Company History

How it All Started
Over seventy-five years ago, when founder Gerald “Doc” O’Rourke saw that neighborhood kids needed footballs and basketballs, he started a basement operation to provide them. After introducing a line of sewn leather industrial bellows, Dynatect (formerly A&A) began designing and manufacturing components used in virtually all types of equipment and machinery, becoming a single-source provider for machine protection, cable/hose management, and compartment roll-up doors. (Slip clutches, ball screws, and molded products were added in the last decade).

Today, Dynatect is a market leader in industrial equipment protection with eight production facilities and over 600 employees worldwide. Dynatect provides customer proximity all over the world thanks to its subsidiaries in Europe and Asia.

  • 1945:  Gerald O’Rourke founds A&A Manufacturing in Milwaukee, Wisconsin. Initial offerings include sewn fabric footballs and basketballs in response to a lack of youth athletic equipment by manufacturers who were previously redeployed to wartime production.  Company founder uses his initials “GOR” as prefix-branding on many products including the subsequent umbrella brands of Gortite and Gortrac. (Since 2014, the company’s contemporary name is “Dynatect”)

  • 1949:  Dynatect shifts focus to producing flexible fabric bellows providing dynamic protection for industrial applications including machine tools. Over the following 20 years, Dynatect adds fabric roll ups covers and metal roll up covers. These offerings and others evolve into today’s highly recognized line of dependable Gortite protective bellows and covers.

  • 1964:  Custom Products Corporation (CPC) is founded in Connecticut, manufacturing slip clutches under the brand Polyclutch.

  • 1967:  Dynatect adds telescopic metal cover and wiper capabilities for machine tools under the Gortite brand.  Subsequently adopted by the largest US OEMs as industry standard.
