Paper Cutter
A paper cutter, also known as a paper guillotine or simply a guillotine, is a tool often found in offices and classrooms, designed to administer straight cuts to single sheets or large stacks of paper at once. History Paper cutters were developed and patented in 1844 by French inventor Guillaume Massiquot. Later, Milton Bradley went on to patent his own version of the paper cutter in 1879. Since the middle of the 19th century, considerable improvements to the paper cutter have been made by Fomm and Krause of Germany, Furnival in England, and Oswego and Seybold in the United States. Description Paper cutters vary in size, usually from about in length on each side for office work to (an edge of A1 paper) in design workshops. The surface will typically have a grid either painted or inscribed on it and may have a ruler across the top. At the very least, it must have a flat edge against which the user may line up the paper at right angles before passing it under the blade. It ...

Paper Cutter 1
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although th ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scissors
Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats. Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles. Terminology The ...

Board Shear
Used extensively in bookbinding, a board shear is a large, hand-operated machine for cutting board or paper. Like scissors, a board shear uses two blades to apply shear stress exceeding the paper's shear strength in order to cut. The stationary blade forms the edge of the cutting table, with the moving blade mounted on a cutting arm. Originally known as a table gauge shear because its gauge allowed the cutting of consistently-sized materials, the board shear resembles a larger version of the paper cutters commonly found in offices. The earliest known reference to a board shear comes from an 1842 supplement to ''Penny Magazine'', titled ''A Day at a Bookbinder's'', which included a drawing of a board shear with many of the major developments already present. An 1854 article on the history of bookbinding from ''The Bookbinder's Trade Circular'' describes early board shears, and places their development in "about 1836"; credit for the invention is ascribed to Warren De La Rue in ...

Vinyl Cutter
A vinyl cutter is an entry level machine for making signs. Computer designed vector files with patterns and letters are directly cut on the roll of vinyl which is mounted and fed into the vinyl cutter through USB or serial cable. Vinyl cutters are mainly used to make signs, banners and advertisements. Advertisements seen on automobiles and vans are often made with vinyl cut letters. While these machines were designed for cutting vinyl, they can also cut through computer and specialty papers, as well as thicker items like thin sheets of magnet. In addition to sign business, vinyl cutters are commonly used for apparel decoration. To decorate apparel, a vector design needs to be cut in mirror image, weeded, and then heat applied using a commercial heat press or a hand iron for home use. Some businesses use their vinyl cutter to produce both signs and custom apparel. Many crafters also have vinyl cutters for home use. These require little maintenance and the vinyl can be bought in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penknife
Penknife, or pen knife, is a British English term for a small folding knife. Today the word ''penknife'' is the common British English term for both a pocketknife, which can have single or multiple blades, and for multi-tools, with additional tools incorporated into the design. Originally, penknives were used for thinning and pointing quills (cf. ''penna'', Latin for ''feather'') to prepare them for use as dip pens and, later, for repairing or re-pointing the nib. A penknife might also be used to sharpen a pencil, prior to the invention of the pencil sharpener. In the mid-1800s, penknives were necessary to slice the uncut edges of newspapers and books. A penknife did not necessarily have a folding blade, but might resemble a scalpel or chisel by having a short, fixed blade at the end of a long handle. One popular (but incorrect) folk etymology makes an association between the size of a penknife and that of a small ballpoint pen. During the 20th century there has been a proli ...

Coil Spring
A selection of conical coil springs The most common type of spring is the coil spring, which is made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae - the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs. Coil springs can be either compression springs, tension springs or torsion springs, depending on how they are wound. A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. They are commonly used in mattresses, automotive suspensions, and residential plumbing. Coil springs come in a variety of sizes and shapes and can be used for a variety of applications. Small coil springs are often us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruler
A ruler, sometimes called a rule, line gauge, or scale, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines. Variants Rulers have long been made from different materials and in multiple sizes. Some are wooden. Plastics have also been used since they were invented; they can be molded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting. in length is useful for a ruler to be kept on a desk to help in drawing. Shorter rulers are convenient for keeping in a pocket. Longer rulers, e.g., , are necessary in some cases. Rigid wooden or plastic yardsticks, 1 yard long, and meter sticks, 1 meter long, are also used. Classically, long measuring rods were used for larger projects, now superseded by ...

ISO 216
ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America. The standard defines the "A", "B" and "C" series of paper sizes, including A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes. All ISO 216, ISO 217 and ISO 269 paper sizes (except some envelopes) have the same aspect ratio, , within rounding to millimetres. This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio. Each ISO paper size is one half of the area of the next larger size in the same series. Dimensions of A, B and C series History The oldest known mention of the advantages of basing a paper size on an aspect ratio of is found in a letter written on 25 October 1786 by the German scientist Georg Christoph Lichtenberg ...

Milton Bradley
Milton Bradley (November 8, 1836 – May 30, 1911) was an American business magnate, game pioneer and publisher, credited by many with launching the board game industry, with his eponymous enterprise, which was purchased by Hasbro in 1984, and folded in 1998. Biography Born in Vienna, Maine, in 1836, to Lewis and Fannie (Lyford) Bradley, Bradley grew up in a working class household. The family moved to Lowell, Massachusetts, in 1847. After completing high school in 1854, he found work as a draftsman and patent agent before enrolling at the Lawrence Scientific School in Cambridge, Massachusetts. He was unable to finish his studies after moving with his family to Hartford, Connecticut, where he could not find gainful employment. In 1856, Bradley moved to Springfield, Massachusetts, where he worked as a mechanical draftsman. In 1859, Bradley went to Providence, Rhode Island, to learn lithography; and, in 1860, he set up the first color lithography shop in Springfield, Massachus ...
