Sankyo developed the NC loop controller in order to create the ideal loop shapes required by the feeding device, using servo technology. This VLC sets up optimum feeding by forming ideal loops in the space allowed, taking advantage of the spring characteristics of materials and stabilizing the loop using a sensor and servo control. The VLC has excellent handling characteristics in that it does not scratch, kink or dent material and can improve both quality and productivity.
The VZA and VZC series are motor cores for EV, and are models compatible with thin and long sheet feeding with a thickness of 0.3 mm or less. The loop shape of the material is less likely to collapse due to the effects of gravity, allowing for stable high-speed feeding.
