Here’s the history of the company:

Company History Timeline

Frank Edge

ESCO [Edge-Sweets Company] got its start in 1883 when Frank Edge fabricated his first jigsaw blades.

Frank Edge Company Formed

Building on this concept, Frank formed The Frank Edge Company in 1887 to produce saw blades for the booming furniture industry in Grand Rapids, Michigan.

The First 70 Years

The first 70 years of the company were spent supplying blades and equipment to the bustling furniture manufacturers.

Edge Saw Formed

In 1953, Edge Saw was formed to manufacture the first saw for cutting flexible “foam rubber.”


By 1957, the manufacture of foam cutting equipment was the main activity for Edge Saw and growth of the company kept pace with the fast growth of foam production in the U.S.

Edge Conveyor

In 1971, Edge Conveyor was formed to supply specialized conveyors essential to economical foam production. With the advent of Edge Conveyor, the company expanded its production facilities and its engineering capabilities and offered the foam industry high volume production cutting lines to supplement foam fabrication on individual units.

Purchase North American Urethanes [NAU]

In 1973, Edge purchased North American Urethanes (NAU), a company with several years experience in the engineering and manufacture of urethane metering and dispensing equipment. With the acquisition of NAU, Edge Industries became the only machinery company in the industry capable of supplying equipment for the production, processing, and cutting of soft or rigid foam. The acquisition of NAU’s Machinery Division added foam and elastomer dispensers to the product line and gave Edge the ability to provide “wet end” systems for flexible and rigid foam.

Edge-Sweets Company Formed

In 1985, Edge-Sweets Company was formed as Edge merged with Martin Sweets Company of Louisville, Kentucky, a company who similarly specialized in the manufacture of machinery and equipment for processing and cutting of polyurethane foam products and other cellular and noncellular plastics.


Edge-Sweets Company, today referred to as ESCO, resides in a 70,000+ square foot facility in Grand Rapids, Michigan and offers the combined products and knowledge of both cutting and dispensing equipment, along with a unique ability to custom engineer systems.
