The spinning drive wheel turns the flyer and, via friction with the flyer shaft, the bobbin. A short tension band, or brake band, adds drag to the bobbin such that when the spinner loosens their tension on the newly spun yarn, the bobbin and flyer spin relative to each other and the yarn is wound onto the bobbin.
Spinning is an ancient textile art in which plant, animal or synthetic fibres are drawn out and twisted together to form yarn. For thousands of years, fibre was spun by hand using simple tools, the spindle and distaff. After the introduction of the spinning wheel in the 13th century, the output of individual spinners increased dramatically.
Spin art. Spin art is an art form that uses paint, a canvas such as glossy cardboard and a spinning platform. It is primarily used to entertain and expose children to the process of art creation, although it can be enjoyed by people of all ages.
Lottery machine. A lottery machine is the machine used to draw the winning numbers for a lottery . Early lotteries were done by drawing numbers, or winning tickets, from a container. In the UK, numbers of winning Premium Bonds (which were not strictly a lottery, but very similar in approach) were generated by an electronic machine called ERNIE .
Spinner's weasel (left) and spinning wheel (right) Spinner's weasel or clock reel is a mechanical yarn-measuring device consisting of a spoked wheel with gears attached to a pointer on a marked face (which looks like a clock) and an internal mechanism which makes a "pop" sound after the desired length of yarn is measured (usually a skein). The ...
A worker spinning cotton at a hand-powered spinning wheel in the 18th century would take more than 50,000 hours to spin 100 lb of cotton; by the 1790s, the same quantity could be spun in 300 hours by mule, and with a self-acting mule it could be spun by one worker in just 135 hours. [23]
Newton disc. The Newton disc, also known as the disappearing colour disc, is a well-known physics experiment with a rotating disc with segments in different colours (usually Newton's primary colours: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when ...
Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions. The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly ...
