Weaving loom

loom around 1568

a weaving loom (regionally also called loom) is an advancement of the loom and serves the industriellen production of fabrics.

On weaving looms chaining threads are led forward by the rear side of the machine. Schussfäden become in each case from a side to the other onebetween the chaining threads through-shot, so that the chaining threads are held together with the finished fabric by the Schussfaden. Around this Durchschiessen a part of the chaining threads will make possible lifted and the other part lowered. Thus an opening develops, by which the Schussfaden can be pulled through. ThisOne calls opening the subject. The thread can be accomplished thereby in different kind. The oldest form is thereby the contactors for which a Garnspule carries and is through-hurled by the subject. There are also weaving looms, where the Schussfaden with a fine air orWater jet is blown through by a side, through-shot with a projectile or through-handed by two grip arms by the subject (z. B. Sulzer Textile's G6500). With narrow volumes the thread with a needle can be through-threaded and be become on the other page hooking ELT.

Modern weaving looms possessseveral fan (z. B. Sulzer Textile's M8300), so that several Schussfäden can be shot at the same time through, in order to increase the productivity. Thus are possible on such weaving looms up to 5000 m/min firing entry.

The used procedure depends on the width the produced fabric. Are possiblenarrow volume weaving looms to broad fabrics to ten meters and more.

From different lifting and lowering of the threads the connection of the fabric results. With simple fabrics frameworks, shanks so mentioned on the front , are where in each case a part of the chaining threads abbewegt by braids up andbecome. These shanks are moved off by eccentric cams on and. With more complicated fabrics the Jacquardmaschine is used, where each chaining thread can be lifted and/or lowered individually. Today the controlling of the Jaquardmaschinen takes place naturally all-electronically.

So that the fabric becomes not too loose, strikes each time, if noneSchussfaden in the subject is, a Web sheet, Web comb or guessed the fabric together.

In these fabrics rubber threads can be trained also in the longitudinal direction of thread, so that the fabric is flexible. In addition the rubber threads, which umsponnen either naked or with other threads be can, must instretched condition to be processed. In addition, the flexible effect is reached through textured yarns so mentioned, which are flexible up to a certain degree also.

Particularly the volume weaving looms replaced the braiding machine by their technical progress in examination and speed, very strongly.

History

of looms are already from the Neolithikum admits and belong thereby to the oldest machines of mankind.

The first weaving looms were the volume mills in such a way specified, with their assistance in 16. Century of volumes were manufactured.

The oldest draft of a mechanical loom comes from 1678, camebut never for the execution.

1728 used a silk weber from Lyon punched Holzbrettchen for controlling of its looms. Jacques de Vaucanson from Grenoble continued to develop this simple loom to one mechanically by a wooden punch card steered model (1745). With this automat it was for the first time possible,to manufacture examined materials. Unfortunately however the equipment came over the status prototypes out and never industrially was never used. Nearly at the same time, i.e. 1733 invented John Kay Schnellschützen, which doubled the Web speed.

If these looms were still hand-operated, then Vaucanson found a possibility,that one could operate it with a Göpel by a horse or by a donkey. The sample was produced by a cam roller.

Jacquard loom

1785 invented Edmond Cartwright the full-mechanized loom with the names power Loom. A great many jobs were destroyed by this technology. AsConsequence came it to the Maschinenstürmerei and many looms was destroyed. In particular the schlesische weber rebellion of 1844 clarified the social misery in the coming down family handicraft.

Joseph Marie Jacquard from Lyon improved the machine 1805 crucially, by building Vaucansons control engineering into Cartwrights machines. From now on playedthe weaving loom a crucial role in the textile industry and the industriellen revolution. The first steam-claimant weaving loom became in the centralEnglish Bradford toward end 19. Century assigned.

Not least the invention of the weaving loom caused the fear, technical progress to mass unemployment would in the long term lead. Thisstill fear represented by Ricardo and Marx was recognized however by the economic theory in the meantime as implausible (see. technical progress).

These punch card looms were not only one of the most important contributions for industrialization, but also the foundation-stone for the development of control engineering.

Beside the spin machine was thoseInvention of the weaving loom of one of the most important milestones of the industriellen revolution. By it the production conditions changed crucially and former home-worker inside had from now on as factory hand inside getting along to create itself.

Weaving looms changed however not only the social reality of humans, but also the products themselves: Thoseorganization art-relating to crafts was replaced through technically perfect samples. Exclusive Luxusartikel became civil consumer goods and mass-produced goods.

A well-known Bandwirkermuseum still is in Wuppertal Ronsdorf. One can recognize well, how in former times the first machines worked.
