Promécam Sisson Lehmann was a French manufacturer of sheet metal working machinery, including press brakes, shears, and shot blasting equipment. The company is best known for its technical partnership with Japanese manufacturer AMADA, which began in 1965 and led to AMADA’s full acquisition of the firm in 1986.
Design and History
Promécam Sisson Lehmann’s origins trace to the Ateliers et fonderies Sisson-Lehmann, founded in 1911 by André Sisson in Charleville (Ardennes). His daughter, Edith Cros, née Sisson (1912-2008), founded the Promécam company and became CEO of Promécam Sisson-Lehmann after her husband’s death in 1962. The company built shot blasting machines, molding machines, sharpening machines, and metal machine tools, with sites in Saint-Denis, Château-du-Loir, and Charleville.[1]
In 1965, AMADA concluded a Technical Assistance Agreement with PROMECAM SISSON-LEHMANN S.A. in France, which led AMADA to begin production and sales of press brakes.[2] Promecam had started manufacturing and selling press brakes in France in 1955, and by 1965 AMADA took over the distribution of Promecam press brakes in Asia.[3]
After the company filed for bankruptcy on March 27, 1986, AMADA acquired and reconstructed the financially struggling Promecam Sisson Lehman S.A. and established its French subsidiary.[4][5] Following the acquisition, the Promecam brand was strengthened using AMADA’s knowledge and experience.[6]
Meaning and Symbolism
Documented visual descriptions of the Promécam Sisson Lehmann logo are scarce in available sources. The company’s name combined the Promécam brand, founded by Edith Cros, with the Sisson-Lehmann establishment name from Charleville.[1] The wordmark “PROMECAM” was registered as a trademark in the United Kingdom in 1963, indicating the brand was in active commercial use during that period.[7]
No reliable source confirms the specific designer, typography, or symbolic elements of the Promécam Sisson Lehmann logo. Claims attributing the logo to a “Design Groupe Viaud” or describing its visual characteristics in 1965 cannot be verified through available documentation.
