COLLEGE OF WINDING

The College of Winding is committed to providing quality educational materials on the fundamental principles of winding quality rolls and the tools available to support that end. This unique program combines dynamic classroom instruction, real world case studies, hands-on modeling of principles and peer-to-peer interaction on techniques and methods that are successful in today’s converting applications.

The mechanics of a profitable roll
It starts and ends with a good roll. This unit overviews the mechanics of winding and focuses on successful principles and practices applied by converters to build quality rolls. The T-N-T and Jack Daniel’s principles of winding will be emphasized.

Stress, speed and torque: How to calculate for success and know the effects when you’re wrong
Your roll needs to be properly supported and you need to know when there is a problem. This unit will overview fundamental engineering principles related to stress, speed, roll/shaft deflection and torque in the winding process. The factors effecting load capacity, critical speed and optimal torque output from shafts and chucks will be addressed.

Unwind Process: The art of making the most out of bad rolls
Sometimes you have to make the most out of what you get. This unit will review principles to help you do just that. We will review different styles of shaftless and shafted unwind machine technology and the related component technology used to support a roll. How to handle unwind roll defects such as distorted cores and out of round rolls will be addressed and the related technology that is available to help with this. Pneumatic brake technology will also be addressed.

Rewind Process: The art of making more money
A quality roll is a profitable roll.  This unit will provide you with the principles and tools to ensure every roll is profitable from start to finish. We will cover different types of winder technology and their related benefits. We will also address roll concentricity, vibration and coreless winding as well as digging into the principles of high speed winding.

Differential Winding: How slip leads to a rise in profits
Gauge bands are costing you profits in poorly wound rolls. This unit presents the causes of gauge or caliper variation and how differential winding overcomes this effect to insure you still build quality rolls. The different technology available will be reviewed and best practices used by converters will be presented.

Ergonomics in winding applications protecting your number one investment – The machine operator
Workers’ compensation claims hurt both your people and your bottom line.  This unit teaches the underlying principles of ergonomics and provides practical tools to help you assess the potential hazards in your facility.  We will overview typical hazards at converters and discuss tools and technology available to eliminate those hazards. This unit will also include case studies of ergonomic programs that have been implemented.

Applied Winding and General Considerations: How other industries handle the beginning and end of their web processes
You’re not alone in the converting world.  This unit shows how each industry – corrugating, tag and label, paper and tissue, non-wovens, laminating, packaging, film, foil and others – start and end their processes and what principles of unwinding and winding they apply.  We will also facilitate cross-sharing of ideas and provide you with the opportunity to learn from your peers in different applications.  Unique applications and the solutions applied will also be discussed. This unit will conclude with an overview of roll handling technology and some practical tools for further improving the efficiency of your winding application.

Operation and Maintenance: How to make your tools work and fix them when they don’t
Efficient operation and maintenance of your tools is as much a factor to profitability as the right tools. This unit reviews fundamental operating principles for a variety of winding component technology and the maintenance techniques applied in the field. The specific focus for this unit is on shaft, chuck and pneumatic brake operation and maintenance.
