HISTORY OF MARCO COMPANY INC, USA

Marco was a pump company that was purchased by Baker Perkins, sometime in the late 1960's or early 1970's. Not many pumps were made from their designs, but the one product that came with the company of which many were manufactured were the Rotofeeds. Lee Plastridge was the president of the company, and he joined Baker Perkins and became a process engineer in the lab. The Rotofeed is a machine that has a conical screw and is used to deairate materials. It also has the capability to do some mixing. Most Rotofeeds, however were used to deaerate or devolatilize materials. Many were fitted with an extrusion section for discharging the final product under pressure for making geometric shapes.
