An apparatus for controlling an air jet loom and, in particular, for controlling a loom used for weaving cloth having move than one pick range. One use of such cloth is for tire-cord fabric having a body portion having between 1 and 3.5 ppi and at least one tab portion having between 3.5 and 50 ppi. The system includes an automatic temple insertion device. The system further includes dual nozzles to automatically switches from tab to body; automatic pick spacing change from tab to body; and an automatic tension level control. The system permits multiple tabs on a roll for separating multiple body portions of the roll, providing an inspection segment per roll, and providing a cut line either by 'no picks' or by changing the filling within the tab.

Loom temple control system to vary pick density

The cam shaft of a fluid jet loom, which cam shaft normally operates the warp yarn harness frames, is disengaged from the machine drive mechanism by a clutch mechanism. The cam shaft is then rotated manually by the operator, as the machine drive is by-passed, to reposition the harness frames at a proper position such that faulty picks can be easily removed.
