CHAPTER 10BEAD AND STRIATION ROLLER ASSEMBLY34BEAD AND STRIATION ROLLER ASSEMBLY1. The Bead / Striation Roller assembly (Figure 21) is located behind the shear andis accessed by removing top cover #3. These rollers can be engaged ordisengaged as needed and can also be moved left or right to accommodatedifferent panel widths.2. The bottom bead or striation forming roller should be set 1 /32” above the driveroller to ensure proper entry into the shear. If adjustment is necessary, loosenthe four frame mount bolts “B”, and lock nuts on the two vertical adjustmentbolts “A”. Raise or lower the roller assembly by using the vertical adjustmentbolts “A” to obtain the proper height. Then re-tighten the mount bolts and locknuts on the two adjustment screws “A”.3. Next loosen the eccentric shaft lock down screw “C”. Place a 5/32” AllenWrench in the small hole at the end of the eccentric shaft, and rotate the toproller up until it clears the bottom roller. Loosen the two top and two bottomslide lock down screws “D”. Bring the panel material up to the rollers but notpast them. SHUT OFF THE MACHINE AND DISCONNECT THEPOWER BEFORE CONTINUING. Locate the bottom rollers to the desiredposition by sliding the assembly on the bottom slide bars. Tighten the bottomslide lock-down screws ”D”. Restart the machine and back up the panel untilyou gain access to the top slide lock-down screws, AGAIN SHUT OFF THEMACHINE AND DISCONNECT THE POWER. Loosen the top slide lock-down screws, and slide them into position so the top roller is directly over thebottom roller. Tighten the top slide lock-down screws “D”. Next rotate theeccentric shaft down to the desired bead depth. DO NOT go below .045”minimum clearance; excessive bead depth will distort your panel. Re-tightenscrews “C”.4. Keep slide bars lightly greased to allow bead or striation assemblies to slidesmoothly.
