How to Install and Adjust a Striation Assembly on an NTM Rollformer

This practical guide is designed for metal rollformer operators, particularly those working with SSQ II, SSH, and SSR MultiPro panel machines. If you’ve recently received a new striation assembly, follow these steps to ensure a correct setup. Check your machine manual (Chapter 10) for bead roller assembly diagrams and additional information.

Step 1: Safety First

Before starting any setup, ensure the roll form machine is locked out and tagged out, disabling any possibility of accidental power engagement. Always work around the shear in front of or behind it, but not through it, to maintain safety.

Step 2: Tools Required

Prepare the following tools necessary for the setup:

– 7/16″ wrench (for height adjustment)

– 1/2″ wrench (for side-to-side adjustment)

– 5/32″ Allen wrench (for adjusting pressure)

Step 3: Installing the Striation

1. With assistance, carefully place the striation assembly in the rollforming machine. Secure the top bolt while your helper starts on the other side.

2. Continue to install and tighten the bottom bolts.

Step 4: Height Adjustment

1. Set the height of the striation roller to align with both the drive roller and the top of the shear.

2. Once aligned, tighten the bolt to secure the adjustment.

Step 5: Striation Placement

1. Based on your profile, determine the number of striations needed. For instance, if four fit on top and three on the bottom, adjust accordingly.

2. Reposition unnecessary striations by removing the stiffener bar and moving the striations and spacers to the side, then snug the bolts to prevent the striations from drifting.

3. Replace the stiffener bar, ensuring it’s aligned with the last station, then tighten.

Step 6: Reinstall and Align the Stiffener Bar

Once adjustments are made, replace the stiffener bar, ensuring it aligns with the last station to avoid any interference with the material flow.

Step 7: Centering the Striations

1.  By eyeballing it, position the top striations as centrally as possible within the pan and then tighten them securely.

2. Utilize spacers to maintain even spacing between the striations, adjusting the bottom striations to align with the top ones.

Step 8: Final Adjustments and Tightening

1. Tighten all bolts to ensure all striations are secured and well-aligned within the machine, using the spacers for guidance to achieve even spacing.

2. Check the alignment by comparing the distances on the other side of the pan and making adjustments to center the striations.

3. Once complete, run a piece of material through the machine with the secured striation assembly.

Step 9: Setting Pressure and Running Material

1. Using the 5/32″ Allen wrench, tighten the striation rollers by inserting the wrench through the hole in the center of each eccentric shaft. Adjust the pressure by rotating towards the shear until the desired tightness is achieved. Tighten the bolts for each striation roller.

2. Feed the material through to check the imprint quality, adjusting pressure as necessary to achieve an even print.

On the panel, you should be able to tell where the last striation roller ends and the clip relief begins. Measure each side to determine the distance between the two.

Measure and mark the bar.

Step 10: Center Striations for Even Prints

1. Calculate the difference of the two measurements (one on each side) and divide by 2 to determine the centering adjustment.

For example, say the measurements are 23/8” and 1 ½”:

2 3/8 – 1 ½ = 7/8”

7/8”/ 2= 7/16

2. Mark the adjustment distance on the machine bar by measuring from the first striation in the direction you want to make the adjustment. Repeat on the bottom striation.

3. Loosen each roller and slide the striations over to the calculated measurement (for example, 7/16”).

4. After repositioning both top and bottom striations to the marked position, use spacers for accurate placement. Tighten to secure the new positioning.

Step 11: Final Check and Start-Up

1. After all adjustments, restart the machine and push the material forward past the initial print marks to see the new, even print.

2. Make any final tweaks to ensure the striations are perfectly centered and producing the desired print depth by loosening the bolts and eccentric shaft to adjust. Check for centering and adjust as necessary.

By following these detailed steps, you can ensure your new striation assembly is properly set up for optimal performance on your roll form machine. For further learning and troubleshooting, refer to your machine’s manual or New Tech Machinery’s additional resources.
