Virtual Web Handling Fundamentals Workshop

Workshop Description

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 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 three-day workshop will combine classroom seminars and lab demonstrations to 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; and lab demonstrations to see web handling principles in action.

Unlike any other option in web handling education, the Optimation MCF series of web handling ‘workshops’ are one-of-a-kind training that combines classroom seminars with on-machine demonstrations.

This class will be presented virtually via Zoom video conferencing. The classroom seminars will be conducted live and the on-machine demonstrations will be pre-recorded. PDF copies of training slides will be provided to attendees prior to the class. After completion of the class, a spreadsheet summarizing data collected during on-machine demonstrations will also be provided to attendees.

Who Will Benefit from this Workshop?

This workshop is directed towards the technical employees of any level with a need to understand the fundamentals of web handling. The only prerequisite is an aptitude for technology with an interest in the connection between theory and practice.

Web Handling Workshop Outline

The three-day workshop will aim for a 50-50 split between seminar and lab demonstration time.

Seminar presentations will include:

Web Mechanics and Tensioning

  • Why tension and how much
  • Web physical properties
  • Definition of a tension zone
  • Torque generation

Rollers and Traction

  • Roller basics
  • Roller alignment
  • Roller slip

Nipping Processes

  • Pressure within a nip
  • Nipped system design factors
  • Lamination best practices
Tracking, Wrinkling and Spreading

  • Perpendicular Entry Rule
  • Causes of web wrinkling
  • Web spreaders
  • Web guides

Winding

  • Winding key process variables
  • Roll pressures and stresses
  • Factors that facilitate roll winding

 

Lab demonstrations will include:

Lab #1 – Web Mechanics and Tensioning

– Review of the tension control strategy on the Thin Web Rewinder (TWR)

– Measurement of web tensile properties

– Pi tape for total alignment and roll diameter measurement

– Micrometer for roller diameter measurement

– Dial indicator for roller run out

– Traction measurement using a hand-held Prony Brake on the TWR

– Traction measurement using the automated Prony Brake on the TWR

– Roller inertia and bearing drag

Lab #3 – Nipped Systems, Laminating

– Nip footprint and pressure measurement

– Strain matching and curl

Lab #4 – Wrinkling, Spreading, Guiding

Workshop Instructor

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 Oklahoma State University 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 Optimation Media Conveyance Facility (MCF) is a 5000-sq. ft. space featuring experimental, analytical, and limited production web handling capabilities for narrow and wide applications. The MCF, acquired in 2008 by OTI, has a 35-year history serving as an internal resource for Eastman Kodak Company, but is now available for commercial use, including serving as host for this workshop.
