What Mechanisms Cause a Web to Shift Laterally?

Web Handling expert Tim Walker identifies the five culprits that cause a web to move off centerline.

Web Lines | Curl Mechanics Pt. 2—Transverse Direction Curl

In Part 2 of this four-part series on curl, web handling expert Tim Walker tackles three common sources of TD curl.

Eliminating Boundary Layer Air During Winding

Eliminate boundary layer air  while winding rolls of film, in most cases, by using a lay-on roller. For coating and extrusion technology, vacuum boxes or electrostatic pinning can sometimes–though infrequently–be effective.

In this first part of a four part series on curl, web handling expert Tim Walker discusses curl in coated and laminated products

Web Lines | Winding Process Fundamentals, Pt. 3

In Part 3 of this four-part series, web handling expert Tim Walker answers the question: How do dimensional changes within a roll (e.g., compression) change roll strains and stresses?

Basics: What Are the Key Process Variables of Winding?

Basic definitions of tension, nip, and torque help describe what variables are important when winding a roll.

What impact can temperature change have on a roll?

The best rule of thumb is to avoid heating or cooling winding or wound rolls. Keep a roll's temperature stable.
