Heidelberg Superspeed have uneven pressure
Hello,
my windmill start to act rly strange,I use press for die cutting and cutting labels on sticky foil.few days ago I notice I have uneven pressure (top of place is cutting while bottom dont even show any line) when I try to cut labels on sticky foil because I need to cut only top layer of the foil because of unsticking.I check safety collar(T0152) and its look ok so Im wondering is there any other safety collar or pressure adjustment.
Before this my windmill was runing excelent with even pressure on whole plate without packing or tape to increse pressure

Edit
sorry for my bad English
collar is bad. Sometimes you cannot tell by looking. Change shear collar.
ok,I will try that and post here if problem is fixed
