with the central movable plate of cam liver receiver plate. Figure 12 (Kaizen 5) shows the design change of side support mounting mechanism. Earlier, the door plate had a continuous slot to fit the side stopper according to the width of the coil. The operation was taking more time as trial and error was involved in the process. In the proposed Kaizen 5, the continuous slot was replaced with numbered round slots, with center pitch distance of 2.54 cm. The side stopper can be directly fitted to the slot according to the width of the coil; consequently, no adjustment is needed. All these design Kaizens are expected to reduce the element setup time considerably (by 75 %).
The improvements in other Kaizen targeting changes in work method are as follows:
& Provide scale at both side of the expander to avoid visual adjustment error.
& Keep the expander accessories on a movable trolley, which can be easily brought near when the setup is going on to save travelling time.
