Welt (shoe)
A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The basic principle behind the Goodyear welt machine was invented in 1862 by Auguste Destouy, who designed a machine with a curved needle to stitch turned shoes. The machine was then improved in 1869 and later by Destouy and, more importantly, Daniel Mills, an English mechanic, both employed by Charles Goodyear Jr., the son of Charles Goodyear. It has been noted by historians that Goodyear was a frequent visitor to the shoe factory of William J. Dudley, founder of Johnston & Murphy, where early work on sole stitching equipment was performed. Construction "Goodyear construction" involves stitching a welt to the upper and insole of a shoe. The welt is connected to both the upper and insole with thread by means of a raised ridge around the bottom outside edge of the insole, usually reinforced with a canvas-like "rib" (known as "gemming") which is cemented to the back of the ri ...

Leather
Leather is a strong, flexible and durable material obtained from the tanning (leather), tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, ostriches, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Critics of tanneries claim that they engage in unsustainable practices that pose health hazards to the people and the environment near them. Production processes The leather manufacturing process is divided into three fundamental subprocesses: preparatory stages, tanning, and crusting. A further subprocess, finishing, can be added into the leather process sequence, but not all leathers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...

Shoe
A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function, but over time, shoes also became fashion items. Some shoes are worn as safety equipment, such as Steel-toe boot, steel-toe boots, which are required footwear at industrial worksites. Additionally, shoes have often evolved into many different designs; High-heeled shoe, high heels, for instance, are most commonly worn by women during fancy occasions. Contemporary footwear varies vastly in style, complexity and cost. Basic sandals may consist of only a thin sole (shoe), sole and simple strap and be sold for a low cost. High fashion shoes made by famous Fashion design, designers may be made of expensive materials, use complex construction and sell for large sums of money. Some shoes are designed for specific purposes, such as boots designed specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Goodyear
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844. Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock. His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire and Rubber Company is named after (though not founded by) him. Early life Charles Goodyear was born on December 29, 1800, in New Haven, Connecticut, the son of Amasa Goodyear, and the oldest of six children. His father was a descenda ...

Cork (material)
Cork is an impermeable buoyant material. It is the phellem layer of bark tissue which is harvested for commercial use primarily from '' Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell. Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork is made up of suberin (average of about 40%), lignin (22%), polysaccharid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last
A last is a mechanical form shaped like a human foot. It is used by shoemakers and cordwainers in the manufacture and repair of shoes. Lasts come in many styles and sizes, depending on the exact job they are designed for. Common variations include simple one-size lasts used for repairing soles and heels, custom-purpose mechanized lasts used in modern mass production, and custom-made lasts used in the making of bespoke footwear. Lasts are made of firm materialshardwoods, cast iron, and high-density plasticsto withstand contact with wetted leather and the strong forces involved in reshaping it. Since the early 19th century, lasts typically come in pairs to match the separate shapes of the right and left feet. The development of an automated lasting machine by the Surinamese-American Jan Ernst Matzeliger in the 1880s was a major development in shoe production, immediately improving quality, halving prices, and eliminating the previous putting-out systems surrounding shoema ...

Contact Cement
Impact glue, contact glue, contact cement, or neoprene glue is a type of solvent-based adhesive which may be used to bond materials such as plastics, laminates, and metal or wood veneers. The term "contact glue" come from the practice of applying adhesive to both surfaces to be bonded; the surfaces are joined once the solvent in the adhesive evaporates, leaving a bond with high shear resistance. Contact adhesives do not exclusively designate neoprene adhesives; all adhesives characterized by high instant adhesion may be considered contact adhesives, but the most common among them are solutions of neoprene or rubber. Properties Impact glue has a high adhesive capacity, and is particularly failure-resistant compared to other non-reactive adhesives when applied correctly. It is typically applied in thin layers on both materials to be joined. Impact adhesives are used frequently with laminates, such as in bonding Formica to countertops, and in footwear, as in attaching outsoles to ...

Raphael Salaman
Raphael Arthur Salaman (24 April 1906 – 31 December 1993) was an English engineer, collector, and writer. His work recorded the hand tools used in Britain during the 18th, 19th and early 20th centuries. Biography Family and education R. A. Salaman, also known as Raph, was born in Barley, Hertfordshire into a well-established Anglo-Jewish family. His father was Dr Redcliffe N. Salaman, the botanist who wrote ''The History and Social Influence of the Potato. ''His mother Nina (''née'' Davis) was a writer, poet and Hebrew scholar who tried to teach him Hebrew, which he found hard unlike his elder brothers. However, being Jewish was still important to Salaman and he used to tell his children about it and read the Bible. The Salaman family were Ashkenazi Jews, who, according to his father, migrated to Britain from either Holland or the Rhineland in the early 18th century. His family were members of Bevis Marks Synagogue. Salaman's interest in tools developed from watc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
