10/47 ekr CON 600, ekr CON 600 net – Master-Slave Guiding with Sensor Positioner
The number of required edge sensors depends on the desired
guiding modes.
Master-Slave Guiding Possible Guiding Modes Reference Point for Guiding
with two edge sensors Web edge guiding left or right web edge
with four edge sensors
Web edge guiding left and right web edge
Web center-line guiding web center-line
With the displayed version of the master-slave guiding with four
edge sensors, sensors 3 and 4 detect the position of the unguided
MASTER web and sensors 1 and 2 the position of the guided SLAVE
web (following web). If the MASTER web moves laterally to the
web running direction during the laminating process, the control
automatically guides the SLAVE web by the respective adjusting
movement of the guiding device (e. g. rotating frame guide).
In this way, during web edge guiding the master-slave guiding
keeps the preset distance (offset) of both web edges constant
(offset ≠ 0) or ensures that both web edges are positioned pre-
cisely over one another (offset = 0).
During web center-line guiding the master-slave guiding ensures
that the SLAVE web is guided exactly to the middle of the MASTER
web (offset = 0) or that the lateral displacement between the cen-
ter-lines of the SLAVE and the MASTER web remains constant (off-
set ≠ 0).
3.2 Guiding Modes
For the laminating process the Master-Save Guiding with Sensor
Positioner permits the following guiding modes.
Guiding to the left web edge Guiding to the right web edge Web center-line guiding
