How to Set First Operation by Alex Ganni

In this video, we are going to show you how to set up a first operation roll. Whether you are installing new tooling or whether or not you’re doing an adjustment for a production run, the principles will all be the same.

The two adjustment points to make today are in and out, using the adjustment screw (see video for visual), and are up and down with our adjustment screw (see video for visual).

In this case, I’m going to be looking at the first operation of station one. Assume that one of the technicians just replaced the tooling.

Put a stripe down from the shield. This goes all the way down the coating of the roll all the way down to the base. The reason for doing this is because as you rotate the machine, you want to confirm that the roll is not spinning. If it is, that means we have a problem.

Begin to spin the machine to check first operation and confirm the stripe did not move at all. If nothing moved, you have the clearances to make the initial adjustments.

The first item to use is the RSS MACLIN pin gauge height kit. It is important when setting the vertical height.
Once it’s placed, these are the other pieces that you will need:
– 13/16” Box End Wrench
– 5/16” Box End Wrench
– ¼” Allen Key
– 1/8” Allen Key
– Taper Feeler Gauges
– RSS MACLIN Pin Gauge Height

Start by loosening the set screw. If you look above the adjustment bolt on the lefthand side and right below the height adjustment screw. Now you will need to break the castle nut free. This reduces the tension off the block.

Now that the RSS MACLIN pin gauge height kit is in place, rotate the roll to identify the contact point. Rotate the roll downward. As you do that, spin the roll to identify when the roll has made contact with the chuck. After your adjustments, set the dial to zero. Raise the roll to .003.

At this point, you will be using your feeler gauges. What’s important is to identify the can manufacturer’s material guide sheet and that’s what you will use to determine the proper thickness.

In this case, we are using a Ball 202. Then pull up your material sheet. For this, the first operation should be .074 +/- 2.
Pull down the pin gauge, you will notice a lip where the profile is. Press it flush and try to keep it as plum as possible.

Then, look for drag with a feeler gauge or use an angular gauge. Whichever is easier for you.

Pro tip: Back the seam out of a full revolution and adjust going inward, removing backlash.

Now that the initial drag is set up, put the box wrench up to the bolt and lock the castle nut and set screw. Double check your work by using a torque wrench to make sure it is locked up properly.
