Design and Principle of Weaving Looms

Further principles for carpet manufacturing are presented in Section 4.6.2. 

Warp stoppers are positioned between the warp beam and the shafts. 

The movement of the shafts is generated by cam or shaft machines. The size of the repeat or rapport corresponds to the number of shafts or to a multiple of this number. Wovens with large patterns can be produced with Jacquard machines that allow the individual movement of single warp threads. 

During weft insertion, the reed is positioned at the back dead center while the shed is open. With the change of shed, the reed moves forward to beat the inserted weft thread at the fell of the cloth. 

According to the principle of weft insertion, weaving looms can be divided into shuttle looms (Fig. 4.13), projectile looms, rapier looms, and air-jet looms.
