Tufting is a special technique where by a tufting needle in a tufting gun is shot through a fabric by means of compressed air.
On the back of the fabric a loop pile is formed that will be cut by a rotating cutting wheel on the tufting machine.
Later the pile has to be fixed by applying paste to the fabric to secure the threads, because otherwise they could be easily pulled out again. Usually the pasting is done with latex.
In robot tufting the tufting process with the gun and the compressed air is computer operated. The advantage is the regularity and the possibility to vary the height of the pile during the tufting.
pass tuft and machine tuft
In pass tuft and machine tuft a number of tufting needles are in one line and the thread, similar to the manual method, is pierced through a fabric without using compressed air.
