Center – Folder if Available: Check roller condition and clean any excessive buildup. Inspect bushings for excessive play or wear. Clean any buildup on the folding plate. Verify brake functionality, including mechanical, electrical, and pneumatic components.
Film Unwind: Clean any excessive buildup on the drive and free-spinning rollers, and verify the drive roller is functioning properly. Ensure the dancer bar moves freely and operates as intended. Inspect the pin-perf wheels to confirm they are functioning correctly, producing good perforation without slitting the film, and check for excessive wear on both the rollers and perf wheels.
Infeed Conveyor: Inspect chains, sprockets, and gearbox for proper lubrication and signs of wear. Ensure guide rails operate correctly and all mounting hardware is secure. Check the infeed clutch for proper action and safety, test the variator while the conveyor is running, and confirm the E-Stop functions as intended.
Inverting Head: Inspect condition and ensure no excessive buildup. Check vertical and horizontal movement for proper operation and locking.

Control Panel: Verify all lights and buttons work. Check temperature controls for proper readings and functionality.
Scrap Winder: Inspect all belts and speed control. Clean as needed.
Side Seal Assembly: Check overall condition and safety features, including seal wire/hot bar, springs and bushings, air cylinders, cover plates, timing belts/ pulleys, nip rollers, seal integrity, wire contacts, lubrication, and vertical movement.
Side Seal Conveyor: Inspect belts, rollers, bearings, sprockets, chain, and conveyor adjustment.
End Seal Assembly: Inspect hot knife, blade, pad, film clamps, safeties, photo eyes, snubber cylinder, brake, horizontal movement, shafts/bearings (H), vertical movement, shafts / bearings (V), end seal cylinder, and crank assembly encoder (Tooth Counter).
Discharge Belts: Inspect condition and ensure free spinning.
