1932–1963 : Iron Age Sumner Iron Works

• Developed the 1st helicoid-faced chipper in 1932

• Developed 1st vertical disc, horizontal feed, veneer chipper with powered feedworks

• still the basis of modern designs for chipping waste veneer.

• Weathered the Great Depression

 

1963–1984 : Silver Age Black Clawson Subsidiary

• In 1963, 71 years after the company was founded, it was acquired by Black Clawson, a world leader in pulp and paper machinery

• As a new subsidiary, it became the focus for its forest products initiative thereby broadening its line of products.

• The Everett subsidiary made the world’s largest whole log chipper (175” diameter disk)

• The Everett subsidiary invented and built the “Bellingham Barker”, the 1st of it’s kind.

 

1984 – now : Gold Age Acrowood Corporation
