Project Objective: Modify Slitter Mechanics to Improve Reliability

Customer: Midwest Location of Major Blown Film Producer

PCT provided:
• Engineering study to recommend mechanical

changes

• Created a pass line drawing from customer

drawings

• Simplified the pass line by removing several rolls

and developed alternate thread paths for the
system

• Replaced 4 rolls in the unwind section based on

engineering discoveries

• Replaced 3, high inertia, “billy rolls” with a single,

low inertia roll

• Modified upper fold board roll for load cell mounts

to provide appropriate tension feedback

• Replaced the nip roll mechanisms with driven S-

wrap rolls
