Looms can be classified as follows depending on whether they use a shuttle or not and the method used to insert the weft yarn.
|Loom type||Method of inserting weft yarn||Characteristics|
|Looms with shuttles||The weft yarn is inserted through the back-and-forth motion of the shuttle.||Great all purpose loom. Vibration and noise are severe problems and high speed operation is difficult.|
|Looms without shuttles||Gripper loom||A small metal gripper shuttle grasps the weft yarn and inserts it.||A very versatile loom, but it is noisy and there is a limit to its operation at high speed.|
|Rapier loom||Two bands at the center of the fabric receive and pass on the weft yarn. The catch method is the most popular method, and is further broken down into two types, the band method and the pole method.||A very versatile loom, but it is noisy and there is a limit to its operation at high speed.|
|Water jet loom||A jet of water is used to insert the weft yarn.||High speed operation is possible. Since water is used only filament yarns (synthetic fabrics) can be woven.|
|Air jet loom
|A jet of air is used to insert the weft yarn.||High speed operation is possible. At present this is the most popular type of loom and its functions are excellent overall.|
