1. Feeder Glass too cold   1. Feeder Adjust the feeder temperature   2. Machine Setup and Operation Neck ring closing too soon when reverting pinching the finish Insufficient or unequal neck ring opening Incorrect cushioning of invert mechanism on the blow mold side Neck ring opening too hard Incorrect setting of blowhead (out of center) End of outstroke cushioning on take-out incorrect Take-out tongs are out of line or closing too hard Incorrect setting of neck ring over the mold Bottom plate too high   2. Machine Setup and Operation Retard neck ring closing Increase neck ring opening Adjust cushioning of invert mechanism Adjust neck ring opening for smoother action Adjust blow head over blow mold Adjust outstroke cushioning of invert mechanism Adjust take-out tongs, allowing them to close slower Set neck ring over blow mold to neck ring setting gauge Correct the bottom plate mechanism setting   3. Mold Equipment Bottom plate too tight in mold recess (resulting in mold opening too hard) Shoulder radius too sharp (for odd shape bottles) causing bottles to rock on bottom pate resulting in damage form take-out fingers   3. Mold Equipment Check equipment against mold gauges Ensure shoulder radius has some relief   4. Stacking Equipment Incorrect setting of stacker bar (pushbar stacker) Incorrect timing or setting of tong stacker head Incorrect positioning of ware on cross conveyor (gang stakcer of push bar stacker)   4. Stacking Equipment Correct setting of stacker bar Correct setting and/or timing of stacker tong head Correct positioning of ware on cross conveyor   5.
