Dead Head Skidder
Cans that qualify as a “Dead Head Skidder” don’t just listen to Phish in a van, they didn’t properly seam! The main causes of of this damage are pin height being too high, Op rollers too close, and spring pressure being too low. This is the effect of the can being lifted into the seamer chuck without proper engagement, or, at times, the Op rollers themselves not allowing the can to rotate.
Order of Operations:
Measure pin height and compare to your spec sheet, confirming it is correct for the specific can size.
Check Op distance as well as Op roller free spin. See "Adjusting Op Roller Distance" walkthrough for more information.
Ensure the knockout rod in the center of the chuck is moving freely up and down.
Check that spring pressure is within range (110-120 ft lbs).
Check that the height of the physical cans is within tolerance reflected on the spec sheet provided from your can supplier.
***If your pin height is unknown, the equation for setting pin height is:
Can Height - Lid Countersink - .042 = Pin Height.***
