From holjeron.com
The use of 24V Brushless DC Motor-Driven Rollers (MDR) (also known as motorized roller or powered roller) in material handling systems continues to grow as users seek the benefits provided by a powered roller system: Taking full advantage of the benefits provided by MDR requires controls to evolve. Holjeron's ZoneLink™ system provides users with three different levels of control: A ZoneLink®.S-compatible module that has higher level logic to control merges, diverts or right angle transfers without the need for a distributed control network. Products & Services
Rolls and rollers are cylindrical components used to drive, form, press together or handle webs of sheet metal, cloth, plastic, paper or other materials.
Web tension sensors are used to measure static or running tension in webs or sheets during the manufacture of textiles, paper, and other sheet materials.
Palletized conveyors are modular systems that use pallets, or trays, to carry parts from one station to the next for machining or assembly applications.
Calenders and calendering equipment apply continuous heat and pressure to densify, smooth, or otherwise modify the properties of roll goods.
Tension meters are instruments that measure tension in cable, fiber, belts and webs, or sheets.
