Parallel Protocol

Roll alignment is a requirement for every converting process that produces some sort of web, film, or coating. When a machine is first installed, each

Differential Winding Limits: Part I

The purpose of differential winding is to apply a desired torque to two or more rolls winding on a single shaft. Differential winding allows multiple rolls to turn at differing speeds, with each roll free to slip at the speed required to compensate for roll-to-roll diameter variations and strand-to-strand length variations.

Slitting & Rewinding Fundamentals for Converters

The CEMA Slitting & Rewinding Fundamentals for Converters Seminar will be held November 13 and 14, 2007, in Minneapolis, MN, and will take you step by step through the best practices techniques in such areas as winding, slitting, cores and cutting, retrofitting, chucks, shafts, spreading, and guiding.

Baggy Webs: Part 4 Minimizing

What does minimizing a baggy web mean? Two things. First, we would like to minimize the level of bagginess in our webs. Second, we would like to minimize the waste associated with running the inevitable baggy web in our processes. To minimize the creation of baggy webs, we must take on their causes.

Automated Web Handling Reduces Costs

Germark finds automated web handling equipment from Martin Automatic boosts productivity while offering fast payback.

Baggy Webs: Part III-Causes

We know baggy webs are a problem and we know we can measure them. What do we do next? First, we need to find a way to fix it in the short term. Second, we can work on a long-term plan to prevent baggy webs from happening.

Under Pressure (A Brighter Look)

Mr. Starcevic taught my 8th grade algebra class and was one of my most memorable teachers. He quizzed us every week, and as he passed out our graded results,

Montalvo Turns 60

Back to School for Web Handling

Maxcess University’s Conference Week program has lofty objectives. The Apr. 16–20 event that PFFC attended at the Hyatt Hotel covered the fundamentals of web guiding, tension control, slitting, and winding in a university-style format that combined lecture, video, and hands-on application of web handling techniques in a lab setting.
