in and withdrawn from a pocket quickly and smoothly without snagging.
An impact wrench is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft.
Talon Zipper is a company founded in 1893, originally as the Universal Fastener Company, in Chicago. They later moved to Hoboken, New Jersey, and finally to Meadville, Pennsylvania. It was in Meadville that the zipper as we know it was invented, until then they were producing hookless fasteners for boots and shoes. Here, the zipper was mass-produced beginning in the 1920s. The high demand for zippers created favorable conditions for the Talon Company, and so became Meadville's most crucial industry. The company encountered significant difficulties after it was absorbed by Textron industries in 1968, eventually ending up bankrupt. Today, nothing remains of Talon in Meadville except for a few run down buildings. However, as a result of the need for close tolerances and tool and die makers, a cottage industry of tool and die shops was established which resulted in Meadville being nicknamed Tool City with more tool shops per capita than any place else in the United States. Other early names included the Automatic Hook and Eye Company, and the Hookless Fastener Company.
A lapel pin, also known as an enamel pin, is a small pin worn on clothing, often on the lapel of a jacket, attached to a bag, or displayed on a piece of fabric. Lapel pins can be ornamental or can indicate wearer's affiliation with an organization or cause. Before the popularity of wearing lapel pins, boutonnières were worn.
A punch is a hard metal rod with a sharp tip at one end and a blunt butt end at the other, which is usually struck by a hammer. Typically, woodworkers use a ball-peen hammer to strike a punch.
Sewing is the craft of fastening or attaching objects using stitches made with needle and thread. Sewing is one of the oldest of the textile arts, arising the in Paleolithic Era. Although usually associated with clothing and household linens, sewing is used in a variety of crafts and industries, including shoemaking, upholstery, sailmaking, bookbinding and the manufacturing of some kinds of sporting goods. Sewing is the fundamental process underlying a variety of textile arts and crafts, including embroidery, tapestry, quilting, appliqué and patchwork.
Resealable packaging is any type of packaging that allows the consumer or user to reseal or reclose the packaging. Often packaging needs to be resealed in order to maintain product freshness or prevent spillage. Reusable packaging allows for multiple uses which can help reduce waste.
String is a long flexible structure made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago. In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys.
Coil zipper—also known as nylon coil zipper—is a type of zipper whose teeth/elements are made from coiled monofilament that is traditionally nylon. The coil is sewn to a zipper tape to make the final product. The final zipper product is completed when the nylon coiled teeth are sewn onto the zipper tape. Nylon coil zippers have a continuous coil chain made from nylon. When this coil is positioned on the back of the zipper and not in the front, this kind of zipper is called invisible zipper.
