Couch Roll Double Doctor Blade — common questions
What is the advantage of two blades in one holder?
The second blade is already loaded and aligned. When the working edge wears, the change is a fraction of the downtime of a single-blade holder.
Which blade material suits a couch roll?
Usually a polyethylene or composite blade — hard enough to clean, soft enough not to mark the roll cover.
