Converting Projects
Project Objective: Plant Wide Process Assessment & Automation Plan
Customer: Specialty Converter, Eastern U.S.
PCT provided:
• On site evaluation of all major process
equipment and material handling systems
• Interviews with production, maintenance,
engineering, and management staff
• Development of a plant wide automation
plan
• Recommendations for equipment and
process modifications
• Estimated costs and schedules to
complete modifications
Project Objective: Improve the Performance on Several Slitters
Customer: Midwest Location of Major Blown Film Producer
PCT provided:
• On site evaluation of the slitters in order to
take measurements, observe machine
operation, and gather drawings and
program files
• This evaluation considered input from
engineering, maintenance and operations
• Modifications to the slitter speed and
tension control logic as required
• Added taper tension control to improve
finished roll quality
• Minimized lay on bounce
• Optimized slitter for lock core winding
• Retrofit existing controls and drive to
modern equipment
• On site commissioning support for starting up and tuning the new control program
• On site support for initial production at which time PCT continued to refine the system tuning

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 Swrap rolls
