Web Handling Fundamentals Workshop
New College Institute
191 Fayette Street
Martinsville, VA 24112
Web handling is a process engineering discipline focusing on improving productivity and reducing waste
of product made from papers, films, foils, nonwovens, textiles, or any thin, continuous material.
Many manufacturing trends create new challenges for web handling and winding, including thinner,
wider, or more delicate products, faster or more integrated processes, and ultra-clean or hazardous
environments – all increasing the potential for web handling defects. Learning to handle these materials,
processes, and environmental challenges will provide your company with a competitive advantage.
This five-day workshop will cover key concepts to optimize your equipment and process designs;
practical steps to eliminate waste from breaks, deformation, scratches, alignment errors, wrinkles, and roll
defects. This workshop will be held at the New College Institute in Martinsville, VA. The seminar will be
held in classroom 107 and will be complemented with labs in the Academic Coater Bay where web
handling principles will be demonstrated.
Unlike any other option in web handling education, this workshop provides one-of-a-kind training that
combines classroom seminars with on-machine demonstrations.
Web Handling Workshop Outline
The five day workshop will aim for a 50-50 split between seminar and lab demonstration time.
Seminar presentations will include:
Web Mechanics and Tensioning
Rollers and Traction
Tracking, Wrinkling and Spreading
Lab demonstrations will include:
Lab #1 – Web Mechanics and Tensioning
- Review of Academic Pilot Coater tension control strategy
- Review of the WCTM (web conveyance teaching module)
- Measurement of web tensile properties
- Measurement of coefficient of friction
- Measurement of web camber
Lab #2 – Rollers and Traction
- Wiki stick for roller tramming and precision level for roller leveling
- Pi tape for total alignment and roller diameter measurement
- Micrometer for roller diameter measurement
- Dial indicator for roller run out
- Traction measurement using a hand held Prony Brake on the WCTM
- Traction measurement using the automated Prony Brake on the WCTM
- Roller inertia and bearing drag on the WCTM
Lab #3 – Nipped Systems, Laminating
- Nip footprint and pressure measurement
- Strain matching and curl
Lab #4 – Wrinkling, Spreading, Guiding
- Perpendicular entry rule
- Web guiding demonstration
- Shear wrinkles due to misalignment on the WCTM
- Spreader and anti-wrinkle comparison on the WCTM
Lab #5 – Winding
- Wide web winding
- Low and high speed winding
- Various methods of characterizing roll hardness
- Winding model predictions
The workshop will be presented by Dr. Kevin A. Cole of Optimation Technology, Inc.
Dr. Cole, a Senior Web Handling Development Engineer with Optimation Technology Incorporated has a PhD in Mechanical Engineering from the University of Rochester. Kevin developed his expertise in web handling over his 20+ years working for Eastman Kodak Company and led their internal training program on winding and conveyance process fundamentals. He was also an active participant in the OSU WHRC, including chairing their Industrial Advisory Board for four years. Kevin has a rare combination of excellent problem solving and modeling skills, allowing him to comfortably move between production and developmental work.
About the Workshop Facility
The workshop will be conducted at the New College Institute in Martinsville, VA. The seminar portion of the workshop will be held in classroom 107 and the lab portion of the workshop will be held in the Academic Coater Bay where a full process coating/laminating machine has been located to serve as a teaching platform for coating formulation, web coating, web dynamics, machinery control and process measurement and control in support the Phase I, II, III and IV Curriculum in Manufacturing and Performance Films Technology at the Center for Advanced Film Manufacturing.
