The three Roll Pyramidal DAVI MCO is the most common design in the industry, with the top roll fixed, and the two side rolls that move up and down to pre-bend the edges, and to roll the plates.
The most economical roll for plates from 15-20 mm thickness up to 80-100 mm, and it is recommended for limited production volumes where the operators’ skills are a must.
The MCO is called “double pinch” because it performs the pre-bending of both ends of the plate without removing the material from the machine (impossible on any single initial pinch, asymmetric design).
As the side rolls raise widely and drop to pre-bend the two edges, the large free access allows you to form a high stock bar through the rolls, compared to other roll designs.
The three rolls are powered with three independent hydraulic motors, splined on the roll shafts, providing the most powerful torque transmission, and ensuring excellent plate feeding without the risk of plate slipping.
Other plate roll manufacturers have only the top roll OR only the two side rolls powered, making it difficult to feed properly with thin, narrow, or large diameter cylinders. The idle rolls can be powered but only on request, and with small and low powered auxiliary motors.
All three rolls are efficiently safety braked, automatically, and hydraulically instead of using low efficiency, consumable brake linings common to other brands
