How do the pins work in Jacquard?
When a card is pushed towards a matrix of pins in the Jacquard mechanism, the pins pass through the punched holes, and hooks are activated to raise their warp threads. Where there are no holes the pins press against the card, stopping the corresponding hooks from raising their threads.
What is the process of weaving fabric on a loom?
To weave fabric on a loom, a thread (called the weft) is passed over and under a set of threads (called the warp). It is this interlacing of threads at right angles to each other that forms cloth. The particular order in which the weft passes over and under the warp threads determines the pattern that is woven into the fabric.
How are cards fed on a loom?
The cards, each with their own combination of punched holes corresponding to the part of the pattern they represent, are then laced together, ready to be fed one by one through the Jacquard mechanism fitted at the top of the loom.

Much like early computers, which used punch cards to store information, the Jacquard loom uses punch cards to store a wea ving pattern, which can then be replicated many times. To program the loom, a designer first draws their pattern onto grid paper. This pattern is then transferred onto punch cards, with an empty grid square corresponding ...
When was the Jacquard loom invented?
Designed in 1805, the Jacquard loom was capable of weaving incredibly complex and detailed patterns in a fraction of the time that a manual master weaver would take to create the same product.
Why did weavers throw shoes into looms?
Master weavers in the early 1800s took many years to learn their trade, and many were angry at being replaced by a machine that could do the job more efficiently. As an act of protest, weavers began removing their shoes and throwing them into the looms, breaking the threads and rendering the looms temporarily useless.
How did the Jacquard loom work?
The Jacquard loom, in contrast, was controlled by a chain of punch cards laced together in a sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Chains of cards allowed sequences of any length to be constructed, not limited by the cards’ size.
How many people were needed to make a loom?
At that time, two people were needed on each loom. A skilled weaver and an assistant, or draw boy, chose by hand which warps (the lengthwise threads held under tension on the loom) to pull up so the weft (the thread inserted at right angles) could be pulled through the warps to create a pattern.
What did Jacquard do in 1801?
At an industrial exhibition in Paris in 1801, Jacquard demonstrated something truly remarkable: a loom in which a series of cards with punched holes ( one card for each row of the design) automatically created complex textile patterns. The draw boy was no longer needed. Patterns that had been painstaking to produce and prone to error could now be mass-produced quickly and flawlessly, once programmed and punched on the cards.

Did Jacquard get a pension?
The government of France soon nationalized the loom (or considered it government property) and compensated Jacquard with a pension to support him while he continued to innovate. He also was paid a royalty for each machine sold. It took Jacquard several more years to perfect the device and make it commercially successful.
What was the purpose of the Jacquard loom?
Jacquard’s loom used plates with holes punched in them to select which hooks could pop up to grab a strand of silk, and which ones were blocked for a given row. The plates were strung together like rungs on a ladder. (You can see them at the top of the loom in the picture).
Where is the silk weaving center in Lyon?
We’re in Lyon, near the Croix Rousse district – the silk-weaving center of old Lyon. You remember from last time who lived here – the Canuts. At the turn of the 19th century, things in this area were changing fast. Joseph Marie Jacquard had just invented his loom, which would revolutionize the textile industry. On one hand, it was just a loom, but on the other hand, it was one of those inventions like the printing press that really changed things.
Who invented the loom?

Why are punched cards important?
The importance of punched cards in weaving can hardly be oversated. Prior to their introduction, a loom would have to be built (or configured or modifed) for each specific textile pattern, whereas with punched-card control, the same loom could produce an unlimited number of patterns simply feeding it different cards.
Who was the first programmer to use punched cards?

What is a jacquard loom?
The Jacquard machine ( French: [ʒakaʁ]) is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom.
When was the first Jacquard loom invented?
The first prototype of a Jacquard-type loom was made in the second half of the 15th century by an Italian weaver from Calabria, Jean le Calabrais, who was invited to Lyon by Louis XI. He introduced a new kind of machine which was able to work the yarns faster and more precisely.
What did Joseph Marie Jacquard do?
Joseph Marie Jacquard saw that a mechanism could be developed for the production of sophisticated patterns. He possibly combined mechanical elements of other inventors, but certainly innovated. His machine was generally similar to Vaucanson 's arrangement, but he made use of Jean-Baptiste Falcon's individual pasteboard cards and his square prism (or card "cylinder"): he is credited with having fully perforated each of its four sides, replacing Vaucanson's perforated "barrel". Jacquard's machine contained eight rows of needles and uprights, where Vaucanson had a double row. This modification enabled him to increase the figuring capacity of the machine. In his first machine, he supported the harness by knotted cords, which he elevated by a single trap board.
Why is jacquard so expensive?
A factory must choose looms and shedding mechanisms to suit its commercial requirements. As a rule the more warp control required the greater the expense. So it is not economical to purchase Jacquard machines if one can make do with a dobby mechanism. As well as the capital expense, the Jacquard machines are more costly to maintain, as they are complex and require higher skilled personnel; an expensive design system is required to prepare the designs for the loom, and possibly a card-cutting machine. Weaving is more costly since Jacquard mechanisms are more likely to produce faults than dobby or cam shedding. Also, the looms will not run as quickly and down-time will increase because it takes time to change the continuous chain of cards when a design changes. For these reasons it is best to weave larger batches with mechanical Jacquards.
When was the first electronic jacquard made?
Bonas Textile Machinery NV launched the first successful electronic Jacquard at ITMA Milan in 1983. Although the machines were initially small, modern technology has allowed Jacquard machine capacity to increase significantly, and single end warp control can extend to more than 10,000 warp ends. That avoids the need for repeats and symmetrical designs and allows almost infinite versatility. The computer-controlled machines significantly reduce the down time associated with changing punched paper designs, thus allowing smaller batch sizes. However, electronic Jacquards are costly and may not be required in a factory weaving large batch sizes, and smaller designs. The larger machines allowing single end warp control are very expensive, and can only be justified where great versatility is required, or very specialized design requirements need to be met. For example, they are an ideal tool to increase the ability and stretch the versatility of the niche linen Jacquard weavers who remain active in Europe and the West, while most of the large batch commodity weaving has moved to low cost areas.
How many rows of needles did Jacquard use?
Jacquard's machine contained eight rows of needles and uprights, where Vaucanson had a double row. This modification enabled him to increase the figuring capacity of the machine. In his first machine, he supported the harness by knotted cords, which he elevated by a single trap board.
What are the advantages of Jacquard?
One of the chief advantages claimed for the Jacquard machine was that unlike previous damask-weaving machines, in which the figuring shed was usually drawn once for every four shots, with the new apparatus, it could be drawn on every shot, thus producing a fabric with greater definition of outline.
