AROL, part of Pneumatic Scale/Angelus, brought its Equatorque self-calibrating servo capper to interpack. The demonstration of a press-on cap application used a mechanical system to sense bottle orientation, while the servo capping heads turn the caps to match.

Using ELAU's exclusive solution for installing servo modules on rotary capping and labeling carousels, the Equatorque replaces clutches with a servo powering each capping head. This maximizes flexibility and assures consistently accurate closing torque.

Each capping head performs a torque self-calibration with every cycle. A sophisticated monitoring system detects closing faults automatically, including no cap, cap at incorrect angle, no container and rotation of container. A simple operation sets optimum cap/container/closing torque configurations. Adjustments can be made remotely while the machine is in operation.
