Round Braid
A braiding machine is a device that interlaces three or more strands of yarn or wire to create a variety of materials, including rope, reinforced hose, covered power cords, and some types of lace. Braiding materials include natural and synthetic yarns, metal wires, leather tapes, and others. Process #Fibers are spun into yarn. #One or more yarns are twisted together to form a strand. #Strands are wound onto bobbins. #Bobbins are mounted on carriers. #Carriers are mounted onto a braiding machine, where the braiding takes place. Horn gear braider In a horn gear braider, bobbins of thread pass one another to the left and right on pseudo-sinusoidal tracks. The bobbins are mounted on spool carriers that are driven by a series of ''horn gears''. A horn gear is a notched disk driven by a spur gear below on the same shaft; bobbins are transferred between notches of adjacent gears. These gears lie below the track plate that the bobbin carriers ride on. The gears must be driven at multipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maypole Dancing In Cape Town
A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place. The festivals may occur on 1 May or Pentecost (Whitsun), although in some countries it is instead erected during Midsummer (20–26 June). In some cases, the maypole is a permanent feature that is only utilized during the festival, although in other cases it is erected specifically for the purpose before being taken down again. Primarily found within the nations of Germanic Europe and the neighboring areas which they have influenced, its origins remain unknown. It has often been speculated that the maypole originally had some importance in the Germanic paganism of Iron Age and early Medieval cultures and that the tradition survived Christianisation, albeit losing any original meaning that it had. It has been a recorded practice in many parts of Europe throughout the Medieval and Early Modern periods, although it became less popular in the 18th a ...

Mass
Mass is an Intrinsic and extrinsic properties, intrinsic property of a physical body, body. It was traditionally believed to be related to the physical quantity, quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particle, elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple Mass in special relativity, definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure (mathematics), measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the Force, strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is Mass versus weight, not the same as weight, even though mass is often determined by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serpentine Shape
A serpentine shape is any of certain curved shapes of an object or design, which are suggestive of the shape of a snake (the adjective "serpentine" is derived from the word ''serpent''). Serpentine shapes occur in architecture, in furniture, and in mathematics. In architecture and urban design The serpentine shape is observed in many architectural settings. It may provide strength, as in serpentine walls, it may allow the facade of a building to face in multiple directions, or it may be chosen for purely aesthetic reasons. *At the University of Virginia, serpentine walls (crinkle crankle walls) extend down the length of the main lawn at the University of Virginia and flank both sides of the rotunda. They are one of the many structures Thomas Jefferson created that combine aesthetics with utility. The sinusoidal path of the wall provides strength against toppling over, allowing the wall to be only a single brick thick. *At the Massachusetts Institute of Technology, the List of ...

Braiding Machine Patent
A braid (also referred to as a plait; ) is a complex structure or pattern formed by interlacing three or more strands of flexible material such as textile yarns, wire, or hair. The simplest and most common version is a flat, solid, three-stranded structure. More complex patterns can be constructed from an arbitrary number of strands to create a wider range of structures (such as a fishtail braid, a five-stranded braid, rope braid, a French braid and a waterfall braid). The structure is usually long and narrow with each component strand functionally equivalent in zigzagging forward through the overlapping mass of the others. It can be compared with the process of weaving, which usually involves two separate perpendicular groups of strands (warp and weft). Historically, the materials used have depended on the indigenous plants and animals available in the local area. During the Industrial Revolution, mechanized braiding equipment was invented to increase production. The braiding t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rickrack
Rickrack (also ricrac and variants of both with a space or hyphen) is a flat piece of braided trim (sewing), trim, shaped like a zigzag. It is used as a decorative element in clothes or curtains. Before the prevalence of sewing machines and overlockers, rickrack was used to provide a finished edge to fabric, and its popularity was in part due to its sturdiness and ability to stand up to harsh washing conditions. Rickrack is produced using a variety of fibers, including cotton, polyester, wool, and metallic fibers, and is sold in a variety of sizes and colors. Invented in the mid-19th century, it took its modern form and current name around 1880. Rickrack's popularity peaked in the 1970s and is associated with the ''Little House on the Prairie (TV series), Little House on the Prairie''. Several designs of formal and up-market girls' dresses with it on as a decoration became popular in the 1950s and 1960s. Some modern sewing machine companies use the name "rickrack stitch" for a ...

Animation Of The Smallest Braiding Machine With Three Carriers And Two Horn Gears
Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognised as an artistic medium, specifically within the entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms. Animation is contrasted with live action, although the two do not exist in isolation. Many moviemakers have produced films that are a hybrid of the two. As CGI increasingly approximates photographic imagery, filmmakers can easily composite 3D animations into their film rather than using practical effects for showy visual effects (VFX). General overview Computer animation can be very detailed 3D animation, while 2D computer an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is usually not triangular. Instead of being straight (as in a triangle) the sides of the cross section have a curved form (usually involute and less commonly cycloidal) to achieve a constant drive ratio. Spur gears mesh together correctly only if fitted to parallel shafts. No axial thrust is created by the tooth loads. Spur gears are excellent at moderate speeds but tend to be noisy at high speeds. Spur gear can be classified into two pressure angles, 20° being the current industry standard and 14½° being the former (often found in older equipment). Spur gear teeth are manufactured as either involute In mathematics, an involute (also known as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
