Doubling Control with Chase-and-Follow Function

Doubling systems permit different strips to be placed on top of each other with precise edge alignment. The doubling control places a slave strip symmetrically or asymmetrically on top of a master material. The application position is specified via defined recipe data.

CCD cameras detect the position of the master material and guide the strip to be applied to the master material. The movement of the strips is carried out in two phases. The first phase is pre-positioning. The fine positioning of the strips is carried out in a second phase via a machine speed-dependent controller with higher-ranking disturbance eliminati

Special Features

The special guiding principle of BST eltromat avoids the tilting of the material after the guiding roller and increases the system accuracy.
