Web Lines: Thinking About New Equipment?

A new year often brings new budgets and thoughts about new equipment. If you are lucky enough to be handed a project to buy new converting equipment,

Roll Winding Dynamics

Materials today often are more than they may seem at first glance; many are manufactured with non-conventional properties. Label and semi-glossed enamel stocks are engineered

Get a Grip: Driving Your Web

In my October 2007 column, In Search of Tension Isolation, I myth-busted the belief that a high traction driven roller can completely isolate one tension

Picking Up the Pace

As press manufacturers continue to introduce presses that can run faster in theory but not necessarily in practice it falls to the manufacturers of register

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.

In Search of Tension Isolation

In web handling, one of the myths told most frequently is that of the independent tension zone, protected from other tension zones by the protective powers of the tension isolation. Like most myths, we want to believe, but alas, scientific reason is the myth buster.

Ready for Change

Expensive materials change attitudes at Gintzler Graphics, where automatic splicing capabilities from Martin Automatic reduce waste.

Support Your Rollers

How should a roller be supported or attached to your equipment? To answer this question, let’s review your roller support needs and your options to meet these needs.

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

This year, Montalvo Corp. celebrates 60 years of providing brakes, clutches, and electronic web control equipment to the converting industry worldwide.
