A crank tool for a locking shaft is manufactured to increase an injection rate of an ultra high-pressure water by increasing a delayed phase angle by increasing an eccentricity amount of a crank pin for the locking shaft drive of a conventional water jet tool, to maintain an interlace, and to lengthen an injection period of the ultra high-pressure water. A crank tool for a locking shaft installs minor axises(15a,15b) set up in both sides of a main gear(14) installed at a principal axis(11) on a side frame(10) of a water jet loom and crank gears(12a,12b) in each minor axises. The crank pin(16) is installed at one point of the most distant place in a rotation radius of the crank gears. A wide width geotextile having of a maximal width of 4.8m is manufactured by increasing an eccentricity amount of a crank pin and a delayed phase angle. |
