Sixty Years of Machines, Part V

Joe Kannapell

Part V: The Gantry Gains Ground The roller gantry had two major obstacles to clear in the 1970s, both erected by its inventor, Carroll Sanford. Both were delineated in hard-to-evade U.S. Patents. The first was on the machine itself and the second was on the connector plate that it required....

How Do Your Manufacturing Errors Rank on the List?

Glenn Traylor

Eleanor Roosevelt once said, “Learn from the mistakes of others. You can’t live long enough to make them all yourself.” Apparently, she never worked in a truss plant, where I think everyone will make them all at least once. But humor aside, let’s take a look at the...

Sixty Years of Machines, Part IV

Joe Kannapell

Part IV: Early Roller Gantries The roller gantry dominates today’s truss production, but it hasn’t always done so, despite the fact that it hasn’t changed much over sixty years. The reason for its relatively slow ascendency is found in its origins and in its adaptations over...

How Important are Construction Tolerances?

Glenn Traylor

Back in the days before Autoset C®, Matchpoint®, and Wizard®, truss set-ups and the truss profile were dependent on the truss builder’s ability to accurately jig the truss being built using cross reference information and data. For example, a heel to peak measurement was taken...

Part III: Table Presses More CMs are “doing it right the first time” via vertical presses, taking advantage of their flexibility and the quality of their production. But few realize that some of the most successful plants in our industry started with table presses. These presses...

Are You Creating a Culture of Quality?

Glenn Traylor

On a recent trip to Japan to observe construction manufacturing methods, I was struck by the amount of time a plant manager spends on the production floor. Comparing this Japanese methodology to our truss industry, our plant managers and upper management spend relatively little time engaged in...

The Last Word: Vertical Presses — The World Record

Joe Kannapell

Forty years ago, a frenetic fray raged over the World Record for truss production. While CMs across the country competed, the two main players, Littfin in Minnesota and Dickie Vail in Louisiana, produced numbers that may never be equaled. The massive trophy, displayed today in the lobby of...

Sixty Years of Machines, Part II

Joe Kannapell

Part II: A Pressing Issue Why reflect on the oft-derided C-Clamp as it fades into truss industry oblivion? Because it holds the world record for truss production, unmatched yet, even by robots. And although it debuted half a century ago, its design has never been equaled. And remarkably, this...

How Do Your Trusses Stack Up?

Glenn Traylor

Do you vertically stack your trusses or horizontally stack them? How does the method impact quality? How does it impact safety? Do you know the arguments for either preference?
