4.3.2 Thread course (Fig. 11 and Fig. 12)
Because of the pneumatically controlled gathering device two successive
Asked thread tensions are grown. The front tension (4) operating normally, the
rear thread tension (5) activity occurs when the partition plate of Gathering
device swung and fullness, as is gathered at the toe. For this shirring a firmer
tension is needed to better fix the resulting material folds on the shoe sole, and
can get a good gathering. After swinging the partition plate, the front is now
more normal tension back into activity and that the rear thread tension is
released.
