Schwabe's box loom
A shuttle loom without automatic filling transfer can not be classified as automatic.
To move the shuttle box up and down in order to bring the right shuttle to the picking level, a box motion is used.
The shuttle flies back and forth on the loom.
Single or multiple gripper or projectile looms, rapier looms,water jet looms and air jet looms.
The shuttle looms have a wide degree of versatility and fall into three main classes
The mass of the reciprocating parts is small compared with that of the sley in a shuttle loom.
The projectile loom uses a small projectile to carry the filling yarn through the shed.
As the rapier head traverses the loom, it is allowed to rest on the raceboard, which is much reduced in dimensions from that found on a shuttle loom.

The result is that usually the warp shed must be larger than that for a shuttle loom.
The projectile loom uses a projectile with grippers to carry the yarn through the shed.
Thus these looms can be run faster than conventional shuttle looms. Also the acceleration of the projectile can exceed that of a shuttle by a factor of about7.
If more than one color is needed in the filling, then a number of shuttles and shuttle boxes will have to be used.
A shuttle loom has two cam operated picking mechanisms, one on either side, each of which operates every other weaving cycle.
