Dancer or Load Cells – Which Should I Use?
Montalvo Applications Specialist
I am frequently asked this question, and my standard answer is that: it depends. It depends upon the type of process (slitting, printing, coating, laminating, die cutting, etc.), the range of products being run (rigid, extensible, deformable, etc), whether flying splices and/or turrets are involved, and incoming roll condition.
Dancers are very effective at minimizing web tension upsets due to out-of-round master rolls, rapid speed changes, indexing operations or any other process that introduces tension instability. The ability of a dancer system to absorb these upsets with the storage inherent in the system clearly offers some advantages for good closed-loop tension control. There are a few things to keep in mind when comparing or considering a dancer system for control.
