How does a rapier loom work?
How does a rapier loom work?
A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers. The rapier moves across the width of the fabric, carrying the weft yarn across through the shed to the opposite side.
How does the Northrop loom work?
The principal advantage of the Northrop loom was that it was fully automatic; when a warp thread broke, the loom stopped until it was fixed. When the shuttle ran out of thread, Northrop’s mechanism ejected the depleted pirn and loaded a new full one without stopping.
Who invented the Northrop loom?
James Henry Northrop
He emigrated to Boston, MA, in the USA in 1881. By 1898, working in Hopedale, Massachusetts for George Draper and Sons he had filed several hundred patents some of which were used in the Northrop Loom. He retired at 42….

Was the first computer a loom?
The Jacquard loom is often considered a predecessor to modern computing because its interchangeable punch cards inspired the design of early computers.
Why is the rapier loom a modern loom?
Advantages of Rapier Loom: Over Conventional Loom: Weft insertion rate is very high rather than any conventional loom. It can occur double pick at a time by double picking insertion system. Here is no need to cut the weft selvedges and no weft wastage.
Why is the rapier loom important?
Advantages of a Rapier Loom: Rapier loom is a shuttle less power loom. It weaves more rapidly than other types of shuttle loom. On the other hand, weaving efficiency of rapier loom is less than projectile machine.

What is pit loom?
As the name suggests, ‘Pit Loom’ is a type of loom which is fit in a pit where the artisan makes the rug through the use of pedals, and normally the base of pitloom is more strong than handloom & can go without using latex.
What is Jaguar loom?
Invented by Joseph Jacquard and demonstrated in 1801, the Jacquard Loom is an attachment for powered fabric looms. The Jacquard Loom is important to computer history because it is the first machine to use interchangeable punch cards to instruct a machine to perform automated tasks.
How much did Hollerith sell his company for?
On July 6, 1911, Hollerith agreed to sell his Tabulating Machine Company to financier Charles Flint for US$2,312,100, and the company became part of Flint’s Computing-Tabulating-Recording Company. In the 1920s, C-T-R evolved into IBM. [Read more about the Icon of Progress, The Making of IBM.]
Are looms still used today?
Spools of weft are unravelled as the shuttle travels across the shed. This is very similar to projectile methods of weaving, except that the weft spool is stored on the shuttle. These looms are considered obsolete in modern industrial fabric manufacturing because they can only reach a maximum of 300 picks per minute.
How does a rapier loom work for weaving?
A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers.
What kind of yarn is used in a rapier?
A stationary package of yarn is used to supply the weft yarns in the rapier machine. One end of a rapier, a rod or steel tape, carries the weft yarn. The other end of the rapier is connected to the control system. The rapier moves across the width of the fabric, carrying the weft yarn across through the shed to the opposite side.
How does a rapier work in a shed?
One end of a rapier, a rod or steel tape, carries the weft yarn. The other end of the rapier is connected to the control system. The rapier moves across the width of the fabric, carrying the weft yarn across through the shed to the opposite side. The rapier is then retracted, leaving the new pick in place.
Which is better a double rapier or a single rapier?
One rapier carries the yarn to the centre of the shed, where the opposing rapier picks up the yarn and carries it the remainder of the way across the shed. The double rapier is used more frequently than the single rapier due to its increased pick insertion speed and ability to weave wider widths of fabric.
