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