EMG strip guiding systems: Know-how for users - 05

Steering unit with proportional guide

In this and the following articles in this series we summarize know-how on the use of EMG strip guiding systems and try to provide you with the necessary basis for the planning of the applicable components and for the design of the systems.

Steering unit with proportional guide 

Usage and application:
The two deflector rolls required for bridging strip pass line between accumulator and strip process section are used together with the SRD steering unit, which acts merely proportionally. This steering unit type has the advantage that it can be installed in tightly packed areas of a plant, since short free infeed and outfeed distances are sufficient due to the low edge force. 

Operating Principle: 
In the event of an incoming misalignment, the strip is not prevented from running laterally on the guiding roll itself, but the strip is transferred back to the line at the predetermined point. The strip guidance correction is proportional to the adjusting of the steering frame - the incoming and outgoing strip always forms a right angle with the swivel plane. The maximum correction capacity is determined by the swivel angle and the distance from the incoming and outgoing strip plane on the steering frame.

As an example for the detection of the strip position, the maintenance-free inductive strip centre sensing  system type SMI is arranged directly behind the steering unit.

In summary - Which EMG components do I need?
