Web Handling


Common web handling challenges include: 

* Wrinkles, edge fold overs and how to keep the web flat through the process 

* Cross deckle basis weight variations that results in floppy edges, baggy lanes and camber

* Web weave, span interaction and how to guide the web 

* How to control tension via draw, torque or tension loop 

* Wrinkles, neckdown and web breaks during a zero-speed splice 

* How to control a process with an accumulator (festoon) 

* Loss of registration during a splice event or speed change 

* How to process lighter webs at higher speeds to reduce costs

* What is required to run more delicate laminates that are first to the marketplace 

The term "web" is used to describe thin materials which are manufactured and processed in a continuous, flexible strip form. Web materials cover a broad spectrum from films, paper, tissue, nonwovens, elastics and laminates. 

* Web handling involves the physical mechanics related to the running and control of continuous web through manufacturing processes and converting machines. A primary goal of web handling is to transport the material without incurring defects and losses. The challenge is to run processes faster with lighter materials to reduce cost or to process more delicate laminates that are desired in the marketplace. 

* Web handling is a science which involves many topics: web properties, longitudinal dynamics, wrinkles, rollers, spreading, lateral dynamics, guiding, sensors, span interactions, winding, slitting, unwinds, accumulators, laminating and converting. 

* The Web Handling Research Center (WHRC) at Oklahoma State University is the only center of its type in the world. Established in 1986 they are focused on expanding the knowledge base in web handling while transferring knowledge to their industrial sponsors. I was the leader of KC’s open innovation program with the center for 20 years. 

I was able to leverage this knowledge to eliminate persistent quality problems, improve existing process and develop new to the world processes that were first to market. 



Winding is an integral process in nearly all web materials such as paper, film, tissue, nonwovens, aluminum and steel. Wound rolls are the most convenient, economical, and most prevalent form of storage and transport for web materials. 

From a business standpoint web materials are sold based on two broad categories: 

* Geometry – Diameter, Width, Core Diameter, Roll Length, Lay flat properties, ect

* Physical Properties – Modulus, Tensile strength, Caliper, Softness, Color, ect 

There are only two types of wound roll structures. Each type has a unique combination of stored stress and strain. The wound roll structure will directly impact your physical properties and geometry. 

Common wound roll defects: 

* Loss of caliper in high loft webs 

* Telescoping, cinching, gross internal slippage, torque capacity 

* Large flat spots due to storage & handling

* Floppy edges, baggy lanes, camber, lay-flat 

* Slit width growth 

* Roll blocking

* Strain registration shift 

Converting Expert understands the science of winding and wound roll structures. 

* Expert in determining which roll structure is in place

* Demonstrated ability to document actual stored stress and strain and how they impact your delivered quality to your customer 

* In depth understanding how tension, nip and torque impacts wound roll structure  

* Demonstrated ability to solve winding issues for nonwovens, elastics, film, tissue and laminates.
