2.1 Shuttle Looms
The conventional shuttle looms
account for about 85% of the total world loom capacity.
However, in terms of productive performance (m2 /h), the average output of the shuttle weaving machine is twice or even more than that of the conventional shuttle loom.
During 1951-1971, international textile exhibitions were dominated by the shuttle looms.
After 1971, when the shutle looms started making a big breakthrough, shuttle looms slowly started disappear- ing.
At ITMA 1987 and 1991, there was no exhibitor of shuttle looms, indicating that the shuttle loom had reached its maximum saturation performance. The weft insertion rate during the above transition phase has increased from 380 m/min to a maximum of 650 m/min. The increase in weft insertion rate wa" achieved due to the following:
