Mechanical Master/Slave (legacy): The Master sensor is mounted on a motorized slide that physically chases the web position. The Slave sensor is mechanically linked to move the same distance. This creates wear parts, lag, and "loop within a loop" tuning …
Yes. This is a unique capability of [rr] Master/Slave guiding that legacy systems cannot match. By using wide field-of-view sensors ([odc 480], [odc 768], or [odc 960]) that see both edges of each web simultaneously, the controller can calculate the …
Both [scu5] and [scu6x] controllers support two independent sensor channels , enabling single-controller Master/Slave configurations: Channel 1: Master sensor (monitors reference web position) Channel 2: Slave sensor (provides feedback for the guided web) …
In Master/Slave guiding, timing is critical. The Slave guide must correct for a Master web movement at the exact moment that movement reaches the lamination nip. The rule: Web path distance from Master Sensor → Lamination Nip should equal the distance …
Yes. [rr] systems support multi-lane cascading alignment where each lane's edge position automatically sets the guide point for the next lane. Example configuration (14 lanes): Each lane has two sensors: one monitors the "master" edge, one guides the web …
[rr] electronic Master/Slave guiding eliminates the mechanical components that require constant maintenance in legacy systems: Eliminated maintenance items: Motorized sensor positioner motors and drives Lead screws and anti-backlash nuts Sliding brackets …
Standard web guiding steers the web to a fixed position, but in tool tracking applications like slitting to a printed line, the sensor must see the relative position between the tool and the web. Here's why fixed sensors fail: Fixed sensor upstream: The …
In slit-to-feature applications, the cut must align with artwork or a printed line on the web—not the web edge. [rr sensors] enable this through dynamic tool tracking: Sensor mounting: The [odc 96] or [odc 192] sensor attaches directly to the knife holder …
In Li-Ion battery electrode coating, the coating must align precisely with the current collector foil. Steering the foil creates stress and wrinkles that cause defects. Instead, [rr sensors] enable coating head chasing: Sensor placement: [odc 96] or …
In chasing applications, process upsets can cause the web to wander significantly—due to splice passage, tension changes, or roll eccentricity. This exposes a critical weakness in narrow-range sensors: Narrow sensor problem: If the target (line, edge, or …
