About Us

Strong-Robinette Machine Corporation was incorporated in Bristol, Tennessee, on May 28, 1985. Three brothers began the business with J. Alan Robinette as President, Nolan R Robinette as Vice President, and John M. Robinette as Secretary-Treasurer.

Strong-Robinette Machine Corporation began as the Machinery Division of Strong-Robinette Bag Co., Inc. in the mid-1970’s, making the sewing equipment for its own plant as well as selling to other multiwall bag manufacturers. Alan Robinette was responsible for the development of sewing tables, automatic feeders, and counter-stackers for sewing lines. In 1979 Nolan Robinette joined the firm bringing an expertise in electrical knowledge, thus enabling this new equipment to be built 100% in-house.

The multiwall bag business in the 1980’s brought a need for high speed feeders for pinch bottom lines and accumulators for tubers. This demand brought the sale of many Model 2000 Feeders and Tube Stacking Conveyors across the United States and also in other parts of the world. In 1985 John Robinette joined Alan and Nolan to form Strong-Robinette Machine Corporation before Strong-Robinette Bag Co., Inc. was purchased by Stone Container Corporation. Increasing speeds in pinch bottom production created the need for the Model 3000 Feeder and Model 3100 Registration Unit in the late 1980’s. In the 1990’s, Strong-Robinette Machine Corporation moved into the development of heavier machines such as tubers and pinch bottomers. This movement began in 1991 with the introduction of Model 4300 Flush Cut Tuber and continued with the Model 3200 Pinch Bottomer in 1994 and the model 5300-SU Universal Tuber in 1995.

Now Strong-Robinette Machine Corporation is continuing to offer customers the highest quality in multiwall bag-making equipment ranging from small single deck feeders to 5 and 6 ply universal tubers.
